[Dovecot] dsync-2.2.7 incorrectly synchronizes subscription status of renamed mailbox
by Karol Jurak 21 Nov '13

21 Nov '13

Hi, It seems that dsync-2.2.7 doesn't correctly synchronize subscription status of a renamed mailbox. The situation is as follows. There are two servers: A and B, and a test user test_mdbox. Mailboxes (mdbox) of this user on both servers are synchronized. Specifically on both of them there is a (subscribed) Test1 mailbox. Replication plugin is disabled. I rename Test1 to Test2 on A with Thunderbird. The output of 'doveadm mailbox list', contents of subscriptions file and the output of 'doveadm dump -t mailboxlog dovecot.mailbox.log' (below) confirm that the rename succeeded on A. #2976: rename 2b84f621c0fd4ba8bd514c5c43ab9a89 (2013-11-19 14:30:35) #3000: subscribe 2b84f621c0fd4ba8bd514c5c43ab9a89 (2013-11-19 14:30:35) #3024: unsubscribe 99ea7bf70f6e69ad71659995677b43f8 (2013-11-19 14:30:35) Subsequently I run 'doveadm sync -u test_mdbox remote:B'. Nothing changes on A. On B 'doveadm mailbox list' shows that Test1 was renamed to Test2, but subscriptions file still contains Test1 and not Test2. The output of 'doveadm dump -t mailboxlog dovecot.mailbox.log' confirms that only rename was performed: #2160: rename 2b84f621c0fd4ba8bd514c5c43ab9a89 (2013-11-19 14:57:22) Only another 'doveadm sync -u test_mdbox remote:B' fixes subscriptions on B. The following records are added to dovecot.mailbox.log: #2184: unsubscribe 99ea7bf70f6e69ad71659995677b43f8 (2013-11-19 15:00:32) #2208: subscribe 2b84f621c0fd4ba8bd514c5c43ab9a89 (2013-11-19 15:00:32) -- Karol Jurak

[Dovecot] Enable Rawlog from userdb in Dovecot v2.2
by Steffen Kaiser 21 Nov '13

21 Nov '13

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, how do I enable Rawlog for one person only? http://wiki2.dovecot.org/Debugging/Rawlog describes how to enable the postlogin script for all users. Rawlog gets active only, if the dovecot.rawlog directory exists. So far, it's working. However. I suspect that there is some notable overhead in this chain, so I tried to enable rawlog via userdb extra fields. So setup the config as: service imap { executable = imap } service postlogin { executable = script-login -d rawlog unix_listener postlogin { } } In the userdb extra fields I tried: service/imap/executable=imap postlogin Log entry: imap: Debug: Unknown userdb setting: plugin/service/imap/executable=imap postlogin and: service imap/executable=imap postlogin (note the space between service imap) Log entry: imap: Debug: Unknown userdb setting: plugin/service imap/executable=imap postlogin - -- Steffen Kaiser -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iQEVAwUBUoDzAV3r2wJMiz2NAQJxgwf+NCaABKspwVffTpQqVIAdlXGi2gUrRd29 1Ic82v5xqx8jMQ+UxnKNJBX2jgs87GITWpPtTXUVS8H6piNDJrcAxT0lIun0l4Ob 4riQh01HrMjwWORAAWvHHQWZbyiDu8i2h8PjQAG/8idpCt0lCmmr2DyRQwSx+7lf JgfxfccYMRhAHtethm82cjWs3Q/M9deO+ds+aLwxGhDaYxHcU8vD3ESuhqnsR4Bh VqemH3wBADpfKH3ThRKknsfGfEU5d8bcz1GzhOcjfwC24kPsei4k9wcDAy+moyk1 8vPYyvWnhhfb0/yiO3eLpX0mdlM9Iur1X3MFvA0tFwnB8RtuqZGw3g== =/TtK -----END PGP SIGNATURE-----

[Dovecot] Reset vacation lda-dupes database
by Mike Selner ＠ Yahoo 20 Nov '13

20 Nov '13

Hello, I have dovecot 2.2.6 and pignenhole 0.4.2 running on freebsd9.1. We have a mix of unix users (/home/user) and postfixadmin users (/home/vmail/domain/user). I am using dovecot managesive with afterlogic webmail which has a managesieve plugin to set the out of office message. All works fine. I have sieve_vacation_default_period set to 1d. The problem I'm trying to solve is that users set their vacation message and want to test it. So they have their colleagues send them multiple test messages and want to make sure it works. Of course only the first message gets an auto-reply. I tell them that the auto responder only sends one message per day per sender but they would like to test it with a new message etc. So I have to remove their .lda-dupes file manually so they can try again. My previous autoresponder setup (squirrelmail) used a .forward technique and removed the vacation database when they turned the responder from off to on, and this worked well for the above issue. Is there a solution for dovecot managesieve which will remove or reset the .lda-dupes file whenever a new sieve file is uploaded? Or another solution that will reset the "vacation timer" when the user turns vacation from off to on? Thank you Mike

[Dovecot] status=undeliverable (lost connection with mail.larptreff.de[private/dovecot-lmtp] while sending MAIL FROM)
by Jan Phillip Greimann 20 Nov '13

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Good morning dovecot-community, I noticed a strange log-entry since the last day: Nov 7 08:34:42 hetzner postfix/lmtp[3764]: 61CB01A3938: to=<jg+introversion(a)larptreff.de>, relay=mail.larptreff.de[private/dovecot-lmtp], delay=0.05, delays=0.01/0.01/0.02/0.01, dsn=4.4.2, status=undeliverable (lost connection with mail.larptreff.de[private/dovecot-lmtp] while sending MAIL FROM) Thankfully I've configured a cronjob for a daily pflogsumm-report, but I don't understand this. It worked for months like a charm. It seems this only happens on mails with "+"-Delimiter. In my opinion there is only one thing which could cause this problem: I updated my dovecot on 2013/11/04 from 2.2.6-1~auto+36 to 2.2.7-1~auto+2 maillog: http://pastebin.com/WDGfEjdp doveconf -n: http://pastebin.com/ay6dxiUf I will try to downgrade again, did someone have a clue? Changelog from 2.2.7 didn't show changes on lmtp.

[Dovecot] UID order vs date order
by Torbjorn Jansson 20 Nov '13

20 Nov '13

Hi i have recently moved a mailbox to dovecot and intend to use it via imap and i have run into a problem. when i imported the mails apparently the UID order got reversed compared to the date order, result is that some clients like on android devices download the oldest mails instead of newest. it is not so interesting to have several years old mail show up at the top of the mailbox. is there any way of convincing dovecot to renumber the mails by date order instead? i have tried to delete the dovecot-uidlist and dovecont.index* files in an unimportant folder and the only thing that happens was that all of the mails got renumbered in the wrong order again (lower numbers but still same problem) any advice? i cant be the only one that have run into this.
