Hi, @all! Is it possible, with Dovecot, to do something (eg: an SQL-Query) when the User logs out (POP3) or do some action (IMAP)? My problem is to notify a DB when the user logs out or delete E-Mail (in this case, just for IMAP). Thanks for your answer! P.S.: if it is NOT possible, it is my Hit for the next version! :) -- _______________________________ Luca Bertoncello -Programmierung / Mailserver- IMS Internet-Media-Service GmbH Bayrische Str. 18 01069 Dresden Geschäftsführer: Axel C.E.

[Dovecot] fs quota - what I am doing wrong?

Hi everyone, on my server, i have quota set on /home partition (ext3). mount says: root@zen:/var/log# mount |grep quo /dev/sda8 on /home type ext3 (rw,noatime,usrquota) /dev/sda7 on /tmp type ext3 (rw,noatime,usrquota,data=writeback) System is debian/stable (distribution 2.6.8-3-686-smp kernel), quotas are working: root@zen:/var/log# quota ax Disk quotas for user ax (uid 506): Filesystem blocks quota limit grace files quota limit grace /dev/sda8 148064 250000 300000 7066 0 0 /dev/sda7 16 10000 300000 5 0 0 but dovecot has trouble with them: root@zen:/var/log# grep ax mail.err |tail -n 4 Feb 26 15:02:27 zen dovecot: IMAP(ax): quotactl(Q_GETQUOTA, /dev/sda8) failed: Invalid argument Feb 26 15:02:27 zen dovecot: IMAP(ax): Dovecot was compiled with Linux quota v2 support, try changing it (--with-linux-quota configure option) Feb 26 15:03:28 zen dovecot: IMAP(ax): quotactl(Q_GETQUOTA, /dev/sda8) failed: Invalid argument Feb 26 15:03:28 zen dovecot: IMAP(ax): Dovecot was compiled with Linux quota v2 support, try changing it (--with-linux-quota configure option) In sheer desperation I compiled dovecot with v1 quotas, but that fails too. Can anyone point me into right direction? Ax -- Václav Hůla, správce unixových serverů Přírodovědecká fakulta Univerzita Karlova v Praze

[Dovecot] How to Prevent IMAP Folders being moved, deleted or renamed
by FreeStyle 01 Mar '07

01 Mar '07

Hello I use exim/dovecot combination for mail delivery and pickup and I'm wondering how I can prevent users from moving, deleting or renaming particular IMAP folders. I use the MailDir mailbox format. The reason for doing this is that I have some special exim filters which deliver mail to specified directories. I don't want users to be able to change these folders because it will mess up the filtering. Also my mail client (Thunderbird) doesn't check the filter folders automatically is there an option in dovecot that lets you send notification to clients when new messages arrive in certain folders. more info: http://kb.mozillazine.org/How_do_I_check_for_new_messages_in_other_folders

[Dovecot] segv when Mailbox is in inconsistent state, please relogin.
by Steffen Kaiser 01 Mar '07

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, for testing I have different filesystems on various block devices, which I mount on /mnt/mailcache as needed; however, the indexes and caches are located on /var/cache, hence, they get out of sync easily. No offense. Hoever, the web page (http://dovecot.org/bugreport.html) states that every signal 11 is a bug and will be fixed, so here it goes: running Linux x32, Debian Etch, Dovecot rc23, MUA: Thunderbird. It occurs to me that the data on /var/cache must be younger than the one on /mnt/mailcache; e.g. when you re-login after the segv, it works fine. There seems to be one segv per folder with messages.
