[Dovecot] OT: Cron Output When Deleting Files
by Jeff Grossman 17 Oct '07

17 Oct '07

I have a Dovecot setup for a personal e-mail server. I have a cron job setup each evening which runs the following command to delete old messages from my Deleted Items folder. find ./ -type f -ctime +14 | xargs rm I don't know that much about bash scripting. I would like the output to tell me how many files were deleted. Can anybody share with me how can I get that done, or point in the correct direction? Thanks, Jeff

[Dovecot] Squirrelmail Problem with 1.1 Beta 3

16 Oct '07

I just installed 1.1 beta 3 and noticed a problem when sending an e-mail with Squirrelmail. When I hit send, I get the following error in my log: Oct 16 11:35:54 apple dovecot: IMAP(jeff): Disconnected: EOF while appending bytes=1851/5926 Oct 16 11:35:54 apple imapproxyd[9132]: Raw_Proxy(): IMAP server unexpectedly closed the connection on sd 9 I am also using imapproxy. I wasn't sure if that line would help also. In Squirrelmail I get a LOGOUT message when it tries to redisplay the INBOX listing. The message does get sent correctly, but it does not get copied to my Sent Items folder. I went and deleted all of the dovecot.index* files and now I don't get that error anymore, but I now get the following error. The message is now copied to the Sent Items folder.

[Dovecot] namespace prefix issue with avelsieve and dovecot v1.1beta2
by Martin Konopka 16 Oct '07

16 Oct '07

Hi, I have installed dovecot v1.1.beta2 with the sieve plugin v.1.1.2. I have configured the following namespace: namespace: type: private separator: . prefix: INBOX. location: inbox: yes hidden: no list: yes When I create a rule which should move messages into the subfolder "Junk", Dovecot's deliver seems to ignore the namespace and creates a new folder .INBOX.Junk . I think I read somewhere that in Dovecot v1.1+ deliver supports namespaces? Or have I misconfigured something? Thank you!

[Dovecot] Error: net_connect(/var/run/dovecot/auth-master) failed: Resource temporarily unavailable
by Maykel Moya 16 Oct '07

16 Oct '07

I'm using deliver (1.0.5) with Postfix (2.1.6). I made a test for a few minutes in a moderated busy server. While most mails was delivered, a lot of them failed with this error: deliver(userfoo): Oct 15 09:58:31 Error: net_connect(/var/run/dovecot/auth-master) failed: Resource temporarily unavailable Sounds to me something like not enough auth-master to answer every concurrent deliver. Any hint? Regards, maykel PD: If there any other info I could give let me know.

[Dovecot] Logging client commands (patch)
by Zach Bagnall 12 Oct '07

12 Oct '07

This might be useful to someone so I'll throw it out there. Patch against 1.0.5 adds support for two new configuration params: pop3_debug_client_commands = TOP, RETR, DELE imap_debug_client_commands = FETCH, DELETE Obviously add in whichever ones you're interested in, or none, or comment them out completely. It'll log the appropriate events: Oct 12 18:30:18 kea dovecot: IMAP(zach): Client command: FETCH The parameters are included for POP3 events. Wasn't sure quite how to do the same for IMAP and for my purposes it's not too important so imap command parameters aren't logged. Running smoothly here with a few dozen IMAP and POP3 users. Not suggesting this gets added to the codebase - I just needed it to help debug some other IMAP software and thought it might be useful. Zach.

[Dovecot] UIDL format for old UW pop3
by Oliver Hookins 11 Oct '07

11 Oct '07

Hi, we're trying to migrate from UW imap 2001a-10, which doesn't seem to use the UIDL format documented in the wiki. It seems to use a 16 character long MD5 hash of something. I've tried configuring Dovecot to do the same but the value comes out differently. The main thing that I can see is getting in the way is that the UIDL format is not documented sufficiently. There is no description of using numbers to restrict the length of the output, and no documentation of special features like X or M. Can someone shed some light on these? -- Regards, Oliver

[Dovecot] GSSAPI Cross-Realm Patch
by Zachary Kotlarek 11 Oct '07

11 Oct '07

I've written a GSSAPI cross-realm auth patch for people not lucky enough to have the __gss_userok function, though it should apply pretty cleanly with that patch in place as well. The patch is available at: http://zinux.cynicbytrade.com/svn/servers/dovecot/cross-realm.diff.bz2 It works for me on MIT-kerb, and I tested compilation against heimdal, but I don't have a cross-realm setup to test functionality under heimdal (though I also have no reason to think it wouldn't work). Since neither MIT nor heimdal provide a gss_userok() function, I used the krb5_userok() function. So if you're using a mechanism other than krb5 this won't work. But it's the same thing that OpenSSH and the apps distributed with heimdal do, so it seemed relatively safe. I also choose to append the krb5_userok() check rather than replace the gss_compare_name() check -- that way same-realm auth works for non-krb5 mechanisms, and my new code doesn't get called unless the same-realm check fails. If you don't care about other mechanisms it would be faster to bypass the gss_compare_name() check entirely. If this is something you'd like to mainline I'd be happy to standardize the coding style -- just point me to a style definition document. And if it doesn't hit the mainline I expect to maintain it for the foreseeable future, with updates at the same URL. Zach

[Dovecot] Dovecot, postifx, virtual domains and deliver, what about luser_relay/fallback_relay?
by Alexander Hoogerhuis 10 Oct '07

10 Oct '07

I've read documentation (obviously not the right parts) and googled, but I can't seem how to solve this simple problem: I have a machine running postfix/dovecot and using virtual domains, delivery happens with dovecot's LDA. I also have an Exchange machine that I have to house some of the users of a given domain. How can I tell either postifx in general or dovecot's LDA that whatever specific user that cannot be found in the virutal setup can be pawned off to a given relay-server which will sort it out? -A

[Dovecot] FW: IMAP proxy with dovecot and hostname
by Limperis Antonis 10 Oct '07

10 Oct '07

Good morning dovecot users I read in http://wiki.dovecot.org/PasswordDatabase/ExtraFields/Proxy that dovecot need ip address in host field and then "This field is required. Note that currently it's required to use an IP address since no DNS resolving is done.". I use a qmail cluster and Courier IMAP. In this system used the ldap field mailhost for proxy functionality with dns name as value. Is there a plan to add the DNS resolving to dovecot in host field; Is there any patch; Thanks Antonis

[Dovecot] User database ldap lookups and sasl
by Olivier Castan 10 Oct '07

10 Oct '07

Hello I'm currently trying to use Active Directory with Unix extensions to store UID, GID and homedir and retrieve them with ldap. I don't want to allow anonymous bindings and I would rather not use TLS and manage a PKI. So I'm trying to use SASL to do a Kerberos authentication for Dovecot against AD LDAP. I'm currently getting GSSAPI errors about the lack of "credentials cache". Looking at similar cases where services act as clients, like using nss_ldap for unix host accounts, I understand the credentials cache should be initiated by an external program (cron and startup script), at least with the TGT and maybe the TGS for ldap. Since usually kerberosv5 cache is based on the user id ( /tmp/krb5cc_0 for root) there's an option in ldap.conf (krb5_ccname) to set the filename (/etc/.ldapcache in nss_ldap tutorials) for this cache. Is there any way to do this with dovecot-ldap.conf or should I try to use "auth user" default cache filename ? Thanks in advance

[Dovecot] SpamAssassin and Public Namespace

[Dovecot] Dovecot hanging up with many defunct processes
by Mayank Joshi 09 Oct '07

09 Oct '07

Hi, I am in a very awkward situation and need some kind of immediate fix up. I had installed dovecot in my organization as part of migration of email server. The setup involves sendmail, dovecot (imaps+pop3s) and webmail (squirrelmail) running on apache webserver. All was working fine until one day I found a lot of defunct processes on system related to dovecot. dovecot-auth, imap-login and imap were all defunct. The system is using pam_ldap and nss_ldap to authenticate users to a Windows 2003 Active Directory. Immediate restart of dovecot solved the problem for me that day, however since then it's been about 3 times that I've faced this problem. After visiting various forums I came to know one thing, that it has something to do with pam_ldap and nss_ldap. However with UW-IMAP we were using the same setup and we didn't find any problems there. It would be very kind of you, if you can help me out on this front as apart from these mishaps the mail server is running perfectly fine and we wish to continue using Dovecot for our setup in future as well. Following is the system details: 1) OS: RHEL4 (Kernel - 2.6.9-5.ELsmp) 2) Dovecot: Dovecot (Version - 1.0.3) 3) Following is dovecot configuration: log_path: /var/log/dovecot.log protocols: imaps pop3s ssl_cert_file: /usr/share/ssl/certs/imapd.pem ssl_key_file: /usr/share/ssl/private/imapd.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 max_mail_processes: 10240 mail_location: mbox:~/mail:INBOX=/var/mail/%u 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_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): %08Xu%08Xv auth default: passdb: driver: pam userdb: driver: passwd 4) Dovecot's PAM file (/etc/pam.d/dovecot) #%PAM-1.0 auth required pam_ldap.so account required pam_ldap.so session required pam_mkhomedir.so skel=/etc/skel umask=0077 session required pam_ldap.so As far as I feel it's problem with pam_ldap not able to authenticate against Windows 2003 Active Directory due to some reason or the other. However I'm not sure why is this happening. Regards, Mayank Joshi.

[Dovecot] global sieve script
by Jorge Salamero Sanz 08 Oct '07

08 Oct '07

hi all, i'm moving from a maildrop+courier setup to lda(sieve)+dovecot setup. with maildrop i had a global filter for all the users, so i could filter and archive into the spam folder spam tagged emails for users without custom filters, including them if they exist: LOGNAME=tolower($LOGNAME) `test -e $LOGNAME` if ( $RETURNCODE != 0 ) { `maildirmake $LOGNAME` `maildirmake $LOGNAME/._spam` } `test -f $LOGNAME/mailfilter` if ( $RETURNCODE == 0 ) { include "$LOGNAME/mailfilter" } if ( /^X-Spam-Status: YES */) { to "$LOGNAME/._spam" } else { to "$LOGNAME/" } how could i get this behaviour with dovecot lda and sieve ? thanks !

[Dovecot] User database ldap lookups and sasl
by olivier castan 08 Oct '07

08 Oct '07

Hello I'm currently trying to use Active Directory with Unix extensions to store UID, GID and homedir and retrieve them with ldap I don't want to allow anonymous bindings and I would rather not use TLS and manage a PKI. So I'm trying to use SASL to do a Kerberos authentication for Dovecot against AD LDAP. I'm currently getting GSSAPI errors about the lack of "credentials cache". Looking at similar cases where services act as clients, like using nss_ldap for unix host accounts, I understand the credentials cache should be initiated by an external program (cron and startup script), at least with the TGT and maybe the TGS for ldap. Since usually kerberosv5 cache is based on the user id ( /tmp/krb5cc_0 for root) there's an option in ldap.conf (krb5_ccname) to set the filename (/etc/.ldapcache in nss_ldap tutorials) for this cache. Is there any way to do this with dovecot-ldap.conf or should I try to use "auth user" default cache filename ? Thanks in advance

[Dovecot] quota exceeded not showing email address
by JC 07 Oct '07

07 Oct '07

Hi everyone, I have a mail server with postfix 2.3.8-2, dovecot 1.0.0 and mysql with virtual users and domains. Everything is working but when a mail bounces it doesn't show me what is the email address with overquota. I'm using Dovecot Delivery Agent to send a mail when an email bounces. This is the message that shows me: Your message was automatically rejected by Dovecot Mail Delivery Agent. The following reason was given: Quota exceeded It doesn't show me what is the email address. In my /etc/postfix/master.cf I added this: dovecot unix - n n - - pipe flags=DRhu user=xyz:xyz argv=/usr/lib/dovecot/deliver -d ${recipient} In my /etc/postfix/main.cf I added this: dovecot_destination_recipient_limit = 1 virtual_transport = dovecot In my /etc/dovecot/dovecot.conf : protocol lda { postmaster_address = <postmaster-address> auth_socket_path = /var/run/dovecot/auth-master } ... user = xyz socket listen { master { path = /var/run/dovecot/auth-master mode = 0660 user = xyz group = xyz } } What should i have to show the email address?

Of course, you can leave it there, I've just said it is not necessary for dovecot to work.

Dear List, Am accessing dovecot imap through squirrelmail. Squirrelmail paginates the message list into pages. All works fine except for the page one particular email is in. When I try to open that page (or in fact click 'show all') the server returns: ERROR: Bad or malformed request.

Could you possibly let me know what I should do and also how I can find the guilty mail file from that error? Can I just delete the email? Or is there a nice script to repair a dovecot maildir?

[Dovecot] How to upgrade a running Dovecot?
by Mike Brudenell 06 Oct '07

06 Oct '07

Greetings - Could someone confirm how to perform various upgrades on a live system running Dovecot please? Scenario 1: Change to dovecot.conf =================================== If I make a change to dovecot.conf am I right in thinking I can simply send a HUP signal to the main dovecot process to get it to re- read the configuration file and act on its revised content? Scenario 2: Altered SSL Certificates ===================================== I need to replace our current certificates and have prepared new files containing the replacement certificate and private key. Am I right in thinking that I can simply modify dovecot.conf to point at the new files and send a HUP signal to dovecot? Specifically, will new connections use the revised certificates, and existing connections continue to work OK without interruption? Scenario 3: Software Upgrade ============================= I build a particular version of Dovecot into the tree /usr/local/ dovecot-A.B.C and then have a symlink called "dovecot" pointing at the this directory. To upgrade I can then build the new version into /usr/local/dovecot-X.Y.Z and test. To actually switch over the live service to the new X.Y.Z version do I need to: a) Totally shut down the old A.B.C version of Dovecot, thereby breaking all open connections for users? or b) Assuming I am using "shutdown_clients = no" can I just kill the master "dovecot" process and then start up the new version? Ideally I want existing connections to remain running, but new connections to start up using the new X.Y.Z version of Dovecot. The comment for "shutdown_clients" implies this, but also says: "This however means that after master process has died, the client processes can't write to log files anymore." So if I understand this correctly then with "shutdown_clients = no" in force then the sequence and behaviour is this? ... 1. Old version A.B.C of Dovecot running, clients can log through the master "dovecot" process to the logfiles. 2. Kill the old master "dovecot" process, start new X.Y.Z version up. 3. New connections get served by version X.Y.Z. Old connections DON'T get killed and can continue, BUT can no longer write anything to the logfiles?

