This happened again under these circumstances: 1) The machine had been up for 5 days.

I haven't seen the problem again since....but twice is problematic with just 3 people using DC. Now. My thoughts about what has been suggested so far, first by Timo: 1) This machine had been booted 5 days before so it's not a boot related problem 2) I'd find it hard to believe that something is nuking the contents of /var/run because: a) The directory doesn't exist by default in AIX; I created it for the DC install b) I have cron jobs that do cleanup with /var/log, /var/log/arc and /var/spool/mqueue, but nothing that does anything to /var/run 3) /var/run is local to the DC host and is not exported 4) funkypunkydrunky's comments about interaction with the MTA (sendmail in my case) seem unlikely, since it doesn't use SSL...or the same ports My questions: 1) What is happening? This is OpenSSL related, yes? 2a) Will this affect my production UWIMAP (which also supports/utilizes SSL)? If it doesn't, I can take my time debugging it (given that there are only 3 IT guys using DC currently), instead of frantically shutting it up by rebooting ASAP. I /think/ previously established DC connections continued to work 2b) How will this affect other imaps DC nex and pre-extant connections? I'm thinking of putting the whole IT dept on DC, but it'd be good to know how flaky things would get if/when this happens again. 3) What can I do to debug it, given that it happens infrequently and of no known causation? What should I check and look for afterwards? I guess I could put a cronjob that checks that /var/run/dovecot/login/ default= and ssl-parameters.dat exists periodically ==== Stewart Dean, Unix System Admin, Henderson Computer Resources Center of Bard College, Annandale-on-Hudson, New York 12504 sdean(a)bard.edu voice: 845-758-7475, fax: 845-758-7035

[Dovecot] per user quota using LDAP entries
by Kenneth Oncinian 22 May '07

22 May '07

Hi List, This is my first post to this list so please be gentle :-). First of all, kudos to the developers of dovecot! Im trying to implement quota, and I followed the instructions in the wiki. My problem is the quota specified per user is not being honored, only the global quota setting. I do have an "quota = maildir:storage=204800" in the plugin area and enabled quota in the mail_plugins for both imap and pop3. This is my user attribute in /etc/dovecot-ldap.conf: user_attrs = homeDirectory=home,uidNumber=uid,gidNumber=gid,mailQuota=quota wherein the "mailQuota" attribute has an entry of "mailQuota: maildir:storage=30720". So i was expecting of a 300MB quota for that user, but dovecot is using the global quota of 200MB instead of 300MB. My dovecot version is 1.0.0 My dovecot.conf: ----------------------- # /etc/dovecot.conf log_path: /var/log/dovecot.log protocols: imap pop3 login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login login_greeting_capability(default): yes login_greeting_capability(imap): yes login_greeting_capability(pop3): no mail_location: /var/mail/vhost/%u mail_debug: yes maildir_copy_with_hardlinks: yes maildir_copy_preserve_filename: yes mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugins(default): quota imap_quota trash mail_plugins(imap): quota imap_quota trash mail_plugins(pop3): quota mail_plugin_dir(default): /usr/lib/dovecot/imap mail_plugin_dir(imap): /usr/lib/dovecot/imap mail_plugin_dir(pop3): /usr/lib/dovecot/pop3 pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: verbose: yes debug: yes debug_passwords: yes passdb: driver: ldap args: /etc/dovecot-ldap.conf userdb: driver: passwd userdb: driver: ldap args: /etc/dovecot-ldap.conf userdb: driver: prefetch plugin: quota: maildir:storage=204800 trash: /etc/dovecot-trash.conf --- my dovecot-ldap.conf ------------------------------------------ hosts = localhost.localdomain dn = "cn=Directory Manager" dnpass = "xxxxxx" tls = no auth_bind = no ldap_version = 3 base = ou=people, dc=xx, dc=xx, dc=xx user_attrs = homeDirectory=home,uidNumber=uid,gidNumber=gid,mailQuota=quota pass_attrs = uid=user,userPassword=password pass_filter = (&(objectClass=posixAccount)(uid=%u)) default_pass_scheme = LDAP-MD5 -------------- sample LDAP query: ------------------------------ ldapsearch -x -Z '(uid=kenneth.oncinian)' # LDAPv3 # base <> with scope sub # filter: (uid=kenneth.oncinian) # requesting: ALL # # kenneth.oncinian, People, ph.panasonic.com dn: uid=kenneth.oncinian,ou=People, dc=xx,dc=xx,dc=xx givenName: Kenneth sn: Oncinian telephoneNumber: xxx-xxxx loginShell: /bin/bash gidNumber: 2516 uidNumber: 1000 mail: kenneth.oncinian(a)xx.xx.xx facsimileTelephoneNumber: xxx xxxx objectClass: top objectClass: person objectClass: organizationalPerson objectClass: inetorgperson objectClass: posixAccount objectClass: account objectClass: mailgroup objectClass: mailgroupmanagement objectClass: mailgroupmanagement-globalconfig objectClass: mailgroupmember objectClass: mailrecipient objectClass: netscapemailserver objectClass: nsmailclient objectClass: ntuser objectClass: sambaSamAccount objectClass: proxyaccess objectClass: jabberaccess uid: kenneth.oncinian preferredLanguage: en cn: Kenneth Oncinian homeDirectory: /var/mail/vhost/kenneth.oncinian ou: Information Systems Department (ISD) x500UniqueIdentifier: mailAlternateAddress: koncinian(a)gmail.com ntUserDomainId: kenneth.oncinian ntUserCreateNewAccount: true ntUserDeleteAccount: true sambaSID: S-1-5-21-1685363153-499155089-1962420841-3000 sambaPrimaryGroupSID: S-1-5-21-1685363153-499155089-1962420841-3001 displayName: Kenneth Oncinian sambaPwdMustChange: 2147483647 sambaPasswordHistory: 00000000000000000000000000000000000000000000000000000000 00000000 sambaAcctFlags: [U ] myproxyaccess: yes myjabberaccess: yes sambaPwdCanChange: 1179303932 sambaLMPassword: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx sambaNTPassword: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx sambaPwdLastSet: 1179303932 mailQuota: maildir:storage=30720 # search result search: 3 result: 0 Success # numResponses: 2 # numEntries: 1 -- snip-- thanks and best regards, Kenneth

[Dovecot] Something about IMAP log
by Mu-Cheng Hsieh 22 May '07

22 May '07

Hi When the user used POP3 to handle her/his mailbox, we could know something happened as below. May 16 10:16:29 server dovecot: [ID 107833 local5.info] POP3(user): Disconnected: Logged out top=675/723063, retr=0/0, del=1/675, size=18124546 However, if the user used IMAP, we can not know what happened. May 18 15:25:42 server dovecot: [ID 107833 local5.info] IMAP(user): Disconnected: Logged out Is it possible to log something (e.g. delete or expunge) through IMAP? Thanks. -- Mu-Cheng Hsieh

It makes for a very ugly userdb query trying to get that formatted to dovecot style of "maildir:storage=48828:ignore=Trash" How much would it take to allow dovecot's quota plugin to alternately accept "maildir:50000000S:ignore=Trash"? -- Kenny Dail <kend(a)amigo.net>

[Dovecot] Conflict -> Dovecot + Maildrop (maildirsize)
by Roberto Gonzalez Azevedo 21 May '07

21 May '07

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I'm having some problems with quota from sql (maildir++) and dovecot + maildrop. I'm using maildrop for MDA and dovecot as IMAP server. When an e-mail arrives, maildrop calculates the quota and updates the 'maildirsize' file. When i use dovecot (webmail, thunderbird) it updates the 'maildirsize' too, overwriting it, but in a different way. Both programas don't use the same pattern for 'maildirsize'. Let me show: 'maildirsize' with maildrop: " 1073741824S 117395679 1760 3675 1 3675 1 1610 1 1612 1 3222 2 9641 1 9641 1 5301 1 6415 1 11716 2 15419 1 15419 1 " 'maildirsize' with dovecot: " 1099511627776S 585847701 102542 5504023 959 " In both examples the quota is 1GB (1073741824S). And now ? Does anybody known how to fix that ? thanks - -- - ---------------------------- Roberto Gonzalez Azevedo Rio de Janeiro, Brazil -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (GNU/Linux) iD8DBQFGQcttF+EMwkXLsEwRAoUOAKC0VXeC4USHyxOhsE5TQixk77hpmwCgxk5P ABOk8XHurCx/gEnd5StCkB8= =B+0f -----END PGP SIGNATURE-----

[Dovecot] LDAP for Virtual Domains
by Bryan Vyhmeister 21 May '07

21 May '07

Is anyone using LDAP along with Dovecot where mail is being accessed in the form of /var/vmail/${domain}/${user}? I have not figured out how to extract the domain from LDAP in order to make this work. I know this is sparse information but maybe there is an easy fix. If not, I can post more information. Bryan

[Dovecot] NFS lock contention for dovecot-uidlist
by Doug Council 21 May '07

21 May '07

We are in the process of migrating away from Courier-IMAP/POP3 and Maildrop. I want to use Dovecot (LDA, IMAP, POP3). During my testing, it has worked great except for dotlocking on the dovecot-uidlist file. The problem: When a delivery is being made with deliver and a mail client has the mailbox open (Thunderbird in this case), neither Thunderbird or deliver can get a dotlock on the dovecot-uidlist file, causing both deliver and Thunderbird to hang until the dotlock timeout runs out and the lock gets replaced. Once the lock is replaced, both will go about their business until the next lock miss and hang again. Eventually, everything is delivered and Thunderbird wakes up. Looking at each of the processes with truss, they are looping trying to stat the dotcot-uidlist.lock file, which no longer exists. We are using NFS, and based on reading through the mailing list archives, it can be a little difficult to get working reliably. But, I've read quite a few posts with our same or similar configuration having good luck with the setup. To reduce multiple box access-issues for now, I've been doing all testing with a single NFS client. Our configuration: NetApp filers for storage FreeBSD 6.2-RELEASE NFS clients Postfix 2.3.9 MTA Dovecot 1.0.0 LDA for local deliveries Dovecot 1.0.0 IMAP for pickup My dovecot.conf file is at the end of this message. NFS access cachcing on the FreeBSD has been disabled (vfs.nfs.access_cache_timeout = 0, see NFS mount options below). Postfix destination recipient and concurrency limit for the Dovecot LDA is set to 1. The NFS mount options: rw,tcp,-r=32768,-w=32768,nfsv3,dumbtimer,noatime,acregmin=0, acregmax=0,acdirmin=0,acdirmax=0 The dovecot.conf file: protocols = imap imaps pop3 pop3s disable_plaintext_auth = no syslog_facility = local0 ssl_cert_file = /nethere/conf/dovecot/ssl-nh-cert.pem ssl_key_file = /nethere/conf/dovecot/ssl-nh-key.pem login_greeting = Server ready. login_log_format_elements = user=<%u> ip=[%r] method=%m encryption=%c pid=%p login_log_format = %U$: %s mail_location = maildir:~/Maildir:INDEX=MEMORY mmap_disable = yes dotlock_use_excl = no lock_method = dotlock first_valid_uid = 200 last_valid_uid = 200 first_valid_gid = 200 last_valid_gid = 200 maildir_copy_with_hardlinks = yes namespace private { prefix = INBOX. inbox = yes } protocol imap { login_executable = /usr/local/libexec/dovecot/imap-login mail_executable = /usr/local/libexec/dovecot/imap imap_client_workarounds = outlook-idle delay-newmail } protocol pop3 { login_executable = /usr/local/libexec/dovecot/pop3-login mail_executable = /usr/local/libexec/dovecot/pop3 pop3_uidl_format = UID%u-%v pop3_client_workarounds = outlook-no-nuls oe-ns-eoh } protocol lda { postmaster_address = postmaster(a)nethere.com sendmail_path = /usr/sbin/sendmail auth_socket_path = /var/run/dovecot/auth-master syslog_facility = mail } auth_executable = /usr/local/libexec/dovecot/dovecot-auth auth default { mechanisms = plain digest-md5 cram-md5 passdb ldap { args = /nethere/conf/dovecot/dovecot-ldap.conf } userdb ldap { args = /nethere/conf/dovecot/dovecot-ldap.conf } user = root socket listen { master { path = /var/run/dovecot/auth-master mode = 0600 user = mailuser group = mailuser } } } It may just be "how it works", but the lock contention seems a little too fragile for busy mailboxes. Does anyone have any ideas? Thanks in advance for any assistance. -Doug

I just asked Pascal as well how he gets around Postfix asking for mailacceptinggeneralid in order to allow messages to be accepted. How do you get around that? Dovecot is working fine but I can't get Postfix to accept messages because it keeps trying to find mailacceptinggeneralid. Bryan

[Dovecot] per-user delivery to commands
by martin f krafft 20 May '07

20 May '07

Hi, we are using dovecot IMAP in a complex virtual setup with almost 4000 accounts; postfix hands over to deliver for local delivery into a home directory as stored in the SQL database. That's /srv/vmail/$DOMAIN/$LOCALPART for most of them, but I'd rather not hardcode this scheme anywhere as it's in SQL. By a policy change, we need to insert a filter in this chain and the filter must be called in such a way that it knows where to find the "home" directory since the command needs to read a configuration file in ~/.mailfilt.rc. Thus I am looking for a way to make deliver pass incoming messages via this filter, but I cannot find any way to do that. Ideally I want this to happen before the LDA runs the mail through sieve. As an alternative, is there a command I can call to make dovecot look up $HOME for me so that I can use the dovecot data in the SQL database without making assumptions about the representation? A command that would proxy and convert my request into an SQL select as per dovecot.conf and feed back the result? Then I could use a Maildir delivery programme or even procmail to do the delivery according to the dovecot configruation. Thanks for any insights, hints, tips, help, jokes, flames, and useful information. -- martin; (greetings from the heart of the sun.) \____ echo mailto: !#^."<*>"|tr "<*> mailto:" net@madduck spamtraps: madduck.bogus(a)madduck.net will kill for oil!

[Dovecot] CVS to Mercurial switch
by Timo Sirainen 20 May '07

20 May '07

I've been meaning to switch away from CVS for a few years now, but I was never sure what I wanted to switch to, so I kept delaying it. I finally decided yesterday that Mercurial is pretty nice. The Mercurial repository is available from http://hg.dovecot.org/ (has a nice web interface). I wrote a small Mercurial mini-howto below. I'm not a Mercurial expert yet, so if you know better ways to do some things please let me know. The CVS repositories will still exist for a while, but they won't be updated anymore. If you notice the CVS being referenced somewhere (wiki, docs, etc.) please let me know (or fix yourself in wiki). 1. Fetch the initial repository: - ex. CVS HEAD: hg clone http://hg.dovecot.org/dovecot/ - ex. branch_1_0: hg clone http://hg.dovecot.org/dovecot-1.0/ - sieve plugin: hg clone http://hg.dovecot.org/dovecot-sieve-1.0/ The Sieve plugin currently works only with v1.0. I'll make a new "dovecot-sieve" repository for CVS HEAD later. 2. Update the repository: hg pull hg merge # only needed if you had done any changes hg update # to actually see the pulled changes All of this can be done with fetch extension. You can enable it by adding to ~/.hgrc: [extensions] hgext.fetch = After that you can use "hg fetch" which does all the above 3 commands (as far as I know, haven't really tried yet). 3. If you want to modify the sources, add your name to ~/.hgrc so it goes nicely into changelogs: [ui] username = Timo Sirainen <tss(a)iki.fi> You're able to "hg commit" your own changes into your repository. If you want to publish them, use "hg log" to see the changeset ID, and then use "hg export changesetid" to get patch ("hg export tip" might work too if you just want the last change(?)). You can then email the patch to Dovecot mailing list to get it merged. With CVS the ChangeLog file was updated every 15 minutes. Now the ChangeLog file doesn't exist in the repository at all. Instead it's generated with "hg log --style=changelog" when running "make dist".

[Dovecot] IMAP "freezing" on OSX
by Ben Carter 20 May '07

20 May '07

Hi, I've got a problem with dovecot on an Intel Mac OSX box. Basically, I was running an older verion (0.8.?, I think), and everything was fine. Then, when I upgraded to 1.0.0 via MacPorts, I found that periodically the system gets into a state where it simply stops dealing with IMAP requests. This tends to manifest itself as Thunderbird simply stalling, not fetching any new messages or folder contents. Sometimes quitting and restarting Thunderbird will help, but at other times the problem persists even afterwards. It seems to be linked to specific mailboxes (or messages?) - often one "problem folder" will reproduce the effect 100% whilst operating on the rest of the mailbox is fine. The problem /seems/ to often start as a result of trying to move messages between folders. I'm not certain if that's a root cause, though, or simply a consequence of "opening" an affected folder to perform the move. I have a spam folder with a large number (>10000) of messages in it, and trying to file stuff in there is a relatively surefire way to generate the problem. Once it's happened once, it inevitably escalates - restarting the client helps a bit, as does restarting dovecot. However, the only way to "fix" it and restore full functionality seems to be to delete all of the index and dovecot* files from the mailbox and folders... it generally takes a day or so after that before things start to go wrong again. All of this seems to point to corruption of the index files in some way, but the log is universally unhelpful - there are no error messages of any kind showing up there. The actual dovecot instance doesn't appear to crash or even "hang" properly - you can still make inbound IMAP connections OK, it's just that they don't ever give a response to commands that touch the affected mailboxes. Sometimes, I end up with temporary files lying around in the folders in the mailbox - apparently mails which were in the process of being moved when the server "gave up". I'm not sure if this is actually part of the problem, though, or just a symptom. My configuration (from dovecot -n) is: # /opt/local/etc/dovecot/dovecot.conf ssl_disable: yes disable_plaintext_auth: no login_dir: /opt/local/var/run/dovecot/login login_executable: /opt/local/libexec/dovecot/imap-login mail_location: maildir:~/Library/Mail/IMAP auth default: passdb: driver: pam args: * userdb: driver: passwd I'm running this on my personal machine, so there's only one user on the system, which I have set up using MailDir (on HFS). There's a fair bit of mail in many of my folders, but I doubt that's the problem as the previous version didn't seem to have any issues... I'm doing mail delivery using postfix directly into the maildir folders. That doesn't seem to be affected at all by this, though - mail still arrives fine even when Dovecot is failing to serve the folder contents to IMAP clients... you just can't see it ^-^ Has anyone seen an effect like this? Or does anyone have any pointers as to what I could try to debug it? Any suggestions would be very greatly appreciated! Thanks! -- Ben Carter - ben(a)gunk.demon.co.uk / ben(a)saillune.net (preferred)

[Dovecot] Thinking Outside the Box - Extending IMAP
by Marc Perkel 19 May '07

19 May '07

Here's some thoughts I'd like to throw out there. I know it's not standard IMAP protocol but someone has to try new ideas first and I want to see what people (Timo) think of this. IMAP establishes a connection between the client and the server. Wouldn't it be great if it could be a conduit to let custom Thunderbird plugins talk to custom server application over the IMAP interface? For example, personalized server settings. Suppose for example I want Thunderbird to edit my server side white lists or black lists or any other setting? Wouldn't it be nice if IMAP supported these changes? The connection is made. It's a secure connection that's been authenticated. Lets use it! Here's my initial thoughts on this. Suppose we extended IMAP to include an EXECUTE command as follows: EXECUTE command parameter, parameter .... On the server side is a config file that has the commands that execute will allow and what programs they run. When the execute command is seen by Dovecot then Dovecot runs the program in the list with the parameters passed. For example, suppose there is a command to add a user to a server side blacklist. 100 execute blacklist add joe(a)smith.com 100 ok Dovecot would open a two way connection to the server application allowing the client to talk to any application that is configured and can send and receive text. The connection persists until the server end terminates or the client closes the connection. With a tool like this one can write generic applications easily that would greatly expand what email clients can do interacting with the server. Not only can setting be changes but you could interact with server side calendars, pick up voice messages from phone systems, run any sort of groupware, all over a generic IMAP connection with this simple extension. Example: 100 EXECUTE calendar 100 ok 100 list schedule today 8:00 10:00 100 8:00 make coffee 100 9:00 meeting with boss 100 9:30 Call Joe Blow at 415-555-1212 100 ok 100 quit 100 ok One thing I'd like to use it for is an outgoing SMTP connection to send outgoing email over IMAP. A session might look like this: 999 EXECUTE smtp 999 220 darwin.ctyme.com ESMTP Exim 4.67 Sun, 13 May 2007 06:52:26 -0700 999 helo ctyme.com 999 250 darwin.ctyme.com Hello localhost [127.0.0.1] 999 mail from:marc@perkel.com 999 250 OK 999 rcpt to:dovecot@dovecot.org 999 250 Accepted ...... 999 quit 999 OK Who likes this idea?

