[Dovecot] Ways to poke and prod Dovecot?
by leam hall 21 Aug '12

21 Aug '12

I'm a newbie and want to learn more about Dovecot. I can install it in a test bed but am not sure how to run it so it shows me what it's doing but i'm not actually mailing stuff. Is there a doc somewhere? Thanks! Leam -- Mind on a Mission <http://leamhall.blogspot.com/>

[Dovecot] Search extensions
by Timo Sirainen 21 Aug '12

21 Aug '12

I'm thinking about adding at least one new SEARCH command extension to Dovecot: ability to search from any headers in the mail, including MIME headers in the body. So the idea is that you could somewhat quickly ask e.g. "show me all mails with pdf attachments": a search or x-anyheader application/pdf x-anyheader .pdf b fetch $ bodystructure The client can verify the results with the fetch. The "x-anyheader" can already be implemented without changes to full text search plugin, because all backends store message/MIME headers and body text separately. So, questions for the list, especially client developers: 1) What's a better name for x-anyheader? :) 2) Any other ideas about search extensions you'd want to see? Maybe I could get this standardized at some point. I think one other thing missing has been "show me messages that have attachments". I've thought about maybe creating a $hasattachments keyword for that, which the server could automatically set for new mails that it thinks has attachments (and clients can set/unset the keyword if wanted).

[Dovecot] Spaces in DN with AD auth
by Chris Visser 21 Aug '12

21 Aug '12

Hi guys, I'm back to fiddling with my Dovecot and AD intergation and I've noticed that if a DN contains spaces, dovecot doesn't bind to the AD server. I'm running: dovecot-2.1.1 exim-4.72 on CentOS 6.3 Exim binds fine with the DNs containing spaces, it's just dovecot that exhibits the symptoms.

[Dovecot] namespace from snapshots
by Karl Oulmi 21 Aug '12

21 Aug '12

hi all, I'm trying to give access to snapshots taken from by dell iscsi MD3200i to my maildirs users. snapshot are mounted in read only mode from my FreeBSD box. In my /usr/local/etc/dovecot/conf.d/10-mail.conf, I have : namespace inbox { inbox = yes } namespace da1 { prefix = INBOX.backup.da1. hidden = no list = yes inbox = no location = maildir:/da1/%u/Maildir type = private } I have two problems : - In my log, dovecot complain about the fact that my snapshot filsystem is read only Error: open(/da1/test2(a)toto.com/Maildir/.Trash/dovecot-uidlist) failed: Read-only file system The second problem is that through my thunderbird I can't see the Inbox saved in the snapshot (whereas I see Sent and Trash folders) If anyone could help me, It would be nice. Regard, Karl.

Re: [Dovecot] Hostname Based forwarding

Merrickville <merrickville(a)gmail.com> writes: > Is there a way to proxy based on the host name the client has configured in > his/her email client? (Like Apache VirtualHosts) I doubt it; the virtual name is not part of the IMAP protocol as it is in HTTP. The IMAP server is not told which hostname was mapped to its IP. You'll either have to add the @domain, or perhaps multi-home your host, remap one of your domains to the new IP, and add another running instance of dovecot to listen on that interface.

[Dovecot] Full text search in attachments
by Mailing 20 Aug '12

20 Aug '12

Hello, is it possible to use the Solr full text search plugin for indexing mail attachments? I found a very old patch and some hints regarding a fts_decoder script that I don't understand. Making Solr indexing PDF or Office files shouldn't be that difficult, but how can I enable the plugin to transfer the attachments to Solr? Best regards, Sebastian

[Dovecot] case insensitive acl
by Andre Rodier 19 Aug '12

19 Aug '12

Hello, I have notice that when I use ACL, the name of the user in the dovec-acl-list file is case sensitive. Because I use LDAP, the name of the users is case insensitive. Would it be possible to have an option in Dovecot, to ignore the case of the ACL ? This would be useful with some ACL managers, like roundcube ACL plugin, that uses an LDAP query to autocomplete the user name for the ACL. Kind regards, André

[Dovecot] Mdbox corruption

Hi, I have a "ubuntu10.04 + ext4-filesystem + dovecot-2.0.13 +mdbox" configuration in my server. It works fine with ~50k accounts. Recently happened a filesystem corruption in a device of StMailLocation and I fix with fsck.ext4. After this crash, one account began to show access timeout and errors like this on force-resync: # doveadm force-resync -u account INBOX doveadm(account): Warning: mdbox /path-to-mdbox/storage: rebuilding indexes doveadm(account): Error: Corrupted dbox file /path-to-mdbox/storage/m.83 (around offset=16): EOF reading msg header (got 0/30 bytes) doveadm(account): Warning: dbox: Copy of the broken file saved to /path-to-mdbox/storage/m.83.broken doveadm(account): Error: Corrupted dbox file /path-to-mdbox/storage/m.83 (around offset=16): EOF reading msg header (got 0/30 bytes) doveadm(account): Error: mdbox rebuild: Failed to fix file /path-to-mdbox/storage/m.83 doveadm(account): Error: Corrupted dbox file /path-to-mdbox/storage/m.92 (around offset=7): Invalid dbox version ...
