Pigeonhole sieve misfile
by Patrick Domack 13 Jul '14

13 Jul '14

I'm having an issue with sieve putting some emails into the spam folder, that should not be matching the spam rule. I tried looking but can't seem to find a debug option. Is there any way I can get a log of what the sieve rule path that matches so I can locate the misfiring rule? or maybe something else that is going on. I already checked the dovecot sieve log file, and there is nothing in there.

macros
by Arkadiusz Miśkiewicz 13 Jul '14

13 Jul '14

Does dovecot support any form of macros? I would like to share configuration file between several servers. Configs are different only in tiny aspects. Somethine like: dovecot-server.conf (different on each server): %define ID 55 %define SOMETHING SELECT FROM * WHERE something %define MECHANISMS digest-md5 dovecot-main.conf (common, shared config) !include dovecot-server.conf user_query = ${SOMETHING} AND id=${ID} auth_mechanisms = plain login ${MECHANISMS} etc -- Arkadiusz Miśkiewicz, arekm / maven.pl

Replication on dovecot 2.0
by Tom Barber(Alabs) 11 Jul '14

11 Jul '14

Hi Guys I'm running an Ubuntu 12.04 LTS server and not being particually inclined to upgrade I'm wondering what options I have for replication as it appears to be running dovecot 2.0.19. I saw the wiki page about replication and whilst it says you should use 2.2+ it doesn't say what the minimum requirements are, so I tried doing what it says but I get: Fatal: Plugin 'replication' not found from directory /usr/lib/dovecot/modules Any ideas or tips. Thanks Tom

1.2.4 disk full errors
by Iain Hallam 11 Jul '14

11 Jul '14

Hi. A user on a rather old mail system we have filled their disk space, and Dovecot has started to give lots of errors in the logs about "Expunged message reappeared" and "Duplicate file entry". The user can only see a few new messages, not the 33,551 in their inbox. In the TODO file in the current source code[1], Timo notes that (line 147): maildir: out-of-disk-space failures apparently cause all kinds of problems, e.g. "Expunged message reappeared", "Duplicate file entry"? [1] http://hg.dovecot.org/dovecot-2.2/file/c55c660d6e9d/TODO Does anyone know what's happening with Dovecot here and how to recover so that this user can see mail again? Unforuntately we're on a very old version, 1.2.4. Though there is a plan for migrating to a newer platform, I need to get this user accessing email again rather more urgently. Thanks, Iain Hallam.

dovecot lda invalid user settings
by CJ Keist 10 Jul '14

10 Jul '14

I'm now dealing with issue with some users on mbox getting invalid user settings in /var/adm/messages. /var/log/syslog has: Jul 10 11:21:42 mail2 dovecot: [ID 583609 mail.error] lda(ejames): Error: user ejames: Initialization failed: Namespace '': Mail storage autodetection failed with home=/top/academic/Atmos/people/ejames/home Jul 10 11:21:42 mail2 dovecot: [ID 583609 mail.crit] lda(ejames): Fatal: Invalid user settings. Refer to server log for more information. I checked this users home directory and the mail folder is there and permissions are all correct. I'm running in a mixed mbox and Maildir environment. I read to support this environment you simply comment out the mail_location lines in 10-mail.conf file which will force dovecot to auto detect what format a user is using.

Hi All, I have the Dovecot quota value coming from LDAP using the line below but my values are stored in MB, not bytes. What can I put in the line to set quotas in MB? user_attrs = homeDirectory=home,mailUID=uid,mailGID=gid,mailQuota=quota_rule=*:bytes=%$ Thanks Murray

Trigger for using an sqlite dictionary for quota
by David Anderson 10 Jul '14

10 Jul '14

Hi, I'm using Dovecot 2.0.9, and was trying to set up a dictionary process to use an sqlite database for quota management. The wiki page has examples for MySQL and PostgreSQL: http://wiki2.dovecot.org/Quota/Dict For sqlite, a trigger needs to be created to get it to work. But I was not sufficiently skilled in sqlite to adapt the PostgreSQL trigger (given on the above URL) for use. Nor did Googling find any example of anyone else who had done it. Does anyone here have an example, or the ability? (Through Googling I found an example trigger for using sqlite with expiries - but I was looking at quotas).

HIGHESTMODSEQ tracking
by Kostya Vasilyev 10 Jul '14

10 Jul '14

Hello, I'd like to follow up on someone else's old thread: http://dovecot.org/list/dovecot/2012-April/082624.html I understand that Dovecot (that 2012 discussion was about version 2.0.18) can return "HIGHESTMODSEQ 1" upon SELECT if persistent modseq tracking was never enabled for a mailbox. I'd like to get a clarification on how to enable proper persistent modseq tracking. Per RFC 4551, "A client supporting CONDSTORE.... indicates its willingness to receive mod-sequence updates... by issuing:" SELECT mailbox (CONDSTORE) STATUS (... HIGHESTMODSEQ ...) ... others ... It seems that Dovecot 2.1.7 (Debian 7.5) enables persistent modseq tracking after one of the above two commands (and maybe others). So far so good. So my questions are: 1 - Is this (enabling persistent modseq) also the case for all Dovecot versions prior to 2.1.7 that advertise CONDSTORE? There must be people running older versions out there, older than 2.1.7. If not, how can I branch my logic to not use HIGHESTMODSEQ, given that Dovecot doesn't appear to return any version info via its greeting or via the ID command? 2 - Is persistent modseq tracking (assuming it's been enabled) available for all types of backend mailbox formats that Dovecot might be using? To be more specific, can it ever be the case that Dovecot appears to enable modseq tracking, returning nice looking HIGHESTMODSEQ values from SELECT / STATUS, but the actual values get reset or not get updated because they're not properly persistent? I'm excluding changes to UIDVALIDITY here, obviously when that changes, the entire mailbox state must be assumed to have changed completely. 3 - I guess the change to return NOMOSEQ instead of "1" for mailboxes with modseq tracking disabled, as mentioned in that discussion from 2012, never happened? At least on the 2.1 branch? Thanks, -- K