[Dovecot] [Fwd: An invitation to the "morg" (Message Organization) mailing list]
by Luigi Rosa 19 May '07

19 May '07

This messages has been posted on SquirrelMail development mailing list. Maybe someone is interested in morg mailing list. Ciao, luigi -------- Original Message -------- Subject: [SM-DEVEL] An invitation to the "morg" (Message Organization) mailing list Date: Sat, 19 May 2007 17:08:03 +0300 To: squirrelmail-devel(a)lists.sourceforge.net Hello all, [Note: Yes, I'm not gone after all... There has been a change of plans! I'll be mostly active, time permitting] There is a new IETF effort on IMAP standards, continuing on the work of "IMAPExt" Working Group which has practically closed now. I'm sending this here because people might be interested in joining it and either contributing actively or simply keeping an eye on what will be available in IMAP servers soon. Personally I'm very interested on message and mailbox annotations / metadata, but some other stuff like dynamic, multi-mailbox, persistent searches and virtual mailboxes might be of more interest to you. Anyway, you can join this effort by subscribing to the morg mailing list: https://www1.ietf.org/mailman/listinfo/morg http://www.ietf.org/maillist.html To quote Dave Cridland about the purpose of the list: ====== Quote start ======== This list has been created to look carefully at how existing mail clients search through, sort, and generally organize email. We're also going to - hopefully - have client developers talk about what they'd like to be able to do. There's another group that might be interested in this, too - the "desktop search" people might well be interested in the ability to search effectively through remote message stores. Kjetil commented (on IMAPEXT) that this area might be very interesting to IMAP webmail people, who can't simply download everything and work locally, so if there are any IMAP webmail developers about it'd be interesting to hear from you, and if anyone knows any, please invite them to join. Meanwhile, we're also going to look at what features we have on the store - the IMAP server - that we can leverage for this. There's a number of RFCs and Drafts in the area of searching, organization, etc, and we'll need to ensure we're all aware of the current state of play. So, IMAP specialists need to start to enumerate these - any volunteers? It occurs to me that both the above might benefit from a Wiki page or two - Lisa, is there an Apps Wiki we can use for this, or should I just set one up? [For anyone new to the IETF, Lisa and Chris are the Applications Area Directors] Finally, we'll look at what new work we can do to satisfy client requirements, write up a draft charter, and move to BOF (the first stage in forming a new IETF working group), aiming to form a new working group to do the work, and produce RFCs as we decide is appropriate. I'd like to take a decision on going down this road after Chicago in the summer, hopefully ready for a BOF at the IETF in December. I personally think our ultimate output is likely to be some Standards Track and some Experimental specifications for extensions, and maybe a couple of Informational documents on how this stuff ties together. I'd also note that searching is something that, like a lot of IETF work, has patent minefields in places - please do read that Note Well stuff, and let us know of any IPR you're aware of as soon as you can. ====== Quote end ======== -- / +--[Luigi Rosa]-- \ Sheridan: We have an open door policy. Ivanova: And an open airlock policy. --"The Illusion of Truth", Babylon 5

[Dovecot] Maildir subfolder conversion from courier-imap
by Remy Blank 19 May '07

19 May '07

Hello, I am trying to convert a maildir that was managed by courier-imap up to now to dovecot. I am using the courier-dovecot-migrate.pl script as follows: courier-dovecot-migrate.pl --convert --recursive ~/Maildir However, this command only seems to convert the base maildir, but not all the subfolders. I thought that that's what the --recursive option was for. Is the command above supposed to convert the base maildir as well as the subfolders, or should I run the command on all subfolders separately (e.g. using a shell script)? Thanks. -- Remy

One of the problems with the clustered file system approach seems to be that accessing Dovecot's index, cache and control files are slow over the network. For speed, ideally you want your index, cache and control on local disk... but still replicated to another server. So what about tackling this replication problem from a different angle... Make it Dovecot's job to replicate the index and control files between servers, and make it the file system's job to replicate just the mail data. This would require further disconnecting the index and control files from the mail data, so that there is less syncing required. i.e. remove the need to check directory mtimes and to compare directory listings against the index; and instead assume that the indexes are always correct. Periodically you could still check to see if a sync is needed, but you'd do this must less frequently. I agree that there are already great solutions available for replicated storage, so this would allow us to take advantage of these solutions for the bulk of our storage without impacting the speed of IMAP.

Perhaps that would be good enough, yes. > Yes, I think treating mailboxes similary to keywords is ideal. There really is no reason to physically separate mailboxes on disk. All that is needed is this logical separation if it can be done in a reliable way. Or maybe track this in mailbox-specific index files, and also have a corespodning text file that stores a list of messages that are contained in that mailbox... similar to maildir's dovecot-uidlist file. Then if you lose the index you can rebuild the index from the text file. Bill

[Dovecot] dovecot-shared being ignored?
by bhayden＠umn.edu 19 May '07

19 May '07

So, I'm working on a shared folder. Everything is nice except for one bit. My dovecot-shared file in the Maildir is either being ignored, or doesn't work the way I think it does. Any messages copied into the Maildir using a mail client are mode 660 and owned by the user who did the copy. Perms on the dovecot-shared file are 700 (I'm using Solaris ACLs in addition to the Dovecot ACLs in order to prevent unauthorized access via means that don't pass through Dovecot's IMAP server... ie SFTP/SCP, and so I'm using 700 with a rwx mask and access to the file set per user in the Solaris ACL). The message files being created 660 means they are accessible via SFTP/SCP to anyone in the group, and we have a single one for (nearly) all users. This is not really acceptable, so if anyone can offer guidance on the dovecot-shared that'd be great. I checked the wiki, and it has very minimal information. -Brian

[Dovecot] Virtual mailbox plans
by Timo Sirainen 18 May '07

18 May '07

Configuration ------------- There could be global and user-specific configuration files, similar to how ACLs work. I think the global virtual mailboxes should be only defaults though, so that users could delete them and create a new mailbox (virtual or non-virtual) with the same name. The global virtual mailboxes could be described in a single file, such as: Trash deleted Work/My Unseen (mailboxes "box1" "box2" "box2/*") or to "tss(a)iki.fi" to "timo.sirainen(a)iki.fi" unseen So the format would be <virtual mailbox name> LF <search condition, allowed to wrap to new line> LF LF <next virtual mailbox, etc.> Per-user virtual mailboxes could also be listed in a similar file. If the search condition is empty, a globally defined virtual mailbox has been deleted. Another way would be to have per-mailbox dovecot-virtual files, but I'm not sure how global virtual mailboxes could then be easily deleted. Also having all of them in a single file makes listing the mailboxes pretty fast. The search condition would be a standard IMAP SEARCH reply, with the exception of the mailboxes parameter to specify what mailboxes are used. Virtual mailboxes would be implemented as a new mail storage backend, so their namespace configuration would be like: namespace private { prefix = "virtual/" location = virtual:~/virtual:GLOBAL=/etc/dovecot/virtual-globals.conf } Syncing ------- ~/virtual directory would contain index files for the virtual mailboxes. If the index files don't exist, a full resync for the virtual mailbox is done. This means opening all the real mailboxes configured for the vbox, running the SEARCH command and adding the returned UIDs to the vbox's indexes. The index would contain at least mailbox ID and message UID numbers. Probably would be a good idea to also save UIDVALIDITY numbers just to be safe, although that's a bit of a waste of space and it could be handled in other ways too, such as changing the mailbox ID whenever its UIDVALIDITY changes.. Mailbox IDs would be mapped to names in mailbox list index. This index already exists, although there still seems to be some bugs in it. At least creating a new list index has a race condition. I should look into making the list index a bit more realiable. Also the list indexes work only with Maildir++ layout currently. After the vbox has initially been synced, it needs to also handle updates. I think optionally the updates could be done the same way as full sync (opening all mailboxes to see if there are changes), but a faster way would be to update the virtual mailboxes immediately when the real mailboxes are being modified. So IMAP, POP3 and deliver all need to be aware of the virtual mailboxes and what real mailboxes are mapped to what virtual ones. Whenever doing a change that causes the message to either be added to or removed from a virtual mailbox according to their rules, the virtual mailbox's index is updated immediately. Being able to determine this change quickly might be the biggest change required to Dovecot's base code. Changes ------- Virtual mailboxes would share their state with the real mailbox, so any flag changes done in the vbox would be immediately changed in the real mailbox as well. The same goes for expunges. Virtual mailboxes' transaction logs would use different records for expunges and removals. Expunges would be handled normally, but removals wouldn't be removed from the in-memory view of the mailbox until EXPUNGE command was given (although they would be removed from dovecot.index immediately, so new sessions wouldn't see them). This makes it possible to have a vbox with only unseen messages, but without the message getting expunged immediately after a client opens the mail. So the EXPUNGE command could act as a "session synchronization" command. And of course it would also expunge the messages that had been marked as \Deleted.

[Dovecot] deliver exit codes?
by Ralf Hildebrandt 18 May '07

18 May '07

Before switching to dovecot deliver for all local deliveries, I'm calling deliver from maildrop (yes, don't laugh). Snippet from my global /etc/maildroprc: # Store maillist & junk messages directly /^Precedence: ?list/ if ( $MATCH ) { exception { log "Bulk message: $MATCH" #to "$DEFAULT" to "|$DELIVER" } } I replaced to "$DEFAULT" (meaning: delivery to $HOME/Maildir) with to "|$DELIVER" (meaning: pipe the mail into dovecot deliver, and deliver to INBOX = $HOME/Maildir) This works really well, UNLESS a user exceeds his/her quota: In that particular case, deliver fails to deliver the mail and generates a bounce, all on it's own. It's exit status is 0 in that case, so my MTA (postfix) thinks that the mail has been delivered successfully. I'd prefer deliver to return EX_TEMPFAIL, which I can pass through maildrop back to postfix, which will then log a temporary error and will bounce the mail all by itself after 5 days time.

Dbox definitely sounds promising. I'd avoid putting this uid-<nextuid> file in the same location as the mail storage though, because if you can truly keep mail storage isolated and infrequently accessed, then you can do cool things like store your mail data remotely on Amazon S3 or equivalent.

[Dovecot] Processing too fast?
by Daniel L. Miller 17 May '07

17 May '07

I'm trying to use Dovecot to make administering ASSP a bit easier. I've created a mailbox with a number of subfolders (Spam, Ham, etc.) and have ASSP setup to save mail in the appropriate folder e.g. /var/mail/ASSP/.INBOX.Ham/new. But I'm having problems with ASSP complaining about the newly created files - I believe the file gets opened, then it disappears before ASSP finishes writing to it. Is Dovecot grabbing the file from "new" and moving it to "cur" faster than ASSP can write? How can I get around this? ASSP only allows for a folder to save each category to - I can't specify an LDA. -- Daniel

[Dovecot] dbmail benchmarking

I thought I'd try benchmarking with dbmail (v2.2.4) to see how much slower a SQL backend could actually be. Skip to bottom for the conclusions. Originally I ran the tests with the databases being in XFS filesystem. MySQL's performance was horrible. It went 3-7x faster with ext3.

So apparently there's some PostgreSQL-specific bug in dbmail. The same values with Dovecot 1.0 + maildir: ./imaptest clients=1 - append=100 seed=1 secs=30 msgs=1000000 logout=0 Logi Sele Appe 100% 100% 100% 5% 1 346 364 ./imaptest clients=5 - append=100 seed=1 secs=30 msgs=1000000 logout=0 Logi Sele Appe 100% 100% 100% 5% 5 1408 1470 ./imaptest clients=1 seed=1 secs=30 msgs=1000000 logout=0 Logi List Stat Sele Fetc Fet2 Stor Dele Expu Appe 100% 50% 50% 100% 100% 100% 50% 100% 100% 100% 30% 5% 1 130 133 259 258 382 123 127 257 271 ./imaptest clients=1 seed=1 secs=30 msgs=1000000 logout=0 fetch=0 Logi List Stat Sele Fet2 Stor Dele Expu Appe 100% 50% 50% 100% 100% 50% 100% 100% 100% 30% 5% 1 155 163 339 478 169 175 338 354 So, what are the conclusions? - In raw append speed dbmail is almost as fast as maildir. - In raw read/write speed maildir is about 1,6 times faster - When adding metadata fetches Dovecot is 4 times faster than dbmail. This is most likely because dbmail doesn't have a cache equivalent to dovecot.index.cache so it has to do the fetches the slow way. I would have liked to also run the generic tests with more than 1 client, but then I start hitting dbmail bugs and the test stops (reported already to their bugtracker).

[Dovecot] OS X Mail Administration
by Bruce Bodger 16 May '07

16 May '07

I'd like to request some feed back from any OS X Mail Admins on the list, please. Currently running 10.4.9 here using postfix / dovecot and I'm about to take the plunge from mbox to maildir. I just migrated from uw-imap to dovecot. As you're aware, users inbox's are customarily stored in /var/mail/% username and personal folders under /Users/%username/Library/Mail/IMAP. I'd appreciate if you'd share with me the directory structure that you use, or would use in my situation. All mail storage will be on the server so disk space is not an issue. I'm a bit confused whether or not to keep the inbox separate from the other imap structure as is the OS X default: should all mailboxes be under inbox, etc. Your input would be appreciated. Thank you, B. Bodger New York, NY

[Dovecot] Login with firstname.lastname instead of loginname
by Ralf Hildebrandt 16 May '07

16 May '07

Some of our users use to login as firstname.lastname or firstname.lastname(a)charite.de instead of using the "correct" "flastname" login name. In order to get this behaviour a long-gone co-worker wrote an authdaemon.pl, which speaks the courier-authdaemon protocol. How can I emulate this behaviour with dovecot? Basically, all I need is a usernamen mapping ala: Ralf.Hildebrandt(a)charite.de rhilde Ralf.Hildebrandt rhilde for all my users -- I can generate this programatically using awk, but how can I make dovecot use that? -- Ralf Hildebrandt (i.A. des IT-Zentrums) Ralf.Hildebrandt(a)charite.de Charite - Universitätsmedizin Berlin Tel. +49 (0)30-450 570-155 Gemeinsame Einrichtung von FU- und HU-Berlin Fax. +49 (0)30-450 570-962 IT-Zentrum Standort CBF send no mail to plonk(a)charite.de

[Dovecot] Sorting by Received vs Sent
by Bill Boebel 16 May '07

16 May '07

Looks like in Cyrus, sorting by Received date is faster than sorting by the Sent header date because of the way they use the index and cache files... http://www.emaildiscussions.com/showpost.php?p=419246 Is this the case in Dovecot as well? Bill

[Dovecot] Deliver sending bounces from 'MAILER-DAEMON@'
by Erland Nylend 16 May '07

16 May '07

Hello, I'm having a problem with postfix and/or dovecots "deliver". I'm getting these lines in the mail log: | Apr 24 11:42:08 smtp2 postfix/qmgr[6176]: 05BAE3B67E: from=<>, size=3055, nrcpt=1 (queue active) | Apr 24 11:42:08 smtp2 postfix/qmgr[6176]: 05BAE3B67E: to=<MAILER-DAEMON@>, relay=none, delay=0.01, delays=0.01/0.01/0/0, dsn=5.1.3, status=bounced (bad address syntax) After some debugging, it seems that those lines in the log appear if I send mail to an account which is over quota. (I'm using the Maildir++ quota) This is from my dovecot.conf: | protocol lda { | postmaster_address = MAILER-DAEMON(a)my.domain.tld | mail_plugins = quota | auth_socket_path = /var/run/dovecot/auth-master | hostname = my.mail.server | sendmail_path = /usr/sbin/sendmail | } It seems to me that dovecot is sending bounce messages from 'MAILER-DAEMON@' .. Does anyone know why this is happening, or how I can specify the address to be used? I'm using dovecot 1.0.0. -- Erland Nylend

[Dovecot] Thunderbird or Dovecot bug? (multiple keywords)
by Troy Engel 15 May '07

15 May '07

Here's a strange one. I have a user who's using Thunderbird 2.0.0 and assigning multiple tags (keywords) to emails, which are getting "lost" (I'll explain) when he leaves the folder and comes back. I can reproduce this on *his* account myself, but cannot reproduce it on *my* account (separate new TBird 2.0.0 profiles on Windows XP). Use the two TBird default tags 'Important' and 'Work' for all these tests, which it refers to as $Label1 and $Label2 in IMAP-keywords land. If I go into my account, label an email with both tags, it sticks -- I can click on Drafts then back to Inbox, and both tags/keywords still show in the client. If I go into his account, add the two tags, then click on Drafts and back on Inbox, only the *second* tag (Work, $Label2) shows. If I remove that tag, then the first tag (Important, $Label1) immediately pops up! On the backend the actual Maildir files match the dovecot-keywords and have the correct letter appended in both cases - so, in his account when the email only shows one tag, the physical mail file has the letters for two tags. So Thunderbird should be showing both tags, like it does in my account where everything is working correctly. This leads me to believe that the problem has something to do with the difference of dovecot-keywords content, and the interaction TBird has with Dovecot. My account, working correctly, looks like: dovecot-keywords: 0 $Forwarded 1 $MDNSent 2 $Label2 3 $Label1 file: Maildir/cur/1178712608.H529732P11686.yak.fluid.com:2,RSdc ...which matches, d=$Label1 (Important), c=$Label2 (Work) and TBird is displaying the email as having both tags - all is well and good. Now, his account looks like: dovecot-keywords: 0 Junk 1 NonJunk 2 $Label4 3 $Label1 4 $Label2 5 $Label3 6 $Label5 file: Maildir/cur/1178728930.P28392Q0M960111.yak.fluid.com:2,RSbde ...again, everything matches on the server; yet, it Thunderbird is only displaying $Label2 (d,3). I also noticed something interesting, even if I have the TB 'Junk Controls' completely disabled on his account, and remove all tags using the menu option, that file still retains the 'b' (NonJunk) tag in the filename: Maildir/cur/1178728930.P28392Q0M960111.yak.fluid.com:2,RSb All this long-winded explanation leads me to believe that somehow the difference in dovecot-keywords is causing this problem, but what I can't tell is who's problem it is -- Dovecot, or Thunderbird? Thoughts welcome, -te PS: all the normal things tried like deleting the dovecot index files, Thunderbird cache files and profiles, etc. -- Troy Engel | Systems Engineer Fluid, Inc | http://www.fluid.com

[Dovecot] Why is direct invocation of dovecot preferred over inet inclusion?
by Stewart Dean 15 May '07

15 May '07

I'm used to putting things in inetd and, 1) should dovecot crash, I'd think it would get restarted if it was invoked from inet's imap-login 2) it would get started well after the boot ...wouldn't that be preferable.

[Dovecot] Question: contention with blackberry
by Stewart Dean 15 May '07

15 May '07

My production imap is currently UWIMAP with mbox.. One of the problems commonly observed is mailbox lock loss, which happens when: a) a VIP has multiple secretaries accessing a single mailbox (actually, they are professional enough to have figured the realities of conflicting access and rarely have a problem), b) somebody leaving their machine on at home and coming in and firing up their work computer c) important people with Blackberries....and the BB service polls the mailbox every so often and breaks the lock. In any case, the maillog ends up with a message like this: > May 5 19:45:04 mercury mail:info imapd[2035774]: Logout user=xxxxx host=bda056.bis.na.blackberry.com [216.9.249.56] > May 5 19:46:52 mercury mail:info imapd[2502902]: Killed (lost mailbox lock) user=xxxxx host=cpe-24-161-103-11.hvc.res.rr.com [24.161.103.11] How will this work with Dovecot? I regard what is happening now as OK, working as designed. Although we may eventually move to a different mailbox format, I am only switching from UW to DC in the first step. -- ==== Stewart Dean, Unix System Admin, Henderson Computer Resources Center of Bard College, Annandale-on-Hudson, New York 12504 sdean(a)bard.edu voice: 845-758-7475, fax: 845-758-7035

[Dovecot] Mails, work and so on
by Timo Sirainen 14 May '07

14 May '07

You can probably guess from my flood of mails that I'm no longer busy. I still have a couple of exams but since I haven't spent any time at all studying for them or attending the lectures, I can just as easily leave them for next year. I've read and answered most of the "easy" mails in this list and in my INBOX. I'll try to answer the rest of them this weekend, so no need to forward them to me again, at least not yet. :) Now that I'm finally non-busy, it also appears that I haven't worked for a long time and I'm almost broke. :) So now would be a great time for your corporation to buy/sponsor some Dovecot development. Otherwise I'm probably soon busy with non-Dovecot related work. My own high priority TODO contains: - Get the rewritten Squat full text search index working. It probably needs a name change, since it's not all that close to Cyrus Squat anymore. Suggestions? Could of course be just "fts_dovecot". - Shared mailboxes / ACLs - dbox cleanups and possibly partial redesign. I'll write a separate mail about this later. - Index file code cleanups, simplifications and optimizations. Make it work with NFS with attribute cache enabled.