[Dovecot] "Corrupted index cache file" error (Dovecot 1.0.3)

Greetings - Now that users are beginning to pile up more on our new Dovecot-based IMAP service I'm seeing a small number of entries like this in the logfiles: Corrupted index cache file /mailstore/index/o/ozw100/.INBOX/ dovecot.index.cache : invalid record size We are using Dovecot 1.0.3 with Maildir folders served over NFS from NetApp filers, but the index files are stored on local disk. By "a small number" I mean 4 or 5 on each of our two IMAP servers since midnight. * Should I be worried? * Is there anything I need to do fix the files? (I'm guessing not as no problem reports have come in, and the logs show the people affected continuing to work throughout the day.) * Would upgrading to 1.0.5 help?

[Dovecot] Custom password encryption scheme, how to do it?
by Madison Kelly 06 Oct '07

06 Oct '07

Hi all, I'm a fairly recent convert to Dovecot/Postfix from Sendmail, so please be gentle (and assume I know nothing). :) I've got a Postfix/Dovecot/PostgreSQL setup with a custom DB schema for my email. This database is also used for a bigger program I use for all my hosting needs (domains, etc.). Currently, I've set it up to use plain-text authentication while I was developing it and getting things running. Now though it's up and running fine, so I want to increase the strength of my passwords that Postfix/Dovecot use. I currently have two fields in a table called 'users'; 'usr_password' which is plain-text and what Postfix/Dovecot currently use and 'usr_strong_password', which stores a stronger hash and is used by the main program. My question is, can I have Postfix/Dovecot use a custom password hashing system? The way I store my strong password (as used by the web-interface) is; - Take the password provided from the user - Read a stored 'salt' value from the database (unique per user and changed on password [re]sets). - Generate an initial SHA256 hash out of the password+salt. - Re-hash the initial SHA256 hash many thousands of times. - Compare the final hash with the hash stored in 'usr_strong_password'. If I can tell Dovecot how to do this, where would I do it? Is there a document/howto/etc someone could point me to? Is there a file I should look at? Thanks all!! Madi

[Dovecot] Dovecot + OCFS2
by Jon Blazquez 06 Oct '07

06 Oct '07

Hello, We are running Red Hat Enterprise Linux AS release 4 (Nahant Update 4) with OCFS2 for our mail servers. There are three nodes in the cluster with shared storage and OCFS2 filesystem on it. The filesystem is used for mail storage(using Maildir layout) and is accessed by smtpd, pop3 and imap processes(DOVECOT). The system works fine but when there are mailing lists the load increases dramatically. It only occurs when there are mailing lists. We have tested it in lab with good results and now in production we are having some load problems caused by dovecot´s deliver process. In lab we had sent lots of mails but always to a few accounts. It was OK. Now there are sent less mails but there are more accounts. The load increases until it reaches about 100 and only restart fixes the problem. The umounting of the OCFS2 filesystem is not possible even when all process accessing it are killed. Any suggestions? TIA Info: Three nodes. OS: Red Hat Enterprise Linux AS release 4 (Nahant Update 4) Mailbox format: Maildir SMTP daemon: Dovecot deliver + Sendmail OCFS2 version: 1.2.5-6 Kernel Version: 2.6.9-42.0.10.ELsmp Pop3 and imap daemon: Dovecot 1.0.3 -- _________________________________________________ Jon Blázquez Diez jblazquez(a)unav.es Servicios Informáticos https://www.unav.es/SI/ Universidad de Navarra https://www.unav.es _________________________________________________

[Dovecot] Subscribe to root of Maildir namespace?
by Adam Tilghman 06 Oct '07

06 Oct '07

Our users currently make use of a single namespace, mbox format: namespace private { separator = / prefix = hidden = no inbox = yes location = mbox:~/:INBOX=/var/spool/mail/%u:INDEX=/var/spool/poptemp/dovecot/%u } I'd like to give them access to additional Maildir-format storage area, so to the above I've added: namespace private { separator = / prefix = archive/ hidden = no location = maildir:/newmail/%-3.3i/%u/:INDEX=/var/spool/poptemp/dovecot/%u.a-thumper-mail } I can set up subfolders of archive/, and they work as expected. I can also designate the "root" of archive/ as INBOX and that works properly. But "SUBSCRIBE archive" fails. Is it possible to subscribe to the "root" of this new Maildir heirarchy as if it were just another folder? If not, would this be a useful feature to add?

[Dovecot] problematic ACL with shared folders and maildir
by Dominik L. Borkowski 05 Oct '07

05 Oct '07

Hello, Recently we have been asked to deploy some shared imap folders within our instance of dovecot. However, we ran into a problem with how ACLs are implemented, and consequences regarding maildir++ mailboxes. Long story short: * IMAP clients sees the hierarchy as a tree: sample/1, where 1 is a child of sample * on the filesystem, sample/1 is represented as .sample and .sample.1, both on the same level This presents a problem: dovecot-acl file meant for sample mailbox does not apply to mailbox 1. In fact, a user with permissions to create mailboxes under sample, will not be able to access those mailboxes, once created. Wonder if anybody has been in a similar predicament, and found a solution. Any hints would be greatly appreciated. PS) I'm also documenting this process, maybe others will find it useful: https://collaboration.vbi.vt.edu/display/~dom/dovecot+-+shared+imap+folders -- Dominik L.

[Dovecot] Deliver prints passwort to the syslog
by Dominik Schulz 05 Oct '07

05 Oct '07

Hi, I've got the problem that dovecot's deliver prints the authentification information to the syslog. Like this: Sep 18 12:11:22 mail deliver(user(a)domain.tld): auth input: user=user(a)domain.tld Sep 18 12:11:22 mail deliver(user(a)domain.tld): auth input: password=XXXX Sep 18 12:11:22 mail deliver(user(a)domain.tld): auth input: home=/home/mail/domain.tld/user Sep 18 12:11:22 mail deliver(user(a)domain.tld): auth input: uid=8 Sep 18 12:11:22 mail deliver(user(a)domain.tld): auth input: gid=8 I guess that it's only a configuration option but right now I can't figure out which one I need to change to turn this off. Any help would be appreciated. Thanks in advance. Best Regards Dominik

[Dovecot] UIDL and IMAP
by Kenneth Porter 04 Oct '07

04 Oct '07

I finally got my aging FC2 box retired and moved all email to my new CentOS 5 box. My site is all-IMAP, no POP3. I have one user who downloads all email to Thunderbird on his laptop so that he can work offline while away from a network connection (eg. on an airplane). I forgot to change the pop3_uidl_format setting as described here: <http://wiki.dovecot.org/Upgrading/1.0> So he was seeing repeated downloads of all his mail (about 300 MBytes) every time he connected. (I'm not sure why it didn't happen only the first time.) I changed the setting and haven't heard back whether if fixed things for him. Does this setting in fact get used by IMAP? It's in the POP3 section, so I'm wondering if it takes effect when one is using IMAP from the client. CentOS 5 is currently shipping with: dovecot-1.0-1.2.rc15.el5 I may look for a newer release. CentOS, based on RHEL, is intended to be a conservative distro, so I'll probably need to look at RPMForge (an addon repository of more exotic and bleeding edge software) to see if it offers a newer release.

[Dovecot] Dovceot user pop3 last connect info?
by Tim Tyler 04 Oct '07

04 Oct '07

Dovecot experts, I am a newbie to Dovecot. I am in the process of replacing qpopper with dovecot to support pop 3 clients. I have installed the latest version of Dovecot on Fedora Core 6. Everything seems to be working fine using ldap, etc. However, with qpopper, I used to have .pop.username files which would give me a time stamp of the last time a user established a pop3 connection. I know that Dovecot has logs of connection in the /var/log/maillog files, but these files rotate out over a relatively short period of time. Is there a method by which one can keep track of the last time a pop3 connection was established for each user when using Dovecot? Tim Tyler Network Engineer - Beloit College tyler(a)beloit.edu

[Dovecot] In-site migration from /etc/passwd to LDAP
by Maykel Moya 04 Oct '07

04 Oct '07

I'm doing in-site migration of accounts from /etc/passwd to an LDAP directory. The migration should be progressive (not all users at the same time). I'm already able to check mail for accounts in /etc/passwd and accounts in LDAP. The problem is with mail delivery. I'm using Postfix + Dovecot-LDA. This is the error I get with every delivery -- dovecot: Oct 03 00:16:09 Info: auth(default): master in: USER 1 moya service=deliver dovecot: Oct 03 00:16:09 Info: auth(default): ldap(moya): user search: base=ou=users,dc=sld,dc=cu scope=subtree filter=(&(objectClass=posixAccount)(uid=moya)) fields=sldMailbox,uidNumber dovecot: Oct 03 00:16:09 Info: auth(default): master out: USER 1 moya home=/srv/vmail/m/moya/ uid=29174 gid=101 deliver(moya): Oct 03 00:16:09 Fatal: setuid(29174) failed: Operation not permitted -- 29174 is the uid for moya, is the same in /etc/passwd or in LDAP via posixAccount class. Any advise please? Regards, maykel

[Dovecot] new antispam plugin
by Johannes Berg 03 Oct '07

03 Oct '07

Sparked from the discussion on the list, I've put my antispam plugin into git and split up the code into a frontend and possibly multiple backends. See http://git.sipsolutions.net/dovecot-antispam.git/ (URL functions as both gitweb and git URL) Andreas, I took your README file and adjusted it, I hope you don't mind. I didn't fork from your git tree because you'd already implemented the libdspam backend there. Maybe you could take a look at the new backend/frontend separation and implement a libdspam backend. Aria, it should be possible to write a spamassassin plugin, quite easily if spamassassin supports training based on signatures, not quite so easily otherwise though I intend to plan this. Timothy, you could write the mysql logger as a backend too. I take patches :) Oh and as always thanks to Timo for implementing such a nice server and string, memory and mail handling API. johannes

[Dovecot] --enable-headers-install problem in 1.0.5
by Trever L. Adams 02 Oct '07

I am trying to get a SPEC file for an RPM to build a devel package. I have it working, except for one thing. 1.0.5 doesn't actually install the headers with that option to configure found in the subject. It does create the directory, but it doesn't put the files there. Timo, is this a known/unknown bug, or am I doing something stupid? Thanks, Trever

[Dovecot] SORT(DATE) and missing Date headers
by Kyle Wheeler 02 Oct '07

02 Oct '07

Hello, Occasionally, I get mail that's missing a Date header. The usual suspects are iTunes weekly mailings and NYTimes email-to-a-friend articles. I use qmail, which doesn't "fix" these malformed emails by adding a Date header (like Sendmail does), so when they get to my mailbox, they're just as badly formed as they were when they were sent, which is to say, they have no Date header. Unfortunately, this means that SORT (DATE) puts them at the beginning of the list---and in a mailbox with lots of old mail, that's usually the wrong spot. Now, my email clients will do some basic guesswork about when the message was sent, usually by falling back on the timestamp of the first-added Received header. So, they will display a date. But they have to then sort all messages themselves in order to get a valid sorting. Would it be possible to get Dovecot to fall back to Received header parsing whenever a message is missing a Date header? The idea is that SORT (DATE) would then become useful even in the face of commonly malformed email. How hard would this be to hack into the current Dovecot source? Does this maybe exist already (e.g. as SORT (X-DATE)? ~Kyle -- There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo. Please use in that order. -- Ed Howdershelt

[Dovecot] Slight problem with dovecot + IMAP
by Timothy Murphy 02 Oct '07

02 Oct '07

I'm running dovecot on my desktop with kmail as IMAP client on my laptop. When I start kmail on the laptop it sometimes takes several minutes to "calm down". The number of messages listed in the IMAP inbox increases greatly - maybe from 2500 to 3000 - and then slowly decreases. There are sometimes a large number of duplicate messages, which kmail allows one to delete. I don't know if this is a kmail or dovecot problem. It is quite likely there is something wrong in my setup. Any suggestions or advice gratefully received.

[Dovecot] IMAP Fetch fails with BAD instead of NO
by Reinier Bezuidenhout 02 Oct '07

02 Oct '07

Hi, I'm running version 1.0.3 of dovecot using IMAP and using javamail to access the mail. The application I'm using (when stress testing the system by doing simultaious creation of email and deleting emails, it sometimes get into the state where the application (via javamail) ask for the UID of a message that has been expunged and deleted (no longer exists). Dovecot returns with the following error: AXXX FETCH 14 (UID) AXXX BAD Error in IMAP command FETCH: Invalid messageset This can easily be reproduced by using telnet to 143 and giving the command by hand. When I read through the source code, there were obvious comments that states the dovecot will not return NO on fetch errors, only BAD. So I assume it is done on purpose. My question is that in RFC 3501 for fetch it says: (section 6.4.5) Result: OK - fetch completed NO - fetch error: can't fetch that data BAD - command unknown or arguments invalid No I guess a UID that is out of range could be considered "arguments invalid", but shouldn't it be a soft error with NO as a result where "can't fetch that data" is more appropriate according the the RFC. The command isn't syntactically BAD, the requested data just does not exists. The same command tested against another IMAP server returns AXXX NO message not available Not that they are necessarily correct, but it just begs the question.

Hi to all, very strange! I tried to debug why imap process takes 100% CPu and it is very slow when I move an email from an imap folder to another imap folder and then I typed: strace -tt -o /log-imap.txt -p <process number> well, during the trace the imap process doesn't crash and it is very fast. If I stop the tracing, I have again the problem and sometimes the crash of the process. Any help?

