[Dovecot] Problem with configuring dovecot to take namespaces from database
by Marcin Mirosław 13 Sep '11

13 Sep '11

Hello! I'd like to set up dovecot to keep namespaces in database, keep more than one namespace per user. I try to create the simplest rule (even without tuple in db table) to get new namespace, unfortunately it doesn't work. My user_query is: SELECT '/dane/domeny/%d/mail/%n/' as home, dovecot_typ_skrzynki ||':'|| '/dane/domeny/%d/mail/%n/' ||'.'|| dovecot_typ_skrzynki as mail_location, '*:bytes='||quota_mb||'M' as quota_rule , 'test33/location=mdbox:~/.mdbox/test33/' as "namespace/test3/prefix" In debug log i'm getting: Debug: master out: USER#0111#011user@examle.com#011home=/dane/domeny/mejor.pl/mail/marcin/#011mail_location=maildir:/dane/domeny/mejor.pl/mail/marcin/.maildir#011quota_rule=*:bytes=0M#011namespace/test3/prefix=test33/location=mdbox:~/.mdbox/test33/ If i knew how it should look like the line in auth debug log for working configuration it could be easier for me to write correct sql query. May i please for advice?

[Dovecot] MySQL, map files
by Steve Fatula 13 Sep '11

13 Sep '11

I'll try and break up my questions the other day about extdata that went unanswered into pieces in the hopes it will be more specific and clear. In general, I am trying to figure out the syntax of the map statement and what is allowed in that statement. So, by map statement, I mean for example perhaps the dovecot-dict-expire.conf.ext file as shown in the doc. Is the syntax the same for the various types of files (quota vs expire)? Is there syntax to allow the specification of a different key? If so, where is this documented. I have an existing table I want to use, not the table shown in the doc. The reason I am asking is I have seen web pages that reference all sorts of statements within the map statement, and I have no idea where they are documented. Specifically, I see an example here (which is LDAP), look in section 3: http://dovecot.org/patches/1.2/ldap/HOWTO_dictldap+extdata.txt You will see lots of statements, not sure which ones can be used for MySQL (instead of LDAP). So, would like to find a list of ALL valid syntax within the map.

[Dovecot] director ignoring director_mail_servers for lmtp connections

Hello, Following Jan-Frode's advise I am trying this configuration: {postfix} ---lmtp---> {director} ---lmtp---> {dovecot} so I have two dovecot instances for director/proxy and lmtp delivery on ports 1024 and 24 respectively. whilst for imap connections I can specify a pool of imap backend servers via 'director_mail_servers' it seems is not possible with lmtp.

[Dovecot] signal 11 crash, sometimes, during mbox bz2 decompression
by Mike Brown 13 Sep '11

13 Sep '11

Hello again, I'm running dovecot 1.2.16 from the ports collection on FreeBSD 8.1-STABLE, amd64. To enable IMAP read-only access to gzip or bzip2 compressed mbox files, I added the following to my dovecot.conf, in the protocol imap { ... } section: mail_plugins = zlib My compressed mbox files are all .bz2 files in an 'old' subdirectory of my main mail directory. I am trying to access them with Thunderbird. I 'subscribed' to them just fine, and at first I thought it was working, but I just got lucky on the first couple I accessed. Dovecot actually fails to decompress them about 90% of the time, seemingly at random; the same box will not work a bunch of times, then work once, then not work again and again. When it works, sometimes only some of the messages get transmitted. Most of the failures are accompanied by this pair of messages in my log: Aug 16 00:25:33 myhost dovecot: dovecot: child 943 (imap) killed with signal 11 (core not dumped - set mail_drop_priv_before_exec=yes) Aug 16 00:25:33 myhost kernel: pid 943 (imap), uid 1001: exited on signal 11 Some of the failures have only the "exited on signal 11" message. The very first failure had this: Aug 16 00:22:47 myhost dovecot: IMAP(mike): Next message unexpectedly lost from mbox file (read-only mbox stream) at 2761 (cached) Aug 16 00:22:47 myhost dovecot: IMAP(mike): read(mail, uid=2) failed: Invalid argument Is this a problem with dovecot? Let me know if/how I can help, or what other info you need. Thanks, Mike

[Dovecot] Custom error messages.
by Lauro C. 12 Sep '11

12 Sep '11

I am using Dovecot 1.2.9. Is it possible to have custom error messages? I want to translate some of the messages (for instance mailbox full), so it can be more user friendly. I already use the quota warning feature. But I need to translate the messages anyways, is it possible? Lauro