[Dovecot] How to get rid of locks
by Timo Sirainen 14 May '07

14 May '07

Although Dovecot is already read-lockless and it uses only short- lived write locks, it's be really nice to just get rid of the locking completely. :) I just figured out that O_APPEND is pretty great. If the operating system updates seek position after writing to a file opened with O_APPEND, writes to Dovecot's transaction log file can be made lockless. I see that this works with Linux and Solaris, but not with OS X. Could you BSD people try if it works there? http://dovecot.org/ tmp/append.c and see if it says "offset = 0" (bad) or non-zero (yay). The O_APPEND at least doesn't work with NFS, so it'll have to be optional anyway. Currently Dovecot always updates dovecot.index file after it has done any changes. This isn't really necessary, because the changes are already in transaction log, so the dovecot.index file can be read to memory and the new changes applied on top of it from transaction log (this is pretty much how mmap_disable=yes works). So I'm going to change this to work so that the dovecot.index is updated only if a) there are enough changes in transaction log (eg. 8kB or so) and b) it can be write-locked without waiting. Maildir then. It has this annoying problem that readdir() can skip files if another process is rename()ing them, causing Dovecot to think that the message was expunged. The only way I could avoid this by locking the maildir while synchronizing it. Today I noticed that this doesn't happen with OS X. I'm not sure if I was just lucky or if there really is something special implemented in it, because it doesn't work anywhere else. I'm not sure if this is tied to HFS+, or if it will work with zfs also (Solaris+zfs didn't work). So perhaps the locking could be disabled while running with OS X. More importantly I figured out that it can also be avoided with Linux +inotify. As long as the inotify event buffer doesn't overflow, the full list of files can be read by combining the readdir() output and files listed by inotify events. If the inotify buffer overflows (highly unlikely), the operation can just be retried and it most likely works the next time. So with these changes in place, changing a message flag or expunging a message would usually result in: - lockless write() call to dovecot.index.log - lockless read()ing (or looking into mmaped) dovecot.index.log to see if there's some new data besides what we just wrote that needs to be synchronized to maildir - rename() or unlink() calls to maildir. If a call return ENOENT, the maildir needs to be readdir()ed with inotify enabled to find the new filename. Not a single lock in the operation, assuming that dovecot.index file wasn't updated. Assigning UIDs to newly delivered mails would require locking though. dovecot-uidlist needs to be locked, and the UIDs need to be written to dovecot.index.log file in the correct order, which can also be done with dovecot-uidlist locking. Actually a single write() to dovecot.index.log isn't enough. I think there needs to be some kind of a flag written to the beginning of the transaction which marks the transaction as truly finished. If the flag isn't there, any reader knows to stop and wait until the flag is set. So this means that the writer needs to: 1. Do a single O_APPENDed write() call writing the whole transaction 2. Get the current offset with lseek(fd, 0, SEEK_CUR) (this is what the append.c tester checks) 3. pwrite() the finished-flag to beginning of the transaction Except at least with Linux pwrite() doesn't work if O_APPEND is enabled. There are two ways to work around this: a) fcntl(disable O_APPEND) + pwrite() + fcntl(enable O_APPEND) b) Keep two file descriptors open for the transaction log. First with O_APPEND flag and second without. pwrite() to the second one. a) is probably better because it doesn't waste file descriptors.

[Dovecot] PATCH: sendmail-like DSNs in Dovecot deliver (EX_TEMPFAIL always)
by Steffen Kaiser 14 May '07

14 May '07

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, I've put together an always tempfail & sendmail-like DSN report back patch. Because I don't know how to transform the rejection reason into sysexit.h codes, it always tempfails. The hooks are so that: a) config file setting: lda_mode = mode b) command line: deliver --mode mode where mode is default or sendmail. When no mode is specified, it defaults to "default", which is the current behaviour. In sendmail mode, mail_send_rejection() simply prints the rejection reason to stdout, logs it and returns EX_TEMPFAIL. Ideally, the return value would be specific to the reason. I haven't poked into this deeply, but it doesn't look straight forward.

[Dovecot] header-lines of subfolders have to be rescanned after each client startup
by Rainer Sigl 14 May '07

14 May '07

Hi all, after each startup of my different mail clients (thunderbird, outlook, ...) the contents of subfolders if I click in has to be renewed. This takes some time for large folders. I just migrated from courier. And there all subfolders were available immediately. Is there something to configure? Another effect regarding subfolders is that the client forgets, which subfolders were opened after shutdown and shows the folders closed. This means, that necessary subfolders have to be reopened after each startup. This was managed as well by my previous courier server. Many thanks for answers Rainer Sigl -- ----------------- Rainer Sigl, | email: sigl(a)mpe.mpg.de MPI f. extraterrestrische Physik, | phone: +49 (89) 30000-3557 Postfach 1312, | fax: +49 (89) 30000-3569 D-85741 Garching, Germany | web: http://www.mpe.mpg.de/~sigl/

[Dovecot] v1.1 plans
by Timo Sirainen 14 May '07

14 May '07

I think I won't do any actual releases until it's mostly feature complete. Then maybe v1.1.alpha1 or v1.1.beta1. So if you want to test it before then, use CVS or the nightly snapshots. I'm planning on keeping v1.1 almost completely compatible with v1.0. There could be some minor configuration file changes, but for most people v1.0's dovecot.conf should work with v1.1. I want to update index file handling to use less locks and update dovecot.index file less often. The file formats would still stay backwards compatible with v1.0. After this I'm hoping to get index files working well with NFS even with attribute cache enabled. Dovecot v2.0 then brings incompatible index files and more or less rewritten configuration file handling. It could still support old config file format and settings, but the default will be somewhat different. I'm hoping to release the first alphas/betas in 2-3 months, with v1.1.0 maybe even as early as next summer. The good thing here is that index file code hasn't changed much since v1.0, so it should be stable. The bad thing is that I've added a couple of completely new indexes. I'm also quite busy for the next month, but I'm not sure how much it affects my coding. :) The largest already implemented new features are: + Added support for IMAP UIDPLUS extension + IMAP SORT: Sort keys are indexed, which makes SORT commands faster. + IMAP THREAD: Threads are indexed into a dovecot.index.thread file. It can usually be updated incrementally, so this makes THREAD fast. + Added Dovecot-specific X-REFERENCES2 threading algorithm. It's similar to REFERENCES, but it doesn't do base subject merging and it sorts the threads by their newest message. + When saving messages, update cache file immediately with the data that we expect client to fetch later. Maildir-only currently. + Mailbox list indexes. Mailbox metadata is stored there, so STATUS commands can return synchronized mailboxes' metadata simply by reading a single mailbox list index file. - FIXME: Currently works only with Maildir++ layout. + Expire plugin can be used to keep track of oldest messages in specific mailboxes. A nightly run can then quickly expunge old messages from the mailboxes that have them. The tracking is done using lib-dict, so you can use either Berkeley DB or SQL database. + Namespaces are supported everywhere now. - FIXME: except by convert plugin + Full text search indexing support with Lucene and Squat backends. + OTP and S/KEY authentication mechanisms (by Andrey Panin). + mbox and Maildir works with both Maildir++ and FS layouts. You can change these by appending :LAYOUT=maildir++ or :LAYOUT=fs to mail_location. Features that I'm planning on implementing: - Fully supported shared mailboxes and IMAP ACL extension - Replace Squat FTS indexes with my new design - Case-insensitive searches with non-ASCII text as well - Maybe add support for all kinds of IMAP extensions that can be easily supported. LEMONADE extensions especially: CONDSTORE, CATENATE and maybe even URLAUTH if I can figure out how it should work. If a feature can be implemented completely as a plugin, it could still come in v1.1.beta stage, because it won't destabilize the rest of the Dovecot anyway.

[Dovecot] Feature Request: content-filter / MOVE scripts
by Daniel L. Miller 14 May '07

14 May '07

Since your "1.1 plans" announcement somehow turned into everybody handing in a wish list . . . thought I'd start one by itself - since I expect a few people to have opinions on this matter. I'm aware of a plug-in functionality in Dovecot, and that a plug-in exists for dspam processing - but my review of the plug-ins indicate they require compiling your own Dovecot - the plug-in setup isn't really suitable for packaged distros. As a packaged software user - I really really really don't like compiling my own software, either for features or bugfixes - I want leave that to the experts. On learning of 1.0's official release, I nudged the Debian package maintainers to check - and they were already on it and it updated. Thanx Timo, Jaldhar, and Fabio. I have some thoughts on an interface that would eliminate the need for compile-time plug-ins, but provide some major power to sysadmins. Basically, I want a way of telling an external program the following: 1. A message was moved. 2. The folder is moved from was XXX. 3. The folder it moved to was YYY. 4. The message moved was ZZZ. Armed with this information, just about anybody's spam fighting learn scripts can be called to do their thing. A few different ways have occurred to me: 1. Have a dedicated "content-filter" functionality built-in to Dovecot. Under this model, Dovecot.conf would include at least three new parameters: FILTER-FOLDER-SUFFIX, FILTER-FOLDER-IN-SCRIPT, and FILTER-FOLDER-OUT-SCRIPT. Whenever a message is moved into or out of a folder ending in SUFFIX the appropriate SCRIPT is called, with the arguments above being passed. 2. A bit more generic, less processing for Dovecot. Dovecot.conf parameter ACTION-SCRIPT (hey, feel free to use other names - I'm just brainstorming here). Any time any message is moved anywhere, call SCRIPT with the arguments. Having never looked at Dovecot's code, I'm just guessing, but this probably wouldn't take much to implement - but might be the most performance affecting. 3. Have a definable named-pipe to send the same information to. 4. Have a definable TCP socket to send the same information to. In any case, I figure it's best to prevent any message processing by Dovecot itself - so while it might be nice to define a list of headers to send to the scripts, instead of the whole message, that's probably not appropriate for Dovecot to focus on. On the other hand, any of the above options would probably benefit from a MAXIMUM_FILTER_SIZE parameter to limit the maximum message size. So what's the world got to say about this? (More importantly, how does TIMO feel about this?) ;). -- Daniel

Hello. I've notice a problem with SMTP AUTH in postfix with dovecot. My configuration is based on Postgresql. I've created a function in postgresql which returns password and username and attached it to password_query. Query looks like this password_query = SELECT username_out as username, password_out as password FROM get_password(lower('%n'),lower('%d')); Problem is when get_password returns something like this... vmail=# SELECT username_out as username, password_out FROM get_password(lower(''),lower('')); LOG: statement: SELECT username_out as username, password_out FROM get_password(lower(''),lower('')); LOG: duration: 2.342 ms statement: SELECT username_out as username, password_out FROM get_password(lower(''),lower('')); username | password_out ----------+-------------- | (1 row) It returns 1 empty row.... When this is attached to postfix with smtp auth with such configuration # SMTP AUTH broken_sasl_auth_clients = yes smtpd_sasl_auth_enable = yes smtpd_sasl_security_options = noanonymous smtpd_sasl_authenticated_header = yes smtpd_sasl_local_domain = smtpd_sasl_type = dovecot smtpd_sasl_path = private/auth my serwer starts to be open relay... I now that it returns empty string for username and password... so where is the password checked... if I dont send password as a parameter to my function. Definition of the function looks like this: CREATE FUNCTION get_password("login" character varying, "domain" character varying, OUT username_out character varying, OUT password_out character varying) RETURNS record Can you help with that...

[Dovecot] Public folders using NAMESPACE

I've been mainly focusing on the thread from here: http://www.dovecot.org/list/dovecot/2006-June/013683.html and the wiki ACL documentation: http://wiki.dovecot.org/ACL but I'm having a hard time piecing it all together...

[Dovecot] mailquota in ldap attribute 'mailQuota'

I've tried having the ldap quota in an ldap attribute, which still doesn't work. /etc/dovecot.conf protocols = imap pop3 mail_location = maildir:/data/mail/%u/Maildir protocol imap { mail_plugins = quota imapquota } plugin { quota = maildir:ignore=Trash } the rest are defaults added an attribute 'mailQuota' with value '10240' kbytes or 10Mbytes as for /etc/dovecot-ldap.conf user_attrs = mail,homeDirectory=home,uidNumber=uid,gidNumber=gid,quotaStorage=mailQuota Would appreciate if anyone could assist on this. I'd prefer to use the above than setting the mail quota manually: quota = maildir:storage=10240:ignore=Trash We are actually in the planning stage of migrating all of current our mailboxes from Netscape to Dovecot, instead of upgrading it to those new Sun.

[Dovecot] Deferring, instead of rejecting, messages when at quota
by Mike Brudenell 13 May '07

13 May '07

Greetings - I'm having trouble working out where to alter this behaviour (so please forgive me if it turns out to be an Exim thing rather than Dovecot!)... My test service is using Exim as the MTA and Dovecot's "deliver" for the LDA. We are using Maildir mailboxes with filestore quotas. When I send a large test message to myself that cannot be delivered because I don't have sufficient available quota remaining an error message is immediately returned to the sender and the incoming message discarded. The error message says this: Your message was automatically rejected by Dovecot Mail Delivery Agent. The following reason was given: Not enough disk space Instead of Exim rejecting the incoming message and generating the error response because of deliver's failure to, umm, deliver I'd like the message to be retained in Exim's queue so that it can be retried periodically. With our old/live system (Sendmail + UW IMAP's "tmail" LDA) I edited the tmail source code to return a different exit code: one that caused Sendmail to defer (re-queue) the message rather than reject it. How do I achieve this effect with Exim + deliver please? Is it a case of: * Setting something in Dovecot's configuration file (I can't spot what!); * Changing a return code in deliver's source (if so, whereabouts and to what?); * Or is there an Exim directive I need to add to the transport definition in its configuration file?

[Dovecot] wierd ssl-parameters.dat regeneration error

I just had a strange problem with my Dovecot 1.0 installation. After about two weeks, it logged these messages: dovecot: Error: ssl-build-param: rename(/usr/local/var/lib/dovecot/ssl-parameters.dat.tmp, /usr/local/var/lib/dovecot/ssl-parameters.dat) failed: No such file or directory dovecot: Error: child 30689 (ssl-build-param) returned error 89 And thereafter, all login attempts resulted in this: dovecot: Error: imap-login: read(ssl-parameters.dat) failed: Unexpected EOF dovecot: Error: child 19036 (login) returned error 89 Thankfully, deleting the ssl-parameters.dat file (/var/run/dovecot/memoryhole.net/login/ssl-parameters.dat) and restarting dovecot fixed the problem, but it seems odd to me that dovecot expects /usr/local/var/lib/dovecot to exist (because, of course, it doesn't). I'm not defining that directory in the config file anywhere. Does anyone have any idea what's going on? ~Kyle -- I'm sick of following my dreams. I'm just going to ask them where they're going and hook up with them later. -- Mitch Hedberg

[Dovecot] fs quota plugin and NFS

Hi, I'm trying to use the Dovecot v1 fs quota plugin. The server uses NFS mounted volumes for INBOX and other maildir folders. The /usr/bin/quota command is working seamlessly but I get errors with the quota plugin, which gives the following logs: Apr 19 17:46:15 rouge dovecot: IMAP(xyxyxyx): quotactl(Q_GETQUOTA, nfs.xxx.yyy.org:/home) failed: No such file or directory Apr 19 17:46:18 rouge dovecot: IMAP(yxyxyxy): quotactl(Q_GETQUOTA, nfs.xxx.yyy.org:/home) failed: No such file or directory Is there a way to get it work ? Thanks, -- Nico Il faut s'entraider, c'est la loi de nature. -+- Jean de La Fontaine (1621-1695), L'Âne et le Chien (Fables VIII.17) -+-

[Dovecot] mailquota in ldap attribute 'mailQuota'
by Shahmat Dahlan 13 May '07

13 May '07

I've tried having the ldap quota in an ldap attribute, which still doesn't work. /etc/dovecot.conf protocols = imap pop3 mail_location = maildir:/data/mail/%u/Maildir protocol imap { mail_plugins = quota imapquota } plugin { quota = maildir:ignore=Trash } the rest are defaults added an attribute 'mailQuota' with value '10240' kbytes or 10Mbytes as for /etc/dovecot-ldap.conf user_attrs = mail,homeDirectory=home,uidNumber=uid,gidNumber=gid,quotaStorage=mailQuota Would appreciate if anyone could assist on this. I'd prefer to use the above than setting the mail quota manually: quota = maildir:storage=10240:ignore=Trash We are actually in the planning stage of migrating all of current our mailboxes from Netscape to Dovecot, instead of upgrading it to those new Sun.

[Dovecot] Migrating to Maildir -> path
by Wouter de Jong 13 May '07

13 May '07

Hello, I'm in the process of migrating to Maildir, and I wondered what would be an acceptable path. I want to do virtual-accounts only, so $HOME/Maildir/ is not an option. I was thinking of /some/path/username(a)domain.tld/Maildir/ and later perhaps /some/path/(firstletter)/username(a)domain.tld/Maildir/ but perhaps Maildir/ is a bit too redundant here.... Anyone who could advice ? Many thanks, Wouter

[Dovecot] Mixing MBOX and Maildir?
by Marc Perkel 13 May '07

13 May '07

Is it possible to have some folders be mbox and some be maildir format? Why you might ask? Sometime for diagnostics I have the Exim MTA archive certain messages in MBOX format and then I want to copy them into an imao folder to look at them with Thunderbird. When I used MBOX all I had to do was copy the file into a folder and it worked. So what I'd like to do is have a folder with a special name that is MBOX and the rest be maildir. Ideally have Dovecot be smart so that if the file exists then it is assumed to be MBOX and if the directory exists then it is assumed to be maildir. Has anyone done anything like this?

[Dovecot] Time adjusting
by Robert McKenzie 13 May '07

13 May '07

Would it be possible to have an option/variable in the config file to allow for easier setting of the maximum time to sleep for rather than having it hard coded or allow for adjustment up to an amount greater than 5 as it is at present but still have an upper limit hard coded. My system is regularly out on boot up by up to 7 seconds and consequently dovecot kills itself, if I restart it is fine and keeps going without a problem until the next reboot.

[Dovecot] Writing a new mailbox access module
by Tom Alsberg 13 May '07

13 May '07

Having finished a few other projects, I'm contemplating trying to write a new mailbox module which could be useful for us here. I would appreciate any guidance. Basically, I need (or rather, could use) a module that provides a merge of two mailboxes (which are themselves accessed by other modules), cascading them, so that: * The user sees one mailbox M, which contains all the messages in the mailboxes A and B. * A and B are both already accessible by existing Dovecot mailbox access modules, but possibly by different modules (e.g. A is an mbox, B is a Maildir). * Any write operation (creation of a new message, etc.) is eventually performed on B. * As soon as a message that was in A is accessed (either for read or for write), it is transferred to B. I would use such a module to combine the spool file in /var/mail with some INBOX in the user's home directory. The incentive is the following: * Traditionally, users receive their mail in the spool, commonly in /var/spool. Mailers, like mail, elm, pine, mutt, etc. move each read message to some record mailbox (commonly ~/mbox, but with the more advanced mailers it can be configured to be some other mailbox, even a Maildir). * Users keep working this way. IMAP will not substitute the regular mail access when inside the network here. But it should be as convenient as possible to use it from the outside (e.g. at home, or from an Internet Café, or using some Webmail interface). * Mainly for administrative reasons, it is desirable that mail keeps being delivered to the spool, and not directly to the user's home directory. One of the reasons is that mail never fails to be delivered as long as there is space in the spool. When the user is out of quota on his home directory, the mail does not get rejected, and a failure only occurs when the user initiates some operation (like reading the message). Another reason is simply to be compatible with the way traditional mailers and users work. * IMAP, and IMAP clients (e.g. Thunderbird, the most common one here), on the other hand, usually do not recognize the concept of a spool. There is an INBOX, where all mail arrives, and this is where all new messages should arrive, and remain, unless they are deleted moved elsewhere. * It would of course not be desirable to just move messages automatically after the user reads them, because it would confuse users when a message suddenly disappears from a mailbox all by itself. * The best way I can think of to be consistent with both the traditional way mailers work (moving messages from spool to ~/mbox after they are read) and the way IMAP is commonly used (INBOX contains all received messages not deleted or moved, including messages that just arrived), would be using such a module as I suggested, with (using the previous terminology) e.g. M=INBOX, A=spool, and B=~/mbox. I have just skimmed again through the mailbox code (which I last looked at over a year ago, back when it was in alpha releases), not going too much into details. From past experience and current skimming, working with that code doesn't seem too straightforward, though. I can think of how to implement the logic I described on its own (i.e. as a library with a few functions), but not sure how difficult it will be to interface it with Dovecot. Is there any developer/module writer's guide somewhere that explains the mailbox access module interface? I'd appreciate some basic guidance to start with. If I get to working on it seriously, expect lots of questions from me about the code :-) Regards, -- Tom -- Tom Alsberg - hacker (being the best description fitting this space) Web page: http://www.cs.huji.ac.il/~alsbergt/ DISCLAIMER: The above message does not even necessarily represent what my fingers have typed on the keyboard, save anything further.