[Dovecot] plugin problem
by Lars Stavholm 02 Oct '07

02 Oct '07

I'm trying to do a rewrite of the dspam_plugin for dovecot 1.1b1. There are some API changes that warranted an update of the plugin. Also, I wanted the dspam_plugin to be able to handle pristine mails for dspam retraining, as opposed to the signature based retraining. Question: How can I retrieve the full unix path for a specific mail? The original code uses mail_get_first_header() to retrieve the signature header. I need something like mail_get_mail_file_path(&path) which I then could pass on to dspam. Is there some such function available? Thanks in advance /Lars

[Dovecot] shared mailboxes question
by Cory Coager 01 Oct '07

01 Oct '07

I'm using a virtual mailbox setup. Lets say my users have mailboxes in /home/vmail/domain/%u. What I'm trying to do is setup one namespace that points to /home/vmail/domain and contains everyones mailboxes that I can subscribe to. Is this possible? I tried using a symlink to /home/vmail/domain but it doesn't work because its looking for the dotFoldername. The only way I could get this to work is by creating a symlink for each folder in every mailbox. This is way too much maintenance especially since it will dynamically change. The only other way I could get it working was to create a namespace for each user and point to /home/vmail/domain/%u/Maildir/. Then inside everyones Maildir/ create a symlink for INBOX -> . This works but I'd have to do it for each user when I'd rather just use one namespace. Is there an easier way of doing this?

[Dovecot] Opinions on preferred namespace?
by Ed W 01 Oct '07

01 Oct '07

Hi Any opinions on a preferred namespace setting for use with Dovecot? Deciding factors seem to be client support, not being too unusual, accidental ease of setup, wider character range support (eg dots in folder names?), issues when scripting imap commands? For example Outlook Express (common with our userbase) seems to assume no folderprefix when using our current Courier server and from memory I think this causes some subtle issue with Sent Items and Drafts folders until you tell it to use an INBOX. folder prefix? (can't recall the exact details right now) I notice also that Thunderbird will show all folders under "Inbox" if I have an INBOX. prefix, but shows them all in a list if there is not one. Actually I find the former quite a useful feature because I have a number of test accounts where I only want to click into the INBOX, do I can keep the list of folders closed up Any other programs exhibit any (possibly beneficial) side effects from different prefix choices? Anyone got any preferences either way? Any pros/cons in using a dot as folder separator rather than a slash? I can see some logic in using an INBOX folder prefix and a slash as the folder separator because this would then mimic the on-disk layout.. (Is this what cyrus does?) I mainly care about best support for Outlook Express / Windows Mail and Thunderbird - any opinions on most compatible settings? Cheers Ed W

Correct. If the folder does not exist, maildrop will create it on first delivery. If the end user deletes the folder, maildrop will recreate the folder on the next message delivery to that account.

[Dovecot] 1.1b1 initial pop3 login: assertion failed

[Dovecot] v1.1.beta2 - maildir quota calculation problem
by Andrew Pavlenko 01 Oct '07

01 Oct '07

I have a problem with the maildir quota plugin. Any imap operations cause the plugin to recalculate the mailbox size and put the new value in the second line of the maildirsize file, while the third line always contains the size of the latest operation. So the resulting sum is incorrect. Moreover, quota-warning is not working either. Have anybody else met such problem? mail# ./dovecot -n # 1.1.beta2: /usr/local/etc/dovecot.conf ... mail_plugins(default): quota mail_log mail_plugins(imap): quota mail_log 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 ... plugin: quota: maildir quota_rule: *:storage=10240 quota_warning: storage=75%% /usr/local/etc/quota-warning.sh 75

[Dovecot] Mixed Courier POP3 and Dovecot IMAP environment
by Jan van den Berg 01 Oct '07

01 Oct '07

Hi, Currently we support Courier POP and IMAP for all our users (users can use IMAP as well as POP at the same time). We are thinking about moving to Dovecot; but first moving away from Courier IMAP to Dovecot IMAP (and maybe later also move to Dovecot POP). This would create a mixed environment; after some research I have the following questions. To not break POP3 Courier and still be able to use Dovecot IMAP: - I have to use the namespace prefix in the dovecot.conf file: I read this in the wiki. - "Patch" the source so Dovecot IMAP will look for/use 'courierimapuiddb' instead of 'dovecot-uidlist': otherwise I guess POP3 and IMAP users will have different UID files, right? Is this smart or will this still break the UID file? - "Patch" the source so Dovecot IMAP will look for/use 'courierimapsubscribed' instead of 'subscriptions' of should I just go with the renaming of the files? I'm thinking about patching so the transition can be as transparent as possible: Also if anything might go wrong in production I want to be able to switch back to the 'old' Courier IMAP (without renaming files etc.) Any thoughts on this? Cheers, Jan

[Dovecot] Released v1.1.beta2
by Timo Sirainen 01 Oct '07

http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta2.tar.gz http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta2.tar.gz.sig Several bug/crashfixes. deliver now supports -a parameter (see http://wiki.dovecot.org/LDA) which allows Sieve plugin v1.1.2 to use envelope :detail "to" checks. I also did one more API change for mailbox_transaction_commit*(). There's probably something still wrong with SORT command, but other than that I've fixed everything that's been reported.

[Dovecot] Maildir ignore
by Tomas Horacek 01 Oct '07

01 Oct '07

Hello there. I do like Dovecot so far, but ran into problem I cant seem to solve, maybe someone can point me into right direction please. I am running version 1.0.rc15 on CentOS 5 Linux i386 system, ext3 fs. The problem is I cant get the maildir: and :ignore to work together. Here is my SQL query, that includes the Quota field. # cat /etc/dovecot-sql.conf | grep -i quota user_query = SELECT maildir AS home, 901 AS uid, 901 AS gid, CONCAT('maildir:storage=', floor(IF(quota!=0, quota,-1)/1000), ':ignore=Trash') AS quota FROM mailbox WHERE username = '%u' AND active = '1' Even Dovecot agrees it seems correct. # cat /var/log/maillog | grep kaktus | grep quota\= | tail -n1 Sep 30 23:37:33 XXXXXX dovecot: auth(default): master out: USER 5 XXX(a)XXX.cz home=XXX uid=901 gid=901 quota=maildir:storage=1024:ignore=Trash I hope this is the correct way. Looking at IMAP communication with Wireshark, the server seems to ignore my settings. 118 uid copy 22 Trash\r\n 118 NO Quota exceeded\r\n Anyone can help me, please ?

[Dovecot] dovecot-dspam plugin & virtual users
by Wicher Minnaard 30 Sep '07

30 Sep '07

Hi list, hi Johannes, I'm trying to use the dovecot-dspam plugin ( http://johannes.sipsolutions.net/Projects/dovecot-dspam-integration ) with vpopmail's virtual users. All seems well, except for the fact that dspam should be called with '--user currentuser(a)currentdomain.com' at line 157 here: http://johannes.sipsolutions.net/Projects/dovecot-dspam-integration/beta7-c… For my needs, 'currentuser@currentdomain' could be taken as the login name I use for logging in to Dovecot. As I'm not a C-programmer by a long shot, I was wondering if one of you could help me use the bincimap-API to import the login name into a variable so I can use that variable to construct a suitable dspam-command. Hope this is possible! Regards, Wicher Minnaard

[Dovecot] dovecot dspam plugin using libdspam
by Andreas Schneider 30 Sep '07

30 Sep '07

Hi, I've found the dovecot dspam plugin and looked at the code. I forks and calls the dspam binary for every mail. I didn't like this behavior, so I've migrated it to use libdspam. The plugin still needs more love: * Use cmake instead of a Makefile * Make the spam folder configurable in the dovecot.conf * Code cleanup and more comments. Please test. Comments and patches are welcome ;) http://www.cynapses.org/tmp/dovecot-dspam-plugin-0.1.tar.gz Cheers, -- andreas -- http://www.cynapses.org/ - cybernetic synapses

[Dovecot] Problem with manually moving maildir files between folders

Hi! Is there a way to log the file that have been copied when a person move it from a folder to another using mail_log?

[Dovecot] Subaddress Extension in sieve plugin
by Frank Behrens 30 Sep '07

30 Sep '07

Hello! With many MTAs it is possible to use a special form of adressing: subaddresses or "plussed addresses". For sendmail you can read some information on http://www.sendmail.org/m4/misc_features.html http://www.unix.org.ua/orelly/networking/sendmail/ch24_04.htm#SML2-CH-24-SE… In a sieve filter you can analyse these special detail values, the syntax is described in RFC3598 (http://tools.ietf.org/html/rfc3598) The current deliver with sieve plugin for dovecot seems to support this RFC, but has the detail information not available. If I use require ["subaddress", "fileinto", "reject"]; require "envelope"; if envelope :detail "to" "junk" { fileinto "junk"; } the rule is not triggered, because the detail information from envelope is not available. Deliver gets the user information only via command line switch "-d". I did not analyse the problem very deep, but I believe we should introduce a new command line parameter for deliver, so deliver can pass the detail information to the sieve plugin. With that parameter you are able to pass the detail information from sendmail to devecot's deliver in the same way procmail is handled (procmail uses -a parameter). To avoid confusion: deliver has already a parameter -m to specify a different mailbox. In the described case the mailbox should be determined by the sieve filter, not via command line parameter. Existing workaround: Because I need this functionality I wrote a quick (and dirty?) workaround. Sendmail does not call deliver directly, but a wrapper program, that adds an additional "Delivered-To" header line. So the detail information may be processed with if address :detail ["Delivered-to"] "junk" { but I would prefer to call deliver directly. What do you think, is it a useful extension and does it work?

[Dovecot] v1.1.beta1 POP3 delete problem
by arvids 30 Sep '07

30 Sep '07

Hello, POP3 server does not delete mails when user quits POP3 session, but only at the next login. It looks so - user logs in with USER and PASS commands, at this moment new messages are moved from /new to /cur maildir folder. Then messages are deleted with DELE command(before deleting there can be other POP3 commands) and the user quits session. The server says "+OK Logging out, messages deleted.", but in fact messages are not deleted from the disk and stays in /cur folder. And these messages are deleted only when user logs in next time. dovecot -n: # 1.1.beta1: /usr/local/dovecot/etc/dovecot.conf base_dir: /var/run/dovecot/ syslog_facility: local0 protocols: pop3 ssl_disable: yes disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/local/dovecot/libexec/dovecot/pop3-login login_greeting: Server. login_process_per_connection: no login_process_size: 64 verbose_proctitle: yes first_valid_uid: 95 first_valid_gid: 95 mail_uid: 95 mail_gid: 95 mail_location: maildir:~/Maildir mail_debug: yes fsync_disable: yes mail_executable: /usr/local/dovecot/libexec/dovecot/pop3 mail_plugins: quota mail_plugin_dir: /usr/local/dovecot/lib/dovecot/pop3 pop3_enable_last: yes pop3_client_workarounds: outlook-no-nuls oe-ns-eoh auth default: mechanisms: plain login digest-md5 cram-md5 apop cache_size: 2048 cache_ttl: 28800 cache_negative_ttl: 60 user: doveauth verbose: yes debug: yes debug_passwords: yes passdb: driver: sql args: /usr/local/dovecot/etc/dovecot-sql.conf userdb: driver: prefetch userdb: driver: sql args: /usr/local/dovecot/etc/dovecot-sql.conf socket: type: listen master: path: /var/run/dovecot/auth-master mode: 384 user: vmail group: vmail plugin: quota: dict:::proxy:/var/run/dovecot/dict-server:quotadict dict: quotadict: mysql:/usr/local/dovecot/etc/dovecot-sql-dict-quota.conf Regards, Arvids

[Dovecot] v1.0 vs 1.1b re: Postfix and Dovecot LDA
by Jerry Yeager 30 Sep '07

30 Sep '07

In running the various 1.0.n versions of Dovecot's LDA with the instructions in the wiki for using LDA with Postfix [on OS X 10.4] things went well using the instructions as-is (no setuid problems). This changed in moving over to the 1.1 beta. The LDA refused to work failing with the error "setgroups() failed: Operation not permitted" as I mentioned in a previous message. After reading the exchange between Bill Cole and Rich Winkel and following up on this, it seems that the new 1.1b wants you to give the Deliver app specific setuid permission via: cd /path/to/where/dovecot's/deliver/is sudo chmod u+s deliver Then things worked as before. There was no need to give the group 's' permission nor to change ownership of deliver from the default root:staff or root:wheel or whomever... . The error message seems odd though. I am not sure if, overall, this means there is a problem in Dovecot 1.0.n or that things are being tightened up in 1.1b. Thanks Bill and Rich for the tip! Jerry Yeager

I don't see this as a problem at all (why create one when there's none to be found:): * Move message into Spam: it's a spam that should be reclassified. * Move message out of Spam: it's a ham that should be reclassified. Don't really care where the mail comes from or where it is moved. This is the beauty of it all, count the key or mouse clicks, can't be less than this:) * Using the expire plugin, the Spam folder will be emptied auto- matically in due time (typically 30 days maybe) without user intervention. All close to zero maintenance for sysadmin as well as end-user. > Well, by now I dont have much, but I really would like to know how to > find the filename of a message being copied from a folder to another. No such luck (I think): to my understanding (with the help of Johannes in previous reply in this thread), you'd have to create a temporary file with the mail message using tmpnam() + mail_get_stream() or similar, and then do your thing. I'm aiming towards that exact functionality: I want to be able to do training using "pristine" source (so I'll need the whole message), and keep the previous functionality using signatures. We'll see how it goes. Good Luck and thanks for your input /Lars

[Dovecot] Configure/install path overrides
by Remy Zandwijk 30 Sep '07

30 Sep '07

Hi, I'm building and installing dovecot on a Solaris 10 machine and therefore I want to install Dovecot in /opt/dovecot. Thus, I start configure with --prefix=/opt/dovecot. I also override things like 'libexecdir', 'docdir', etc. When calling make install, Dovecot is installed in /opt/dovecot, but for example the binary user files are installed in /opt/dovecot/bin/dovecot. The same for the docs, which are installed in /opt/dovecot/share/doc/dovecot. I think that's not quite nice and neat, so I call 'make install' like: make docdir=/opt/dovecot/share/doc install. But even then, the wiki stuff is still installed in /opt/dovecot/share/doc/dovecot/wiki in stead of /opt/dovecot/share/doc/wiki. Very anoying. My point is that ./configure should be able to override all paths, but since some paths are somehow hard-coded in the Makefile, this is impossible. Any chance this will (be) change(d) sometime? -Remy

