[Dovecot] Auth Issue
by Adam Barrett 25 May '05

25 May '05

I am so confused. Can someone help me out here? I have set it up so that it is to accept login via PLAIN TEXT. I am using Thunderbird to connect, and it will ask for my password (the username is already in the system) I get a pop-up for Enter the password for Username on Domain.com I enter my password (the same I would use to login to FTP) and it fails. Any thoughts? -- Adam Barrett dragen(a)gmail.com

[Dovecot] Simply can't figure it out
by Gaby vanhegan 24 May '05

24 May '05

Hi, I'm having a hideous problem trying to get the latest stable version to work. I've had no success and simply can't pinpoint the problem. Sorry for the rather long email but I've included as many details as I can to help here. I've been trying to install the latest stable version (as of 23rd May 2005) by downloading the tarball from the site to my OpenBSD 3.6 box, and building with these arguments: # ./configure --localstatedir=/var --with-ssl=openssl --with-ssldir=/etc/ssl --without-vpopmail - -without-pam --without-shadow Which builds fine. Here are some files from the installation folder: http://vanhegan.net/dovecot/config.log http://vanhegan.net/dovecot/config.status Here's my configuration file. I only really want to server imaps, but I've turned on imap for debuggering purposes: http://vanhegan.net/dovecot/dovecot.conf And it's running from my inetd.conf: # Dovecot IMAP services 144 stream tcp nowait root /usr/local/libexec/dovecot/imap-login imap-login --group=default/imap imaps stream tcp nowait root /usr/local/libexec/dovecot/imap-login imap-login --group=default/imap --ssl (I'm running on port 144 to not clash with the existing IMAP service on port 143). Now, no matter what I try, I simply can't make it login, or start the process: (restart inetd, dovecot, check they're dead) bash-3.00# kill -HUP `cat /var/run/inetd.pid` bash-3.00# kill -TERM `cat /var/run/dovecot/master.pid` bash-3.00# ps auwx | grep dove root 828 0.0 0.1 84 456 p2 S+ 8:39PM 0:00.01 grep dove bash-3.00# /usr/local/libexec/dovecot/imap-login --group=default/imap F/usr/local/libexec/dovecot/imap-login can be started only through dovecot master process, inetd or equilevant (start dovecot, check it's running, error expected, other imap server already running) bash-3.00# /usr/local/sbin/dovecot Fatal: listen(143) failed: Address already in use bash-3.00# ps auwx | grep dove root 14041 0.0 0.3 212 1012 ??

I've since fallen back to the version in ports from OpenBSD 3.6 but really want to get this going. Any ideas?

[Dovecot] Newbie-ish Questions
by Joe Dauncey 24 May '05

24 May '05

Hi, I'm in the process of migrating from local Maildir, to IMAP-enabled Maildir (terms are made up by me). I have my Maildir directories all under $HOME/Mail I have a procmail script that sorts everything into different folders under $HOME/Mail, and leaves the rest in a Maildir folder chosen by me, that I think of as my INBOX. Now, I am assuming that the folder I identify as INBOX is the one that a client will interpret as the INBOX? I really want the INBOX to be one of the folders under $HOME/Mail, but at the moment dovecot only will only consider the folder $HOME/Mail as the INBOX, so I have to send my 'inbox' mail to $HOME/Mail, rather than what I would prefer, which would be $HOME/Mail/INBOX (or something like that). The seting I have in dovecot.conf is: default_mail_env = maildir:~/Mail Is this is the only way, or am I doing something wrong? Should I be using default_mail_env to define the inbox? e.g. with: default_mail_env = maildir:~/Mail:INBOX=INBOX (or whatever my inbox mail folder name is) Maybe I've just got my Maildir folder set up completely wrong, and I'm supposed to accept the Maildir folder itself as the inbox? If so, please just send me on my way ;-) Also, since I don't know much about IMAP, where can I find out what the .subscriptions file is, and what it does, and also all the other files created by dovecot, like the .imap files and the .customflags Thanks, Joe -- Joe Dauncey

[Dovecot] Read-only mail folders
by Chris Wakelin 24 May '05

24 May '05

Is it possible to have folders on read-only partitions in Dovecot 1.0-stable? We have a NetApp fileserver which would probably be accessed via NFS (though iSCSI is possible) and which stores readonly "snapshots" of every directory accessible as .snapshot (but usually hidden from the operating system). It would be very nice to set up a "snapshot" namespace something like :- namespace public { separator = / prefix = "#snapshot/" location = maildir:%h/Maildir/.snapshot/nightly.0 hidden = yes } so that users could recover messages from say yesterday's version of their mailbox. Unfortunately, Dovecot always seems to want to write to the directory, even when indexes are stored elsewhere (as recommended with NFS anyway, I think) using INDEX=whatever in the location line.