[Dovecot] dovecot deliver tries to setuid but why?
by Daniel 13 May '07

13 May '07

Hi! I've set up postfix(2.4.1) + dovecot(1.0-cvs) + dovecot-lda(1.0-cvs). Dovecot's deliver is running as vmail:vmail (according to postfix's master.cf). Now the problem (when receiving mail): deliver(leva): auth input: leva deliver(leva): auth input: uid=8006 deliver(leva): auth input: gid=8000 deliver(leva): auth input: home=/var/mail/virtual/leva deliver(leva): setuid(8006) failed: Operation not permitted Every virtual user has different uids, but the gid is the *same* for everyone. The gid is 8000(vmail) for everybody, and deliver runs as 8000:8000 (vmail:vmail). vmail group has write access to the users' maildirs. So why does deliver try to setuid when it has group write permission to the destination directory? Thanks! Daniel

[Dovecot] Virtual User Home Directory, and APOP Clear Text Passwords
by imacat 13 May '07

13 May '07

Dear all, Hi. This is imacat from Taiwan. I'm new to this list. I was migrating from Qpopper to Dovecot. (Qpopper copies the mailbox when POP3 logged in, which causes quota problem.) Generally Dovecot is nice. However, I have a few questions: 1. I have a few virtual users, and I'm not using IMAP. Do I still have to give them a writable home directory? I mean, they exists only for me to receive mails from fetchmail. They really have nothing but their inbox. But if I do not give them a writable home directory, I got this error in my syslog all the time: mbox: Can't create root mail directory /home/homeless/mail: Permission denied 2. I would like to use APOP in addition to SSL/TLS. Currently Dovecot saves APOP passwords as clear text. I understand this. But is it possible to have some sort of encoding, for example, Base64? Just to prevent casual reads. I have several users. I do not want to know their passwords just to add them to the APOP database. I do not want other roots to read my passwords, intended or not. Encoded passwords also have the advantage that I can use passwords that contain the colon sign ":". It would be nice if something a little harder than Base64 can be used. Thank you very much in advance. -- imacat ^_*' imacat(a)mail.imacat.idv.tw PGP Key: http://www.imacat.idv.tw/me/pgpkey.txt Tavern IMACAT's http://www.imacat.idv.tw/ Woman's Voice http://www.wov.idv.tw/ TLUG List Manager http://www.linux.org.tw/mailman/listinfo/tlug

[Dovecot] SASL using different auth database?
by Dave McGuire 13 May '07

13 May '07

Hi folks. Is it possible to configure Dovecot to authenticate against one mechanism (i.e., /etc/passwd) for POP/IMAP connections, while providing a SASL authentication socket that satisfies authentication requests against a different mechanism, say MySQL? The goal here is to allow users to have different passwords for SMTP authentication and POP/IMAP connections. I am converting an existing installation to Dovecot...this installation currently has quite a few users who are configured with SMTP authentication (Cyrus SASL/saslauthdb) using different passwords than are configured for their POP connections (via cucipop, /etc/passwd). If someone can think of any better way to accomplish this goal, I'm all ears. Thanks, -Dave -- Dave McGuire Port Charlotte, FL

[Dovecot] logging IMAP size?
by Armijn Hemel 12 May '07

12 May '07

hi all, is there a way to somehow log the size of an IMAP session with Dovecot? With POP3 there is this pop3 format string I can set in dovecot.conf, but I don't see an equivalent for IMAP. If so, are there any plans to add this functionality? thanks, armijn -- --------------------------------------------------------------------------- armijn(a)uulug.nl | http://www.uulug.nl/ | UULug: Utrecht Linux Users Group ---------------------------------------------------------------------------

[Dovecot] dbox redesign
by Timo Sirainen 12 May '07

12 May '07

I don't think anyone uses dbox currently, so the whole format could still be redesigned. So I was thinking about doing two major changes: 1. Rely on index files a lot more. The flags are already stored in index files, so there's no need to waste I/O updating them to dbox files all the time. They could still be updated (if indexes get deleted, the flags aren't all gone), but less often. 2. Require fcntl() locking. Currently dbox uses dotlocks which is slow. Cydir could be a good alternative also once index file code is made a bit more robust. Perhaps I could implement single instance attachments for cydir too.. Locking ======= The current dbox "index" file would be gone. It's pretty useless. Replace it with a whole new index file. Or perhaps it should be called "locks" file or something. The locks file would contain records: <file id> <lock timestamp> <status>. So something like: <header> 1 4645a60f 0 2 00000000 N 3 00000000 D That would mean that the first file is locked by some process, either for appending or expunging. The 2nd and 3rd files aren't locked. New messages can't be appended to 2nd file anymore. 3rd file is already deleted and this record needs to be removed when rewriting the file. Locking a dbox file for either appends or expunges is done like: 1. See if timestamp is zero - If not, see if it's older than .. let's say a day or so .. a) Yes: Continue to 2. b) No: Assume the file is locked 2. Do fcntl() byte range lock over the record line in the locks file. - If it failed, the record is locked 3. Write the timestamp. 4. Compare stat() and fstat() inodes to see if the file was rebuilt - If yes, reopen the file and goto 1 5. File is now locked. Do the append/expunge. 6. Write timestamp to zero. 7. Unlock the byte range. If a file is locked, append will try another file and expunge will mark the message as expunged instead of actually expunging it yet. Note that the locks file is read without locking. This is safe because data is never moved within the file, and it doesn't matter if the timestamp isn't read correctly always. The timestamp check is only an optimization. Actually I'm not sure if it would be better not to have the timestamp at all. Deleted records will stay in the file until the file is rebuilt. If a deleted record is noticed in the file, the process tries to lock the whole locks file. If it succeeds, it proceeds with writing the non-deleted records to a temporary file and rename()ing it over the locks file. Appending ========= 1. Find the first file in the locks file that has appendable=0 - If no such file was found, go to "create a new file" logic as described below 2. Lock the file record 3. Verify from the file's headers that this file can actually be appended to - If messages have been expunged from a dbox file, it can't be safely appended to anymore. - Other reasons include eg. configurable max. file size and daily rotations 4. Write the mail 5. Lock locks file's header 6. Get the UID from "next uid" field and update it 7. Unlock the header 8. Unlock the file record 9. Update index file Create a new file logic: 1. Create a temporary file 2. Write the messages there 3. Lock locks file's header (including fstat() / stat() rebuild check) 4. See what the latest file ID is in the file 5. rename() temp fail to msg.<latest file id+1> 6. Lock locks file for the range of the to-be-written record below 7. Write the new record to locks file 8. Go to step 6 in the original append logic Syncing / expunging =================== If locks file's header's "next uid" doesn't match the one currently in index file, the appending crashed between steps 6 and 9. Find the new message(s) and append them to index file. If the locks file is completely gone , rebuild it by going through all the msg.* files in the directory. If "expunge counter" (see below) doesn't match in locks file's header vs. index file header, go through all the msg.* files to see if a message exists in multiple files. If found, remove the duplicates. Typically neither of the above happens, so the only thing to do here is to write changes from index file to dbox files. This may mean flag changes once in a while, but most importantly expunges will always be synced. Initially figure out what files require expunging. Try to create a single lock range that includes all of them. If there are non-zero lock timestamps in that range, create multiple ranges. If a file couldn't be locked, the expunge is done by updating expunge-flag in the file. This can be done without locking (see below for flag updates). If a file was successfully locked, the expunging is done by: 1. Update "expunge offset" in file header to the offset of the first expunged message. If expunge offset is non-zero, the file is treated as non-appendable. Also when rebuilding and finding the same message from multiple files, this field is used to figure out which file should be truncated. 2. Copy the rest of the non-expunged messages to a new temporary file and add the file to locks file using the "Create a new file" logic described for appends. Instead of updating "next uid" field, update "expunge counter" field. 3. ftruncate() the old file. 4. Update "expunge counter" in index file. Sync locking ============ If there is one big "sync lock", then flags can be updated in any file with relying only on that lock. Some files may be locked, but they're locked for appends so flag updates (and other record updates as well) are safe. It would be interesting to make it work without that sync lock though, so that multiple processes could be syncing dbox at the same time. But there probably isn't much point. If the sync is locked, there's no real requirement to do the syncing at all then, it's just left to be done later. If multiple processes were syncing at the same time, the only problem would come from flag updates. Either the files would have to be locked for flag updates (with waiting locks, bad bad), or it would need to be able to handle the situation when a flag was written just when another process expunged messages from the file and truncated it. That could be done by checking (one way or another) after the flag write if a truncation had happened, and if so do the truncation again. Preventing out of sync disconnects ================================== Reading messages from dbox files requires no locking, so it's possible that while one session is reading a message another session goes and expunges the message by truncating the file. The only way to handle this situation is to disconnect the client. Also even if the message wasn't in the middle of being read, this kind of a out-of-sync could happen if a session hasn't synced itself yet (no NOOP/IDLE/etc. for a while) and tries to begin reading an expunged message. These could be avoided if the expunging process knew that there are other processes that still know about the message, so it could just mark the message as expunged instead of actually doing it. I think this could be done with yet another file that tracks what messages are expunged. The file would contain "dovecot.index.log file sequence + offset" records. Whenever message(s) are expunged, a new seq +offset is written containing the position in the log file for that transaction. All the processes accessing the mailbox would then read lock the file from eof to infinity. The lock is updated whenever mailbox is synced (and being careful not to have race conditions there). So syncing process would then try if it can write lock the file from "last real expunge" log position to end of file. If not, then using some binary search find the position how far it can be locked. If it managed to update the write lock position at least some, the messages up to that far in the transaction log can be expunged safely. One problem with this is that the file needs to be rotated once in a while so that it won't grow infinitely. This can be done only if the write lock can include the whole file (including infinity). And that can be done only if there's a single process having the mailbox open, which may never happen with shared mailboxes. I think I'll leave this feature to be implemented later. It's extra overhead that's probably rarely useful. Single instance attachments =========================== I'll change the dbox messages to have variable sized headers. The header could then contain information such as "at offset 5000 insert 11241242 bytes from file AB123427852". Fast copying ============ Would be nice if copying a message from one mailbox to another wouldn't require actually reading+writing the whole message contents. But I can't really figure out how to implement this without requiring that there is only a single dbox storage which contains the mails for all the mailboxes, and the mailboxes themselves are just Dovecot's index files containing pointers to the dbox storage. The problem with having everything in one storage is that if the index files are broken, the messages can't be placed into correct mailboxes anymore. Although one possibility would be treat mailboxes a bit similarly than keywords. So that when a message is copied to another mailbox, the message in dbox file is updated to contain information that it exists in such and such mailboxes. Hmm. Perhaps that would be good enough, yes.

[Dovecot] Problems with BEFORE searches.
by Trever L. Adams 12 May '07

12 May '07

Ok, I am trying to modify some code given to me by the author of the dspam plugin for dovecot (sorry the name eludes me). I am modifying it to handle UNSEEN differently than SEEN. Below is the python code. I am not a python programmer, but I get the basic idea. ok, uids = conn.search(None, 'BEFORE', unreadsentbefore, 'SEEN') "11-May-2007 06:18:29 -0600" is the value of unreadsentbefore. However, this doesn't match any emails even though they are all dated as 5/10 and they have all been read for several hours (the time was the current to figure out why it isn't working). Is there a problem with BEFORE and SEEN together? Is there a BEFORE bug in the system? Some of the messages are -500 and others, I am not sure. Thanks, Trever Adams

[Dovecot] read only maildir subscriptions
by Nagyon Almos 11 May '07

11 May '07

Hello, I have some (possibly very simple) questions about subscriptions: I store my old mails in /home/oldmails/ in one Maildir where I have only read-only permissions (I cannot delete, create or modify any files). Under thunderbird, I can successfully log in and read my new mails, but I cannot subscribe (?) within thunderbird to oldmails (it is grey not black as other folders). What did I do wrong? What other permissions does dovecot need? Here's the relevant part of dovecot.conf: namespace private { separator = / prefix = oldmails/ location = maildir:/home/oldmails/:CONTROL=~/Maildir/control-oldmails:INDEX=~/Maildir/index-oldmails } and when I try to subscribe to it, dovecot says: dovecot: 2007-04-30 17:58:53 Info: IMAP(xxx): Effective uid=7001, gid=1000 dovecot: 2007-04-30 17:58:53 Info: IMAP(xxx): Namespace: type=private, prefix=regi/, sep=/, inbox=no, hidden=no, subscriptions=no dovecot: 2007-04-30 17:58:53 Info: IMAP(xxx): maildir: data=/home/oldmails/:CONTROL=~/Maildir/control-oldmails:INDEX=~/Maildir/index-oldmails dovecot: 2007-04-30 17:58:53 Info: IMAP(xxx): maildir: root=/home/oldmails, index=~/Maildir/index-oldmails, control=~/Maildir/control-oldmails, inbox= Thanks for any help in advance.

[Dovecot] Dovecot not handling r/o mailboxes completely, and problem with ACL as a workaround
by Adam McDougall 11 May '07

11 May '07

First of all, I think dovecot is really fantastic and I have thanks for all the hard work. I think it will be the best fit for my ~5000 users when I have it setup completely. We normally have approx 500 concurrent IMAP connections during the day. I am trying to convert from courier-imap to dovecot, but I have an issue with public namespace folders that are not writable by certain users. Please let me know if I need to provide more information or how I can help solve this issue. In courier-imap, we were able to take advantage of the maildir structure and standard unix users/groups to allow 'decsstaff' members to have full write access while 'decsall' members only have r/o unless also a member of 'decsstaff': -rw-rw-r-- 1 postlocal decsstaff 37597 May 5 23:37 /egr/mail/shared/decs/.support.In/cur/1178422658.M533373P54269.ice drwxrwxr-x 2 postlocal decsstaff 24576 May 5 23:37 /egr/mail/shared/decs/.support.In/cur drwxrws--- 6 postlocal decsall 4096 Apr 22 18:08 /egr/mail/shared/decs/.support.In drwxrwsr-x 34 postlocal wheel 4096 May 1 07:23 /egr/mail/shared/decs In short, upper directories are used to limit world access to just one group 'decsall', and once inside, r/o world access could be used as an anonymous substitution for 'decsall' and the group permissions would allow writing by 'decsstaff'. I don't know how courier stores and checks mail directory permissions, but it was aware when a user would not be able to delete or change messages and would return a READ-ONLY imap error when an attempt to change a message occurred (courier returns this in the IMAP response to update mail flags to reflect that the client wants to move to delete a mail). I understand that imap clients will usually only set status as read or deleted first and only try to delete an email for real on expunge, but it seems dovecot does not try to detect if a message is modifyable before it is too late for the user to find out. What happens is a user appears to be able to mark messages read, move them to another folder, or delete them (another way of moving to another folder eg. Trash). The user is clueless that the changes will not occur, and only finds out later when they reload the folder to find the messages back, or tries to expunge and get an unhelpful 'internal error' from dovecot (I can help trace this situation if it helps, but I think that stage should not be reached if things were working right). My configuration has the public folder control and indexes inside a user's home directory, so it will always be possible for dovecot to record message status changes, however I do not think dovecot should update the control and indexes to reflect an IMAP operation that is not allowed to complete due to restricted permissions on the actual email file. I suppose dovecot would have to check the permissions on mail message files. As a workaround, I wondered if I could apply dovecot ACLs to the public folders to reinforce my intentions of only allowing readonly access to certain users. If ACLs worked, I could even use it as a viable alternative to the unix permissions on the maildir contents and avoid using more unix groups than necessary. For most of our shared mailboxes, there will only be a few persons with write access, and up to a dozen people with read access, so even if I have to list every user seperately I could. However, I have not been able to get ACLs to do anything useful for me, and I hesitate to use the feature to work around might be a configuration error or bug. It is also more convenient for my migration procedure if I do not have to modify file permissions or structure during downtime to switch to dovecot. I am still not sure how dovecot ACLs affect the actual permissons of dovecot processes. I have mostly tried placing a dovecot-acl file in the maildir directory (alongside cur, tmp, new) and dovecot seems to be reading it according to the log, however I am not getting expected results from the ACLs. If the unix permissions allow a client to enter 'cur' and read mails, the mail client thinks it can delete or move them (until expunge) no matter even if I put acl entries with only 'r' permission. ACL questions (which might help others understand better as well): Is a 'user=foo rl' entry supposed to remove any possible write permissions in a maildir covered by such an ACL for user foo? If not, shouldn't it at least enforce restrictions on the available mail metadata which is more likely to be writable by the user? Is it even possible for an ACL to grant additional permissions above what is granted to a user by standard unix permissions? Does an empty ACL equate to the exact permissions granted by unix, and should an admin try to design an ACL to modify as little as possible, or should the admin try to use enough acl entries to form a complete description of the desired resulting permissions? I get the impression that broad ACLs should be listed first, and more specific ACLS listed below can add or remove ACL permissions applied earlier in the file as a 'last match' case. Should the acl plugin be able to print a summary of the resulting permissions in the log (with mail_debug=yes) when accessing a folder with an ACL? A snip from logs, I generated alot today and I'm not sure which portions would be most useful so I'll start with this: May 6 15:20:08 gribble dovecot: IMAP(mcdouga9): acl: initializing backend with data: vfile:/usr/local/etc/dovecot-acls May 6 15:20:08 gribble dovecot: IMAP(mcdouga9): acl: acl username = mcdouga9 May 6 15:20:08 gribble dovecot: IMAP(mcdouga9): acl: owner username = May 6 15:20:08 gribble dovecot: IMAP(mcdouga9): acl vfile: Global ACL directory: /usr/local/etc/dovecot-acls May 6 15:20:08 gribble dovecot: IMAP(mcdouga9): Namespace: type=public, prefix=#shared/decs/, sep=/, inbox=no, hidden=no, subscriptions=no May 6 15:20:08 gribble dovecot: IMAP(mcdouga9): maildir: data=/egr/mail/shared-dovecot2/decs:CONTROL=/home/mcdouga9/Maildir/dovecot/public/control/decs:INDEX=/home/mcdouga9/Maildir/dovecot/public/indexes/decs May 6 15:20:08 gribble dovecot: IMAP(mcdouga9): maildir: root=/egr/mail/shared-dovecot2/decs, index=/home/mcdouga9/Maildir/dovecot/public/indexes/decs, control=/home/mcdouga9/Maildir/dovecot/public/control/decs, inbox= May 6 15:20:08 gribble dovecot: IMAP(mcdouga9): opendir(/egr/mail/shared-dovecot2/decs/tmp) failed: Permission denied # dovecot --version 1.0.0 The reason I have so many public spaces below, is to match the existing directory structure we setup for courier, and also to help us keep the directory listing more tidy since otherwise we would end up with many folders all under one directory.

Hi, Is there any way I can monitor or log the data that is being received/sent on the dovecot-auth socket? I'm trying to debug some authentication stuff, and monitoring the conversation would be very useful. Thanks! Koen

[Dovecot] No authentication sockets found
by Stewart Dean 11 May '07

11 May '07

Thunderbird (2.0) is all of a sudden checking mail server capabilities and keep posting a popup saying: "Mail Server imap.bard.edu is not an IMAP4 mail server". To the best of my knowledge, neither Tbird nor DC have been updated, though the DC imap host was rebooted today 3 hours ago. Any info on what this is about? DC is currently serving out of a special port and in evaluation list....I can't imagine that this message would please the user community! Killing and restarting dovecot appears to have at least temporarily stopped this behavior. Also and perhaps related, I am seeing a syslog message: imap-login: No authentication sockets found child xxxxxx (login) returned error 89 using SSL encrypted IMAP service Background: DC 1.0, invoked from /etc/rc.local during boot. After stopping and restarting DC, things seem to work again. As per an old problem, I checked /var/run/dovecot, but it was empty with plenty of space. FWIW, the owner/group for login dir (/var/run/dovecot) is dovecot:dovecot, perm 755, while /var/run/dovecot/login is root:dovecot, 750.

[Dovecot] locking questions
by Stewart Dean 11 May '07

11 May '07

I have Dovecot 1.0 in trial use by the IT staff, and have some locking questions Background, the mail server runs procmail, sendmail and NFS exports the user homedir and mailbox to a) a login shell host and b) a mailing list services host. It runs UWIMAP on the usual ports and dovecot on a arbitrary port number. Because of concern with NFS and file access contention. I have the following dovecot.conf file access parms set: a) mbox_dirty_syncs = no b) mbox_lazy_writes = no 1) I am seeing these errmsgs. Are they anything I should be concerned about, or are they just the inevitable result of lock contention for mailboxes and folders by procmail, imap/dovecot and NFS? > In syslog, I am seeing this: > > Apr 23 18:46:34 mercury mail:err|error dovecot: IMAP(sdean): stat(/var/spool/mail/sdean.lock) failed: No such file or directory > Apr 23 18:46:34 mercury mail:err|error dovecot: IMAP(sdean): file_lock_dotlock() failed with mbox file /var/spool/mail/sdean: No such file or directory > > While in maillog: > > Apr 23 18:46:34 mercury mail:err|error dovecot: IMAP(sdean): stat(/var/spool/mail/sdean.lock) failed: No such file or directory > Apr 23 18:46:34 mercury mail:err|error dovecot: IMAP(sdean): file_lock_dotlock() failed with mbox file /var/spool/mail/sdean: No such file or directory 2) I earlier asked, but don't think I got an answer to this question: > Everybody wants to lock differently > 1) procmail (delivering for sendmail), which seems to want to use > dotlocking, fcntl and lockf locking; for whatever reasons, the compile > time tests seem to disallow flock. > 2) UWIMAP which according to wiki.dovecot.org/Migration/UW uses: > mbox_read_locks = flock > mbox_write_locks = dotlock flock > 3) I want to run dovecot in the same environment as I switch over, for > which the locking strategy is supposed to be (according to > http://wiki.dovecot.org/MboxLocking) > mbox_read_locks = fcntl > mbox_write_locks = dotlock fcntl > > Since that same page in the wiki says.