[Dovecot] deliver w/quotas - MDN after accept mail?
by Ken A 30 Sep '07

30 Sep '07

I'm testing deliver with sendmail and fs quotas. On an over quota condition, deliver accepts the mail, deletes it, then issues a MDN immediately. Is there a way to get deliver to soft fail like procmail does with a 400 error and queue the mail, then let sendmail handle the MDN, following it's "confTO_QUEUEWARN" and "confTO_QUEUERETURN" ? Thanks, Ken -- Ken Anderson Pacific.Net

[Dovecot] Testing sieve filter
by Cliff Meece 28 Sep '07

28 Sep '07

Hi, I am trying to get sieve working with dovecot. Dovecot itself is working fine, and I have the following config: root@master:/var/log# dovecot --version 1.0.rc2 root@master:/var/log# dovecot -n # /etc/dovecot/dovecot.conf log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap ssl_disable: yes disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login mail_extra_groups: mail default_mail_env: maildir:/var/mail/%u auth default: passdb: driver: pam userdb: driver: passwd I have this in my lda protocol: mail_plugins = cmusieve And I have created a .dovecot.sieve in both ~ and /var/mail/$user/ that looks like this: require "fileinto"; if exists "X-Spam-Flag" { fileinto "Junk"; } No mail gets moved to the junk folder, nut it does arrive in my inbox with the X-SPAM-Flag: Yes header. How do I troubleshoot this? I don't see anywhere in the logs any errors or any mention whatsoever of filtering activity or failure. I have seen numerous pages on how to set this up, but they invariably focus on setting up virtual users, which I do not need, so it isn't clear which steps I can safely ignore. thanks in advance, Cliff

[Dovecot] Documentation to create plugins.
by "Fábio M. Catunda" 28 Sep '07

28 Sep '07

hi! Is there any documentation to guide me how to create a dovecot plugin? I'm trying to read the code, but I'm not a good C programmer. I have been able to copy the mail-log plugin into copy-log, edited about 4 lines of code, then I edited Makefiles and configure, now I'm able to compile, install and use my "new" plugin. Anyway, any help is appreciated. Thankz! !DSPAM:46fd34b1153407177711712!

I have it (deliver) in a restricted access folder as a standard safety precaution, but as most of these "jails" end up being only safe for a short time I have again gone back to using Postfix as the deliver. Timo has from time to time mentioned that he was thinking that deliver needed to be rewritten. hmmm. I still give you and Rich credit though, if you had not mentioned the ideas behind Sendmail and LDA, it would most likely taken much longer before I read that wiki entry and gave that approach a try, instead of trying to find the missing setting for changing groups that the error message wants fixed. > -- > Bill Cole > bill(a)scconsult.com > > > > ------------------------------ > > Message: 7 > Date: Thu, 27 Sep 2007 17:07:28 -1000 (HST) > From: Julian Cowley <julian(a)lava.net> > Subject: [Dovecot] Dovecot raw backtrace when copying to folder > To: dovecot(a)dovecot.org > Message-ID: <alpine.LRH.0.9999.0709271646190.28814(a)taurus.cesta.com> > Content-Type: TEXT/PLAIN; format=flowed; charset=US-ASCII > > Seeing a problem with a certain user causing dovecot to crash when > copying > mail to a folder.

[Dovecot] dovecot IMAPS + kmail
by Timothy Murphy 27 Sep '07

27 Sep '07

I notice that kmail does not allow an IMAP sub-folder to be created (from an IMAPS client). When I try, kmail says this cannot be done for one of the following reasons: Your access permissions may be inadequate to perform the requested operation on this resource. The location where the folder was to be created may not exist. A protocol error or incompatibility may have occurred. Is there any simple way of getting round this? KMail has no problem creating top-level IMAP folders.

[Dovecot] filtering when mail is moved to IMAP Inbox
by Rahul Amaram 27 Sep '07

27 Sep '07

Hi, I have been looking for a solution to this problem for quite sometime but just haven't got any. This is how my current set up is. I have a IMAP Server installed on my home server. It has various folders. I have configured Thunderbird in my laptop to connect to the IMAP Server and access mails. I have also configured Thunderbird to download mails from my GMail account using POP3. I have set up a filter in Thunderbird to move all my mails which come to my Local Folders "Inbox" to my IMAP Server's Inbox. Now here is my question - Is it possible to set up some rules in the IMAP Server (maybe sieve) so that I can filter the messages coming to its Inbox and move them to another folder? The whole idea is that I have control over when I want to fetch mails from my GMail account but at the same time the filtering rules for moving to custom folders should be stored on the server so that i do not replicate this in every client. Regards, Rahul. -- http://rahul.amaram.name

[Dovecot] blackberry with imap idle and concurrent connections
by Chris Tirpak 26 Sep '07

26 Sep '07

Hello - I've combed the wiki and archives a bit and can't seem to find what I am lookng for. It seems that BlackBerry Internet server has an issue with IMAP accounts along with IDLE and concurrent connections. Please see the following link (sorry it's fairly long): http://www.blackberry.com/btsc/search.do?cmd=displayKC&docType=kc&externalI… It appears as though IDLE can be implemented without "concurrent connections". Courier appears to do this although they have an option to turn it on. At first blush it seems obvious that any mail server will permit concurrent connections but as I read the docs for Courier and BlackBerry it appears to be a subtle thing whereby IDLE allows more than one connection to IDLE against the same IMAP folder when using maildir. Does Dovecot support his? Also, if anyone on the list has experience running a BlackBerry against Dovecot, are you currently getting instant (or near instant) notifications? If so what service are you using? T-Mobile? I am considering upgrading and using Dovecot but BlackBerry support has become critical. Thanks in advance. Chris

[Dovecot] Moving email from a folder to another using IMAP is very slow (sometimes)
by Stefano Scalise 26 Sep '07

26 Sep '07

Hi to all, I am using the new beta release 1.1. I am experiencing, after the upgrade to the 1.1beta some problems regarding the following scenario: I am conneted with Outlook to dovecot server using IMAP. I have many folders and I want to move an email from a folder to another using drag and drop. I see that when I move the email, the IMAP process goes to 90-95% for about 5 seconds and after, the mail is finally moved. I noticed that this operation sometimes (20% about) is again fast. There is no problem of overload of the server because this mail server, at the moment, manage just 1 email address. Before the upgrade to 1.1beta, this operation was very very fast. Is there a way to try to debug the IMAP process for understanding what is happening? Thank you for your help. Stefano.

[Dovecot] user_global_uid and user_global_gid
by Stefano Scalise 25 Sep '07

25 Sep '07

Hi to all, I am using the new beta release 1.1. I see that parameters user_global_uid and user_global_gid are no more used in dovecot-ldap.conf. That means that, as I use LDAP as backend I am obliged to se t these two fileds in LDAP for each user even if they are always the same, as I use virtual domains. I see that I can set the in dovecot.conf the parameters mail_uid and mail_gid, but even if I set these parameters, when I do the query in LDAP (for retrieving other useful parameters) I have the error: userdb(<email address>) didn't return uid but... I don't want to take uid parameter from LDAP, I want to set it globally but I still want to do an LDAP query. Is there a way to do this in the new evrsion or I cannot do anymore this? Thank you, Stefano.

[Dovecot] v1.1.beta1 released
by Timo Sirainen 25 Sep '07

25 Sep '07

http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta1.tar.gz http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta1.tar.gz.sig Alpha6 seemed to finally work quite well, so I think it's time for a feature freeze (except for dbox changes). I started a new wiki page to list incompatibilities between v1.0 and v1.1: http://wiki.dovecot.org/Upgrading/1.1 Fixes since alpha6: - deliver + maildir caused "UID 0 in transaction log" errors - deliver + maildir no longer blocks if dovecot-uidlist.lock file exists. The mail is simply delivered without updating uidlist or indexes. - Quota handling fixes, especially dict quota - etc.

[Dovecot] pam session=yes with gssapi authentication
by Thomas Mueller 25 Sep '07

25 Sep '07

hi there I noticed the following behaviour with auth backend pam and "args session=yes *" configuration: - login with "plain": pam session gets opend - login with "gssapi" (kerberos): pam session isn't opend (-> no $HOME will be created) Is this a bug or just a limitation by GSSAPI (maybe gssapi works around PAM)? - Thomas Dovecot Versions seen this: - 1.0.rc15 (Debian 4.0 Etch) - 1.0.0 (Debian backports)

I find the statement that dovecot has maildir format support misleading. By maildir support, I mean that mail is contained in directories ~/Maildir/inbox/[cur,new,tmp], ~/Maildir/Family/[cur.new.tmp], ~/Maildir/Finance/[cur,new,tmp], etc. This is the setup created if one runs kmail as mail client, specifying that one is using maildir format, and using the GUI to create new folders Family, Finance, etc. As far as I can see, if you now set up an IMAP server using dovecot on this machine, setting mail_location = maildir:~/Maildir/ in /etc/dovecot.conf then the email in the folders Family, Finance, etc will not be seen by an IMAP client. > But as soon as you have an e-mail klant using a non-supported mailbox > format *or* that is storing mail folders in a supported format but in > a non-standard place, tour theory applies, yes. What is the "standard" place for mail folders? > See also <http://wiki.dovecot.org/> for more info about this all. I've studied that wiki, and not found clear information on this point. To clarify my question, suppose one has email organised in server X as described above, in directories ~/Maildir/Family/[cur.new.tmp/ , etc. And now suppose one wants to access this email from laptop Y. How exactly does one have to change the setup on machine X? And what does one set mail_location to? It seems to me that this is an issue likely to be faced by anyone wanting to run a small home network. reading email on various machines, and wanting this email to be kept "in sync". Maybe dovecot is not a suitable program for this purpose?

Wow! I'm running 1.1 Beta 1 on OpenSuSE linux 10.2. It seems not bad at all. The only thing I've not quite well understood is this message, that pops up when I start dovecot: Warning: fd limit 1024 is lower than what Dovecot can use under full load (more than 1536). Either grow the limit or change login_max_processes_count and max_mail_processes settings Where does dovecot take this 1024 fd limit?

[Dovecot] Deliver, sendmail & envelope From_
by Rich Winkel 25 Sep '07

25 Sep '07

Sorry, couldn't find this in the archives. Under freebsd 4.x, the native mail.local that sendmail uses by default writes From_ lines that include the origin address. This is very readily parsable and handy for quick greps in mboxes. But deliver defaults it to MAILER-DAEMON. I see you can specify the envelope From_ with "-f", but I'm not sure how that's useful. Also I'm trying to figure out the instructions for making deliver the default delivery program under sendmail. This is a very plain vanilla setup I have here, procmail is not configured into sendmail.cf so I'm not sure how to adapt the instructions at wiki.dovecot.org/LDA/Sendmail Any help would be much appreciated. I've appended my local mailer stuff below. Should I just substitute deliver's path for mail.local? By the way, dovecot is very slick! It should speed up my mail server by a huge factor. Many thanks to Timo!

[Dovecot] Unknown dict module: db
by Lars Stavholm 24 Sep '07

24 Sep '07

Using dovecot-1.1beta1 I get "Unknown dict module: db" when starting up dovecot. In dovecot.conf I've got the "expire_dict = db:/var/lib/dovecot/expire.db" statement in the plugin{} section. Aparently required when the "expire" plugin is enabled. dovecot is built with "--with-db" and db-devel is present at compile time. Any ideas anyone? Cheers /Lars

[Dovecot] deliver copies "^From " header lines when delivering to Maildir
by pod 24 Sep '07

24 Sep '07

deliver appears to copy "^From " header lines from stdin when delivering to Maildir. The header filtering in mbox-save.c prevents this when delivering to an mbox and instead a synthesized "^From " header is written. This is an issue when using, for example, Postfix and mailbox_command = /usr/libexec/dovecot/deliver which does not appear to have an option not to write a "^From " header on the mailbox_command input. I'm attaching a patch that adds a save_header_callback() along the same lines as in mbox-save.c but I'm really not sure this is the right way to do it.

[Dovecot] What is your dovecot setup?

I'd be really grateful if someone running a dovecot IMAP (or IMAPS) server could tell me exactly how their email folders are arranged. What is the mail_location setting in /etc/dovecot.conf ? What are the directories (or some of them) containing mail messages? Does the client see an inbox folder? If so, what directory on the server contains these email messages?

[Dovecot] SEARCH NOT not working
by Julian Cowley 24 Sep '07

24 Sep '07

I think I've found the source of a bug which I first saw when running dovecot and pine (or alpine), which I finally tracked down by doing a protocol trace. In the IMAP session, the SEARCH command appears to have a problem with sets of messages and/or the NOT operator. Probably the best way to show this is by doing operations on a folder with ten messages in it. a select ten * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 10 EXISTS * 0 RECENT * OK [UNSEEN 1] First unseen. * OK [UIDVALIDITY 1190450101] UIDs valid * OK [UIDNEXT 11] Predicted next UID a OK [READ-WRITE] Select completed. Now, start doing some basic searches using message sets: b search (1:10) * SEARCH 1 2 3 4 5 6 7 8 9 10 b OK Search completed. OK, so far so good. Try the inverse: c search not (1:10) * SEARCH c OK Search completed. OK. d search not (1,10) * SEARCH d OK Search completed. Hmm, should have output 2..9. e search not (2,10) * SEARCH 1 e OK Search completed. Hmm.. that should have been 1, 3..9. f search not (2:10) * SEARCH 1 f OK Search completed. OK, expected. g search not (1,9) * SEARCH 10 g OK Search completed. Seems to affect other end of the range as well. h search not (2,9) * SEARCH 1 3 4 5 6 7 8 10 h OK Search completed.

