[Dovecot] dbox vs. mdbox
by Douglas Mortensen 20 Apr '12

20 Apr '12

What are the pros and cons of both? Especially in regards to performance, stability, management & maintenance? I really appreciate feedback. We're on a time-crunch to migrate from a debian 5 box w/ dovecot 1.1 to a debian 6 box w/ dovecot 2.0.9 (built from source).

[Dovecot] Custom LDAP filter for doveadm-mailbox?
by Zhang Huangbin 19 Apr '12

19 Apr '12

Dear Timo, With Dovecot-2.0.16, 'doveadm mailbox list -A' will perform LDAP search with filter "(objectClass=posixAccount)", and get value of attribute 'uid' as mail user. Is it possible to custom the ldap filter and returned attribute name? For example: - LDAP filter: (&(objectClass=mailUser)(accountStatus=active)) - Returned attribute name: mail Did i miss something? Thanks. ---- Zhang Huangbin iRedMail: Open Source Mail Server Solution for Red Hat Enterprise Linux, CentOS, Scientific Linux, Debian, Ubuntu, Mint, Gentoo, openSUSE, FreeBSD: http://www.iredmail.org/

by Joseph Tam 19 Apr '12

19 Apr '12

I noticed the addition of a new namespace configuration "alias_for". What pracical difference is adding this over and above making namespace aliases hidden and disabling list, as in older versions of dovecot configurations? Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] old messages being delivered to blackberry
by Luc Belliveau 19 Apr '12

19 Apr '12

Several users are reporting old messages (sometime years old) are being delivered as new on their blackberry devices... I've confirmed that this happens to all blackberry users... I believe the problem is related to this error: Maildir: Expunged message reappeared, giving a new UID In fact, this is the only mail related error message on the server... the mail is stored on a glusterfs share, and I'm using director to prevent simultaneous access... although I wasn't able to get LMTP to work with Director... to simplify things, I've temporarily only enabled 1 dovecot server anyway, to get everything else working first... I'll fiddle with lmtp later... so right now only 1 server is accessing the mailboxes. Delivery is also done from that one server, from postfix. Possibly caused by GlusterFS, the indexes were still getting corrupted, even with only 1 server... so I've moved the indexes to a local directory on each server. I'm no longer getting index related errors... but the expunged error is still occuring... and the error seems to happen a few moments before the BB gets a bunch of messages... so it's very likely related. I would like to continue using GlusterFS if possible; I haven't found any indication that it is outright unsupported, as long as I'm using Director... I am using dovecot 2.0.16. Any help would be appreciated!

[Dovecot] Re-indexing of fts-solr not working
by Joe Beaubien 18 Apr '12

18 Apr '12

Hi, I am currently testing a 2.1 dovecot setup with fts-solr. Search speed is simply amazing. I decided to try to delete and rebuild the solr indexes, but i can't seem to rebuild them thru dovecot. At first, when telnetting to the imap server, the search initially built the index, and then subsequent searches are blazingly fast. 1- I deleted all the solr indexes with the following query: <delete><query>*:*</query></delete> 2- Flag the mailbox to be re-indexed: doveadm force-resync INBOX At this point, it doesn't work. When I telnet into the imap server, the searches always come back empty 3- I also tried a few other commands: doveadm fts rescan, doveadm index INBOX. Still no search results. Nothing seems to be appearing in the logs when I issue all the doveadm commands. What did I miss? Thanks, Joe