How long before that happens? Is the interval configurable? Thanks to all. A brother sysadmin was stunned by performance gained in Dovecot. He has to keep postmaster messages for a period and filters them into a separate folder...over a long weekend this folder could get to 1500 messages and 150MB...with UWIMAP he could only delete approx 800 at a time and then had to wait 5-10 minutes for it to process. With dc, he marked off the whole folder and it was gone in seconds. -- ==== Stewart Dean, Unix System Admin, Henderson Computer Resources Center of Bard College, Annandale-on-Hudson, New York 12504 sdean(a)bard.edu voice: 845-758-7475, fax: 845-758-7035

[Dovecot] Dovecot and Outlook - IMAP Timeout error
by Phillip T. George 11 May '07

11 May '07

Hey guys, I'm having a problem with Dovecot and Outlook. I'm testing with Outlook XP (2002), but the problem occurs with Outlook 2003 as well. I'm using Dovecot 1.0.rc28. The specific error generated (for IMAP) is: "A connection to the server could not be established. <servername> is now in offline mode." In the details: "There may be a server or network problems or your timeout interval may be too short. Protocol: IMAP Server: <servername> Port: 143" It is set up with a POP3 account and an IMAP account within Outlook -- using the same physical email account. The IMAP portion is only used for spam / ham submission, while the POP3 is used for downloading the actual email. The account on the server being used is named "me2.pg.east.eacsd.com" I have a single IMAP account set up in Thunderbird, which is using the account name "me.pg.east.eacsd.com". All mail that is received at "me.pg.east.eacsd.com" is forwarded to "me2.pg.east.eacsd.com" to generate some traffic. Here is the snippet of the mail log which involves me2.pg.east.eacsd.com ( | grep me2.pg.east.eacsd.com | grep -i imap): Apr 25 02:40:11 east dovecot: imap-login: Login: user=<me2.pg.east.eacsd.com>, method=PLAIN, rip=68.14.165.23, lip=64.22.71.38 Apr 25 02:40:13 east dovecot: IMAP(me2.pg.east.eacsd.com): Disconnected in IDLE Apr 25 02:41:10 east dovecot: IMAP(me2.pg.east.eacsd.com): Disconnected: Logged out Apr 25 02:45:41 east dovecot: imap-login: Login: user=<me2.pg.east.eacsd.com>, method=PLAIN, rip=68.14.165.23, lip=64.22.71.38 Apr 25 02:45:41 east dovecot: imap-login: Login: user=<me2.pg.east.eacsd.com>, method=PLAIN, rip=68.14.165.23, lip=64.22.71.38 Apr 25 02:46:18 east dovecot: IMAP(me2.pg.east.eacsd.com): Disconnected Apr 25 02:46:18 east dovecot: IMAP(me2.pg.east.eacsd.com): Disconnected Apr 25 02:50:49 east dovecot: imap-login: Login: user=<me2.pg.east.eacsd.com>, method=PLAIN, rip=68.14.165.23, lip=64.22.71.38 Apr 25 02:50:50 east dovecot: imap-login: Login: user=<me2.pg.east.eacsd.com>, method=PLAIN, rip=68.14.165.23, lip=64.22.71.38 Apr 25 02:51:27 east dovecot: IMAP(me2.pg.east.eacsd.com): Disconnected Apr 25 02:51:27 east dovecot: IMAP(me2.pg.east.eacsd.com): Disconnected Apr 25 02:55:58 east dovecot: imap-login: Login: user=<me2.pg.east.eacsd.com>, method=PLAIN, rip=68.14.165.23, lip=64.22.71.38 Apr 25 02:55:58 east dovecot: imap-login: Login: user=<me2.pg.east.eacsd.com>, method=PLAIN, rip=68.14.165.23, lip=64.22.71.38 Apr 25 02:56:56 east dovecot: IMAP(me2.pg.east.eacsd.com): Disconnected Apr 25 02:56:56 east dovecot: IMAP(me2.pg.east.eacsd.com): Disconnected Apr 25 03:01:27 east dovecot: imap-login: Login: user=<me2.pg.east.eacsd.com>, method=PLAIN, rip=68.14.165.23, lip=64.22.71.38 Apr 25 03:01:27 east dovecot: imap-login: Login: user=<me2.pg.east.eacsd.com>, method=PLAIN, rip=68.14.165.23, lip=64.22.71.38 Apr 25 03:01:58 east dovecot: IMAP(me2.pg.east.eacsd.com): Disconnected Apr 25 03:01:58 east dovecot: IMAP(me2.pg.east.eacsd.com): Disconnected There's more before that, but I'd figured that would be enough: Apr 24 17:18:05 east dovecot: IMAP(me.pg.east.eacsd.com): Disconnected in IDLE Apr 24 17:19:34 east dovecot: IMAP(me.pg.east.eacsd.com): Disconnected in IDLE Apr 24 17:19:42 east dovecot: IMAP(me.pg.east.eacsd.com): Disconnected in IDLE Apr 24 17:20:27 east dovecot: IMAP(me.pg.east.eacsd.com): Disconnected in IDLE Apr 24 17:20:42 east dovecot: imap-login: Login: user=<me.pg.east.eacsd.com>, method=PLAIN, rip=68.14.165.23, lip=64.22.71.38, TLS Apr 24 17:43:18 east dovecot: imap-login: Login: user=<me.pg.east.eacsd.com>, method=PLAIN, rip=68.14.165.23, lip=64.22.71.38, TLS As you can see from the logs, Thunderbird didn't have a problem, which eliminates the possibility of a bad net connection (I'd assume...but I could be wrong). The problem occurred at 3AM. Some people during the day can get it every hour or so. I was able to get it to occur twice (the first time is not shown in these logs). My questions. . . 1. Is there any way to fix this Outlook problem? I have all of the outlook workarounds enabled (along with some for Netscape): imap_client_workarounds = delay-newmail outlook-idle netscape-eoh pop3_client_workarounds = outlook-no-nuls oe-ns-eoh 2. Should Outlook really be connecting and disconnecting that often? 3. Could the problem be occurring because of POP3 and IMAP being used by the same account, and the quick downloading of email via POP3 is eliminating the email for IMAP, thereby causing inactivity in IMAP? Is there a workaround or a known Outlook settings to fix this? Thanks, Phillip

[Dovecot] Troubleshooting - another suggestion...
by Charles Marcus 11 May '07

11 May '07

Hi Timo, I'm the one who suggested the '-n' option to capture the actual config settings that the running dovecot process was using (ala postfix), and you implemented it very quickly - so thanks for that! Now, I'd like to suggest an enhancement... Many people still do not provide basic things like dovecot version, and there are secondary config files like dovecot-ldap, whose settings are not included in the dovecot -n output. How difficult would it be to add these to the output so that the output would include the running dovecot version, as well as any extra config settings from any other files that are loaded when dovecot starts? It would sure make it easier, both for us troubleshooting on our own, and when asking for help on the list. Many thanks, and terrific job on 1.0! Now all dovecot lacks is full support for IMAP ACLs/shared folders, and support for single-instance storage, and it will have no real competition... -- Best regards, Charles

[Dovecot] maildir file name flags out of order?
by Aaron Solochek 11 May '07

11 May '07

I was trying to figure out why my false-positive spam messages were being tagged as "personal" by thunderbird, and I noticed a possible problem. According to DJB: http://cr.yp.to/proto/maildir.html > New flags may be defined later. Flags must be stored in ASCII order: e.g., "2,FRS". Looking at my maildir, I am seeing flags out of order, such as "2,Sdae" Shouldn't that be "2,Sade"? -Aaron

[Dovecot] Disconnected for inactivity in reading our output top=0/0
by Chris Gosley 11 May '07

11 May '07

Would someone please help with this error. Using: dovecot-1.0-2.rc28.fc6 On: Fedora Core 6 130 users all connect remotely via ADSL to server to pop their email. None of them have any problems at all with pop3. 3 users in one office, connect to the server via a NAT'd ADSL. Intermittently those three users will get a timeout error, Logfile shows: Apr 19 12:50:53 mail dovecot: auth(default): pam(vu0095,165.228.62.107): lookup service=dovecot Apr 19 12:50:53 mail dovecot: auth(default): client out: OK 1 user=vu0095 Apr 19 12:50:53 mail dovecot: auth(default): master in: REQUEST 376 12300 1 Apr 19 12:50:53 mail dovecot: auth(default): passwd(vu0095,165.228.62.107): lookup Apr 19 12:50:53 mail dovecot: auth(default): master out: USER 376 vu0095 system_user=vu0095 uid=580 gid=580 home=/home/vu0095 Apr 19 12:50:53 mail dovecot: pop3-login: Login: user=<vu0095>, method=PLAIN, rip=165.228.62.107, lip=203.36.211.209 Apr 19 12:51:49 mail dovecot: POP3(vu0095): Disconnected for inactivity in reading our output top=0/0, retr=1/0, del=0/2, size=25266 Apr 19 12:51:49 mail dovecot: POP3(vu0095): Disconnected: Logged out top=0/0, retr=2/25393, del=2/2, size=25266 99% of the time everything is perfect, it is only the three users in the one office that get this error, it is of course the head office for the customer and so they are very upset, because they get timeout errors on their email clients. They are using different versions of outlook, and outlook express, I have deactivated all nortons email scanning etc Have set the three email clients to pop mail at different times, eg. 7, 13, 17 minutes to try an avoid the possibility of simultaneous pop requests from the one IP address.

[Dovecot] read only bug?

11 May '07

Hello All, I have been still struggling with the read only maildir and I think I found something: dovecot wants to rename a file but I/it have/has no rights to do that: dovecot: 2007-05-04 21:30:14 Error: IMAP(bela): rename(/home/store/oldmails/.personal/cur/1154939281.00005.pc1.S=1879:2,S, /home/store/oldmails/.personal/new/1178307014.P8610Q0M347618.pc1) failed: Permission denied Why dovecot wants to rename it?

[Dovecot] read only maildir
by Nagyon Almos 11 May '07

11 May '07

Hello All, I try to set up a read only maildir just as in the wiki, to no avail. The extra (public) namespace shows up but I can not susbscribe to it (in thunderbird) or if I change to that "directory" (in mutt), it is empty. Is it the problem mentioned in the wiki (SharedMailboxes#Subscriptions)? If yes, how can I see/use a folder which is not subscribeable? Any help would be greatly appreciated.

[Dovecot] Error: Master request X not found
by Jordi Moles 11 May '07

11 May '07

*Hi, I've been getting the following error from time to time since i started to use dovecot more than one year ago: dovecot: May 07 19:57:24 Error: auth(default): Master request 88729.43523 not found I haven't stopped upgrading dovecot with the hope that this would be a bug and would be fixed some day, but with v1.0.0, i keep getting the same error. It just happens from time to time. Some of the users of my system complain about not being able to get to see their mails, and it is always at the time when this error is logged. Surfing through many forums, i came across with a cause that many people point to: "client closed connection at the exact same time master was logging it in" i don't know if this is what happens to my system, to be honest, i don't have a clue how to check that, i just would like to know if somebody has come up with a solution for this problem, as it seems many people are still trying to face it. thank you. ***

The Sieve plugin page of Wiki documentation (http://wiki.dovecot.org/LDA/Sieve?highlight=%28filter%29) says: "It's also not a good idea to build the plugin against self-compiled Dovecot sources, but then actually use a prebuilt binary package of Dovecot."

[Dovecot] ownership/perms on DC file objects

Back in late March I asked what ownership and permissions Dovecot's own directories and files should have; I have an obsessive nature, and wanted to get things right :(.. On April Fool's Day :), Timo responded: > Dovecot opens pretty much all the configuration etc. files as root > before dropping the privileges. So in general they could all be 0600 > owned by root In my typical turtle-crawl fashion, I got around to today, but the onership/perms came out somewhat differently, which I put down here for anyone that wants to know.........

Actually, the thing we care about is the dspam signature which is unique. So that's not a problem. The point is that you have to (a) when no files exist: move into spam: create a file <sig> with contents "spam" move out of spam: create a file <sig> with contents "notspam" (b) when <sig> file exists with contents "spam": move into spam: shouldn't happen move out of spam: unlink file (c) when <sig> file exists with contents "notspam": move into spam: unlink file move out of spam: shouldn't happen the cron job would have to iterate through all these files and call dspam depending on the contents of the file. And then it all has to be atomic. It's not really all that complex, but I was too lazy to implement it. johannes

[Dovecot] Duplicate emails with several clients
by Erick Perez 10 May '07

10 May '07

Hi, I'm using Centos 4.4 (which is redhat linux but free) that comes with dovecot-0.99.11-4.EL4. I have done a clean reinstall of the server and I have users reporting that everytime they hit "send/receive" in their outlook or outlook express software, they get the same messages, as well as the new ones, over and over again. I use postfix + dovecot and only the pop3 protocol. My dovecot.conf has the following relevant entries default_mail_env = mbox:~/mail/:INBOX=/var/mail/%u client_workarounds = oe6-fetch-no-newmail outlook-idle outlook-pop3-no-nuls mbox_locks = fcntl everything else is at default value. Also, we do not upgrade dovecot because it is not part of the upstream provider, and we do not want to break binary compatibility updates. Thanks for your guidance. -- ------------------------------------------------------------ Erick Perez Panama Sistemas Integradores de Telefonia IP y Soluciones Para Centros de Datos Panama, Republica de Panama Cel Panama. +(507) 6694-4780 ------------------------------------------------------------

[Dovecot] Managesieve: first steps
by Joseba Torre 10 May '07

10 May '07

Hi, I'm trying to get managesieve to work but, as usual, I have some issues... - First of all, the compilation process after applying the patch is a bit strange. I've used this way (i'm using centOS 4 for this pre-tests): $ tar zxvf dovecot-1.0.0.tar.gz $ cd dovecot-1.0.0 $ gzip -cd ../dovecot-1.0.rc28-MANAGESIEVE-v4.diff.gz | patch -p1 $ autoreconf (This ends with an error about missing ./ylwrap) $ automake --add-missing (This copies ylwrap to ., but fails if executed before autoreconf) $ autoreconf $ ./configure && make && sudo make install but I'm quite sure that should exist a better way... - After this, adding protocols = imap imaps pop3 pop3s managesieve and protocol managesieve { listen = *:2000 login_executable = /usr/local/libexec/dovecot/managesieve-login mail_executable = /usr/local/libexec/dovecot/managesieve } to dovecot.conf, everything seems to work fine (pop3 and imap work as usual, and I can connect to the managesieve port), but dovecot -n gives no output. (If I put out managesieve from the protocols, dovecot -n gives the normal output again). (This output is appended at the end) - Finally, I'm using Plain as the authentication mechanism, and I've been unable to connect using kmail or the sieve extension for thunderbird. As I'm not sure if any of these really work, I'll setup horde for further testing. Is there anything that I should be aware of? dovecot -n output: # /usr/local/etc/dovecot.conf syslog_facility: local1 protocols: imap imaps pop3 pop3s listen(default): *:143 listen(imap): *:143 listen(pop3): *:110 ssl_listen(default): *:993 ssl_listen(imap): *:993 ssl_listen(pop3): *:995 ssl_cert_file: /usr/share/ssl/certs/dovecot-beta.pem ssl_key_file: /usr/share/ssl/certs/dovecot-beta.pem login_dir: /usr/local/var/run/dovecot/login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(pop3): /usr/local/libexec/dovecot/pop3-login mail_location: maildir:~/Maildir:INDEX=/var/dovecot/%u:CONTROL=/var/dovecot/%u mmap_disable: yes mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(pop3): /usr/local/libexec/dovecot/pop3 mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): quota mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/lib/dovecot/pop3 pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %v.%u auth default: master_user_separator: * passdb: driver: passwd-file args: /usr/local/etc/dovecot-master.conf master: yes passdb: driver: pam args: blocking=yes userdb: driver: passwd args: blocking=yes socket: type: listen client: master: path: /var/run/dovecot/auth-master plugin: quota: fs Thanks. -- Joseba Torre.

[Dovecot] Dovecot and horde issues
by John H. Bennett III 10 May '07

10 May '07

Hello, First time poster to this list, please be kind. I am having difficulties trying to get the current stable version of horde's imp webmail to work correctly using dovecot 1.0rc15. I am using a pre-release version of SME Server 8 which runs on top of CentOS 5. I have also tried using the 1.0 release of dovecot as well. What is happenning is that when I login to imp, I don't see any folders. I can create folders in imp which do get created in my Maildir directory, but I can't see them. If I revert back to dovecot-0.99.14-1.2, then I am able to see my folders. I have been looking in the wiki at the steps needed to upgrade from 0.99 to 1.0 and I thought everything had been taken care of, but since things aren't working, I have overlooked something. I also browsed the archives and see that others are using horde with various dovecot 1.x releases, so I know it should be possible to get it to work. My dovecot.conf currently only as the below, which works fine for 0.99: maildir_copy_with_hardlinks = no my /etc/pam.d/dovecot has: more /etc/pam.d/dovecot #%PAM-1.0 auth required pam_nologin.so auth include system-auth account include system-auth session include system-auth imp servers.php: $servers['_prompt'] = array( 'name' => 'Choose a mail server:' ); $servers['thebennetthome2.com'] = array( 'name' => 'IMAP Server', 'server' => 'localhost', 'protocol' => 'imap/notls', 'port' => '143', 'maildomain' => 'test.com', 'smtphost' => 'localhost', 'realm' => 'test.com', 'preferred' => '' ); php -v PHP 5.1.6 (cli) (built: Apr 9 2007 03:37:21) Copyright (c) 1997-2006 The PHP Group Zend Engine v2.1.0, Copyright (c) 1998-2006 Zend Technologies I do get some php errors when logging into horde, and a lot of php errors when creating folders that I can post if needed. I did post my issue to the horde list as well, but there has been no answer to date. Please let me know what other information is needed to assist me with fixing this issue. Thank you very much, John Bennett Thanks, John H. Bennett III bennettj(a)johnbennettservices.com

[Dovecot] Email client dowloads previously read messages as new during migration.
by Eric and Barbara Sammons 09 May '07

09 May '07

I am migrating from UW to dovecot and using mbox. I have been able to find mbox to maildir migration information and tools; however, I have had little luck finding any tool or information for performing such a migration where I wish to keep mbox. ( I know I should migrate to MailDir, but in the case I wish to take baby steps.) I have setup dovecot pop3 communication and I go to my email client and everything works fine with the exception that all mail I have previously read (when using UW as my POP server) is downloaded again as NEW. Is there a way to prevent this from happening without setting my client to delete mail from server? thank you!

[Dovecot] Troubleshooting enhancement request...
by Charles Marcus 09 May '07

09 May '07

Hi Timo, You were good enough to add the -n flag to the dovecot command to output the current *changed* config parameters (changed as compared to the defaults) of the running dovecot process. This makes it much easier to troubleshoot issues - thanks! Another flag that postfix has is the -d flag (postconf -d). This one outputs all of the DEFAULTS of the current running postfix process/version. I just used this today to compare what I had in my main.cf to what the defaults were - and for some reason I had uncommented a bunch of things that didn't need to be uncommented (because they were the default setting), resulting in a much larger output from the postconf -n command. I know its not a big deal, but any chance of implementing this for dovecot? This would make it easy to keep the conf file (and the -n output) clean and neat. Many, many thanks for 1.0.0! -- Best regards, Charles

[Dovecot] Trying to modify the source - fopen problems
by Phillip T. George 09 May '07

09 May '07

Hello all, I don't know if this needs to be sent to a different list or not, if so, please let me know. Anyways, I'm trying to modify the dovecot source a bit, but the problem I'm having is that whenever I use "fopen", it always returns NULL. I've tried a variety of things, even fopen("/dev/null", "w") -- because that should almost always work. I'm trying to get it to work in src/pop3-login/client-authenticate.c Any idea why this might be happening? Any suggestions as to where to put the code instead? (I'm trying to check the username against some information in a file OR pass the username to a process and have it do the work) Thanks, Phillip

[Dovecot] Inconsistent Mailbox with Eudora as POP3 client
by Amon Ott 09 May '07

09 May '07

Hello everyone, one of our customers using QUALCOMM Windows Eudora Version 7.1.0.9 as POP3 client with Dovecot 1.0.0 under Linux using Maildirs reports that on various accounts they get occasional "inconsistent mailbox" errors at quit. The same Docevot binary in the same environment on other servers works fine for several other customers and ourselves. We use Postfix 2.2 with Dovecot deliver and Sieve plugin, nothing else touches the Maildirs. I have no idea what goes wrong there, I already suspected memory corruptions. The system is low on memory and uses some swap (more memory soon), does that trigger such problems?