[Dovecot] dovecot with virtual and local users?
by Patrick Winnertz 23 Sep '07

23 Sep '07

Hello, I googled for a while in order to find a solution to make dovecot work with local and virtual users. My Mailserver setup looks like the following: virtual users are stored in a mysql database, and having their Mailbox here: /srv/mail/$domain/$uid/ Local users have a Maildir folder in their home directory. The only point i found in the web concerning this issue is this post here: http://www.dovecot.org/list/dovecot/2006-November/017478.html but I failed to understand the user_query. Can somebody who has such a setup running, or know how such a setup will work give me an advice, or a good point to read? Greetings Patrick ps: Please cc me, I'm not subscribed. -- .''`.

The next come from using the new Dovecot LDA: in trying to send mail, the following error occurs and I have not been able to find the setting to change this 2) postfix/qmgr[25767]: 2459A37F612: from=<from-email-address>, size=1226, nrcpt=1 (queue active) deliver(to-email-address): auth input: to-email-address deliver(to-email-address): auth input: uid=1000 deliver(to-email-address): auth input: gid=1000 deliver(to-email-address): auth input: home=path/to/ deliver(to-email-address): setgroups() failed: Operation not permitted postfix/pipe[6505]: 2459A37F612: to=<to-email-address>, relay=dovecot, delay=984, delays=984/0.03/0/0.06, dsn=4.3.0, status=deferred (temporary failure) The solution so far is to go back to using the Postfix Deliver option. Where is the setgroups option being set in the LDA? Thank for you hard work!! Jerry Yeager

[Dovecot] kmail + IMAPS
by Timothy Murphy 23 Sep '07

23 Sep '07

I have dovecot IMAPS + kmail working perfectly on two laptops - I'm using one now - but I just tried starting it on a third laptop, and cannot get it running; kmail on the third laptop just waits indefinitely, saying "Retrieving Folder Contents Please wait ...". All 3 laptops are running Fedora 7, with more or less the same packages, all updated. (1) I suspect the problem lies with authentication. But how can I test this? Running "telnet <server> 993" gets the same response on all 3 laptops: [tim@elizabeth ~]$ telnet www.*.com 993 Trying 86.*.*.228... Connected to www.*.com. Escape character is '^]'. with no further response until I press ^]. I looked at <http://wiki.dovecot.org/TestInstallation> but this seems only to apply to IMAP on port 143. (2) kmail has an option to "Check What the Server Supports" under the Security tag, but pressing this just returns without any message, leaving whatever settings as they are. (On the laptops where kmail is working as an IMAPS client, the settings are changed to "Use TLS ..." and "Clear text".) I realise this is probably a kmail question, but shouldn't clicking on this option return some warning if it does not work? (3) I guess I don't understand exactly how TLS authentication works. Does installing openssl set up the correct certificates on server and client? Is there any documentation on this? Any suggestions or enlightenment gratefully received.

[Dovecot] recipient delimiter results in sieve errors
by Gregory Mokhin 23 Sep '07

23 Sep '07

Hello, I'm using dovecot 1.0.3 and Dovecot Sieve plugin 1.0.2. Sieve script works fine with normal addresses, like user@domain.., and messages marked with "X-Spam-Flag: YES" are delivered directly to INBOX.Spam. To make deliver understand recipient_delimiter I tried two methods, the first one as per wiki (tweaking postfix master.cf), and the second one by tweaking dovecot-sql.conf (the main idea is to use concat(substring_index('%n',"+',1),'@','%d') for the username). Both methods work good. However when deliver processes sieve script for the addresses with a delimiter, user+ext(a)domain.tld, there is an error: deliver(test@k..): Info: cmusieve: Using sieve path: /home/vmail/.dovecot.sieve deliver(test@k..): Info: cmusieve: Executing script /home/vmail/.dovecot.sievec deliver(test@k..): Info: sieve runtime error: Keep: Generic Error deliver(test@k..): Error: sieve_execute_bytecode(/home/vmail/.dovecot.sievec) failed deliver(test@k..): Info: msgid=<..@mail...>: saved mail to INBOX In that case message is delivered to INBOX, not to INBOX.Spam Regards, Gregory

[Dovecot] Binary packagers: BSD license issues

Adding this SHA256 code made me read the BSD license once again. It says: * 2. Redistributions in binary form must reproduce the above copyright * notice, this list of conditions and the following disclaimer in the * documentation and/or other materials provided with the distribution. Then there are a few files from Cyrus as well which contain: * 4.

Currently these copyrights or acknowledgments aren't listed anywhere else than in the source files. I don't know if binary packagers have added those, but somehow I doubt it. So I think I should add these to COPYING file somehow. Any suggestions?

[Dovecot] IDLE with inotify problem
by Michael Guntsche 23 Sep '07

23 Sep '07

Hi, I recently switched from courier imap to dovecot. With courier I had a working IDLE setup that informed me immediately when new mail arrived. With Dovecot it is different, sometimes i get an immediate result but most of the time it takes a rather long time for the notification to return to the client. For testing purposes I set mailbox_idle_check_interval = 1 and i now get the same behaviour as with couier (a new mail immediately causes a notification) but i am not sure that this is the right solution. Reading the comments in the config files I was under the impression that this is not needed if dovecot uses inotify. Setup: Kernel 2.6.22.1 with inotify dovecot 1.0.3 from debian unstable Build options: ioloop=epoll notify=inotify ipv6 openssl So my question is can I check that dovecot is actually using inotify? Kind regards, Michael

[Dovecot] Problems with quota dict in 1.1.alpha4
by arvids 22 Sep '07

22 Sep '07

Hello, there are problems with quota dict when multiple dovecot deliver processes are launched in parallel. It can be reproduced by sending a mail with multiple different recipients - the mail is delivered OK to all recipients, but the quota are not updated correctly in sql. I looked at the code and it seems that the problem is somewhere in dict cache. If I configure in Postfix max number of deliver processes to 1, dict quota is updated correctly. postconf -n output: # 1.1.alpha4: /usr/local/dovecot/etc/dovecot.conf base_dir: /var/run/dovecot/ syslog_facility: local0 protocols: pop3 ssl_disable: yes disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/local/dovecot/libexec/dovecot/pop3-login login_greeting: Server. login_process_per_connection: no login_process_size: 64 verbose_proctitle: yes first_valid_uid: 95 first_valid_gid: 95 mail_uid: 95 mail_gid: 95 mail_location: maildir:~/Maildir mail_debug: yes fsync_disable: yes mail_executable: /usr/local/dovecot/libexec/dovecot/pop3 mail_plugins: quota mail_plugin_dir: /usr/local/dovecot/lib/dovecot/pop3 pop3_enable_last: yes pop3_client_workarounds: outlook-no-nuls oe-ns-eoh auth default: mechanisms: plain login digest-md5 cram-md5 apop cache_size: 2048 cache_ttl: 28800 cache_negative_ttl: 60 user: doveauth verbose: yes debug: yes debug_passwords: yes passdb: driver: sql args: /usr/local/dovecot/etc/dovecot-sql.conf userdb: driver: prefetch userdb: driver: sql args: /usr/local/dovecot/etc/dovecot-sql.conf socket: type: listen master: path: /var/run/dovecot/auth-master mode: 384 user: vmail group: vmail plugin: quota: dict:::proxy:/var/run/dovecot/dict-server:quotadict dict: quotadict: mysql:/usr/local/dovecot/etc/dovecot-sql-dict-quota.conf Regards, Arvids

[Dovecot] Feature Request for Proxy
by Ed W 22 Sep '07

22 Sep '07

Hi, Quick feature request for the proxy function: I have a couple of machines which are all customer facing and customer mailbox lives on any one of them. Customer can login to any machine and the proxy feature then forwards them to the correct machine (often the machine they are already connected to). However, right now if the SQL query simply returns the IP of the correct machine, and this happens to be the same machine that the connection is already on, then we get the auth process stuck in an infinite loop (and generating a lot of log files...) The quick fix is to customise each installation and add some kind of WHERE clause to change the results IF result is already the same as the machine we are on. However, this is error prone when setting up new machines and it's easy to forget or make a typo adjusting the config files. In my case I am using vservers and it's quite neat to be able to simply copy the whole image and fire it up on a new IP to test an upgrade, etc, hence easy to mess up adjusting the conf files when creating a new image. Any suggestions on how this could be done more dynamically, or else could I raise a feature request that the auth process somehow realises when it's being forwarded to an IP address that it's actually listening on already already (ie it's a request which loops back to itself), thus simplifying the config files? I haven't cracked open the code, but it sounds somewhat possible to check the list of IP addresses we are currently listening on and check that the proxy dest isn't among them? Cheers Ed W

[Dovecot] maildir rename_subfolders() and listescape interaction
by pod 22 Sep '07

22 Sep '07

I'd like to flag a problem we are observing that looks like it is caused by the listescape-plugin.c. I realize that this plugin is not part of the standard Dovecot 1.0 distribution but I would appreciate any insights or suggestions for fixes that anyone is kind enough to offer. The problem concerns subfolder renames when used in conjunction with Maildir folders (I've not tested this against any other folder type). Without listescape plugin: mail_location: maildir:%h/Maildir:INDEX=%h/index:CONTROL=%h/control mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota namespace: type: private separator: / inbox: yes 01 LIST "" * * LIST (\HasNoChildren) "/" "INBOX" 01 OK List completed. 02 CREATE a 02 OK Create completed. 03 CREATE a/b 03 OK Create completed. 04 LIST "" * * LIST (\HasChildren) "/" "a" * LIST (\HasNoChildren) "/" "INBOX" * LIST (\HasNoChildren) "/" "a/b" 04 OK List completed. 05 RENAME a c 05 OK Rename completed. 06 LIST "" * * LIST (\HasChildren) "/" "c" * LIST (\HasNoChildren) "/" "INBOX" * LIST (\HasNoChildren) "/" "c/b" 06 OK List completed. 07 LOGOUT * BYE Logging out 07 OK Logout completed.

Seemingly the only relevant log entry is @4000000046d70d8f1f72b66c dovecot: Error: IMAP(pod): rename(/srv/mail/home/test0/pod/Maildir/.a/b, /srv/mail/home/test0/pod/Maildir/.c/b) failed: No such file or directory Note the response to tag 05 in each case. The 06 list response in the listescape case is not unexpected given the nature of the failure. My initial reading of rename_subfolders() from maildir-storage.c suggests that the calls through maildir_mailbox_list_init() and maildir_mailbox_list_next() are returning "external" style names (i.e. ones that present "/" as the hierarchy separator) to rename_subfolders(), which is an "internal" helper function. This is supported by the logged error message. I am afraid I am yet to get my head around the actual code path and the escaping and unescaping that is going on so am not able to suggest a fix as yet.

[Dovecot] Multiple SSL certs
by Noah Kantrowitz 22 Sep '07

22 Sep '07

I am trying to find a way to have the SSL cert used by Dovecot be dependent on the local IP address. So far the only ways I have found is to either have two different instances running (annoying because I would need to argue with the init scripts a lot) or use the old, undocumented server{} sections. Is the latter an acceptable way to do this, or is there something better? --Noah Kantrowitz

[Dovecot] deliver assertion failure

Deliver from latest 1.1 HG with sieve also from latest 1.1 HG is dying with an assertion failure when it delivers to my mailbox.

[Dovecot] v1.1.alpha4 released / about dbox
by Timo Sirainen 22 Sep '07

22 Sep '07

http://dovecot.org/releases/1.1/alpha/dovecot-1.1.alpha4.tar.gz http://dovecot.org/releases/1.1/alpha/dovecot-1.1.alpha4.tar.gz.sig Lots of fixes since alpha3. Also includes the dbox rewrite. Currently dbox works properly only in one-message-per-file mode. I'm not actually even sure how good idea it would be to use it with multiple-messages-per-file mode. But I guess it won't hurt to finish its implementation and see. :) As you can see I haven't been replying much to the mailing list lately. My school started again, which meant that I had to start sleeping again at night instead of at day :) Doing that always takes a few weeks of feeling too tired to get much of anything done. Hopefully that goes away soon. A bit more about dbox: Originally I had thought that it'd be good to have multiple messages per file. The bad thing about that is that it works badly without fcntl locks, which don't work all that great with NFS. So I changed my plans a bit so that dbox also supports one-message-per-file behavior where it doesn't need locking much. (Multiple-messages-per-file is still supported by the format, but currently the code is not fully working.) dbox files begin with a header, then they have the message data and at the end of file there's a metadata block. Metadata contains things like message flags, keywords, received date and so on. When a flag/keyword is updated, the change is normally done only to index files. This is why dovecot.index and dovecot.index.log files are important with dbox format, they contain flag changes that haven't been written anywhere else. But since there's still a chance that index files could break (although v1.1 tries harder than v1.0 to fix problems), it would be nice if the flags/keywords were written to metadata block once in a while. So if the index files are lost, flag changes wouldn't be completely lost. Metadata updates of course use disk I/O so they shouldn't be done too often. I was thinking that the metadata could be updated: - if IMAP connection has been idling for 4 hours (not changing flags) - when closing mailbox and there are changes older than 4h - immediately if there are changes older than 24h (whenever mailbox is being synced, e.g. SELECT/NOOP/STATUS) Or something like that. Those rules can of course be changed, but I'm not sure if I should bother making them configurable from dovecot.conf. There are already too many settings.

