[Dovecot] Sieve and LDA
by Vincent Bernat 31 Jan '07

31 Jan '07

Hello ! I have started to use Sieve support in LDA. From the RFC a same message should not be delivered twice in the same folder : ,---- | 2.10.3. Message Uniqueness in a Mailbox | | | Implementations SHOULD NOT deliver a message to the same folder more | than once, even if a script explicitly asks for a message to be | written to a mailbox twice. | | The test for equality of two messages is implementation-defined. | | If a script asks for a message to be written to a mailbox twice, it | MUST NOT be treated as an error. `---- Dovecot seems to ignore this "SHOULD NOT" or am I missing something ? At first, I thought they were speaking of case where there is two idententic "fileinto" directive in the ruleset. Something like : fileinto "box"; fileinto "box"; But, I don't think that they would they "the test for equality of two messages" with such a trivial case. Maybe dovecot should maintain a list of recent message-id seen for each user (with the associated mailbox). -- I WILL ONLY DO THIS ONCE A YEAR I WILL ONLY DO THIS ONCE A YEAR I WILL ONLY DO THIS ONCE A YEAR -+- Bart Simpson on chalkboard in episode 3F31

[Dovecot] Need help with "mbox sync" problem
by Jim Garrison 31 Jan '07

31 Jan '07

The following is occurring consistently on users in only one vhost domain. Other vhost domains are not having the problem. The email client in use is the same (in both the working and non-working domains). dovecot: Jan 29 21:19:18 Error: POP3(user1(a)mydomain.tld): mbox sync: UID inserted in the middle of mailbox /var/mail/vhosts/mydomain.tld/user1 (5629 > 5423, seq=2, idx_msgs=5) dovecot: Jan 29 21:19:18 Info: POP3(user1(a)mydomain.tld): Disconnected: Logged out top=0/0, retr=95/508506, del=95/95, size=506866 dovecot: Jan 29 21:19:52 Error: POP3(user2(a)mydomain.tld): mbox sync: UID inserted in the middle of mailbox /var/mail /vhosts/mydomain.tld/user2 (5634 > 5629, seq=2, idx_msgs=95) dovecot: Jan 29 21:19:52 Info: POP3(user2(a)mydomain.tld): Disconnected: Logged out top=0/0, retr=5/69654, del=5/5, si ze=69562 Once this message starts occurring, dovecot stops deleting retrieved messages when the user retrieves mail (with 'delete from server' set). The result is that the entire mailbox contents are fetched each time, resulting in copious amounts of duplicate messages. I'm on the rc8 RPM that comes with FC5, but am willing to remove it and install a later Dovecot built from source. 1) Is this a known problem that can be fixed by upgrading? 2) If not, can someone tell me what this message means exactly, and how to gather more information for debugging? The MTA is Postfix. Thanks

Make sure your acl file ends with LF (there is an empty line at the end) otherwise dovecot doesn't read the last line.

[Dovecot] How to prevent SQL injection
by Jochen Schulz 31 Jan '07

31 Jan '07

Hi, on my way home today I thought a little bit about my setup which involves user and password lookups in an SQL database (Postgres). I asked myself whether I need to do anything to prevent SQL injection via forged user or domainnames. In the wiki I didn't find anything specific, only http://wiki.dovecot.org/Variables which mentions that there is the %E modifier which escapes single quites and backslashes. This appears to be a good idea but I am asking myself whether I need to do this since it is not mentioned anywhere. Is anybody able to comment on this? And BTW, it appears that one can use several modifiers at once. This is only implicitly mentioned in the wiki (You can apply modifier*s*), but it appears to work.

Perhaps what you might be seeing is file system caching. I notice this when performing NFS I/O tests: the first re-read is fast but decays over time as data is rolled out of the cache.

[Dovecot] Looking for IMAP maintenance tools
by Jens Knoell 31 Jan '07

31 Jan '07

Hi I'm currently prowling for some IMAP tools to help me maintain our mailboxes. I'd prefer "pure" IMAP, i.e. no messing with file system directly, but would settle for more crude ways if need be. Specifically I am looking for: - Expunge tool: Outlook does not seem to auto-expunge messages in any way shape or form. So I'd like to run a daily cron to expunge all mailboxes. - Quota helper: Some way to send a warning email once a day or so, saying "you're close to your quota limit, please delete some mail" or somesuch Granted, I could write these two from scratch - but why reinvent the wheel? Thanks Jen
