doveadm dump ignores .pvt
by Thomas Herrmann 14 Jul '14

14 Jul '14

While debugging a different problem, I used "doveadm dump" to show information about a maildir folder; it happily reported values from dovecot.index and dovecot.index.log (confirmed by strace): [...] messages count ........... = 978 seen messages count ...... = 967 [...] However, mail clients reported different values, I guess because the Seen flags were actually stored in the dovecot.index.pvt.log files. Is this a known problem or a result of my (maybe unsupported?) setup? My public maildir folder contains only links to mailboxes of the private maildir of the mail admin, i.e.: /home/vmail/public/.Info -> ../adwin.de/mail-admin/Maildir/.Info namespace { list = children location = maildir:/home/vmail/public:INDEXPVT=/home/vmail/adwin.de/%n/public prefix = ADwin/ separator = / subscriptions = no type = public } My setups leads to .pvt-files in the public namespace, could this be a problem? http://wiki2.dovecot.org/SharedMailboxes/Symlinks explicitly states that symlinking _should_ work. Using version 2.2.13 (debian packages). Regards, Thomas

Flags in public folders disappear when more than 25 flags are used
by Thomas Herrmann 14 Jul '14

14 Jul '14

Hello, I have been using flags in public folders for quite a while with no problems. Once the flags were added to all clients (Thunderbird), they were visible and synchronized properly. Now I have added some new flags, and in the dovecot-keywords files I see that I am now using more than 25 flags (in which case they are not stored using an additional letter in the filename). Now I see that newly added flags are only visible in the client for a short time and then suddenly disappear. How can I debug this, or what may be a reason for this?

High user number tune
by Edwardo Garcia 13 Jul '14

13 Jul '14

Halo, This might seem like another indirect thread. I Monday started new job, first task must replace courier. The job use POP3. and IMAP only for webmail, but must server support 4K POP3 at one times. I see from similar thread current settings not adequate , we will use TLS and if wiki read right Iprotocol So am close in think that need ? service pop3-login { process_limit = 4096 } service pop3 { process_limit = 4096 } service imap-login { process_limit = 2048 } service imap { process_limit = 2048 } then we have service managesieve { process_limit = 1024 } is that all we need change? I see in other thread someone says service anvil but I can not find out about it, does need change as well ? Why is it so complicated to change to let more user on, most other change one setting, dovecot want dozen :(

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

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.