[Dovecot] Hot to get rid of \"DON\'T DELETE THIS MESSAGE\" messages?
by foxx＠freemail.gr 09 May '07

09 May '07

I'm using Dovecot 1.0.0 (mbox) with Postfix 2.4 on my FreeBSD box, as a pop3-only server (imap is disabled). All account mailboxes are accessed using Outlook clients. I've noticed that, whenever I'm retrieving mail with pop3, a "DON'T DELETE THIS MESSAGE" is created in mbox. Although these messages are never sent to client MUAs, I found them very annoying. BTW I don't use (or used before) UW or Pine or any other c-client, therefore I assume it's a Dovecot issue. Previously I was using Cyrus and never had such a problem. Any idea how this can be fixed?

[Dovecot] sporadic slow/non response, problems copying to sent folder
by Danno Coppock 09 May '07

09 May '07

After experiencing these symptoms through many of the release candidates, we've been at v1.0.0 now for a few weeks, and they're still there. Perhaps a config issue with my setup (mbox locks?). It's really too disrupting to continue using this way. I've included symptoms, client info, mta info, log entries and config file. What other information can I provide? Please advise. Thanks, Danno symptoms: 1. Coming back to the idle client, and clicking on a newly arrived message, often a long delay (seems like minutes, sometimes) will occur before the message loads from the server. 2. Sending messages, as often as not, the client will stall, sometimes indefinitely, on "copying message to sent folder". client: * usually not more than 2-3 clients running at any time. * Thunderbird 1.5.0.10 (on XP) * Thunderbird 1.5.0.5 (on FreeBSD 5.5) mta: * Sendmail 8.13.6/8.13.6 * $sudo sendmail -bt -d0.10 < /dev/null | grep HASFLOCK OS Defines: BSD4_4_SOCKADDR HASFCHOWN HASFCHMOD HASFLOCK === log entries May 3 21:27:09 tejas dovecot: imap-login: Login: user=<annie>, method=PLAIN, rip=71.216.71.193, lip =68.224.168.249, TLS May 3 21:28:00 tejas dovecot: IMAP(annie): Disconnected May 3 21:28:01 tejas dovecot: imap-login: Login: user=<annie>, method=PLAIN, rip=71.216.71.193, lip =68.224.168.249, TLS May 3 21:32:08 tejas dovecot: IMAP(annie): Disconnected for inactivity May 3 21:37:01 tejas dovecot: IMAP(annie): Disconnected May 3 21:37:02 tejas dovecot: imap-login: Login: user=<annie>, method=PLAIN, rip=71.216.71.193, lip =68.224.168.249, TLS May 3 21:37:55 tejas dovecot: IMAP(annie): Disconnected in IDLE May 3 21:38:18 tejas dovecot: IMAP(annie): Disconnected in IDLE May 3 21:56:02 tejas dovecot: imap-login: Login: user=<danno>, method=PLAIN, rip=71.216.71.193, lip =68.224.168.249, TLS May 3 21:56:17 tejas dovecot: IMAP(annie): Disconnected for inactivity May 3 21:58:32 tejas dovecot: IMAP(danno): Disconnected May 3 22:02:31 tejas dovecot: imap-login: Login: user=<danno>, method=PLAIN, rip=71.216.71.193, lip =68.224.168.249, TLS May 3 22:03:14 tejas dovecot: imap-login: Login: user=<danno>, method=PLAIN, rip=71.216.71.193, lip =68.224.168.249, TLS May 3 22:14:10 tejas dovecot: IMAP(annie): Disconnected May 3 22:14:38 tejas dovecot: IMAP(danno): Disconnected in IDLE May 3 22:16:24 tejas dovecot: imap-login: Login: user=<danno>, method=PLAIN, rip=71.216.71.193, lip =68.224.168.249, TLS May 3 22:16:33 tejas dovecot: imap-login: Login: user=<annie>, method=PLAIN, rip=71.216.71.193, lip =68.224.168.249, TLS May 3 22:16:44 tejas dovecot: imap-login: Login: user=<annie>, method=PLAIN, rip=71.216.71.193, lip =68.224.168.249, TLS May 3 22:18:36 tejas dovecot: imap-login: Login: user=<annie>, method=PLAIN, rip=71.216.71.193, lip =68.224.168.249, TLS May 3 22:19:16 tejas dovecot: IMAP(danno): Disconnected May 3 22:19:17 tejas dovecot: imap-login: Login: user=<danno>, method=PLAIN, rip=71.216.71.193, lip =68.224.168.249, TLS ===== config $grep -E -v '^ *(#|$)' dovecot.conf protocols = imaps login_process_size = 64 default_mail_env = mbox:~/mail/:INBOX=/var/mail/%u mail_extra_groups = mail verbose_proctitle = yes first_valid_uid = 100 first_valid_gid = 0 mbox_read_locks = flock mbox_write_locks = flock protocol imap { imap_client_workarounds = delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep } protocol pop3 { pop3_uidl_format = %08Xu%08Xv pop3_client_workarounds = outlook-no-nuls oe-ns-eoh } protocol lda { postmaster_address = postmaster(a)example.com sendmail_path = /usr/sbin/sendmail } auth default { mechanisms = plain passdb pam { } userdb passwd { } user = root } dict { } plugin { }

[Dovecot] .imap files
by L. Scott Loftin 09 May '07

09 May '07

Dovecot version: 1.0.rc7 OS: Red Hat Fedora Core 6 CPU: x86 Filesystem: Linux I have recently upgraded from Fedora Core 4 to Fedora Core 6 (the FC6 was a clean install, not an upgrade). Prior to the upgrade, I used Dovecot to handle IMAP email that talked to Outlook clients. After the FC6 install and copying the .imap* files to the newly recreated user accounts, Outlook is not seeing the old email. Dovecot is creating new dovecot.* files to hold new email, not looking in the existing .imap.* files. Is there a way to either convert the .imap* files into the new dovecot.* files or any way to recover the email that anyone knows about? Thanks! Scott

[Dovecot] Switching from mailbox to maildir.. duplicates!
by Lars Johansen 09 May '07

09 May '07

Hi We have been running a dovecot server for some time.. users connect with pop. Now this server is going to be substituted with a new one.. before we used mbox, but now we will move to maildir! I have done some testing transfering the mail with the mb2md script, the conversion works correctly, but users gets duplicates since they selected "keep mail on server" I have googled for the problem, and set pop3_reuse_xuidl=yes and pop3_uidl_format = %08Xu%08Xv is the same on both servers.. but no luck. My first tought was to script in an X-UIDL header for each mail that was converted.. but that wont work since the mail already downloaded by the client didnt contain that header.. is there anyone that has some experience with this, or knows if its possible? Many Greetings, Lars Johansen

[Dovecot] Strange Mail Problem
by Jason Baker 09 May '07

09 May '07

I submitted this question to the Postfix maillist and they suggested that I post to this one. Here's my issue: I have a Postifx email system running on a CentOS 4 box, with Dovecot pop3 and imap. Last week, one of my users reported to me that about a dozen emails suddenly showed up in his in box (as unread messages), but none of them were addressed to him. Under further investigation, they turned out to be from another user's inbox. The messages were all over a month old. How could mail simply show up in one inbox from another user's? We're using Mozilla Thunderbird 1.5. Anyone else run into issues like this? -- *Jason Baker */IT Coordinator/ *Glastender Inc.* 5400 North Michigan Road Saginaw, Michigan 48604 USA 800.748.0423 Phone: 989.752.4275 ext. 228 Fax: 989.752.4444 www.glastender.com <http://www.glastender.com> -----BEGIN GEEK CODE BLOCK----- Version: 3.1 GIT$ d- s: a C++$ LU+++$ P+ L++>L++++ !E--- W+++ N o?

[Dovecot] File Changes and IDLE
by Andy Shellam 09 May '07

09 May '07

Hi Timo and all, I used to use Dovecot back in the 0.99 days a couple of years ago, had since moved to Courier IMAP, but with the release of Dovecot 1.0.0, I'm looking at moving back! One thing I currently have set up and working with Courier is the use of the enhanced IDLE mode, whereby Courier uses FAM (File Alteration Monitor) to monitor changes in the INBOX, and sends the details to the client as soon as a new mail arrives. Is this something that Dovecot supports? If possible, I'd prefer not to use FAM, as it crashes at random intervals and I have to keep restarting it. When I configured Dovecot, it said "File change notification method ..... : none". Does this mean FreeBSD doesn't support any method of notifying of file changes? Is there any way I can install, or re-configure the kernel, to include this support? Thanks, Andy

[Dovecot] auth(default): Error sending status request (Operation not permitted)
by Keith Bjorndahl 09 May '07

09 May '07

After upgrading to dovecot-1.0.0 from dovecot-0.99.14, I've started getting the following errors: auth(default): Error sending status request (Operation not permitted) but yet everything _seems_ to be functioning okay ... so far. This is a FC4 system, SELinux is re-configured and still generates errors with SELinux disabled. Ideas?

[Dovecot] INBOX inaccessible
by Sophie Nicoud 09 May '07

Hi, One of my users can't read message of his Inbox, he can view subject of message with Thunderbird or Squirrelmail and IMAP but when he click on a message in order to read it he has thess messages with Thunderbird : The current command did not succeed. Invalidmessageset: 1181461470:-1181461446. ou 1181461444:* ou 1181461444:-1181461445 with Squirrelmail : SquirrelMail: ERREUR ERREUR: Le serveur IMAP n'a pas trouvé le message requis. La cause probable est que votre liste de messages n'est pas à jour et le message a été déplacé ou supprimé (éventuellement par un autre programme qui utilise la même boîte aux lettres). traduction : IMAP server doesn't find the message Your message list isnt up to day or has been delated or moved.... With the mail -f command I can read messages and with POP3 protocol and Thunderbird also. Install : dovecot-0.99.11-4.EL4 :-( What can I do ? Thanks Sophie

[Dovecot] Password Problems
by Don O'Neil 09 May '07

09 May '07

I have a user that has a password that has {} in it (left and right curly brackets). Under earlier versions of dovecot (less than v1) there weren't any problems with it. Now that we've upgraded to v1, his password no longer work. The short term solution is for him to change his password, which he has. Has anyone else seen this same problem? It seems to pop up more when using webmail apps such as Squirrelmail or Uebiumaiu. Thanks!

[Dovecot] Moving new email from the mail spool to the inbox
by Adrian Barker 09 May '07

09 May '07

We are considering switching from the Washington UW IMAP server to Dovecot for performance reasons, but we make use of the feature in the UW server that automatically moves new email from the mail spool to the IMAP INBOX. Has anyone implemented this in Dovecot, or considered implementing it ? We have a large number of users, so cannot easily change the way that we deliver email. -- Adrian Barker, Information Systems University College London, Gower Street, London WC1E 6BT External phone: +44 20 7679 5140, Fax (+44) 20 7388 5406 Email: A.Barker(a)ucl.ac.uk

Re: [Dovecot] What would you tell the CIO in an "ABCs of Email" overview?
by Kenneth Porter 08 May '07

08 May '07

Perhaps the first fundamental is that Internet email isn't handled by one kind of server. It's a suite of protocols that are served by distinct processes. At minimum, you have inbound (POP3, IMAP) and outbound (SMTP) servers. You may also have a separate authentication server (LDAP) and perhaps other pieces providing calendaring, web mail (HTTP), and central storage of client configuration (ACAP). The different protocols exist not because some programmer thought it would be cool to create a new protocol, but because they serve completely different needs. For example, POP3 was designed to support lightweight disconnected clients. IMAP provides server-based storage of mail folders. LDAP provides authentication not just for mail systems but for many other applications. (I'm sure experts for each of these protocols could provide better explanations. The RFC for each probably has a motivation section that you can quote.) An important "slide" in the presentation would show the plumbing that ties all these protocols and processes together and shows how mail moves through the system. In some cases the plumbing itself is variable. For example, spam and virus processing might occur within several servers or within a client.

[Dovecot] sieve parse error

Hello everyone, I'm using Dovecot (v1.0.beta3-3ubuntu5.4 under Ubuntu) with postfix and LDA with virtual users. Everything is working fine. To filter mails I use the Dovecot Sieve feature. But I get some strange error for one simple Sieve script: ---------------------------------------------------------------------------------------------------- require "fileinto"; if header :contains ["to", "Cc", "Bcc"] ["freewrt-users(a)freewrt.org"] { fileinto "Mailinglists.FreeWRT"; stop; } elseif header :contains ["to", "Cc", "Bcc"] ["getmail(a)discworld.dnsalias.org"] { fileinto "Mailinglists.getmail"; stop; } ---------------------------------------------------------------------------------------------------- This is the error I get in mail.log: ---------------------------------------------------------------------------------------------------- May 6 15:47:08 gehirnschnecke deliver: sieve parse error for matthias(a)adminlife.net: line 8: syntax error, unexpected IF, expecting '{' ---------------------------------------------------------------------------------------------------- After studying sieve.info my sieve script should be correct. What could be wrong here? Thanks & best regards Matthias

This kind of behavior looks like a network issue. > You called it. We access the server over the Internet. How did I forget to provide that small detail? However, that's not the slowness I speak of. Perhaps a better term is long delay, like waiting on some timeout, before message loadding (in symptom 1., above). So are there parameters to tune, that will make dovecot behave nicer? I do not believe this to be connectivity outages between our clients and the server. For one, we never experienced these symptoms with UW-IMAP. I just duplicated the stall on copying to Sent folder. This is probably the more prevalent, and annoying of the two problems. facts: * There was only one active client. * The client was T'bird, v1.5.0.10, running on XP. * This particular test had a 3Mb attachment. * The mail was delivered immediately to the single, remote recipient (after a ~20 seconds of 3Mb upload). * The "Copying to Sent Folder" dialog stayed up for (no exaggeration) 15-minutes, and then completed; the message is in the Sent folder now. suspicion, from months of experiencing the behavior: * Attachments are usually involved. How does the config look? Are the mbox lock settings appropriate? I was somewhat shooting in the dark there. * Sendmail 8.13.6/8.13.6 * $sudo sendmail -bt -d0.10 < /dev/null | grep HASFLOCK OS Defines: BSD4_4_SOCKADDR HASFCHOWN HASFCHMOD HASFLOCK mbox_read_locks = flock mbox_write_locks = flock What else can I provide? netstats? tcpdumps? Are there logs/debugging appropriate to enable? Thanks for any ideas, Danno

[Dovecot] Converting Courier mailboxes to Dovecot
by Andy Shellam 05 May '07

05 May '07

Hi, I have around 100 mailboxes (maildirs) to convert from Courier IMAP (4.1.3) to Dovecot. (From a recent backup) I've tested a few mailboxes on Dovecot 1.0.0, and while the client doesn't notice any difference (at least in Thunderbird) I'm hoping to get rid of the old Courier folders and convert any useful information they may have into Dovecot. I've tried Timo's migration script (http://www.dovecot.org/tools/courier-dovecot-migrate.pl) but it fails at line 230 with a "no file/directory" error. At that line, it appears to be finding Courier's keywords folder (courierimapkeywords), and looking for a file called ":list". However in my mailboxes, there's no file by that name, only what looks like a set of standard IMAP filenames, most of which are empty files. If I can't salvage anything useful, is there any adverse effects to me deleting all the "courier*" files/folders from each mailbox and subfolders so when the client connects back when Dovecot's running, it creates it's own UIDs and keywords etc? Thanks Andy.

[Dovecot] Help with LDAP authentication - user / user+domain
by Venilton Junior 04 May '07

Hello Folks, I've my dovecot working well and authenticating in my ldap servers. But I'd like configure my users to authenticate in two ways. One is just submitting the username and the other one is providing user(a)domain.com . I'm moving from a cyrus-imap solution to dovecot and I've implemented it with VD domains. But nowadays I still have one domain at my servers. So to no cause to much impact to users, I'd like to provide this two ways of authentication. Here follows my dovecot-ldap.conf: hosts = localhost dn = uid=admin,ou=administrators,ou=topologymanagement,o=netscaperoot dnpass = XXXXXX auth_bind = no ldap_version = 3 base = dc=domain,dc=com deref = never scope = subtree user_attrs = mail,homeDirectory,,,,quota=quota=maildir:storage user_filter = (&(objectClass=VirtualMailAccount)(mail=%u)(accountActive=TRUE)(delete=F ALSE)) pass_attrs = mail,userPassword pass_filter = (&(objectClass=VirtualMailAccount)(mail=%u)(accountActive=TRUE)(delete=F ALSE)) default_pass_scheme = SSHA user_global_uid = 100 user_global_gid = 101 My logs: Apr 30 13:47:58 server dovecot: auth(default_with_listener): client in: AUTH 1 PLAIN service=POP3 lip=xxx.xxx.xx.xx rip=xxx.xx.xxx.xxx resp=AGpveWNlLm1hcmlhbm8AbWFrdHVi Apr 30 13:47:58 server dovecot: auth(default_with_listener): ldap(user.test,xxx.xx.xxx.xxx): pass search: base=dc=domain,dc=com scope=subtree filter=(&(objectClass=VirtualMailAccount)(mail=user.test)(accountActive= TRUE)(delete=FALSE)) fields=mail,userPassword Apr 30 13:47:58 server dovecot: auth(default_with_listener): ldap(user.test,xxx.xx.xxx.xxx): unknown user Apr 30 13:47:59 server dovecot: auth(default_with_listener): client out: FAIL 1 user=user.test Apr 30 13:48:05 server dovecot: pop3-login: Aborted login: user=<user.test>, method=PLAIN, rip=xxx.xx.xxx.xxx, lip=xxx.xxx.xx.xx If I provide user.test(a)domain.com works fine.

[Dovecot] Sieve not recognizing keywords
by Alexander Hoogerhuis 04 May '07

04 May '07

First, I've been lurking and using dovecot for a few years now and I've always liked it, great piece of software! :) I've finally decided to clean up my act here and get virutal users and get postfix (2.3), dovecot (1.0.0) and deliver to play nice, using postfixadmin. I have it 99% there, but one thing is left: When I receive mails, deliver finds my virtual home dir and then tries to compile the sieve script (converted from procmail with the script mentioned in the wiki), and then always bums out on this: sieve parse error: line 3: Unsupported features in require line and line 3 looks like this: require ["fileinto","regex","envelope","vacation"]; which should be fine? Then I googled around and found this thread from january: http://www.dovecot.org/list/dovecot/2007-January/018376.html Which made it sound like the sieve plugin 1.0.0 had a bug that got fixed in 1.0.1. I am doing all of this on Gentoo, so I decided to just redo the ebuild so that I got the dovecot 1.0.0 ebuild, but with the sieve plugin 1.0.1. Aparently I get the same error and now am at a loss here. Any pointers? -A

[Dovecot] Testing IMAP clients with Dovecot, problems with MacMail
by Stewart Dean 04 May '07

04 May '07

I've been testing my user community's IMAP clients when I try to login and then transfer a big message from the inbox into a folder in an overquota folder directory. I am using native filesystem quotaing in AIXV5.3 with UWIMAP and comparing my results with what I see with Dovecot 1.0.0. (My Dovecot built without any plugins or quota extensions) Everything matches/works except for Mac Mail under SSL with Dovecot.. Mac Mail: 1) with UWIMAP, login and mailbox load goes OK, then the illegal overquota xfer fails (as it should) with a popup reading 'Message could not be moved', with (port 993) and without (port 143) SSL 2) with Dovecot, 1) login and mailbox load goes OK to port 10143, plain listen, and the illegal xfer correctly fails as it should with a popup messge under a plain connection, but 2) When the port number is set to the Dovecot ssl_listen port and the SSL box is checked, Mac Mail doesn't bring up the inbox and folders...it acts like it can't connect. Has anyone else seen this behavior, and is there a fix? Mac Mail is also known as Mail.app. I am testing it at 1.3.11 and 2.1.1. In the July '05 archive, I found this: > It looks like Mail.app treats "non-standard" ports differently. On the > standard port (993), the "SSL" option seems to do pure SSL; but with > another > port specified, it does clean-plus-starttls (and hence fails horribly, > because > it's talking to a pure SSl service) Is there anything I can do to get MacMail to behave correctly? Or will it clear up when I shut down UWIMAP and give Dovecot the default ports. A Bronx cheer for Mac Mail........ My thanks in advance, S. Everything else I tested behaves...for anyone that's interested....... ================ Over Quota Xfer results ==================== Insecure Pine from Unix login shell: refused by both UWIMAP (cannot exceed user or group quota) and Dovecot (there's not enough disk space.) server apps. It is presumed that this will be used from within an SSH session to secure the transmission. Webmail (horde, insecure and secure) : refused by both UWIMAP (cannot exceed user or group quota) and Dovecot (there's not enough disk space.) server apps.

