[Dovecot] My status
by Timo Sirainen 23 Jul '11

23 Jul '11

Hello list, In case anyone's wondering why I haven't been replying here much lately: 1. I've been busy working (you know, paid work) on full text search indexing redesign. That change was a bigger job than I realized at first (mainly due to virtual mailboxes), so I've been a bit stressed/frustrated over it. I finally finished it today though, so that's over now: http://hg.dovecot.org/dovecot-2.1/rev/7b9978eb6f91 I hope to add Antonio's Solr attachment indexing support to it once I'm a bit less busy. I'm in any case also going to add generic attachment indexing so that CLucene backend can also do it. I've also other work left to do for a few more weeks. 2. My new apartment gets too hot (30C) when it gets over about 22C outside, which is almost daily. So my brain melts in the heat and I don't have energy to do much of anything. But I finally yesterday bought an air conditioning machine, which should solve this problem. I don't know why I didn't buy it weeks ago. So .. I'll try to get back to reading and answering mails next week after I've finished some more work and don't feel like I'm lagging behind too much.

[Dovecot] failed creating protocol instance to play queued url
by Ken Mandelberg 22 Jul '11

22 Jul '11

I run thunderbird (both 3.x and 5.x) against dovecot 2.x and frequently see delays "loading message". I admit to having a very large mailbox and running multiple imap clients. I've turned on thunderbird debugging, and at least one pattern I see in the log during the delays (maybe a minute long) is the failed protocol message above. These are no the only delays, but are the ones that catch my eye. The thunderbird debug logs are not time stamped (that I can tell), so its difficult to go back and find the delays from the log. Here is an example of one of the delays. Any thought? -1215891312[b760f060]: considering playing queued url:imap://km@mailhost.mathcs.emory.edu:993/addmsgflags>UID>/INBOX>134829>1 -1215891312[b760f060]: creating protocol instance to play queued url:imap://km@mailhost.mathcs.emory.edu:993/addmsgflags>UID>/INBOX>134829>1 -1215891312[b760f060]: failed creating protocol instance to play queued url:imap://km@mailhost.mathcs.emory.edu:993/addmsgflags>UID>/INBOX>134829>1 80784240[8db84f80]: ImapThreadMainLoop leaving [this=8f345000] a Minute or so delay -1675625616[8e59a5b0]: ReadNextLine [stream=8e5049c8 nb=153 needmore=0] -1675625616[8e59a5b0]: 9023c800:mailhost.mathcs.emory.edu:A:CreateNewLineFromSocket: * FLAGS (\Answered \Flagged \Deleted \Seen \Draft NonJunk $notjunk $Forwarded $label1 $MDNSent junk $junk $label3 junkrecorded $label4 $label2 $label5) -1675625616[8e59a5b0]: ReadNextLine [stream=8e5049c8 nb=187 needmore=0] -1675625616[8e59a5b0]: 9023c800:mailhost.mathcs.emory.edu:A:CreateNewLineFromSocket: * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft NonJunk $notjunk $Forwarded $label1 $MDNSent junk $junk $label3 junkrecorded $label4 $label2 $label5 \*)] Flags permitted. -1675625616[8e59a5b0]: ReadNextLine [stream=8e5049c8 nb=16 needmore=0] -1675625616[8e59a5b0]: 9023c800:mailhost.mathcs.emory.edu:A:CreateNewLineFromSocket: * 60229 EXISTS -1675625616[8e59a5b0]: ReadNextLine [stream=8e5049c8 nb=12 needmore=0] -1675625616[8e59a5b0]: 9023c800:mailhost.mathcs.emory.edu:A:CreateNewLineFromSocket: * 0 RECENT -1675625616[8e59a5b0]: ReadNextLine [stream=8e5049c8 nb=35 needmore=0] -1675625616[8e59a5b0]: 9023c800:mailhost.mathcs.emory.edu:A:CreateNewLineFromSocket: * OK [UNSEEN 60218] First unseen. -1675625616[8e59a5b0]: ReadNextLine [stream=8e5049c8 nb=42 needmore=0] -1675625616[8e59a5b0]: 9023c800:mailhost.mathcs.emory.edu:A:CreateNewLineFromSocket: * OK [UIDVALIDITY 1287420195] UIDs valid -1675625616[8e59a5b0]: ReadNextLine [stream=8e5049c8 nb=42 needmore=0] -1675625616[8e59a5b0]: 9023c800:mailhost.mathcs.emory.edu:A:CreateNewLineFromSocket: * OK [UIDNEXT 134841] Predicted next UID -1675625616[8e59a5b0]: ReadNextLine [stream=8e5049c8 nb=36 needmore=0] -1675625616[8e59a5b0]: 9023c800:mailhost.mathcs.emory.edu:A:CreateNewLineFromSocket: * OK [HIGHESTMODSEQ 16298] Highest -1675625616[8e59a5b0]: ReadNextLine [stream=8e5049c8 nb=37 needmore=0] -1675625616[8e59a5b0]: 9023c800:mailhost.mathcs.emory.edu:A:CreateNewLineFromSocket: 4 OK [READ-WRITE] Select completed. -1675625616[8e59a5b0]: 9023c800:mailhost.mathcs.emory.edu:S-INBOX:SendData: 5 UID fetch 134841:* (FLAGS) -1675625616[8e59a5b0]: ReadNextLine [stream=8e5049c8 nb=44 needmore=0] -1675625616[8e59a5b0]: 9023c800:mailhost.mathcs.emory.edu:S-INBOX:CreateNewLineFromSocket: * 60229 FETCH (UID 134840 FLAGS (NonJunk)) -1675625616[8e59a5b0]: ReadNextLine [stream=8e5049c8 nb=23 needmore=0] -1675625616[8e59a5b0]: 9023c800:mailhost.mathcs.emory.edu:S-INBOX:CreateNewLineFromSocket: 5 OK Fetch completed. -1675625616[8e59a5b0]: 9023c800:mailhost.mathcs.emory.edu:S-INBOX:SendData: 6 UID fetch 134829 (UID RFC822.SIZE BODY[]) -1675625616[8e59a5b0]: ReadNextLine [stream=8e5049c8 nb=82 needmore=0] -1675625616[8e59a5b0]: 9023c800:mailhost.mathcs.emory.edu:S-INBOX:CreateNewLineFromSocket: * 60218 FETCH (UID 134829 RFC822.SIZE 16236 FLAGS (\Seen NonJunk) BODY[] {16236} -1675625616[8e59a5b0]: 9023c800:mailhost.mathcs.emory.edu:S-INBOX:STREAM:OPEN Size: 16236: Begin Message Download Stream -1675625616[8e59a5b0]: ReadNextLine [stream=8e5049c8 nb=50 needmore=0] -1675625616[8e59a5b0]: 9023c800:mailhost.mathcs.emory.edu:S-INBOX:CreateNewLineFromSocket: Return-Path: <sunray-users-bounces(a)filibeto.org> -1675625616[8e59a5b0]: ReadNextLine [stream=8e5049c8 nb=68 needmore=0] -1675625616[8e59a5b0]: 9023c800:mailhost.mathcs.emory.edu:S-INBOX:CreateNewLineFromSocket: Received: from mr5.cc.emory.edu (mr5.cc.emory.edu [170.140.52.94]) -1675625616[8e59a5b0]: ReadNextLine [stream=8e5049c8 nb=77 needmore=0] -1675625616[8e59a5b0]: 9023c800:mailhost.mathcs.emory.edu:S-INBOX:CreateNewLineFromSocket: by cssun.mathcs.emory.edu (8.13.8+Sun/8.13.8) with ESMTP id p6IMb4KL014274 -1675625616[8e59a5b0]: ReadNextLine [stream=8e5049c8 nb=67 needmore=0] -1675625616[8e59a5b0]: 9023c800:mailhost.mathcs.emory.edu:S-INBOX:CreateNewLineFromSocket: for <km(a)mathcs.emory.edu>;