[Dovecot] Unexpected input from auth master: CUID
by Branislav Baca 22 Sep '07

22 Sep '07

Hello, I'm using postfix(2.4.5) and dovecot(1.0.5), and till now I have been using postfix deliver agent. Now I have tried to reconfigure postfix to use the dovecot LDA, but I'm getting some strange error: Sep 9 18:07:57 hostname deliver(username(a)domain.tld): BUG: Unexpected input from auth master: CUID^I5 For IMAP and POP3 my configuration works fine. I have tried it also with dovecot versions 1.0.4 and 1.0.1, but the behaviour is the same. What can be the reason of this? What should I look for to get more details what can causing this? I have this line in postfix master file: dovecot unix - n n - - pipe flags=DRhu user=mails:mails argv=/opt/dovecot-1.0.5-1/libexec/dovecot/deliver -f ${sender} -d ${recipient} In main.cf: dovecot_destination_recipient_limit = 1 virtual_transport = dovecot Relevant parts of dovecot.conf: auth default { passdb sql { args = /path/to/dovecot-sql.conf } userdb sql { args = /path/to/dovecot-sql.conf } socket listen { client { path = /var/run/dovecot/auth-master mode = 0600 user = mails group = mails } } } protocol lda { postmaster_address = postmaster(a)domain.tld auth_socket_path = /var/run/dovecot/auth-master } And relevant parts of dovecot-sql.conf: driver = mysql password_query = SELECT address as user, passwd as password FROM mail_users WHERE address='%u' user_query = SELECT CONCAT('/home/',maildir) as home, 999 as uid, 999 as gid FROM mail_users WHERE address='%u' Thanks, BB

[Dovecot] Dovecot "authentication failed" interaction with Postfix
by Julian Cowley 22 Sep '07

22 Sep '07

Hi, I'm not sure if I should be posting this question here or on the Postfix mailing list, but I'll start here. When using Dovecot SASL with Postfix, is there a way to return a login-failed reason in the SMTP AUTH dialog using "nologin", similar to the way it can be done with Dovecot IMAP and POP? Details: I have a Dovecot authentication-only daemon working with a Postfix server doing SMTP AUTH. The Dovecot configuration uses a MySQL driver to get the password information, and one of the fields in the database is "access". In my SQL query, I return a row only if "access" is non-zero. This all works -- I can shut down an account from accessing mail while retaining the user's original password. password_query = SELECT username AS user, password FROM mailbox WHERE username = '%u' AND access != 0 Now, in my Dovecot IMAP and POP server configuration, I'm using "access" in a similar way, except that instead of not returning a row when "access" is zero, I return the "nologin" extra field (along with a "reason" field). The MySQL query for this is slightly tricky, but it works: password_query = SELECT username AS user, password, NULLIF(access != 0, 1) AS nologin, 'Access not allowed for this account' AS reason FROM mailbox WHERE username = '%u' While this second query works correctly with IMAP and POP authentication, it does not work with Postfix SMTP AUTH. Assuming the password is correct, the user is authenticated even when "access" is zero. It seems that either Postfix and/or dovecot-auth (I'm not sure which) is ignoring the "nologin" field in this case. In addition, when using the first SQL query, nothing is returned as a reason following Postfix's message. For example: AUTH PLAIN (correct password) 535 5.7.0 Error: authentication failed: <-- no reason returned here I'd like to return a reason here in the (optimistic :) hope that this will be shown to the user by the email client when an account is shut off. Here's an example of it working correctly with IMAP with an account that is shut off: 001 LOGIN user (correct password) 001 NO Access not allowed for this account

[Dovecot] Wrong size calculating with maildirquota
by Umut Arus 22 Sep '07

22 Sep '07

Hello, I'm using dovecot-1.0.5 with postfix. There is a problem which dovecot folder's size calculating wrong. It doesn't calculates whole folders' sum. Only maildirsize file keeps the first requested folder's size (in this example, Inbox). The example shows Inbox's size, another folder's size didn't add although connecting with IMAP. As the effect, I can not manage users' quota. Is there any hint with using namespace. Include quota size infos in control file, [root@xxxx Maildir]# cat /var/no-quotas/control/oneusername/maildirsize 512000000S 4941014 190 1849 1 40788 1 Also, namespace descriptions in dovecot.conf, namespace private { separator = / prefix = inbox = yes location = maildir:~/Maildir:INDEX=/var/no-quotas/index/%u:CONTROL=/var/no-quotas/control/%u } namespace private { separator = / prefix = mail/ #hidden = yes location = maildir:~/Maildir/.mail:INDEX=/var/no-quotas/index/%u:CONTROL=/var/no-quotas/control/%u } thanks in advance.

[Dovecot] Deliver parameter problem
by Umut Arus 22 Sep '07

22 Sep '07

Hello, I'm using dovecot-1.0.5 with postfix. I have to use deliver from procmail because I have some filters. There is no document about how to using deliver parameters (-d) other than http://wiki.dovecot.org/LDA . If I set -d parameters manually as a username everything is ok.

[Dovecot] Assertion failure in mail-index-view-sync.c
by Doug Council 22 Sep '07

22 Sep '07

I have been getting these assertion failures every couple days, killing the IMAP process. After it happens, I can login immediately and everything is fine until it happens again. Here is the log entry: Sep 10 10:03:41 mailbox-4 dovecot: nh: IMAP(username): file mail-index-view-sync.c: line 666 (mail_index_view_sync_end): assertion failed: (view->log_file_offset >= view->map->hdr.log_file_int_offset) Sep 10 10:03:41 mailbox-4 dovecot: child 38458 (imap) killed with signal 6 It started after I disabled indexing for deliver and IMAP: mail_location = maildir:~/Maildir:INDEX=MEMORY I removed the dovecot.index* files from all of the maildir directories (including the root/INBOX), but that didn't help. I have upgraded to 1.0.5, but that didn't help either. Any ideas as to what might be causing this? Thanks, -Doug

[Dovecot] dovecot 1.1alpha6 deliver+quota bugs
by Andrew Garner 22 Sep '07

22 Sep '07

I was playing around with dovecot-1.1 and maildir++ quotas, and ran into a reproducible error with indexing. This only seems to be a problem for new maildirs. If I send a message without the quota plugin on, and "seed" the index/control files, future deliveries with the quota plugin seem to succeed without errors.

[Dovecot] quota reporting and mail.app
by Mike Horwath 20 Sep '07

20 Sep '07

Hi everyone. I can't get mail.app to report back correct quota information using mail.app and dovecot (though it works with courier-imap). I am looking at migrating away from courier-imap to dovecot but this issue is something I need to have resolved <somehow>. Thunderbird is fine and reports back good info on either connection. I am off to read RFCs (can't I just read the sendmail book again? Might be easier...) to see what should really be done.

[Dovecot] SASL from remote server
by Daniel L. Miller 20 Sep '07

20 Sep '07

Is there a way, using Dovecot and Postfix, to use SASL from a remote server? Since it appears the communication uses Unix sockets, does this mean it is restricted to local services only? I have a two-server configuration, where my firewall also runs the mail gateway/filter (Postfix + ASSP). My internal server has Postfix + Dovecot. Right now I have my internal server configured to use Dovecot SASL, but the external server is still using the Courier authdaemon against the LDAP database. -- Daniel

[Dovecot] Running a script when a mail arrives
by Dennis Becker 20 Sep '07

20 Sep '07

Hi, I'm trying to execute a script when a mail arrives in a given user's mailbox. Something like .dovecot.sieve. The reason I'm not using sieve itself is that I need to do stuff on mail arrival, which is beyond sieve's features. So is there a way to tell dovecot to run a script when a mail arrives in a certain mailbox? Optionally a solution to forward the whole mail to a script would be good too. -- Dennis Becker

[Dovecot] Multiple Quota "ignore=" in Dovecot 1.0.x?
by Rich at Whidbey Telecom 20 Sep '07

20 Sep '07

Any chance that multiple "ignore=" statements cab be specified for a quota in Dovecot 1.0.x? We know this is possible in 1.1, but won't be able to update until it's stable. We've tried: quota = maildir:storage=256000:ignore=Junk:ignore=Trash and quota = maildir:storage=256000:ignore=Junk,Trash However, only "Junk" is ignored, and email can't be deleted when the mailbox is full. Thanks! Rich

[Dovecot] documentation for developers
by Boris Lorbeer 20 Sep '07

20 Sep '07

Hi there, I have two questions: - Is there a dovecot documentation for developers (apart from the source itself)? - In the site I am concerned with, it happens very often that one mail is delivered to hundreds of recipients. Since almost all of the mailboxes are situated on the same filesystem, the mail is delivered by just saving it once and establishing hardlinks from the mail directories of all the other recipients to this one mail. My question now is: can dovecot's lda "deliver" be configured to deliver mail to more than one recipients and to use the hardlink method just described? Boris -- Dipl. Phys.

[Dovecot] 'r' flag in ACL stomping on 'l' flag effect
by Phil Edwards 19 Sep '07

19 Sep '07

We're using Dovecot 1.0.3, and I'm setting up some shared IMAP folders. The eventual goal is to do the standard "learn as spam" / "learn as ham" type of setup, with some cron jobs to do the message extractions. But there's one minor twist: the "learn as ham" folder will need to be write-only for users. (I'll either create a fake user with read access to extract the mail for sa-learn, or do some local filesystem access, etc. A problem for a future day.) The issue is that some of the mail being misclassified might contain sensitive information. So users should be able to copy messages into that folder, but not list or read other messages. (Yes, they will be removed from the folder by the future sa-learn script, don't worry.) I can get normal operation with the ACL plugin and a global ACL file: # "TestTwo" mailbox acl file: authenticated lrwik * OK Dovecot ready. 1 login ........ 1 OK Logged in. 2 list "" * * LIST (\Noselect \HasChildren) "." "Testing/" * LIST (\HasNoChildren) "." "Testing/TestTwo" * LIST (\HasNoChildren) "." "Testing/TestOne" 2 OK List completed. 3 select "Testing/TestTwo" * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 0 EXISTS * 0 RECENT * OK [UIDVALIDITY 1189458953] UIDs valid * OK [UIDNEXT 1] Predicted next UID 3 OK [READ-WRITE] Select completed. Now, I change the TestTwo acl file to read authenticated lwik but can no longer subscribe to the folder: 1 login ........ 1 OK Logged in. 2 list "" * * LIST (\Noselect \HasChildren) "." "Testing/" * LIST (\HasNoChildren) "." "Testing/TestTwo" * LIST (\HasNoChildren) "." "Testing/TestOne" 2 OK List completed. 3 subscribe "Testing/TestTwo" 3 NO Permission denied According to http://wiki.dovecot.org/ACL, the 'l' flag means "Mailbox is visible in mailbox list. Mailbox can be subscribed to." but the second part of that statement is not actually happening. Is this a misunderstanding on my part, or a bug? -- Phil Edwards

[Dovecot] Delete mails in dovecot POP3 has a bug/feature
by Nuilte Infotech 19 Sep '07

19 Sep '07

When a mailbox has abt 40 mails with 4-5 mb attachments , it is quite common for the pop3 connection to get timed out or disconnected esp. if user has dialup modem. In this case , dovecot seems to REALLY HIT the user hard. Because it simply DOES NOT delete mails , even if user requested so. It only deletes the mails if users succesfully logs out. No other pop3 server has this problem so i would request this bugs is fixed ASAP. Effect of this bug - user has to retry multiple times and download multiple copies of mail before it finally deleted. Server Using ubuntu 7.04 Feisty Fawn + standard apt-get dovecot. Client end tested using getmail+BrokenUIDLPOP3Retriever To be Fixed - dovecot should delete mail even if the client connection gets "broken" or disconnects "ungracefully". e.g. user hits CTRL+C with getmail.

[Dovecot] What's the best way to authenticate against Active Directory?
by Chris Johnson 19 Sep '07

19 Sep '07

Hi all, I'm working on a replacement for a legacy linux mail server: courier POP/IMAP, Postfix, OpenLDAP. One of the requirements of the new mail server is to authenticate against our AD infrastructure (I'll still keep a userdb in OpenLDAP). SSO is not required since most of the clients don't log into our domain. The current system has about 1,000 concurrent users on it during the day (almost all are IMAP users). Inbox size varies but is generally very high 1GB+. I'm considering dovecot as a replacement for courier IMAP on the new server mainly for performance reasons. Cyrus was also considered but I'd rather work with maildir format inboxes. I'm in the process of installing a "proof of concept" server with CentOS 5 and dovecot-1.0-1.2.rc15.el5. the production system will most likely run on RHEL Question: What's the best way (most reliable/fastest) to authenticate dovecot to AD? If someone is doing this in a production environment can you offer any hints on configuration for performance or what to expect in general? Thanks, chrisj

[Dovecot] Dovecot 1.0.3: mbox problems for newly created users
by Bernd Kuhls 18 Sep '07

18 Sep '07

Hi, I am having problems with Dovecot 1.0.3 and Thunderbird 2.0.0.6 when using a new user account without any mbox files present. Directory /home/$user/.imap_mail/ does not exist when Thunderbird first tries to login using IMAP to the account. On login this directory is created with a zero byte Trash file and .subscriptions containing string "Trash", so far, so good. Now I create a new message in Thunderbird and save it as draft. A zero byte file "Drafts" is created in /home/$user/.imap_mail/ but the message I wanted to save got _lost_, /home/$user/.imap_mail/Drafts stays at zero bytes. The next message I try to save as draft finds its way to the Drafts mbox however. Please note that no /home/$user/.imap_mail/inbox has been created although a inbox is shown in Thunderbird. When I move the saved message from Drafts to the inbox folder shown in Thunderbird, it gets saved in /var/mail/$user instead of /home/$user/.imap_mail/inbox, I guess this is due to the use of the mbox_snarf plugin, right? /home/$user/.imap_mail/inbox is the maildrop for Exim, which handles incoming mails, but in this scenario the user did not receive any emails yet. If I manually create /home/$user/.imap_mail/inbox, then moving a message from Drafts to the Thunderbird-displayed inbox works. How to fix this problem? Especially messages getting lost is really bad because I am in the process of changing our mail server setup from Exim/UW-Imapd to Exim/Dovecot, where I have to move 100+ /var/mail/$user mbox files to /home/$user/.imap_mail/inbox. But when Dovecot can not properly save files to previous non-existing mbox files, like Drafts, this is really a problem.