[Dovecot] Does dovecot do any address checking or referring back to a server?
by Wade Smart 04 May '07

04 May '07

This is a dovecot question so bear with me. I just upgraded to Ubuntu 7.04 from 6.06. I used fetchmail and postfix but not dovecot on 6.06. Fetchmail retrieved my mail and postfix put it in my maildir. I used Evolution to access the maildir directly. I setup Evolution to send mail directly as well. With this move I decided to go the extra step and get dovecot working. With some help on this form, I did that. But, I immediately started having trouble with getting my mail. Fetchmail is retrieving it but postfix keeps not processing for some reason. Im geting these error message: May 2 17:14:11 wadesmart postfix/qmgr[14778]: 6D4AD14286F3: to=<wadesmart(a)mail.wadesmart.com>, orig_to=<wade@localhost>, relay=none, delay=9331, delays=9307/25/0/0, dsn=4.4.1, status=deferred (delivery temporarily suspended: connect to smtpout.secureserver.net[64.202.165.58]: Connection timed out) The thing is - Im not sending mail at all through postfix. So my question is, I know that dovecot only serves up email to a mail client but, does it do something that I have totally missed that would some how or some way refer mail back to a server? Is there some type of address check or something going on? I know Im grasping at straws here but, I have been unable to get help from the postfix list or any list for that matter so if I can eliminate one more piece of the puzzle, all the better. Thanks.

[Dovecot] Dovecot SASL for postfix: Client host rejected: when relaying using POP mail client
by Nad 03 May '07

03 May '07

Hi everyone I have setup an ISP style mail system using postfix, dovecot, squirrelmail and mysql on ubuntu server 7.04. Everything seems to be working fine with sending recieving emails but relaying on submission service (port 587). I want to allow any client to be able to relay as long as they AUTH using dovecot SASL and are valid users regardless of what IP/host they come in from. I have a feeling that the submission service is not able to make use of dovecot sasl-auth. Here is what I have in my master.cf to enable submission service: submission inet n - - - - smtpd -o smtpd_enforce_tls=no -o smtpd_sasl_auth_enable=yes -o smtpd_client_restrictions=permit_sasl_authenticated,reject My main.cf file looks like this: queue_directory = /var/spool/postfix command_directory = /usr/sbin daemon_directory = /usr/lib/postfix mail_owner = postfix myhostname = mail.domainname.tld mydomain = domainname.tld myorigin = $myhostname inet_interfaces = $myhostname inet_protocols = ipv4 mydestination = $myhostname unknown_local_recipient_reject_code = 550 mynetworks_style = host mynetworks = aa.bb.cc.dd relay_domains = $mydestination alias_maps = hash:/etc/aliases alias_database = hash:/etc/aliases sendmail_path = /usr/sbin/sendmail newaliases_path = /usr/bin/newaliases mailq_path = /usr/bin/mailq setgid_group = postdrop transport_maps = proxy:mysql:/etc/postfix/mysql/transports.cf virtual_mailbox_domains = proxy:mysql:/etc/postfix/mysql/domains.cf virtual_mailbox_base = /srv/mail virtual_mailbox_maps = proxy:mysql:/etc/postfix/mysql/accounts.cf virtual_alias_maps = proxy:mysql:/etc/postfix/mysql/forwardings.cf, proxy:mysql:/etc/postfix/mysql/emails.cf virtual_minimum_uid = 8 virtual_uid_maps = static:8 virtual_gid_maps = static:8 dovecot_destination_recipient_limit = 1 smtpd_use_tls = no smtpd_sasl_auth_enable = yes smtpd_sasl_security_options = noanonymous broken_sasl_auth_clients = yes smtpd_sasl_type = dovecot smtpd_sasl_path = private/auth strict_rfc821_envelopes = yes smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination, reject_non_fqdn_recipient, reject_unknown_recipient_domain When I try to relay using Outlook, I see the following message in the mail.log: May 3 00:36:33 mail postfix/smtpd[10004]: connect from cable.company.client.hostname.com[12.34.56.78] May 3 00:36:33 mail postfix/smtpd[10004]: NOQUEUE: reject: RCPT from cable.company.client.hostname.com[12.34.56.78]: 554 5.7.1 <cable.company.client.hostname.com[12.34.56.78]>: Client host rejected: Access denied; from=<postfixuser(a)domainname.tld> to=<someone(a)anotherdomainname.tld> proto=ESMTP helo=<mycomputer> May 3 00:36:33 mail postfix/smtpd[10004]: disconnect from cable.company.client.hostname.com[12.34.56.78] May 3 00:36:33 mail dovecot: pop3-login: Login: user=<postfixuser(a)domainname.tld>, method=PLAIN, rip=12.34.56.78, lip=aa.bb.cc.dd May 3 00:36:33 mail dovecot: POP3(postfixuser(a)domainname.tld): Disconnected: Logged out top=0/0, retr=0/0, del=0/626, size=27305010 I have tried several options for the last 2 days but have not been able to get past in relaying email for valid-users from any/all client hosts.

[Dovecot] connecting postfix with dovecot trouble
by André Höpner 03 May '07

Hello listmembers, we have some trouble connecting postfix to dovecot. after a lot of hours the transport and delivery is working but dovecot can't get the correct user. postmap -q some.user(a)domain.com ldap:/etc/postfix/ldap-aliases.cf first returns: someuser The mailbox someuser exists and i can login with this user on imap and i can deliver directly using deliver -d but on mail delivery thrue postfix dovecot is not looking for someuser. It looks for someuser(a)host.domain.com. ---8<------ May 3 16:18:42 mail postfix/pickup[24686]: C94251DB23E: uid=0 from=<root> May 3 16:18:42 mail postfix/cleanup[24769]: C94251DB23E: message-id=<20070503161842.C94251DB23E(a)host.domain.com> May 3 16:18:42 mail postfix/qmgr[24544]: C94251DB23E: from=<root(a)host.domain.com>, size=322, nrcpt=1 (queue active) May 3 16:18:42 mail dovecot: auth(default): master in: USER 1 someuser(a)host.domain.com service=deliver May 3 16:18:42 mail dovecot: auth(default): ldap(someuser(a)host.domain.com): user search: base=dc=domain,dc=com scope=subtree filter=(&(objectClass=posixAccount)(uid=someuser(a)host.domain.com)) fields=mail,homeDirectory May 3 16:18:42 mail dovecot: auth(default): master out: USER 1 someuser(a)host.domain.com home=/var/mail/dovecot/someuser uid=100 gid=12 May 3 16:18:42 mail postfix/pipe[24772]: C94251DB23E: to=<someuser(a)host.domain.com>, orig_to=<some.user(a)domain.com>, relay=dovecot, delay=0.04, delays=0.02/0.01/0/0.02, dsn=2.0.0, status=sent (delivered via dovecot service) May 3 16:18:42 mail postfix/qmgr[24544]: C94251DB23E: removed ---8<------ It seems that postfix or dovecot appends the hostname to the mailboxname. But i cant figure out which of both. If i change the uid to someuser(a)hostname.domain.com on ldap-server anything works fine. how can i fix this? i dont know if anyone needs config files for diagnostic. if so - please tell me and i post the needed informations. best regards Andre Hoepner

[Dovecot] Any plans for storing messages on a database?
by Francisco Reyes 03 May '07

03 May '07

Redudancy and recovering from a mailstore failure is one of the concerns I am trying to address where I work. Any plans to have Dovecot store emails in a database? NAS/SAN devices which do automatic replication to a second device are extremely expensive. I also don't see any distributed filesystem which is mature and available for the OS we use (FreeBSD). I recall at one point, many months back, Timo mentioned that perhaps storing the messages in the database was a possibility for the future. Any additional thoughts on this?

[Dovecot] Migrate from mlbox to maildir, lock problem
by Sylvain Nemtua 02 May '07

02 May '07

Hi We've been using dovecot successufly for few month. Previous setup : solaris 8, postfix+LDA, mbox + index on NFS (Netapp), 2500 accounts Everything shared overs NFS, multiple servers connect to index, mbox. mail_location = mbox:/var/mail/mbox/%u:INBOX=/var/mail/%u:INDEX=/var/mail/indexes_dovecot/%u We had at first some issue with mbox locking, using lock_method = dotlock solve the issue. The problem seemed to be with fcntl. I Migrate to maildir to ease administration to use maildir quota I use mb2md-3.20.pl to migrate the mbox everything works smooth. Actual setup : solaris 8, postfix+LDA, maildir + index + control on NFS (Netapp) I change the mail_location settings to mail_location = maildir:/var/mail/maildir/%u:INDEX=/var/mail/indexes_dovecot/%u:CONTROL=/var/mail/dovecot_control/%u And now I'm facing new locking issue : Errors on user loging, users leaving mail on server downloading the same mail over and over.

[Dovecot] How to use option allow_nets?
by Bernd Kuhls 02 May '07

02 May '07

Hi, according to http://wiki.dovecot.fi/PasswordDatabase/ExtraFields/AllowNets there exists an option allow_nets to restrict IP ranges from where users are allowed to login to Dovecot. I am using Debian Etch with the official Dovecot packages: # dpkg -l | grep dovecot ii dovecot-common 1.0.rc15-2 ii dovecot-imapd 1.0.rc15-2 ii dovecot-pop3d 1.0.rc15-2 using a mostly unchanged dovecot.conf. I tried to add the line allow_nets=127.0.0.0/8,192.168.0.0/16 in the block passdb pam { which is the default enabled auth code in Debian. When starting Dovecot I get this error message: # /etc/init.d/dovecot start Starting mail server: dovecot Error: Error in configuration file /etc/dovecot/dovecot.conf line 777: Unknown setting: allow_nets According to the Dovecot changelog > 2006-02-27 18:46 Timo Sirainen <timo.sirainen(a)movial.fi> > > * src/auth/: auth-request.c, auth-request.h: Added "allow_nets" > extra field. If set, the user can log in only from within the > given networks (hope the code is correct...) the option exists since February 2006, while the Debian package was released in December 2006. What I am doing wrong? Using TCP wrappers instead seems not to be an option according to http://dovecot.org/list/dovecot/2006-April/012476.html Greetings, Bernd Kuhls

[Dovecot] Best authentication option
by Eric 02 May '07

02 May '07

Dear Dovecot experts, I have a small home server debian based, with postfix/dovecot/squirrelmail installed locally and working. Dovecot is used non-secured (no imaps) but only on the 192.168.0.100 address (address of the server on the local network). I want to use squirrelmail to read my email from outside. Squirrelmail can configured to access it in particular, either through cram-md5 or login auths. In that situation, is it better (I mean more secure) to use : 1) auth mechanim = cram-md5 or 2) auth mechanism = plain (using PAM authentication for dovecot) ? That will determine my dovecot configuration. Thank you Eric

[Dovecot] Strange directory created at dovecot launch
by Eric 02 May '07

02 May '07

I installed dovecot from scratch and compiled it from 1.0.0 source. Installed in /usr/local. Now everytime I launch dovecot it creates and uses /usr/local/var/lib/dovecot and /usr/local/var/run/dovecot directories. For the latter I found the modifications to do in dovecot.conf for using /var/run/dovecot instead, but for the former I see nothing about such directory in dovecot.conf. What happens ? How can I configure it so that dovecot uses /var/lib/dovecot instead ? Thank you Eric

[Dovecot] Migrate from dovecot to dovecot.. new server
by Lars Johansen 02 May '07

02 May '07

Hi We have been running a dovecot server for some time.. users connect with pop. Now this server is going to be substituted with a new one.. before we used mbox, but now we will move to maildir! I have done some testing transfering the mail with the mb2md script, the conversion works correctly, but users gets duplicates since they selected "keep mail on server" I have googled for the problem, and set pop3_reuse_xuidl=yes and pop3_uidl_format = %08Xu%08Xv is the same on both servers.. but no luck. My first tought was to script in an X-UIDL header for each mail that was converted.. but that wont work since the mail already downloaded by the client didnt contain that header.. is there anyone that has some experience with this, or knows if its possible? Many Greetings, Lars Johansen

[Dovecot] Courier-imap + dovecot simultaneously?

Hi everyone, I have a client I've been trying to talk into switching from courier to dovecot, but the owner of the company wants me to set up two different accounts in Thunderbird (I finally got him switched to that from outlook express), one accessing his account through courier, and one through dovecot, so he can compare the speed... Is this even possible? I've never tried it before, so before I spend a lot of time, I want to know if I'd be wasting it (my time)... Thanks, -- Best regards, Charles

[Dovecot] PAM, Active Directory, all users mapped to uid=0
by Matt Zukowski 01 May '07

01 May '07

I'm having a problem with authentication using PAM, connected on the back end to Active Directory. PAM authentication itself works fine. We can log in to the machine using AD credentials without any problems. Each user is automatically mapped to uid's in the 10000+ range. However, for some reason when the user logs in via dovecot, the user's uid and gid are showing up as 0. For example: dovecot: May 01 11:22:47 Info: auth(default): master out: USER 3 mzukowski uid=0 gid=0 home=/home/URBACON/mzukowski dovecot: May 01 11:22:47 Error: Logins with UID 0 not permitted (user mzukowski) Is there a reason why dovecot might not be resolving the uid and gid correctly? PAM itself seems to be doing this right, since when I log on to the machine as an AD user, their UID shows up correctly as 10000+.

Strangely, everything is working fine, my users are able to authenticate against LDAP; the UIDs, home directories, quotas etc are all picked up correctly. It's just the annoying auth(default) errors that keep popping up every 20 seconds or so. Thanking in advance if anyone has any ideas. Cheers.

[Dovecot] dovecot for imap
by dhottinger＠harrisonburg.k12.va.us 30 Apr '07

30 Apr '07

I have been using uw-imap on my mailserver. I tried briefly to use dovecot with the default config. It seem to work faster, but users imap folders (user accounts are in openldap) disappeared. Is there a sample config somewhere I can look at to get some idea how to configure dovecot so all the imap folders users created will appear when I make the switch? Most of my users login via Horde. Server is an FC6 box, dovecot installed via yum install. -- Dwayne Hottinger Network Administrator Harrisonburg City Public Schools

[Dovecot] Doubled subjectlines in mailfolders
by Götz Reinicke 30 Apr '07

30 Apr '07

Hi, after the upgrade from 0.99 to 1.0rc15 on our RHEL 5 Server I noticed, that some of my mailfolders do double the mails subject line in the listview of thunderbird. The mail itself isn't doubled and the second mail contains a different content from a mail that didn't show up in the list. SO it seams, that only the subject line is somehow wrong. Any ideas or tips? I haven't found anything on that googling or in the list archive; but maybe I'm searching with the wrong syntax ... Regards Götz

[Dovecot] dovecot sendmail mysql no inbox error
by jan gestre 29 Apr '07

29 Apr '07

hi guys, we are experiencing this particular problem with one of the webmail server we manage. the server is using dovecot as pop3 and imap server while sendmail is being used as mta. when this user tries to login via telnet, this is what i've got: $ telnet localhost pop3 Trying 127.0.0.1... Connected to localhost.localdomain (127.0.0.1). Escape character is '^]'. +OK dovecot ready. user user1 +OK pass password +OK Logged in. -ERR No INBOX for user. Connection closed by foreign host. when i looked at the maillog i saw this: Apr 25 20:52:32 samplemail pop3(samplemail): File isn't in mbox format: /var/mail/samplemail Apr 25 20:52:32 samplemail pop3(samplemail): File isn't in mbox format: /var/mail/samplemail Apr 25 20:52:32 samplemail pop3(samplemail): Couldn't open INBOX: Internal error occured. Refer to server log for more information. [2007-04-25 20:52:32] tried google but not much of help, they just suggested to update or replace dovecot. i already update dovecot and made some changes to default_mail_env parameter, still the same result. dovecot version is 0.99 on a fedora 4 box any idea?

[Dovecot] Shared mailbox plans
by Timo Sirainen 28 Apr '07

28 Apr '07

** Configuration ** namespace shared { prefix = user/%u/ location = maildir:/home/%u/Maildir:INDEX=~/Maildir/shared-indexes } So the only difference to how it's configured now is that %u is expanded to whatever user whose mailboxes we're accessing. ACL plugin then uses that user as the owner in the namespace's mailbox owner. Since the default ACL is to not give any access to non-owners, the mailboxes without dovecot-acl files will be invisible. If ACL plugin isn't loaded, I suppose the mailboxes can be accessed if the process has filesystem permissions to access them. ** ACL vfile speedups ** Currently it stat() the dovecot-acl file a bit too often. It doesn't do it more than once a second, but there's really no need to do it even that often. I guess it could be changed to be configurable with default being something like 5 minutes. Create a new dovecot-acl-list file which lists all the mailboxes which have dovecot-acl file with "l" right (visible in mailbox list) to any non-owner. It could be in "<timestamp> <mailbox name>" format. This allows other users to quickly get a list of mailboxes that are potentially visible to them. They still need to read the dovecot-acl file from the mailbox before knowing for sure. If the dovecot-acl-list file doesn't exist or if at any time any timestamp doesn't match dovecot-acl file's current mtime, the file is rebuilt by looking into all mailboxes' dovecot-acl files (if the reading user has write permissions to the directory, otherwise it just keeps it in memory). Whenever Dovecot modifies dovecot-acl file, it also updates the dovecot-acl-list file. This means that the file can contain stale data only if a new dovecot-acl file is created without updating dovecot-acl-list file. Even that will be fixed the next time the owner does a LIST (or select the mailbox, or anything that causes its dovecot-acl file to be stated), which causes ACL plugin to notice the desync. There exist also global ACL files. These need to be included in the dovecot-acl-list file as well. The only issue with them is that user doesn't necessarily have a mailbox even though the global ACL file exists. So these need to be marked somehow in the dovecot-acl-list file as non-existing mailboxes. Then if user creates a mailbox with such name, the mark is removed. Deleting the mailbox puts the mark back. After the visible mailbox list has been figured out once, only the dovecot-acl-list file needs to be stat()ed once in a while instead of all the mailboxes' dovecot-acl files. ** User list ** The next problem is how to quickly get a list of users whose mailboxes are visible to ourself so they can be included in mailbox list. I couldn't figure out anything new and great for this, so the options are the same as in http://dovecot.org/list/dovecot/2006- October/017082.html Although for dict backend I could make it a bit more secure. Currently dict has "private" and "shared read-write" options to store the data with. The shared users list could be done with "shared read- only". ** Virtual domains ** ACL plugin could support virtual "group=@domain" to give access to usernames ending with @domain. Or perhaps the group could support wildcards? "group=*@domain"? That way it wouldn't be required to have @ really in the username. Anyway, I think "anyone" should then be aliased to "group=*@domain". If there are multiple virtual domains and you let the users manipulate the ACLs themselves, I'd think they want anyone to mean anyone within my domain (my organization) rather than really anyone who just happens to be using the same server. I think it would also be annoying if anyone could really force their own mailboxes to be visible to a lot of people. That could be used for spamming as well.. If administrator wants to have global mailboxes that really are visible to all domains, they could be done with public namespaces (not shared). ** Quota ** This is kind of problematic. The behavior depends entirely on quota backend: - Filesystem quota of course tracks the quota based on the file's owner - Maildir++ quota counts the quota for the user whose maildir the shared mailbox exists in. This means it also requires filesystem level access to maildirsize file, otherwise the quota updating happens sometimes later when the quota is recalculated. - Dict quota.. I think it'll need a new path for each shared mailbox, which is modifiable by any user. So while your own quota would exist in private/quota/storage, the shared mailboxes' quota would exist in shared/quota/storage. This means that the dict quota needs to be able to know what mailboxes the current user has shared. It also gets a bit tricky to update the quota if mailbox is unshared. The quota could be tracked individually for each mailbox also, but I'm not sure if that's such a great idea either. Perhaps a new quota backend could be implemented to make all this easier. The mail sizes could be tracked in index file, so getting the size of a mailbox could be done simply by reading the value from the index file's header. With mailbox list indexes (in CVS HEAD) they'd all be listed in a single mailbox.list.index file, which would make summing them up really fast. This would require that users don't use private index files for shared mailboxes though. But if the users don't have shell access the shared index files are probably a good idea anyway (at least from performance point of view). ** Symlink shares ** Currently the only way to implement shared mailboxes among users is for administrator to create symlinks. This will be possible in future too with a configuration like: namespace shared { prefix = Shared/ location = maildir:~/Maildir/shared-symlinks:INDEX=~/Maildir/ shared-indexes } The "owner" ACL won't match anyone. So it'll work exactly as it does now.

