[Dovecot] New plugin for Pigeonhole Sieve: sieve_pipe
by Stephan Bosch 14 Sep '11

14 Sep '11

Hello, I've finished up work on a new plugin for Pigeonhole Sieve: sieve_pipe. It adds a new Sieve extension (vnd.dovecot.pipe) providing a new action command that provides the possibility to pipe messages to external programs (e.g. shell scripts). The programs available to this command are explicitly limited and subject to administrator configuration. The plugin can currently only be downloaded from the Mercurial repository: http://hg.rename-it.nl/pigeonhole-0.2-sieve-pipe Check the README/INSTALL files in the repository or the new wiki page for more information: http://hg.rename-it.nl/pigeonhole-0.2-sieve-pipe/raw-file/tip/README http://hg.rename-it.nl/pigeonhole-0.2-sieve-pipe/raw-file/tip/INSTALL http://master.wiki2.dovecot.org/Pigeonhole/Sieve/Plugins/Pipe The specification of the vnd.dovecot.pipe extension can be found here: http://hg.rename-it.nl/pigeonhole-0.2-sieve-pipe/raw-file/tip/doc/rfc/spec-… I'd still call this thing very much experimental, so be sure to test it extensively first. Don't hesitate to notify me when there are any problems. Regards, Stephan.

[Dovecot] quota percents
by Micah Anderson 13 Sep '11

13 Sep '11

I've noticed that http://wiki2.dovecot.org/Quota/Configuration is out of date, it says: plugin { quota = maildir:User quota quota_rule = *:storage=1GB # 10% of 1GB = 100MB quota_rule2 = Trash:storage=10%% # 20% of 1GB = 200MB quota_rule3 = Spam:storage=20%% } but if you use the '10%%' notation, dovecot complains, and *also* incorrectly: dovecot: imap(test(a)example.net): Warning: quota root mail quota rule Trash:bytes=10%: obsolete configuration for rule 'bytes=10%' should be changed to 'bytes=+10%' its incorrect because if you change it to what it suggests ('+10%') it wont work because that wont be 10% more, rather, it is set to bytes=+10: dovecot: imap(test(a)example.net): Debug: Quota rule: root=mail quota mailbox=Trash bytes=+10 messages=0 clearly, that isn't right... so I guess it needs to be changed to '+10%%', setting that provides: dovecot: imap(test(a)example.net): Debug: Quota rule: root=mail quota mailbox=* bytes=2211724 messages=0 dovecot: imap(test(a)example.net): Debug: Quota rule: root=mail quota mailbox=Trash bytes=+221172 (10%) messages=0 that seems ok, its saying the Trash mailbox is set to have 221172bytes (215 kilobytes) of quota. So, clearly http://wiki2.dovecot.org/Quota/Configuration needs to be updated. However, it doesn't seem to work in practice, because I have a user that is at 99% of quota, with nothing in the Trash who cannot move a 77KB message into the Trash without getting the quota_exceeded message and refusing to move it. so... how do I get this to work? thanks! micah --

[Dovecot] Migrating a dovecot setup from one server to another
by James Carr 13 Sep '11

13 Sep '11

Hi All, I have a server with a dovecot + postfix setup and unfortunately the server is EOL'd. I have built a new ubuntu server out and I'm in the process of migrating everything over. In migrating the dovecot setup over, this is the list of items I have done: install dovecot, postfix, etc on the new server copy configuration files over copy /var/spool and /var/mail over Is there anything else I need to consider before switching MX records to point to the new server? Thanks, James

[Dovecot] imapc and imap_acl
by Lutz Preßler 13 Sep '11

13 Sep '11

Hello (Timo), yes, I know... maybe it's a bit far fetched, but I do have a use case. Would it be (reasonably easily) possible to implement IMAP ACL support for "imported" imapc namespaces/mailboxes? There is no local directory (like with the virtual plugin) yet...

[Dovecot] Dovecot and Lustre FS
by Christian Gregoire 13 Sep '11

13 Sep '11

Hello, Right now, I'm using Exim and a customized version of an old (10 years old) Atmail POP3 server written in Perl, with ~10000 mailboxes located on a Lustre file system. So far so good. Though, I plan to migrate from Atmail to Dovecot, to provide our customers with IMAP support. Has anyone any experience with Dovecot on Lustre FS ? Thanks Christian

[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.
