[Dovecot] "%d" does not expand to domain on wildcard search
by Ramiro Blanco 24 Nov '11

24 Nov '11

Hi, I found that doing a wildcard search with doveadm doesn't expand the %d global variable when doing a wildcard search like: doveadm search *@domain ALL LARGER 10000k doveadm(root): Error: User listing returned failure doveadm: Error: Failed to iterate through some users In /var/log/dovecot.log: Nov 22 20:48:07 auth-worker: Debug: ldap: iterate: base=vd=%d,dc=domain scope=subtree filter=(&(objectClass=VirtualMailAccount)(accountActive=TRUE)) fields=mail Nov 22 20:48:07 auth-worker: Error: ldap(?): ldap_search((&(objectClass=VirtualMailAccount)(accountActive=TRUE))) failed: No such object Is this a bug?

[Dovecot] Random Loss of Connection with Thunderbird and Dovecot
by Jay Welch 24 Nov '11

24 Nov '11

Hi, Dovecot Version: 1.2.16 OS: CENTOS 5.5 I am having issues with Thunderbird connecting to Dovecot at random times. Usually an error comes up and states that Thunderbird cannot connect to the server. The only way I have been able to fix this is reset/repair the network connection or reboot the computer. Is there any parameters I can change in Dovecot to fix this issue? Does anyone know what is likely going on? I have been reading forums and I cannot find anything. Thanks

[Dovecot] Excluding some system users after configuration
by Nanitous 24 Nov '11

24 Nov '11

Dear readers, Consider an installed Postfix configuration (2.3.3) on CentOS. Now I want to install Dovecot (alas only version 1.0.7.7 is available) to provide IMAP services for a few system users, but not all. Most importantly the mail delivery by postfix for some of these system user /must/ not change after the installation of Dovecot. How can I prevent the installation of Dovecot to touch some specific system user accounts? Thanks in advance, /Twan

[Dovecot] How to disable pop3 in version 2?
by Knute Johnson 24 Nov '11

24 Nov '11

I'm about to bring up a new mail server running Ubuntu 11.10 with Dovecot 2. I've been using 1.2 all along and there are a bunch more config files in 2. In 1.2 I just edited the protocols statement but I can't find one in version 2. Is there a way to disable pop3 or do I just firewall the ports? And a related question, I've been using imaps on port 993 but I hear that's not the best solution anymore, I should be using imap with STARTTLS? How do I disable imaps? Thanks, -- Knute Johnson

Sorry about the HTML. I removed the string "-O2" from the /auth Makefile and, for good measure, did make clean, make and make install for all of Dovecot. Still, it crashed when trying to log in via IMAP (webmail). Core dumped, here's the backtrace. [snip] Core was generated by `dovecot/auth -w'.

[Dovecot] 1.2.15 can't get zlib working
by Stan Hoeppner 24 Nov '11

24 Nov '11

Following these instructions: http://wiki.dovecot.org/Plugins/Zlib I enabled zlib and restarted Dovecot. I made a backup copy of a 68MB mbox file and moved it to a non mail directory. The mbox file is an existing TBird IMAP folder in my UNIX user mail directory. It is an archive of a defunct mailing list. It was a regular IMAP folder prior to attempting this. I was able to access all emails in the folder. It worked fine. I gzipped the original mbox file down to 14MB and removed the write flag with chmod. I launched TBird and received the following error in Activity Manager when accessing this IMAP folder: The current operation on '1-Spam-l' did not succeed. The mail server for account stan(a)hardwarefreak.com responded: Mailbox doesn't exist: 1-Spam-l I deleted the Dovecot index files and the TBird 1-Spam-l.msf file which didn't help. Curiously, there are no entries in either dovecot.err or dovecot.log, giving not even the slightest hint as to where I should troubleshoot. Kinda sucks when one follows instructions exactly, simple instructions at that, and it doesn't work, and generates zero log errors. A bit frustrating...

[Dovecot] v2.1.beta1 released
by Timo Sirainen 23 Nov '11

23 Nov '11

http://dovecot.org/releases/2.1/beta/dovecot-2.1.beta1.tar.gz http://dovecot.org/releases/2.1/beta/dovecot-2.1.beta1.tar.gz.sig Here's the first beta release of Dovecot v2.1. This version has already been tested quite a lot, so I'm not expecting any major bugs. So please upgrade and see if you can find any problems. I'm optimistic about getting rc1 released this year and perhaps even v2.1.0. Since alpha2 there have been a lot of fixes, especially to imapc backend. There are probably also some small new features, but nothing huge. As a reminder, here's the largest changes since v2.0: * Plugins now use UTF-8 mailbox names rather than mUTF-7: acl, autocreate, expire, trash, virtual * auth_username_format default changed to %Lu. If you really want case sensitive usernames, set it back to empty. * Solr full text search backend changed to use mailbox GUIDs instead of mailbox names, requiring reindexing everything. solr_old backend can be used with old indexes to avoid reindexing, but it doesn't support some newer features. + imapc (= IMAP client) storage allows using a remote IMAP server to be used as storage. This allows using Dovecot as a smart (caching) proxy or using dsync to do migration from remote IMAP server. + Mailbox indexing via queuing indexer service (required for Lucene) + Lucene full text search (FTS) backend rewritten with support for different languages + FTS finally supports "OR" search operation + FTS supports indexing attachments via external programs + IMAP FUZZY extension, supported by Lucene and Solr FTS backends + Mailbox list indexes + Statistics tracking via stats service. Exported via doveadm stats. + Autocreate plugin creates/subscribes mailboxes physically only when the mailbox is opened for the first time. Mailbox listing shows the autocreated mailboxes even if they don't physically exist. + Password and user databases now support default_fields and override_fields settings to specify template defaults/overrides. - listescape plugin works perfectly now

[Dovecot] dovecot as an imap "client"
by David LEROUX 23 Nov '11

23 Nov '11

Hi, I need to get emails from one of my users imap account on a server which is not managed by us to his local imap mailbox. I'm almost sure that I've read some times that dovecot would be able to do that, kind of imap relay, but I can't find it again. I'm not sure to be very clear. Thanks, -- David
