[Dovecot] dovecot 1.1beta2 and dovecot-sieve 1.1.2 - crash in LDA

12 Oct '07

Hi, I've upgraded to dovecot 1.1beta2 and the latest dovecot-sieve release yesterday and have one single mail that cannot be delivered repeatedly.

[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] Quota Display with Horde / IMP ( WebMail Client )
by edwardspl＠ita.org.mo 11 Oct '07

11 Oct '07

Dear All, For the Dovecot.conf : protocol imap { mail_plugins = quota imap_quota mail_plugin_dir = /usr/lib/dovecot/imap } plugin { quota = maildir } For /var/spool/mail : -rw------- 1 root root 7168 Sep 24 23:02 aquota.group -rw------- 1 root root 8192 Sep 24 18:05 aquota.user -rw------- 1 edward mail 301709 Sep 24 23:27 edward But the Quota display is un-limited status... So, what mistake about the config ? Mine is FC6 System ! Thanks ! Edward.

[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
by James 10 Oct '07

Hi I know i might get flamed for asking this in the dovecot mailing list instead of the spamassassin one but i thought someone might be kind enough to help anyway.

[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] undelete messages?
by Cory Coager 08 Oct '07

08 Oct '07

I'm using the lazy expunge plugin as configured in: http://wiki.dovecot.org/Plugins/Lazyexpunge The page claims users can undelete messages without assistance from a sysadmin. How is this accomplished? When I try to subscribe to the folders under the EXPUNGED namespace, nothing happens. ~Cory Coager

[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] 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)
by Mike Brudenell 06 Oct '07

06 Oct '07

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? (I couldn't see anything in the Release Notes for either 1.0.4 or 1.0.5 about this) Cheers, Mike B-) -- The Computing Service, University of York, Heslington, York Yo10 5DD, UK Tel:+44-1904-433811 FAX:+44-1904-433740 * Unsolicited commercial e-mail is NOT welcome at this e-mail address. *

[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] Folder renaming oddities.

However, when the folders do not have an asterisk in the name. * LIST (\HasChildren) "." "Own Family" * LIST (\HasNoChildren) "." "Own Family.Maid" * LIST (\HasChildren) "."

P.S., Will it be possible to also request the mail-log plugin to log rename operations too? :) Thanking in advance. Cheers, Tan Shao Yi

[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.

I did find something new (or I have not noticed it before) If you kill (not just restart) the Dovecot process itself and restart it with existing connections (someone was connected to IMAPS when you killed Dovecot) Dovecot will not restart, complaining that port 993 is taken already.

[Dovecot] Thunderbird and imap alerts

Is Thunderbird supposed to show alerts sent via post-login scripts as in the wiki example? dovecot-imapd 1.0.5-1 (Debian) Thunderbird (Icedove) 2.0.0.4 (Debian) # dovecot -n|grep 'mail_executable(imap)' mail_executable(imap): /usr/local/sbin/dovecot-alert.sh # cat /usr/local/sbin/dovecot-alert.sh #!/bin/sh echo "* OK [ALERT] Hello World." exec /usr/lib/dovecot/imap Logging in with Thunderbird I get this alert: "Mail server imap.example.org is not an IMAP4 server". -- Thank you, Marco De Benedetto

[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] 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!

[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] Maildir ignore
by Tomas Horacek 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.

When I drag n drop spam mail to SPAM folder, I get this error: Jun 11 17:58:46 sparrow dspam[28452]: Unable to open file for reading: /var/spool/dspam/data/local/mymail/mymail.sig/466d652f315451306914567.sig: No such file or directory mymail is user that runs dovecot transport (postfix config).

[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
by Bill Landry 30 Sep '07

30 Sep '07

dovecot --version 1.1.beta1 With previous versions of Dovecot I could manually move maildir files between folders and the index would automatically update when entering the folder with Thunderbird. However, with 1.1.beta1, I am seeing the following when entering the folder, when attempting to rebuild the indexes via Thunderbird, or when attempting to force the download of all messages in the folder (this is with mail_debug = yes): Sep 30 09:05:55 mail dovecot: imap-login: Login: user=<bill(a)inetmsg.com>, method=PLAIN, rip=192.168.1.100, lip=192.168.1.37, TLS Sep 30 09:05:55 mail dovecot: IMAP(bill(a)inetmsg.com): Effective uid=1000, gid=1000, home=/var/spool/vmail/inetmsg.com/ Sep 30 09:05:55 mail dovecot: IMAP(bill(a)inetmsg.com): maildir: data=/var/spool/vmail/inetmsg.com/bill Sep 30 09:05:55 mail dovecot: IMAP(bill(a)inetmsg.com): maildir++: root=/var/spool/vmail/inetmsg.com/bill, index=, control=, inbox=/var/spool/vmail/inetmsg.com/bill Sep 30 09:05:58 mail dovecot: imap-login: Login: user=<bill(a)inetmsg.com>, method=PLAIN, rip=192.168.1.100, lip=192.168.1.37, TLS Sep 30 09:05:58 mail dovecot: IMAP(bill(a)inetmsg.com): Effective uid=1000, gid=1000, home=/var/spool/vmail/inetmsg.com/ Sep 30 09:05:58 mail dovecot: IMAP(bill(a)inetmsg.com): maildir: data=/var/spool/vmail/inetmsg.com/bill Sep 30 09:05:58 mail dovecot: IMAP(bill(a)inetmsg.com): maildir++: root=/var/spool/vmail/inetmsg.com/bill, index=, control=, inbox=/var/spool/vmail/inetmsg.com/bill Sep 30 09:05:58 mail dovecot: IMAP(bill(a)inetmsg.com): open(/var/spool/vmail/inetmsg.com/bill/.SURBL/cur/1190901367.M206487P27879V… failed: Permission denied Sep 30 09:05:58 mail dovecot: IMAP(bill(a)inetmsg.com): Disconnected: Internal error occurred.

[Dovecot] Log file name too with mail_log
by "Fábio M. Catunda" 30 Sep '07

30 Sep '07

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? Actualy this is what I get in logfile: dovecot: 2007-09-27 15:15:33 Info: IMAP(user(a)mydomain.com): copy -> Spam: uid=101, msgid=<46FBC6C9.1060301(a)somedomain.com>, box=Dovecot What I would like to have is something like: dovecot: 2007-09-27 15:15:33 Info: IMAP(catunda(a)mydomain.com): copy -> Spam: uid=101, file=/cur/1190916950.P15981Q38M976125.mydomain.com:2,S, box=Dovecot I believe that its a pretty simple thing to do, but my C skills are null! Any help would be great. Thankz! !DSPAM:46fc21ce213771244520847!

[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

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

Any major reason why this is so? Could I help implement it? Thanks in advance... -Abhijit

[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

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

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.

Either grow the limit or change login_max_processes_count and max_mail_processes settings Where does dovecot take this 1024 fd limit?