[Dovecot] Dovecot2 Antispam plugin questions
by Steve Fatula 22 Jul '11

22 Jul '11

Tried to find some doc on this (other than the c code), couldn't, so, asking. I do almost every programming language, except C! When using DSPAM backend with this tool, will the plugin send ONLY the signature and not the entire message to dspam for retraining? Concerned about very large emails. If this is the case, I'd rather do this than use say the mailtrain backend which I presume would send the entire message. Having some permission problems though with the dspam binary since regular users can't execute dspam the way it is currently set up. Any security reason to not allow regular users to run the binary?

[Dovecot] Shared folders and home directories
by Christian Lerrahn 21 Jul '11

21 Jul '11

Hi, I've recently migrated a server from a Qmail/VPOPMail setup to a Postfix/system accounts setup. Everything worked pretty much out of the box after just changing the passdb and userdb to pam and passwd. However, I cannot get my shared folders to work. In the logs I will always see something like Jul 21 07:24:10 mybox dovecot: IMAP(foobar): Namespace 'shared/': Could not lookup home for user bla Jul 21 07:24:11 mybox dovecot: IMAP(foobar): userdb lookup: connect(/var/run/dovecot/auth-master) failed: No such file or directory Now, I don't understand why I need auth-master to find the home directory of user "bla" (who owns the shared folder). However, even if I configure auth-master, only the error messages will go away but I still can't see the shared folders. The configuration (as shown below) worked fine with vpopmail and is just taken from http://wiki.dovecot.org/SharedMailboxes/Shared . What do I have to change to make this work with passwd instead? Do I really need auth-master? If yes, how do I need to set it up to do the job properly?

[Dovecot] %w variable is missing
by Tom Sommer 21 Jul '11

21 Jul '11

Hi, I just noticed that the %w variable is now empty, after upgrading to version 2.0.11? I can still find references to it in the documentation, and in doc/wiki/Variables.txt - but the variable is empty and I can't find any references to it in the sourcecode. Was it overlooked or has it been removed? I'm in need of it :) Thanks. // Tom

[Dovecot] POP3 vs. IMAP Load/Memory usage in Dovecot 1.0.15
by lists＠truthisfreedom.org.uk 21 Jul '11

21 Jul '11

Hi all, We've just provisioned a new cluster of dovecot nodes running Centos and Dovecot 1.0.15 (we needed to match the original configuration, we're upgrading to 1.2 next week!). The nodes are currently equally allocated (50/50 split) to IMAP and POP3, with the intention to move them into a single cluster hosting both services in the next month. All the servers are of identical spec (24 cores, 24G RAM) and are configured to load the indices, control files and maildirs via NFS. We have noticed that the IMAP servers appear to be under much less load and utilising drastically less RAM than the POP3 servers and I'm wondering if there is a reason for this as we have seen some swapping onto disk yet we are only handling 500 concurrent POP3 connections to each server at any given time compared with over 600 IMAP connections. I'm wondering if we've missed a config flag somewhere or (better still!) this issue will go away when we upgrade to 1.2. If anyone can shed any light on this, that would be much appreciated. Thanks in advance, Matt
