[Dovecot] Suggested location for single-dbox
by William Blunn 03 Sep '10

03 Sep '10

I've updated http://wiki2.dovecot.org/MailLocation regarding a typical mail_location entry for dbox. Previously it said: mail_location = dbox:~/dbox but of course "dbox" is now the old name for "sdbox", so the example should be updated to say "sdbox" and there might/ought also to be an example for "mdbox". In http://wiki2.dovecot.org/MailboxFormat/dbox the example mail_location for mdbox is given as "mdbox:~/mdbox", so I have followed that for "MailLocation". So I have changed it to say # single-dbox mail_location = sdbox:~/dbox or: # multi-dbox mail_location = mdbox:~/mdbox I didn't know whether to change the directory for sdbox to "~/sdbox" or to leave it as it is. For the time being I have left it at "~/dbox" --- following the example given should allow new installations of Dovecot 2 to be able to read any existing single-dbox data which used the historically-suggested "~/dbox" location, whilst at the same time avoiding using the old mailbox format name of "dbox".

Hi to all, we are using quota to collect statistics about usage of mailboxes (thanks to the one who implemented :noenforcing) and we are using “maildir” backend, but we are thinking to migrate to *dbox (as soon as “per-user \Seen flag” would be implemented) and we should need a faster way to collect statistics, so I’ve tried to use Postgresql as a backend.

[Dovecot] bogus fts percentage

Sometimes dovecot-2.0 sends this untagged response to clients: * OK Indexed -2147483648% of the mailbox, ETA 0:00 I imagine there's a bug in there somewhere.

[Dovecot] LMTP plugin with MySQL query
by Charly 03 Sep '10

03 Sep '10

Hello, I want to create a plugin to dovecot 2.0.1, to call a on the deliver action. My plugin work even if I include other libs like mysql or wathever I tried to use the "sql-api.h" (lib-sql), but at runtime, I have : "undefined symbol: sql_init", "Fatal: Couldn't load required plugins" Is it possible to use lib-sql api or mysql libs in a plugin ? I've tried with lda or lmtp plugin with the same result... Any idea ? Charly.

[Dovecot] My "%%" variables in the namespace settings do not appear to be expanding.
by Kenneth Cope 02 Sep '10

02 Sep '10

Hello, I've been using the dovecot 1.2.x branch server software for a while now. With the advent of the 2.0.x branch going 'stable' I decided to attempt a migration and make use of some of the features that I've not needed before. One of these is the shared folder/namespace feature. No luck. I've hit a wall and can not determine the problem. At the moment it looks like a bug to me, but it may well be that I'm missing some related configuration, or file permission. I can not get the %% variable expansion in a namespace to work. What I end up with, on an IMAP connection is a directory named, for instance, '%h'. The same goes for any of the %% variables used at this point. My current set-up is 'not' the same as the current setup and I'm using virtual users that are not 'live' on the current system. I would really appreciate it if someone could cast an eye over my config and let me know if I've missed something obvious. Thanks.

[Dovecot] Dovecot - some more optimisations
by Len7hir 02 Sep '10

02 Sep '10

I did some more optimisation. Most performance hit in Dovecot do "for loop" in string operations. In one case (in message-parser.c) "for loop" has another "for" inside with the same variable used as iterator. This case is very hard to optimise by compiler. I do changes only in top functions listed in oprofile. Maybe I do more in future. Code was analysed and tested but it's hard to generate all cases. It's working well in production server (I'm monitoring). In istream-crlf.c I've changed one thing. When destination buffer is full after '\r' addition (to dest), It didn't skip '\n' in source buffer. I think this was buggy in earlier code, and '\n' was skipped (this piece of code is used very rare). Please check this out. This can help in huge e-mail systems :P And another problem. Why You use safe_memset instead of memset? Now this function have the largest impact in Dovecot performance. Another on list is t_push. Regards, Len7hir