[Dovecot] dovecot + ldap + quota
by aza zel 27 Apr '07

27 Apr '07

hi.... i using dovecot 1.0rc26 and i started to configure quota plugin but i think its not working fine. i configure like suggested in http://wiki.dovecot.org/Quota in dovecot.conf: protocol imap { mail_plugins = quota imap_quota } plugin { # 10 MB quota limit quota = maildir:storage=10240 } in dovecot-ldap.conf: user_attrs = homeDirectory=home,uidNumber=uid,gidNumber=gid,quotaStorage=quota if a mua send a attach near 9MB i receive a message tell me that the server don't have more space, but if i attach files of 2MB this messages are sending ok, and the cur directory of this user have 15 MB. another question: in ldap entry, the attribute quota are the attibute that A represents the quota on a mailbox, ¿so why i put 10MB as limit? uota = maildir:storage=10240 ¿this value is for all "entryes" or the quota limit is the entry quota limit? i you can see, i not understand how dovecot works with the attribute quota in ldap entry; ¿can anybody explain me this? Thanks in advance!!!

[Dovecot] Dovecot "assertion failed" errors
by Christian Friedli 27 Apr '07

27 Apr '07

Dear all, We are running Dovecot (on debian etch, Version 1.0.rc15-2) on 4 Loadbalanced servers using a NFS share for the homedirs. The loadbalancer is using persistant connections (timeout 30min). Lately, IMAP Users (mostly using Thunderbird) reported the following errors: 1. When trying to mark messages as read, nothing happened, message was still displayed as unread. 2. When moving a Directory the client loads for a long time and then hangs. Same was reported to happened when a user tried to open a mail. When checking the logs at the time users reported those errors we could always find one fo the following "assertion failed" errors: file mail-index-sync-update.c: line 730 (mail_index_sync_update_index): assertion failed: (view- >hdr.messages_count == map->hdr.messages_count) file mail-index.c: line 415 (mail_index_map_parse_keywords): assertion failed: (ext->hdr_offset < map->hdr.header_size) file mail-index.c: line 909 (mail_index_sync_from_transactions): assertion failed: (prev_seq <= max_seq && (prev_seq != max_seq || prev_offset <= max_offset)) file mail-transaction-log-view.c: line 158 (mail_transaction_log_view_set): assertion failed: (min_file_seq != max_file_seq || min_file_offset <= max_file_offset) file mail-transaction-log-view.c: line 229 (mail_transaction_log_view_set): assertion failed: (view->cur_offset <= view->cur->sync_offset) file message-body-search.c: line 393 (message_body_search_ctx): assertion failed: (input->v_offset <= part->physical_pos) I wonder if anyone has experienced similar problems and if there is a solution to this strange behaviour. ____________________________ University of Bern IT Department Central Systems Group Christian Friedli E-Mail Services Gesellschaftsstr. 6 CH-3012 Bern Switzerland Tel. +41 (0)31 631 38 38 Fax +41 (0)31 631 43 57 mailto:christian.friedli@id.unibe.ch http://www.mail.unibe.ch --

[Dovecot] sendmail + dovecot + vpopmail + virtual users, problem with pop3 uidl
by Oliver Schulze L. 27 Apr '07

27 Apr '07

Hi, I just migrated a server running qmail+vpopmail+maildir to sendmail+dovecot+maildir+vpopmail The migrating is working great thanks to the help from the list and the wiki. I'm now running the infamous problem about duplicating emails, because of pop3 UIDL mismatch. My question is: anyone knows that the pop3_uidl_format string for a vpopmail server? I'm using vpopmail auth and userdb. I noted that when manually issuing a list command to the vpopmail pop3 server, it uses a number that is in the filename for identifying the email. For example if the filename uses: .....,S=1234,... Then the UID is 1234, and 1234 appears in the list command.

[Dovecot] LSUB "" "" vs LIST "" "" (hacked Apple Mail problem)
by Eyvind Bernhardsen 27 Apr '07

27 Apr '07

The LSUB command does not act like LIST when provided with an empty mask argument. LIST responds with the hierarchy delimiter: * LIST (\Noselect) "." "" OK List completed. whereas LSUB doesn't return anything useful: OK Lsub completed. RFC 3501 doesn't specify what LSUB should do in this case, but Courier IMAP has LSUB act like LIST. The attached patch modifies imap/cmd-list.c to make Dovecot do the same. Why do I care about LSUB? I'm using a hack for Apple Mail that replaces its LIST command with LSUB (something like what's described here: http://www.macosxhints.com/article.php? story=20040407062603804), to prevent it from syncing public folders from the Exchange server at the office. The hack replaces _all_ LISTs with LSUBs, including the LIST "" "" Mail.app sends to discover the hierarchy delimiter. Since dovecot doesn't give it any information in response to LSUB "" "", Mail.app defaults to using "/" as a delimiter, which means that trying to access a subfolder only results in an "Invalid mailbox name" error. While this isn't really a bug in Dovecot, it's not inconceivable that other people than me could be affected by this problem (macosxhints.com has a substantial readership). It's also tricky to diagnose, especially since the "Invalid mailbox name" message doesn't include the invalid mailbox name, so any bug reports you get are likely to eventually be filed under "crazy [Mac] users". In fact, while Googling to figure out why Dovecot wasn't working for me, I came across at least one poster to this mailing list who had discovered that Mail.app was using "/" as a delimiter. I can't be sure, but I'm guessing that his problem was related to mine. Since the patch is tiny and doesn't hurt performance or make Dovecot do anything that contradicts the IMAP RFC, I hope you'll consider adding it to the official distribution. Eyvind Bernhardsen

[Dovecot] simple questions
by Nagyon Almos 27 Apr '07

27 Apr '07

Hello Everybody, I would like to use Dovecot on my desktop with imap but before doing the real migration I have some (very simple) questions: - Is there any way to log in with imap automatically ? That is, from localhost without any passwords. - Can Dovecot work with only readable maildirs? I want to avoid accidental e-mail loss, therefore on some maildir folder I have only read permissions. Or shall I use ACLs only? - Is there or Will there be a windows version? (In case I had to use windows.) Thanks for any help.

[Dovecot] Dovecot, Postfix and SMTP AUTH.... one more time...
by Bartosz Toczek 26 Apr '07

26 Apr '07

Hello. I've notice a problem with SMTP AUTH in postfix with dovecot. My configuration is based on Postgresql. I've created a function in postgresql which returns password and username and attached it to password_query. Query looks like this password_query = SELECT username_out as username, password_out as password FROM get_password(lower('%n'),lower('%d')); Problem is when get_password returns something like this... vmail=# SELECT username_out as username, password_out FROM get_password(lower(''),lower('')); LOG: statement: SELECT username_out as username, password_out FROM get_password(lower(''),lower('')); LOG: duration: 2.342 ms statement: SELECT username_out as username, password_out FROM get_password(lower(''),lower('')); username | password_out ----------+-------------- | (1 row) It returns 1 empty row.... When this is attached to postfix with smtp auth with such configuration # SMTP AUTH broken_sasl_auth_clients = yes smtpd_sasl_auth_enable = yes smtpd_sasl_security_options = noanonymous smtpd_sasl_authenticated_header = yes smtpd_sasl_local_domain = smtpd_sasl_type = dovecot smtpd_sasl_path = private/auth my serwer starts to be open relay... I now that it returns empty string for username and password... so where is the password checked... if I dont send password as a parameter to my function. Definition of the function looks like this: CREATE FUNCTION get_password("login" character varying, "domain" character varying, OUT username_out character varying, OUT password_out character varying) RETURNS record Can you help with that...

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, i try to use a new namespace with mbox parallel to my working maildir configuration. With this i have a few interesting effects: - - dovecot doesn't use the CONTROL statement and generate a .subscriptions file at the namespace directory. The INDEX statement is used. - - dovecot can work with subdirectories even mbox is used - - I can't work with namespaces under Thunderbird till i have a mbox file manually there. an subscription or construction of a new mbox file isn't possible :-( but this seems like one of the (handling?) bugs of Thunderbird - - Why can't i delete a Folder at an namespace?

Probably this is only a config issue. - - if i use as the first character for the prefix an # like #Archiv dovecot dosen't recognize the complete prefix statement at this namespace.

Hello list, our users are authenticated against ldap-server. anything works fine... dovecot: imap-login: Login: user=<xxx>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured but now we want to use secure passwords and not only plain over ssl. so we configured dovecot to use cram-md5 and configured the ldap-server with CRAM-MD5 passwords. as client we used thunderbird 2.0 and a webfrontend called roundcube. that does not work, because the server gives... dovecot: auth(default): ldap(xxx,127.0.0.1): Password mismatch then we tried to use DIGEST-MD5. we changed the ldap password to the created one with dovecotpw. but this doesnt work too. thunderbird requests CRAM-MD5 and not DIGEST-MD5. so the log says: dovecot: auth(default): password(xxx,127.0.0.1): Requested CRAM-MD5 scheme, but we have only DIGEST-MD5 imap-login: Aborted login: user=<xxx>, method=CRAM-MD5 after that we changed the password back to CRAM-MD5, but we mad the failure not to delete the DIGEST-MD5 value. so the users had 2 passwords set... {CRAM-MD5}e02d374fde0dc75a17a557039a3a5338c7743304777dccd376f332bee68d2cf6 {DIGEST-MD5}358aefa044c08e6c19711c8117714fb0 password is "test" in both cases. on the next try we start thunderbird it works. i dont know why and the log of dovecot says... auth(default): ldap(xxx,127.0.0.1): Multiple password values not supported imap-login: Login: user=<xxx>, method=CRAM-MD5, rip=127.0.0.1, lip=127.0.0.1, secured user was logged in using CRAM-MD5. it's not nice but it works. anyone have an idea why? because of apache-module to auth against ldap and apache doesnt support nor CRAM-MD5 or DIGEST-MD5 we have set the password third time using MD5. So every user has three same passwords with different encryptions. Not nice - but it works. But what can we do to change this. I dont like to set passwords three times. our configuration: # /etc/dovecot/dovecot.conf ssl_cert_file: /etc/ssl/ssl.pem ssl_key_file: /etc/ssl/ssl.key login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/imap-login mail_extra_groups: mail mail_location: mbox:/var/mail/dovecot/%n:INDEX=/var/mail/dovecot/indexes/%n mail_plugins: quota imap_quota auth default: mechanisms: plain login cram-md5 digest-md5 verbose: yes passdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf userdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf plugin: quota: maildir:storage=1024 ------------- # /etc/dovecot/dovecot-ldap.conf hosts = 127.0.0.1:389 dn = cn=dovecot,dc=xxx,dc=com dnpass = dovecot sasl_bind = no sasl_mech = DIGEST-MD5 tls = no auth_bind = no ldap_version = 3 base = ou=People,dc=xxx,dc=com scope = subtree user_attrs = homeDirectory=home,uidNumber=uid,gidNumber=gid user_filter = (&(objectClass=posixAccount)(uid=%u)) pass_attrs = uid=user,userPassword=password pass_filter = (&(objectClass=posixAccount)(uid=%u)) default_pass_scheme = DIGEST-MD5 ------------- best regards Andre

[Dovecot] upgrading RHEL4 to RHEL5 - dovecot 0.99 to 1.0rc15
by Götz Reinicke 25 Apr '07

25 Apr '07

Hi, now that a lot off software is updated e.g. RedHat EL and dovecot got finaly final :-) we plan to upgrade our mailserver from RHEL4 dovecot 0.99 to RHEL5 with dovecot 1.0rc15 - the rpms provided by Red Hat. I've read the upgrading Dovecot manual from here http://wiki.dovecot.org/UpgradingDovecot, but yust to get things right I'd like to ask some questions: Simply spoken, we use the basic default dovecot-config, mbox format and imaps/pop3s. So will there be any big trouble to just use the most default settings of the 1.0 config file? Or which options are compleatly different? Dose there exist a migration how to beside the dovecot upgrade from the wiki? Thanks for hints and tips!

[Dovecot] disabling pop/imap per mail address?
by Armijn Hemel 25 Apr '07

25 Apr '07

hello, first of all I want to say thanks to Timo for Dovecot 1.0. We've been running it in production at the company where I work and we're very pleased with it. Good job! One thing that we were wondering about today is if we can disable a certain protocol depending on the mailbox. So for example: user A can access via pop3s and imap, user B can only access via pop3, user C can use only imaps, and so on. thanks! armijn PS: am I assuming correctly that IMAP namespaces will make it possible to have shared IMAP folders with Dovecot? I'm still a bit of an IMAP dummy -- --------------------------------------------------------------------------- armijn(a)uulug.nl | http://www.uulug.nl/ | UULug: Utrecht Linux Users Group ---------------------------------------------------------------------------

[Dovecot] Experience with Dovecot + Sieve + Webmail?
by Steffen Kaiser 24 Apr '07

24 Apr '07

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, there were some posts into this lists regarding Webmail interfaces and Sieve. What are the experiences with them? I need a webmail frontend that is capable of IMAP, supporting dovecot's namespaces, verifying PGP and managing Sieve in conjunction with Dovecot. I found two mature products, I also saw posts about, so I'm going to ask. Some posts on this list suggest that some are using SquirrelMail/avelsieve and some Horde (IMP/Ingo). What are the experiences with them? Are they stable and are there configuration glitches (there is a thread about a bug in avelsieve, for instance). How do they interact with Dovecot in order to find the user's homedirectory to get/put the Sieve script? Maybe it's offtopic for the Wiki, but would you mind share your configuration on the Dovecot Wiki?

[Dovecot] message-of-the-day feature?
by Steven F Siirila 24 Apr '07

24 Apr '07

For lack of a better name, we are interested in a feature where one could get a notice out to all Dovecot users as quickly as possible, possibly without going through an MTA even. Given a message and a list of userids we could certainly do a mailing on the MDA server itself going through both Postfix and Dovecot LDA. However, we were wondering what other options we might have in Dovecot. For example, would it be possible to place the message into some file which Dovecot periodically checks for, and if the file exists, either present it to the user as a new message, or automatically deliver it at that time via Dovecot LDA? -- Steven F.

[Dovecot] SASL Problems
by Phillip T. George 23 Apr '07

23 Apr '07

Hello all, I seem to be having a problem with SASL. It doesn't seem to work with Outlook. Upon searching a bit, I found that I need to enable "login" for auth mechanisms. However, when I do that, (after I stop and start dovecot and postfix), and then try to use SMTP auth using Outlook, it causes postfix to crash. It works fine with Thunderbird still though. Any ideas as to what the cause might be? I'm using Dovecot 1.0.0 and Postfix 2.3.5. Thanks, Phillip

[Dovecot] Trying to explain mutt+dovecot(ssl) to myself :(
by Wilkinson, Alex 23 Apr '07

23 Apr '07

Hi all, I have recently migrated my mail from courier-imap to dovecot. In doing so, I finally configured mutt to connect to imaps (SSL). In the end I got it all working. I then sat back and thought: "I kinda don't understand the SSL/TLS part even though it works". And I hate setting stuff up and not truely understanding the mechanics of it. So I started to write about it and am stuck. Can those that _understand_ mutt+ssl have a read of what I wrote to myself and give me your $00.02 worth (corrections etc). Trying to explain mutt+ssl and getting it all wrong --------------------------------------------------- * mutt(with openssl support built in) initiates with a "SSL-Client-Hello" to SSL on port 993 i.e. mutt's capabilities (algorithms, SSL version etc). * dovecot:993 compares mutt's CipherSuites with its own. Of the CipherSuites mutt and dovecot have in common, dovecot:993 chooses the _most_ secure algorithm. * Dovecot:993 will then tell mutt what it has decided to use and assigns a Unique session ID. From now on all communication is via this ID. * Now that the CipherSuite is set between mutt and dovecot, dovecot sends its SSL certificate to mutt [/usr/local/share/dovecot/certs/dovecot.pem]. mutt then uses dovecot's corresponding public key [/usr/local/share/dovecot/private/dovecot.pem] to verify that the ceritificate is authentic. * once mutt has verified that the certificate is authentic ... and here I got unstuck.

[Dovecot] deliver failing to execute sendmail (sieve)
by Justin McAleer 21 Apr '07

21 Apr '07

I have apparently done something to mess up my test installation, as deliver's attempts to send messages now fail with the following error: deliver(user(a)example.com): execv() failed: No such file or directory In these cases, I have sieve rules trying to send messages. It had been working though, and I've tried going through all the changes I made yesterday (related to dictionary quota debugging) to find what could be wrong, but no luck so far. So, I was hoping for suggestions. Basically, deliver seems to not know where sendmail is. I have sendmail_path set in dovecot.conf (never changed that), yet when deliver tries to pull the location via deliver_set->sendmail_path, it's just returning an empty string. If I hard-code the location in smtp-client.c, it works again. Any ideas?

[Dovecot] Maillog rotates, but dovecot still writes logs into old logfile?

Tere. I use: log_path = /var/log/maillog info_log_path = /var/log/maillog And into /var/log are: maillog maillog.1 maillog.2 maillog.3 Now when log files are rotating at 04:00 (maillog > maillog.1) dovecot still keeps login into maillog.1 and not into maillog, where sendmail, etc writes logs. The only solution I did found, is adding into /etc/logrotate.d/syslog command to restart dovecot: /var/log/maillog { postrotate /usr/bin/killall -HUP syslogd /etc/rc.d/init.d/dovecot restart >/dev/null 2>&1 endscript } Any other solution? -- Mart

[Dovecot] MANAGESIEVE patch v4 for dovecot 1.0.rc28
by Stephan Bosch 19 Apr '07

19 Apr '07

Hello dovecot users, I have updated the MANAGESIEVE patch to fix the currently known small problems with the protocol implementation. It is designed for rc28, but also compiles cleanly with the current cvs branch_1_0. Change Log V4 ------------- - Added managesieve_implementation_string setting to the managesieve configuration. This can be used to customize the default "IMPLEMENTATION" capability response (as requested by John Peacock). - Denied ANONYMOUS login until proper support is implemented - Fixed problem with authenticate command regarding continued responses. In V3 only initial response would work. Problem was caused by rc2 -> rc28 upgrade. One of the clear reasons why code duplication is a very bad idea. - Fixed readlink bug as indicated by Timo: return value of readlink can also be -1. - Fixed bug in the regular file rescue code, as introduced in the previous version. Used stat instead of lstat. This caused the symlink to be rescued subsequently in the next activation, thus still overwriting the initially rescued script. This patch still includes (yet another) instance of the CMU Sieve source, as explained in one of my previous e-mails (http://dovecot.org/list/dovecot/2006-July/015016.html) It can be downloaded at: http://sinas.rename-it.nl/~sirius/dovecot-1.0.rc28-MANAGESIEVE-v4.diff.gz A design related README is located at src/managesieve after applying the patch. Have fun testing the patch. Notify me when there are problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl IRC: Freenode, #dovecot, S[r]us

[Dovecot] Duplicate E-mail Problem
by Phillip T. George 19 Apr '07

19 Apr '07

Hello all, Definitely congrats on the 1.0.0 release! Anyway, I'm having a problem, that may or may not be related to Dovecot. Specifically, duplicate (and sometimes triplicate) emails are appearing. These emails have exactly the same queue ID, so its not that they were sent multiple times. These dup emails do not show up to me ever. Postfix is being used as the SMTP, and it hands it over to procmail. I set up procmail's verbose logging feature for that user and on the duplicate emails that he receives, it shows only ONE write to a file for that specific subject of email. Tonight / this morning I'll be tracking down to see if this duplicate for sure happens in IMAP. Note: Its possible that part of the problem is he leaves two IMAP clients open at the same time (Netscape I think). I'm going to verify that with him. Any ideas? I'm NOT trying to blame Dovecot, I'm just trying to explore options. Right now its looking fairly bad for Dovecot though....I mean, what else is there after the mail is delivered to the appropriate place in the mailbox? Software versions: postfix 2.3.8 procmail 3.22 dovecot 1.0.rc28 Thanks, Phillip

[Dovecot] v1.0.0 released
by Timo Sirainen 18 Apr '07

18 Apr '07

http://dovecot.org/releases/dovecot-1.0.0.tar.gz http://dovecot.org/releases/dovecot-1.0.0.tar.gz.sig It took almost 5 years, but it's finally ready. I'm not expecting to release v1.0.1 anytime soon, unless someone's been sitting on a major bug just waiting for v1.0 to be released. :) People wanting new features should start testing the upcoming v1.1. http://dovecot.org/nightly/ contains now snapshots from CVS HEAD. It already has tons of new features. I've been using it myself for half a year, so it should be mostly stable too. I'll write a separate mail about this later.

[Dovecot] v1.1 plans - sieve?
by David Anderson 18 Apr '07

18 Apr '07

In the 1.1 plans (http://dovecot.org/list/dovecot/2007-April/021974.html) I don't see any mention of sieve... is this intentional? Sieve support is a priority for me... I'm going to have to see if I can get it via exim's support if dovecot's not going to add it in 1.1. Cheers, David