[Dovecot] IP based virtual users: stripping login domain?
by Alan Ferrency 17 Sep '07

17 Sep '07

Hello. I have a likely unusual request regarding IP based virtual dovecot users. When you specify a passdb passwd-file name containing "%d", then the domain portion is stripped from the login username, before the user is checked in the passwd-file. However, if you specify a passwd-file name containing "%l" (the local IP), the domain portion of the login is not stripped off before the username is checked in the passwd-file. This behavior makes sense, and should be considered the right and proper thing to do. But in this case, I want to do something different anyway. In the setup I'm working on, most logins will use domain based virtual usernames. However, if a customer logs in with an unknown domain in their login username, I'd like to fall back to IP-based virtualization, based on the local IP they connect to. I can't use auth_username_format to strip off %d, because that would break the domain based virtualization. What I need is an option to make %l work the way %d already works; or a format inside a passwd-file which allows for partial matches in the "username" column. If I can do this directly using a passwd-file, I'd like to do that. It seems like it'd be easy if I were using an SQL back end, but that's not an option. It's possible with an external authentication script, but I want to explore more direct configuration options, first. Does anyone have any recommendations? If what I want can't already be done, and I patched dovecot to do one of these things, how likely would it be to have that patch merged into the project?

[Dovecot] Sent / Drafts / Trash folders and subscribing ?
by Xavier Beaudouin 17 Sep '07

17 Sep '07

Hello, I am trying to migrate our configuration that use Courier-imap to dovecot, appart some users that have some issues with pop and leave messages on servers that retreive all mails into their mailboes... but this is ok for me :).. One problem that it seems that Sent / Drafts and Trash folder are not automaticaly added as subscribed folder... I really dunno about IMAP rfc or standard, I just want to know if this is considered as normal for dovecot ? Thanks, /Xavier -- Xavier Beaudouin - http://oav.net/

[Dovecot] v1.1.alpha6 released
by Timo Sirainen 17 Sep '07

17 Sep '07

http://dovecot.org/releases/1.1/alpha/dovecot-1.1.alpha6.tar.gz http://dovecot.org/releases/1.1/alpha/dovecot-1.1.alpha6.tar.gz.sig Most importantly doesn't crash anymore if both pop3 and imap aren't used. :) I'm hoping people won't find anything too bad from this release anymore, so I'll release v1.1.beta1 in a week or so. I also finally did some larger API changes and code cleanups that I had been planning on doing for a long time. I also changed copyright notices in the code to: /* Copyright (c) xxxx-2007 Dovecot authors, see the included COPYING file */ So my name isn't there anymore. It wasn't always correct anyway. I'm planning on updating the -2007 year at the beginning of each year to all the files. It's annoying to try to keep it updated manually.

[Dovecot] Possible bug in authentication cache in dovecot 1.1.alpha4

[Dovecot] Dovecot stops talking to the auth server.
by Tom Diehl 17 Sep '07

17 Sep '07

Hi, I have an RHEL4 machine running dovecot-1.0.3 + postfix-2.3.2 + postfixadmin + mysql-4.1.20-2.RHEL4.1 + amavisd-new-2.5.2-1. The machine only has a gig of memory in it, I am trying to keep it running until I get new hardware to replace it in a couple of weeks. For the most part it works as advertised but every once in a while it stops talking to the auth server. I think I have tracked this to periods of high auth requests. Today the machine experienced a dictionary attack and I had log entries like the following: Sep 10 13:31:06 rocky dovecot: pop3-login: Disconnected: Shutting down: rip=::ffff:24.0.201.240, lip=::ffff:192.168.0.16 Sep 10 13:31:06 rocky dovecot: pop3-login: Can't connect to auth server at default: Resource temporarily unavailable Sep 10 13:31:07 rocky last message repeated 47 times Sep 10 13:31:08 rocky dovecot: pop3-login: Disconnected: Shutting down: rip=::ffff:24.0.201.240, lip=::ffff:192.168.0.16 Sep 10 13:31:08 rocky dovecot: imap-login: Can't connect to auth server at default: Resource temporarily unavailable Sep 10 13:31:08 rocky dovecot: pop3-login: Can't connect to auth server at default: Resource temporarily unavailable Sep 10 13:31:09 rocky last message repeated 27 times Sep 10 13:31:09 rocky dovecot: imap-login: Can't connect to auth server at default: Resource temporarily unavailable Sep 10 13:31:09 rocky dovecot: pop3-login: Can't connect to auth server at default: Resource temporarily unavailable Sep 10 13:31:09 rocky last message repeated 4 times Sep 10 13:31:09 rocky dovecot: imap-login: Can't connect to auth server at default: Resource temporarily unavailable ... a ps showed numerous defunct processes similar to the following: ... nobody 16647 0.0 0.2 9784 2112 ?

[Dovecot] Dovecot Sieve crash
by Julian Cowley 16 Sep '07

16 Sep '07

I just transferred the files in my home directory from an x86_64 machine to an i686 machine. This included the .dovecot.sieve and .dovecot.sievec files in my home root, and the Dovecot index files in my ~/Maildir directory. Everything seemed to be working until I tried sending an email that triggers a Sieve "redirect" command, then I got the following in the logs. I then tried the same dovecot.sieve file using a separate account which has always been on the i686 machine (and the index files have always been written there too), and the Sieve "redirect" worked fine. There were core files written in my home directory which I can post if necessary. Both the x86_64 and i686 machines are CentOS 4.5 running Dovecot 1.0.5 and Dovecot Sieve plugin 1.0.1.

[Dovecot] Migration woes from tpop mbox to dovecot maildir
by Chris Richardson 16 Sep '07

16 Sep '07

I was hoping some one might be able to offer me some advice on a little problem I have. I am looking to A. move from mbox to maildir B. looking to move from tpop to dovecot to bring both pop and imap under the same program. anyways the problem I am having is this tpop3d mbox uses MD5 sum of the mailbox headers in hex which is option %m in the uidl section but the problem is when dovecot convert plugin runs and makes in a maildir it fails to find the md5 of this because it is only used for mboxs. if I change this from %m to %Mf it downloads every message on the clients computer which is not desirable. I was thinking only options i have is to allow it to download all them mail and or write a script to convert it to maildir or another pop servers uidl. but i dont know much about how other pop servers generate there headers. so I was hoping maybe some one has done something similar to this or could offer some input. thanks -Chris The information transmitted is intended only for the person or entity to which it is addressed and may contain confidential and/or privileged material.

[Dovecot] v1.1.alpha5 released

http://dovecot.org/releases/1.1/alpha/dovecot-1.1.alpha5.tar.gz http://dovecot.org/releases/1.1/alpha/dovecot-1.1.alpha5.tar.gz.sig I think we're finally close to v1.1.betas. - Fixed "messages_count too large" index errors. - deliver was crashing. - Saving messages with maildir accessed freed memory, which might have caused crashes. - Index files are now never marked as "corrupted". Instead fsck is run which preserves as much of the original index as possible. This is important with dbox at least since index files are the only place where the latest flag/keyword changes are. Recent alphas were also modifying process's fd limits. The current behavior is: - If current fd limit is less than login_max_processes_count (imap +pop3) + max_mail_processes, log a warning at startup: "fd limit 1024 is lower than what Dovecot can use under full load (more than 1234). Either grow the limit or change login_max_processes_count and max_mail_processes settings" - Since 1024 is a common default limit, I dropped max_mail_processes default to 512. - Login processes drop their fd limit to the maximum number of fds needed, plus a few more just in case.

[Dovecot] Proxy problems with 1.0.5 !
by Ed W 15 Sep '07

15 Sep '07

Hi I am trying to do a staged migration over to dovecot, but having troubles at the first hurdle. I setup the proxy feature to redirect most of our users back to the current Courier imap/pop server, and it's partly working, but I'm getting some serious errors using Thunderbird and IMAP. Now, I had expected the proxying to be fairly transparent and basically just dovecot doing an auth and then passing the stream on to the other server? My problem is that using Thunderbird I can read all my folders OK, but I can't save anything in my Sent Items or Drafts folders... Basically I get errors every time I try and send an email, or try to save to the draft folder. Curiously, directly browsing into those folders works fine, as does deleting emails, and apparently copying them works fine also... Why is the saving of sent messages failing...? The setup is basically taking a working Thunderbird install, changing the server name from pointing at the Courier server to point at the dovecot server - dovecot in turn is told to proxy back to the original server. All I'm getting from Thunderbird is an "Invalid Command" response. Is there an easy way to get a look inside the imap stream to try and see what's failing? Any suggestions on why this is happening at all? One idea is that I have setup completely different namespaces in Dovecot, (with a hidden namespace which should be courier compatible), but I wouldn't have expected this to affect the Proxy stuff at all?! Grateful for any pointers to debug this - it's a fairly major hurdle for my rollout Thanks Ed W

[Dovecot] auth_default_realm for different listeners
by John Morrissey 15 Sep '07

15 Sep '07

We provide POP3 service for several realms, each of which has a substantial number of users logging in with no realm (bare username). We would like to use Dovecot, but I haven't been able to findout how to vary auth_default_realm for each listener. My most recent attempt was to set up one auth {} block for each realm with a different auth_default_realm and socket master path. I then set up one protocol pop3 {} block for each realm, listening on different IP addresses and with a auth_socket_path corresponding to the auth block for that listener. I'm not sure if I'm on the right track here, but I'm seeing two problems: 1. When dovecot starts, I get: Sep 5 18:32:21 pop01 dovecot: auth(otherdomain): Socket already exists: /var/run/dovecot/auth-otherdomain for each additional auth {} block. 2. dovecot won't start with auth_socket_path specified in a protocl pop3 {} block: Error in configuration file /etc/dovecot/dovecot.conf line 654: Unknown setting: socket_path Is there a way to vary auth_default_realm for each listener, so I can have multiple realms log in with bare usernames? thanks, john -- John Morrissey _o /\ ---- __o jwm(a)horde.net _-< \_ / \ ---- < \, www.horde.net/ __(_)/_(_)________/ \_______(_) /_(_)__

[Dovecot] namespace prefix issue with avelsieve
by it-dovecot＠ml.epigenomics.com 15 Sep '07

15 Sep '07

Hi! I am currently testing a setup with dovecot's lda, the cmusieve plugin, pysieved and the avelsieve plugin for squirrelmail. The issue I am stumbling upon is that avelsieve is generating folder names including the namespace prefix when creating "fileinto" rules. E.g.: A rule: If the header "Precedence" contains "bulk", then file it into the folder INBOX.bulk. Also keep a copy in INBOX, marked as deleted. translates into sieve: require ["fileinto","reject","vacation","imapflags","relational","comparator-i;ascii-numeric","regex","notify"]; if header :contains "Precedence" "bulk" { fileinto "INBOX.bulk"; addflag "\\Deleted"; keep; } But what happens when a matching email is delivered is that a new mailbox ".INBOX.bulk" in the user's Maildir is created. I.e. the email is not delivered to ~/.Maildir/.bulk as intended, but into ~/.Maildir/.INBOX.bulk, creating the new folder on the fly. The same happens when trying to fileinto folders from other namespaces. It seems that either avelsieve is generating "too much" and should remove the prefix (at least for INBOX) or dovecot's deliver is not able to use the namespaces definition in dovecot.conf correctly when interpreting sieve's fileinto directive. Did I miss something? This is the dovecot.conf in use: # /etc/dovecot/dovecot.conf log_timestamp: %Y-%m-%d %H:%M:%S listen: *:143 ssl_listen: *:993 ssl_cert_file: /etc/courier/imapd.pem ssl_key_file: /etc/courier/imapd.pem disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login login_processes_count: 12 login_max_processes_count: 512 verbose_proctitle: yes mail_location: maildir:~/.Maildir:INDEX=/var/cache/dovecot/INBOX.%u:CONTROL=/var/cache/dovecot/INBOX.%u mail_full_filesystem_access: yes maildir_stat_dirs: yes maildir_copy_with_hardlinks: yes namespace: type: private separator: . prefix: INBOX. inbox: yes namespace: type: public separator: . prefix: shared. location: maildir:~/.Maildir/shared:INDEX=/var/cache/dovecot/shared.%u:CONTROL=/var/cache/dovecot/shared.%u namespace: type: private separator: . prefix: archive. location: maildir:/mnt/nfs/imap_archive.hm/%u:INDEX=/var/cache/dovecot/archive.%u:CONTROL=/var/cache/dovecot/archive.%u auth default: verbose: yes passdb: driver: passwd userdb: driver: passwd socket: type: listen client: path: /var/run/dovecot/auth-client mode: 432 master: path: /var/run/dovecot/auth-master mode: 384 Greetings -- Robert Sander Senior Manager Information Systems Epigenomics AG Kleine Praesidentenstr. 1 10178 Berlin, Germany phone:+49-30-24345-0 fax:+49-30-24345-555 http://www.epigenomics.com robert.sander(a)epigenomics.com

Re: [Dovecot] Dovecot / OS X 10.4 Mail.app and "Too Many Opened files" error message ?
by Xavier Beaudouin 14 Sep '07

14 Sep '07

(replying to myself) > After a long time, the OS X client say error : "Too Many opened > files". Seems that OS X has stupidly low number of files that can be opened... $ ulimit -a [...] open files (-n) 256 On my MacBook Pro.... This is bloody low.... So I've figured to change this limit globaly, but it seems that OS X don't have any limits.conf or default values.... This kinda strange.. So I decided to do some local fixe for Mail.app only : in /Applications/Mail.app/Contents/MacOS/ $ sudo mv Mail Mail.orig and ... Create a Mail file with this following content : #!/bin/sh # thanks to http://www.amug.org/~glguerin/howto/More-open-files.html # To understand this, read 'man sh' below "substring processing". # This can also be accomplished with the 'dirname' command, # but it may not be installed. here="${0%/*}" # This should be the name of your native Java-app's executable. cmd='Mail.orig' # Set all desired soft-limits here. See 'ulimit' in 'man sh'. ulimit -S -n 1000 # Execute the Java-app in the current process. See 'exec' in 'man sh'. exec "$here/$cmd" "$@" $ sudo chmod +x Mail and this all... FYI Mail.app is really strange thing.... $ lsof | grep Mail.orig | wc -l 150 Mostly all libraries and TCP connection to mail server... Maybe this can be added to Wiki even if it is not too mutch dovecot related, but can be usefull for people like me that does have lots of mail.... /Xavier