[Dovecot] Stability
by Casey Allen Shobe 24 May '05

24 May '05

I am currently using Dovecot 0.99.14-r1 as provided by Gentoo, in a Qmail + VPopmail configuration. I am curious as to how to configure it to ensure the most stability, as it serves >1000 clients. I would rather disable any indexing that give small speed improvements if they are not known to be stable. Advice?

[Dovecot] 1.0-stable loses flag changes sometimes?
by Chris Wakelin 24 May '05

24 May '05

I've been struggling with an odd bug in the latest 1.0-stable (20050427) release. Sometimes Dovecot seems to forget that a message has been read or deleted and marks it unread (or not deleted). As far as I've been able to determine, it seems to happen when 1) There have been several recent deliveries 2) Possibly some of those deliveries are of multiple messages 3) Possibly they are read very quickly (say only a second for each message) 4) Folder is an mbox (haven't tried Maildir) I've seen it with Thunderbird mostly, but did manage to recreate it once in "telnet" - the debug IMAP client ;) - using "IDLE" "FETCH" and "STORE msgid +FLAGS (\Seen)" commands. I managed to catch it in the act with one Thunderbird session, and it seemed to occur when Thunderbird, for some reason, issued an IMAP "CHECK" command. In this case it issued an extra "* 710 FETCH (FLAGS (\Recent))" response (the new messages had been msgid 711-715). Incidentally, Thunderbird seems to do a "STORE .. +FLAGS (\Seen)" command even though this is implicit the "FETCH .. BODY[..]" command (and it gets informed of the flag change in the response). I've tried and tried to find a "formula" for re-creating the problem "on demand", but it only goes wrong occassionaly. My guess is it's some sort of timing thing with mbox sync (BTW we have "mbox_dirty_syncs = yes" and "mbox_very_dirty_syncs = no"). Has anybody else seen this? I'm hoping to roll out this version to our wider group of testers soon and would like to get this issue solved first if possible (it counts as an annoyance rather than a serious problem).

Hello, I'am Filip Cristian System Administrator at Astral Telecom and i'am using on our email servers dovecot for pop*, imap* auth with mysql suport. I have noticed that in the 1.0-test* release you have support for multiple password databases. From what i have tested this it's working but only if you want to fallback to another supported password databases different that the privios. Is there a posibility to use multiple mysql authentication ? I mean to use two or more mysql hosts on wich to connect and search for the username if the user it's not in the first database?

[Dovecot] utime() failed: Value too large for defined data type
by Brian Hechinger 22 May '05

22 May '05

i have recently rebuilt dovecot on my mail server as i wanted to add SSL support for it. well, my OpenSSL libs are 64-bit, so what they hey, i'll build dovecot 64-bit as well. worked just fine, no issues at all. the setup is: Solaris 9/SPARC Sun C compiler Dovecot 0.99.14 after rebuilding it 64-bit, i now have a small problem however. I cannot save messages to IMAP folders from Mail.app on OSX 10.3.9. OE6 and mutt work fine, no problems there, but when I try to save a message from Mail.app, it tells me it couldn't save the message and i get the folloing in my log file on the mail server: May 19 16:24:37 wiggum.4amlunch.net imap(paula): [ID 702911 mail.error] utime() failed for /usr/home/paula/Maildir/.Sent Items/tmp/1116534277.P10885Q0M105223.wiggum.4amlunch.net: Value too large for defined data type does anyone have any clue as to what could be the cause of this? i would say simple 64-bit uncleanliness issue, but why doesn't it also affect OE6 or mutt? there is some way that Mail.app accesses IMAP that is specifically tickling this problem. thank you very much for your time, and if there is any other information you might need to track this down, please ask and i'll get it right away. -brian -- "I fear death only slightly more than I hate my life." --8-bit Theater

[Dovecot] Corrupted transaction log file, dotlocks..?
by John and Catherine Allen 16 May '05

16 May '05

I'm new to Dovecot but I've been able to get it up and running on a test basis without too much difficulty. I'm running dovecot-stable-20050508 with maildir, under Linux (an old Gentoo setup that's been stable for about 2,5 years). Mail client is Thunderbird. However, in the course of experimentally copying the accumulated household email (95000 emails from the last 10 years) from the existing IMAP server (UW-IMAP) using imapsync, I'm seeing some problems. While copying the 1000 or so messages from the main INBOX, Dovecot seems to hang after 50-100 messages and the following lines appear in the server log: May 15 18:45:21 [dovecot] IMAP(allen): utime(/home/allen/Maildir/dovecot-uidlist.lock) failed: No such file or directory May 15 18:45:21 [dovecot] IMAP(allen): Our dotlock file /home/allen/Maildir/dovecot-uidlist.lock was deleted May 15 18:45:21 [dovecot] IMAP(allen): Corrupted transaction log file /home/allen/Maildir/dovecot.index.log: Append with UID 1827, but next_uid = 1828 May 15 18:45:21 [dovecot] IMAP(allen): Lost transaction log file /home/allen/Maildir/dovecot.index.log seq 4 May 15 18:45:21 [dovecot] IMAP(allen): Lost transaction log file /home/allen/Maildir/dovecot.index.log seq 4 May 15 18:45:21 [dovecot] IMAP(allen): Corrupted transaction log file /home/allen/Maildir/dovecot.index.log: Append with UID 1827, but next_uid = 1828 May 15 18:45:21 [dovecot] IMAP(allen): Lost transaction log file /home/allen/Maildir/dovecot.index.log seq 4 [...20 identical lines deleted....] May 15 18:48:27 [dovecot] imap-login: Login: allen [192.168.0.1] May 15 18:48:57 [dovecot] imap-login: Login: allen [192.168.0.1] May 15 18:48:57 [dovecot] IMAP(allen): Transaction log file /home/allen/Maildir/dovecot.index.log: marked corrupted I can restart after deleting the dovecot files in ~/Maildir, but the problem recurs.

