[Dovecot] IMAP Memory Error
by John McAree 25 May '05

25 May '05

Hi, I recently upgraded dovecot on an OpenBSD server from the 0.99.x series to the 1.0-test series to eliminate a problem. That was fixed, however I am now experiencing issues with IMAP(S) connections. The main IMAPS use to the server is via Squirrelmail (many users login with it), however I typically use Thunderbird. The user mailboxes are stored in Maildir format. Basically, moving, deleting or copying mails tends not to work. I have managed to move mails in Thunderbird if the source mailbox is small, and deleting mails usually works in Thunderbird. However, in Squirrelmail deleting or moving results in: "ERROR : Connection dropped by imap-server. Query: COPY 5629 "<dest-mailbox>" /var/log/maillog reports: May 24 23:19:03 orca dovecot: IMAP(jmcaree): pool_system_malloc(): Out of memory The Out of memory error appears when moving mails with Thunderbird, also. I had originally upgraded to dovecot1.0-test66 via a patch supplied by an OpenBSD porter. Today I decided to compile -test70 to see if it was any better. Unfortunately, this issue still exists. I tried upgrading Squirrelmail to the latest (1.4.4 from 1.4.3a), but no luck there. Since it's happening with both it and Thunderbird, though, I don't see it being a client issue. Server is: # uname -a OpenBSD my.hostname.com 3.7 GENERIC.RAID#0 amd64 I'd appreciate any assistance or advice on this issue! Obviously, I'd prefer to not have to downgrade to the 0.99.x series. :-) I'm not subscribed to the list, so please CC me with any replies. TIA, John.

[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

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 scoured t'internet and the closest I can find is this: http://dovecot.org/pipermail/dovecot/2005-February/006284.html Which got me past the "missing protocol from server" problem but hasn't got anywhere. 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).

[Dovecot] Info request
by Filip Cristian 23 May '05

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?