[Dovecot] gssapi, kerberos and webmail
by Denis Cardon 14 Sep '07

14 Sep '07

Hi every one, first thanks for the great job, I switched successfully from courier imap a few months ago and both the migration and maintenance went smoothly from then on. The reason I switched was gssapi support (and the easier debug) and now I have thunderbird on Linux connecting in an SSO fashion through kerberos/GSSAPI (works great). Users should be able to access their mail throught a webmail too (eg. eGroupware). I have already checked for kerberos authentication on Apache, however there seems to be no way to have ticket forwarding throught PHP. AFIAK there is thus no way to use kerberos for php-imap --> dovecot authentication. The only information available seems to be the username. So here is my question : how do people on this mailing list handle kerberos authentication with webmail? Do you use other kind of authentication on privileged port (ie with access only from apache) and just do a login/nopassword authentication (like an uid base authentication through ldapi:/// on an ldap directory for example) ? Here is what we have with thunderbird : Thunderbird -------kerberos-------> dovecot on standard port Here is what I would guess for webmail auth : Firefox ------kerberos----> Apache ----gssapi-auth-just-using-login----> dovecot on privileges port Cheers, Denis -- Denis Cardon Tranquil IT Systems 44 bvd des pas enchantés 44230 Saint Sébastien sur Loire tel : +33 (0) 2.40.97.62.67 http://www.tranquil-it-systems.fr

Hello, I am trying to move from Courier-imap to dovecot.... Even if the processes to move logical (eg name spaces etc...) went very and without any problem, I've some etrange behavior when Imap client is Mac OS X Mail.app. I've got a big mailbox that have about 3 / 4G of mail in several folder (lots !!!)... After a long time, the OS X client say error : "Too Many opened files". I have check on the servers (a FreeBSD farm of 3 servers using freebsd ports of dovecot)... And nothing special... A question : why do I have never this kind of message on courier imap and why do I get this on dovecot... ? Configuration file on demand... if needed... THanks, /Xavier

[Dovecot] pipe() error but not linked to kqueue
by Patrick Milvich 14 Sep '07

14 Sep '07

I have dovecot 1.0.5 installed on an OpenBSD 4.1 box and an OS X Server 10.4.10 box. Sure you've all heard it before, because of the pipe error, no more login processes can be launched, and I have to restart the server. dovecot: Sep 13 05:50:00 Error: pipe() failed: Too many open files I first thought this was the issue with kqueue, but I've since recompiled making sure to use poll. This also happened with 1.0.3 and 1.0.2. It also happens very specifically after a dictionary attack that lasts usually about an hour, unless I can catch it earlier. (Around 18,000 login attempts) ex: dovecot: Sep 13 05:49:58 Info: pop3-login: Aborted login: user=<aaron>, method=PLAIN, rip=62.161.41.32, lip=<local ip> dovecot: Sep 13 05:49:58 Info: pop3-login: Aborted login: user=<adm>, method=PLAIN, rip=62.161.41.32, lip=<local ip> dovecot: Sep 13 05:49:58 Info: pop3-login: Aborted login: user=<account>, method=PLAIN, rip=62.161.41.32, lip=<local ip> But after the attack has subsided for a period of time, I still have the number of file descriptors maxed out for the dovecot process. I've increased the number available to have a higher roof, but that doesn't fix the problem. Wondering if anyone else has seen this issue, and also in a generic problem. How are others dealing the the problem of being attacked in this method? Is there a max number of login tries for a given ip address within a period of time that I'm missing? :) Thanks, Patrick

[Dovecot] dirsize quota assertion problem
by Alan Ferrency 14 Sep '07

14 Sep '07

Our current virtual mailbox configuration is not compatible with one of the assertions in the dovecot quota plugin's assertions in quota-dirsize.c. I believe the assertion is incorrect, but I would also be happy if I could get the same result with a better configuration setting. Here is a sample passdb entry which causes the quota assertion to fail: test(a)example.com:<snip>:3007:1000::/usr/boxes/username/example.com::userdb_mail=mbox:~/test^/.imap:INBOX=~/test userdb_uid=3007 userdb_gid=1000 userdb_home=/usr/boxes/username/example.com userdb_quota=dirsize:storage=100 The imap folder is "~/test^/.imap" and the INBOX is "~/test". As you can see, these are in different locations, but the INBOX string happens to be a substring of the imap folder directory. An example of the failed assertion error: Aug 31 16:44:13 www2 dovecot: IMAP(test(a)example.com): file quota-dirsize.c: line 180 (quota_count_path_add): assertion failed: (!is_file) This particular error log line was generated by dovecot 1.0.3, but the code in quota-dirsize.c is the same in dovecot 1.1 alpha3's version of quota-dirsize.c: 131 if (strncmp(count_path[i].path, path, strlen(path)) == 0) { 132 /* the new path contains the existing path */ 133 i_assert(!is_file); 134 count_path += i; 135 break; 136 } First, quota_count_path_add() is called for directory "~/test^/.imap" and it succeeds. When it is subsequently called for file "~/test": - the strncmp matches because "~/test" is a substring of "~/test^/.imap" - the assertion fails because "~/test" is a file and not a directory It seems to me that instead of asserting !is_file, it would be better to simply skip the conditional in that case, since a path variable that is a file should never be tested to see whether it contains an existing path. if (!is_file && strncmp(count_path[i].path, path, strlen(path)) == 0) { /* the new path contains the existing path */ count_path += i; break; } But this also has a bug: if path is a directory which substring matches count_path[i].path, but the same path with a directory separator appended to it does not substring match count_path[i].path, then it is a different path and does not contain the existing path. For example, if count_path[i] is the directory /usr/home/test/mailbox_folders, and path is the directory /usr/home/test/mailbox, then /usr/home/test/mailbox does not contain/usr/home/test/mailbox_folders, and this condition should fail. If some other code were to enforce that /usr/home/test/mailbox be terminated with a directory separator, then this is not a problem and my patch should work. I hope this makes sense.

[Dovecot] Dovecot + virtual users
by bichumo 13 Sep '07

13 Sep '07

Hi, I'm running FreeBSD, Dovecot, Postfix (virtual users), MySQL, Squirrelmail. I have installed squirrelmail-quota_usage-plugin, but I cannot make it work. It mentions "If you have an IMAP server with QUOTA Extension capability...". In dovecot.conf I have enabled "mail_plugins = quota" near protocol pop3 and protocol lda, near protocol imap I have "mail_plugins = quota imap_quota". Near " plugin { ..." I have "quota = maildir:storage=204800". I think that the problem of why I don't see quota in Squirrelmail is in file dovecot-sql near user_query. I have my users mailboxes in such format: /usr/local/virtual/domain.tld/username and my user_query looks like this: user_query = SELECT maildir, 125 AS uid, 125 AS gid, concat('maildir:storage=', quota) AS quota FROM mailbox WHERE username = '%u' AND active = '1', I think that in my user_query I'm missing something. I do not get any errors in the dovecot and dovecot-debug logs, everything works fine, but I still can't see quota.

[Dovecot] Datehandling bug?
by Ed W 12 Sep '07

12 Sep '07

Hi, I am testing dovecot 1.0.3 alongside my existing courier installation and a number of my emails are heading to the top of the inbox even though they are rather old. Closer inspection shows that my mailclient (Thunderbird on Win32) is showing me some screwey dates for a number of messages. One example is an email which says: Date: 2007-08-21 11:42:43 But in TB I see the date shown as only: 03:27 ie just a time and no date OK, the date above is clearly not an RFC date, but any idea why this is showing up only under Dovecot? Is it a dovecot date handling issue? Cheers Ed W

Dear list, I was trying to use the "notify" action with dovecot sieve but I just couldn't get it work.

[Dovecot] Deliver parameter problem
by Umut Arus 11 Sep '07

11 Sep '07

Hello, I'm using dovecot-1.0.5 with postfix. I have to use deliver from procmail because I have some filters. There is no document about how to using deliver parameters (-d) other than http://wiki.dovecot.org/LDA . If I set -d parameters manually as a username everything is ok. I can not set users' mail quota (don't lookup) with mysql db if I haven't set -d parameter as receipt username in procmail. How can I describe user (-d) parameter's variable in procmail? Procmail configuration, :0 | /usr/local/dovecot/libexec/dovecot/deliver -f $blabla -d $blabla2 Output of the configuration, # 1.0.5: /usr/local/dovecot/etc/dovecot.conf protocols: imap imaps pop3 pop3s listen: 10.1.1.168 ssl_cert_file: /usr/local/dovecot/etc/dovecot.cert.pem ssl_key_file: /usr/local/dovecot/etc/dovecot.key.pem disable_plaintext_auth: no login_dir: /usr/local/dovecot/var/run/dovecot/login login_executable(default): /usr/local/dovecot/libexec/dovecot/imap-login login_executable(imap): /usr/local/dovecot/libexec/dovecot/imap-login login_executable(pop3): /usr/local/dovecot/libexec/dovecot/pop3-login mail_location: maildir:%h/Maildir:INDEX=/var/no-quotas/index/%u:CONTROL=/var/no-quotas/control/%u mail_debug: yes mail_full_filesystem_access: yes mail_executable(default): /usr/local/dovecot/libexec/dovecot/imap mail_executable(imap): /usr/local/dovecot/libexec/dovecot/imap mail_executable(pop3): /usr/local/dovecot/libexec/dovecot/pop3 mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): mail_plugin_dir(default): /usr/local/dovecot/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/dovecot/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/dovecot/lib/dovecot/pop3 pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xv%08Xu namespace: type: private separator: / location: maildir:~/Maildir:INDEX=/var/no-quotas/index/%u:CONTROL=/var/no-quotas/control/%u inbox: yes namespace: type: private separator: / prefix: mail/ location: maildir:~/Maildir/.mail:INDEX=/var/no-quotas/index/%u:CONTROL=/var/no-quotas/control/%u auth default: verbose: yes debug: yes passdb: driver: pam userdb: driver: sql args: /usr/local/dovecot/etc/dovecot-sql.conf userdb: driver: prefetch socket: type: listen master: path: /var/run/dovecot/auth-master mode: 438 plugin: quota: maildir:storage=500000:ignore=trash regards,

[Dovecot] postfix + dspam + dovecot problem
by Lars Stavholm 11 Sep '07

11 Sep '07

Hi All, I'm new to dovecot (coming from cyrus) and have a bit of a problem setting up postfix + dspam + dovecot. 1. postfix + dovecot: works like a charm. Using "mailbox_command = /usr/lib/dovecot/deliver" in postfix main.cf 2. adding dspam to the equation: unable to deliver: net_connect(/usr/var/run/dovecot/auth-master) failed: No such file or directory Using "mailbox_transport = lmtp:unix:/var/tmp/dspam.sock" in postfix main.cf (instead of the above mailbox_command), and the corresponding setting in master.cf. In /etc/dspam.conf I'm using... TrustedDeliveryAgent "/usr/lib/dovecot/deliver" And here's the full error message: Sep 11 02:10:38 nwinnie postfix/pickup[18313]: 090F1C042: uid=0 from=<root> Sep 11 02:10:38 nwinnie postfix/cleanup[7010]: 090F1C042: message-id=<20070911001038.090F1C042(a)nwinnie.telcotec.se> Sep 11 02:10:38 nwinnie postfix/qmgr[18318]: 090F1C042: from=<root(a)nwinnie.telcotec.se>, size=431, nrcpt=1 (queue active) Sep 11 02:10:38 nwinnie deliver(stava(a)nwinnie.telcotec.se): net_connect(/usr/var/run/dovecot/auth-master) failed: No such file or directory Sep 11 02:10:38 nwinnie dspam[10379]: Delivery agent returned exit code 75: /usr/lib/dovecot/deliver -d stava(a)nwinnie.telcotec.se Sep 11 02:10:38 nwinnie postfix/lmtp[7018]: 090F1C042: to=<stava(a)nwinnie.telcotec.se>, orig_to=<stava>, relay=nwinnie.telcotec.se[/var/tmp/dspam.sock], delay=0.35, delays=0.32/0.01/0.01/0.01, dsn=4.3.0, status=deferred (host nwinnie.telcotec.se[/var/tmp/dspam.sock] said: 421 4.3.0 <stava(a)nwinnie.telcotec.se> Delivered (in reply to end of DATA command)) So, postfix hands the message to dspam, dspam does its thing, dspam tries to deliver and fails. What throws me is that the delivery works as expected in case 1) but not in case 2), despite the fact I'm using the same delivery agent, i.e. /usr/lib/dovecot/deliver. Why would dovecot go for some other authentication method in case 2)? BTW, we're using PAM on top of LDAP. Any ideas appreciated. Cheers /Lars

[Dovecot] Write-only mailboxes
by Steffen Kaiser 11 Sep '07

11 Sep '07

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, I've setup a mailbox for reporting SPAM by simply symlinking it into the Maildir of selected users. In order to preserve anonymity of the users I setup the mailbox as follows: drwxr-xr-t 5 root fb 4096 2007-09-05 16:18 ./ drwxr-xr-x 7 root root 4096 2007-09-05 16:16 ../ drwx-wx-wt 2 spamd fb 12288 2007-09-10 16:17 cur/ hence, with read permission for the spam bot only. When Thunderbird copies mails from the same mail account into the folder, it seems like it tries to select the mail box afterwards, then a "Internal error occured. Refer to server log for more information." because of permission denied. When one copies mail from yet another account into the SPAM box, no such message appears. I guess, Thunderbird does not try the refresh the message count. Well, is there a possiblity to setup a Write-Only mailbox, with Dovecot v1.0.3 with the ACL plugin? Is there a working setup for write-only mailboxes with the ACL plugin?

Thanks. That is a good point. Sounds like "login_processes_count=1" is the thing to do.
