[Dovecot] Sieve 1.1.2 -> special chars
by mikkel＠euro123.dk 04 May '08

04 May '08

I'm unable to use local chars in vacation/auto replies with sieve. .dovecot.sieve.err gives the same error as when there's a parse error. Example of error: line 25: string 'æ ø å ö ä ü é á. ': My dovecot is v. 1.1b5 and sieve is v. 1.1.2. This issue was also present with dovecot 1.0.x Is there a way around this? - Mikkel

[Dovecot] Quota not showing correctly after conversion (mb2md.pl)
by k bah 04 May '08

04 May '08

-- SCENARIO -- I'm using dovecot-1.0.5-6 on opensuse 10.3. I use the maildir quota plugin, and I'm converting mailboxes from UW IMAP (mbox) to Maildir format using that mb2md.pl script (3.10 I guess). My migration happens like this: - if a user receives mail (before ever using the new mail system), it goes to his/her inbox, dovecot proceeds normally, like when a user exists, but never received mails. Quota is shown ok. - if a user logs in before receiving any new mail, then, /var/spool/data/USER/new is created, and all converted messages are copied to that dir. If that user had deleted messages (some users mark messages as deleted, others delete for real), then a /var/spool/data/USER/.Trash/new dir is created, and messages are put there too. No other files/dirs (dovecot-uidlist maildirsize cur tmp), are created by "me" or the migration scripts. Index files (/var/spool/index/USER) are not created neither. They are created by dovecot itself. I have a problem, when a user has mails that exceed the limit in mb's (I set just size limit, no messages limit), neither "getquotaroot" (via telnet to port 143), neither webmail software (horde) show the quota usage correctly (I'm not talking about new mail, talking about those messages copied, when they exceed the size limit). Just after trying to delete messages it is shown (gives me an error message, quota exceeded, since Trash is not excluded from quota limits, for now, I'll exclude it later). This server has some issues: many old users have lots of mails, in thousands (1000-15000). Some have 50mb to 150mb of mails. The migration is part of the cleanup process. --- MY QUESTIONS --- Is it possible that the migration order (creating dirs in that way) is causing the quota usage to be shown wrong? Is it possible that the amount of messages and the size can be the cause? Misconfiguration? Other causes? How can I manually tell dovecot to recalculate the quota, after copying messages (when a user logs in, and didn't receive new mails on the new mail system, but had messages big enough to exceed the quota limit) from the old system? Should I run any commands to rebuild indexes or any operation to keep information integrity about the mails/mailboxes to dovecot, after copying the converted messages? many thanks = -- Powered by Outblaze

[Dovecot] Master user and missing folders
by Anders 04 May '08

04 May '08

Hello again. I am trying to use a master user. The login works. However, a LIST command gives me only the INBOX. Is this to be expected? When logging in normally, I do get the full list of folders. (using Dovecot 1.1 rc3.) Anders.

[Dovecot] Fatal: Running as root isn't permitted
by Juan Asensio Sánchez 04 May '08

Hi! It compiles perfect now and works fine without returning the uid in the ldap query. What about the inclusion of the antispam and autocreate plugins in the (source) debian package?

[Dovecot] The CONTROL problem with fs quotas.
by Jorgen Lundman 04 May '08

04 May '08

dovecot-1.0.10 on Solaris 10 x86, with NFS. We currently have the problem that when customers go over their disk quota, the dovecot-uidlist file stops them from logging in. In the interest of solving it, we considered moving the CONTROL file to a different file system. But: 1: Using CONTROL= with "%u" will quite quickly run into the problem that the directory will fill up, and hit the maximum (around 32k) or so. We have 170k users so far, and more are being imported. You could cull some from crontab or similar, but is generally a poor way to solve a problem. 2: We attempted to use CONTROL= with "%h", which would give us full directory hashing, however, we found that when it creates all the directories, it does so as the uid of the first user. So all following users (that hash in at least one part) will fail. Most likely because dovecot has already setuid()ed. Pre-creating the hashes is not feasible. 3: Using 2, we could change umask to "0000" and hence it does not matter than all directory hash node are owned by a user's id, but this unfortunately includes all other directories, and having all directories at 777 is not an option. Now, naturally, I can easily patch dovecot to call mkdir_parents with 0777 only for CONTROL. But I would rather not have local patches, meaning upgrades will be difficult. It would be preferable if: => Dovecot would call "mkdir_parents" on "%h" _before_ setuid, but create the final directory after. OR, Dovecot support (at least 2 level) directory hashing when specifying CONTROL=%1/%2/%u OR, The ability to disable dovecot-uidlist (in memory is fine). (Setting INDEX=memory does not work for CONTROL=). Are there other solutions out there? -- Jorgen Lundman | <lundman(a)lundman.net> Unix Administrator | +81 (0)3 -5456-2687 ext 1017 (work) Shibuya-ku, Tokyo | +81 (0)90-5578-8500 (cell) Japan | +81 (0)3 -3375-1767 (home)

[Dovecot] used_file_size too large
by Anders 04 May '08

04 May '08

Hi. Just got this error (1.1.rc4), is it something to worry about? Corrupted index cache file /.../Maildir/.Sent/dovecot.index.cache: used_file_size too large This is a shared mailbox with concurrent access. In general, can that usage pattern mess up the index? I am guessing "no", which is why I worry slightly about the warning. Cheers, Anders.

[Dovecot] Can't receive mail for virtual user
by Jeremy Gillick 04 May '08

04 May '08

I followed the dovecot instructions ( http://wiki.dovecot.org/HowTo/SimpleVirtualInstall) to create a simple virtual user installation with the /etc/dovecot/passwd file. However, whenever I try to send a message to the virtual user, Postfix has a problem delivering it. Postfix is delivering messages to ~/Maildir, but Dovecot is trying to use /home/vmail/.
