[Dovecot] Caching?
by Bjørn T Johansen 13 Nov '07

13 Nov '07

Any way to minimize the number of sql statements that dovecot do? (and I tried adding userdb prefetch { } but number of sql calls are still the same) Am I doing something wrong or?

[Dovecot] v1.1.beta8 released
by Timo Sirainen 13 Nov '07

13 Nov '07

http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta8.tar.gz http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta8.tar.gz.sig Changes since beta7: - Added a new "raw" mail storage backend which allows opening files/streams as single mail mailboxes. deliver uses this now instead of opening the incoming mail as a mbox. So deliver should be now faster and it doesn't anymore remove Dovecot's private mbox headers if you're not using mbox. - Cache file tracks message expunges again - All kinds of other fixes - Some optimizations I think we're getting closer to v1.1 RCs.

[Dovecot] Missing deliver
by Sean Smitz 13 Nov '07

13 Nov '07

I've installed Red Hat Enterprise Linux 5 on a new server. I'm configuring sendmail and dovecot; however, /usr/local/libexec/dovecot was not created when I installed the dovecot rpm (rpm -Uvh dovecot-1.0-1.2.rc15.el5.x86_64.rpm). The problem is I can't find the deliver executable which is supposed to be in this directory. Any help would be appreciated.

[Dovecot] login_process_size too small on x86_64 Fedora/RHEL
by Tomas Janousek 12 Nov '07

12 Nov '07

Hello, as described in [253363], login_process_size of 32M is not enough on 64-bit versions of Fedora and RHEL (and possibly other distributions as well). [253363] https://bugzilla.redhat.com/show_bug.cgi?id=253363 As I understand it, there's an intersegment gap between read-only/executable and writable segments of shared libs. That's probably a security feature or something. I found a similar issue here[1], if anyone wants a comment from someone who understands it. [1] http://gcc.gnu.org/ml/libstdc++/2006-12/msg00033.html Shall we just increase login_process_size or make it arch-dependent or something? Regards, -- Tomas Janousek, SW Engineer, Red Hat, Inc.

[Dovecot] Secure authentication?
by Bjørn T Johansen 12 Nov '07

12 Nov '07

I have enabled SSL support for my dovecot installation but if I enable secure authentication in my MUA, I get an error from dovecot telling me that this is not supported.. Is this because dovecot does not support this or am I missing some config?

[Dovecot] dovecot 1.1b7: mail-cache-lookup.c: line 68: unreached
by Adam McDougall 12 Nov '07

12 Nov '07

I have since upgraded to 1.1b8 but this morning my attention was called to this error from 1.1b7: Nov 11 06:35:17 hill dovecot: IMAP(voice): file mail-cache-lookup.c: line 68: unreached Nov 11 06:35:17 hill dovecot: child 70673 (imap) killed with signal 6 Nov 11 06:35:17 hill dovecot: IMAP(voice): Connection closed bytes=262/25869 I can't say for sure but it was probably a squirrelmail connection. It wasn't me, and I wasn't even awake at the time so I don't know how to reproduce it.

[Dovecot] dovecot: pipe() failed: Too many open files
by Ralf Hildebrandt 12 Nov '07

12 Nov '07

I'm encountering lots of Oct 31 11:14:25 postamt dovecot: pipe() failed: Too many open files errors around midday ever since the latest upgrade to 1.0.7. The errors appear in pairs like this one: Oct 31 11:20:01 postamt dovecot: pipe() failed: Too many open files Oct 31 11:20:01 postamt dovecot: imap-login: Internal login failure: user=<username>, method=PLAIN, rip=193.175.174.239, lip=141.42.4.250, TLS What gives? -- Ralf Hildebrandt (Ralf.Hildebrandt(a)charite.de) plonk(a)charite.de Postfix - Einrichtung, Betrieb und Wartung Tel. +49 (0)30-450 570-155 http://www.arschkrebs.de We're using Postfix - it generally seems to take the approach that the message that arrives is the message that gets delivered, without any extra bits being added. -- Chris Stratford

[Dovecot] v2.0 / Master/config rewrite
by Timo Sirainen 12 Nov '07

12 Nov '07

If anyone's interested, I updated my master/config rewrite to latest Dovecot v1.1 tree and added it to hg: http://hg.dovecot.org/dovecot-master-rewrite/ It probably doesn't work, but with the exception of plugins it compiles anyway. :) I'm thinking that maybe after v1.1.0 I could continue with the rewrite and create v2.0 after all instead of v1.2. Just look at how much cleaner deliver.c is :) http://hg.dovecot.org/dovecot-master-rewrite/file/59ebbfcf21cb/src/deliver/… vs http://hg.dovecot.org/dovecot/file/eb4f1fbeecda/src/deliver/deliver.c Another thing with v2.0 I was thinking about was to change index file formats to be more efficient.

[Dovecot] some mail accesses in dovecot 1.1 stall for a bit (in progress)
by Adam McDougall 11 Nov '07

11 Nov '07

I noticed this in an earlier beta and took a note, and I still see it sometimes in 1.1b4, but it is only occasional so I have not tracked down yet what dovecot is doing. Just a FYI for the list incase others see it and to say that its an issue I tend to track down that I did not see in 1.0, and its been low on my list until now. Sometimes when I login to dovecot and read a message from an imap maildir folder, the message contents do not load for at least 10 seconds, sometimes closer to a minute, but after that first message loads, the rest seem fine in that mailbox. The time seems to vary some, usually longer rather than shorter.