[Dovecot] new-attrib lost when calling through pop3
by Marten Lehmann 15 May '05

15 May '05

Hi, I noticed, that all messages are moved from new/ to cur/ (using maildirs) after the authentication in pop3, even before the list command. I'm working with 1.0-stable-20050426. Why is this done? Shouldn't a message keep it's new-attrib as long as it isn't retrieved? This is how it worked with qmail-pop3d. Through imap, it works correctly. It's just sad if I can't distinguish between older and new emails with imap, just because I logged in through pop3 shortly before. Regards Marten

[Dovecot] fcntl lock timout on maildir format Trash .index file under OpenBSD sparc64
by Dale J. Robertson 15 May '05

15 May '05

Whenever I attempt to retrieve or delete mail (Using thunderbird win client) operation takes several minutes. right before completion posts the following error to maillog: May 14 10:22:04 NAPUtil imap(djrobert): Timeout while waiting for release of shared fcntl() lock for index file /home/djrobert/Maildir/.Trash/.imap.index deleting the index file speeds up the operation once. subsequent operations are slow again I don't know what other process is placing a lock on the file. or how to clear it. I am running the 9914p0 package distributed with a march 11 3.7 snapshot (OS loaded from the same snapshot). I previously was running the release 3.6 OS and the Dovecot package that came with the CD. both installs exhibit the same behavior. Both Dovecot and postfix are configured with fcntl locking only. What the heck am I doing wrong? Thanks, Dale

[Dovecot] dovecot through NFS
by Marten Lehmann 14 May '05

14 May '05

Hello, as our mail server load increases every day, I plan to scale the single mailserver in differnt units: 1x big storage server for all mailboxes, folders exported through NFS 1x smtp for mail-in (queue local, messages on storage server) 1x pop3/imap to retrieve the messages (config local, messages on storage server) Since we're using maildir only, there's no problem to get the messages into the mailboxes. But what about dovecot for retrieving them? NFS will be v3. Is locking still a problem with it? Might the indexes get corrupt? Regards Marten

[Dovecot] Fedora Core 3 and Mail.app problems
by Gordon Turner 14 May '05

14 May '05

Hello, first thanks for all the work, I appreciate the attention to security :-) I have a performance issue I am trying to solve. On my new server it would appear that synchronizing changes between the client and server is taking longer then my previous setup. I have recently upgraded from my old server to a new home (the basis for my comparison), From: - Redhat 9.0, uw-imap, using self-signed ssl certificates, on an old p-II. - Only one email user (me), about 40 mail folders with a few dozen messages in each. - Performance was never an issue, Mail.app took maybe 20 seconds to sync up minor deletes etc. To a new home: - Clean install of Fedora Core 3 on a p4, dovecot-0.99.13-3.FC3. - Copy of /home/gturner/mail directory to new server, ie existing mbox format from uw-imap. - Recreated new self-signed certificates on new server, manually added the self-signed certificates, connected with no problems. - Mail.app client, on OS X 10.3.9 (no Tiger yet). I deleted the account on Mail.app, and created it again, the first login/sync took a long time, which was expected. However after that, I noticed that when I first connect or delete a file the sync is slower then the old setup (FYI, I keep "Automatically synchronize changed mailboxes" checked on Mail.app). A result of this appears to be some corruption of some mailboxes, only one or two, nothing valuable. For example, I delete a file and then clear the trash while things are still syncing. So my current solution is to be patient. :-) Any suggestions? I know that I could covert everything over to maildir, but I would like some feedback to see if this would be reasonable. I also noticed that initially there are 3 'gturner imap' threads and the syncing seems to be flying along. Then the thread count goes to 5 or 6 and sync starts to crawl. I looked for a way to limit the number of spawned threads, but only saw stuff about 'waiting' threads or reference to 1.0. I have attached my dovecot.conf for reference. Any help is greatly appreciated, Gord Turner.
