[Dovecot] Upgrading Dovecot on CentOS 4, from 0.99 to 1.x
by Josep L. Guallar-Esteve 24 Sep '09

24 Sep '09

Hello, We have a production mail server running dovecot 0.99 (dovecot-0.99.14-1.rf). We are getting several errors corrected in dovecot 1.x versions: * corrupted inboxes (garbage at beggining of mbox files), * corrupted index files (Error: Corrupted file index /home/jsmith/.imap/Drafts/.imap.index: Sequence 6 not found from binary tree (6 msgs says header)), * others (Error: fcntl() failed with mbox file /var/mail/jsmith: Resource deadlock avoided), etc. I'm planning to upgrade using the instructions found at dovecot's wiki. -- Josep L.

[Dovecot] Dovecot LDA, quota, sieve
by Jacek Osiecki 24 Sep '09

24 Sep '09

Hi, While moving services to a new server, I finally decided to switch from exim + procmail delivery to exim + dovecot-LDA (dovecot 1.2.5). All accounts are virtual - their settings are stored in mysql. This also includes configuring Quota and Sieve. So... there come some doubts: 1. Using "deliver" As I see, deliver uses auth-master socket to retrieve the mailbox settings (especially mailbox location). So, enabling dovecot-auth socket is everything I need to enable dovecot-LDA (apart from the exim configuration, which is explained quite clearly in wiki)? 2. Autocreation of mail folders Is it possible somehow to automatically create folders (like Trash, Sent-mail etc.)? 3. quota and its dict file. map { pattern = priv/quota/storage table = popbox username_field = username value_field = bytes } map { pattern = priv/quota/messages table = quota username_field = username value_field = messages } First - what is the "username_field" here? I'm running multiple domains, so will it be just username@domain? And - if so - is it possible to use the existing tables? I mean, that in my configuration I have a table named "popbox" with fields "local_part", "domain_name" and "quota". It would be perfect to make use of it, but either I could not find the solution or it simply requires an extra table... Hope someone will be able to help :) Best regards, -- Jacek Osiecki joshua(a)ceti.pl GG:3828944 I don't want something I need. I want something I want.

[Dovecot] windows imap clients
by Charles Sprickman 24 Sep '09

24 Sep '09

All, This is slightly OT, but I figure a bunch of folks running IMAP servers should have some strong opinions on the topic. While working on a migration to Dovecot, I had the opportunity to move one account to a server running same. This is an in-house billing department box that 3-4 people share. In theory, this should work well - all the billing folks see the same email, save sent mail to the same place, have the same set of folders available, and concurrent access is no problem. In practice, I'm finding most clients kind of suck. They started with Outlook, and that did not work well. The list of problems is long. They've been using Thunderbird for some time and I'm finding the following issues there: -searches across 2GB+ of mail are painfully slow, since it's all server-side -while the inbox is checked regularly and automatically, other folders are not unless the user manually checks them. getting tbird to do this involves a fairly non-intuitive process, and there's also the issue of making sure everyone actually adds the folders they need to watch -the client does not deal well with large amounts of mail in general - some operations give no feedback, like expanding large sub-folders or doing large copy/move operations. this leads to the user quitting the app and starting the whole process again. dovecot deals with this more gracefully than the old server (Courier), but it's still an issue -offline operation would be handy sometimes, but tbird has no "hybrid" mode, and again, one must select every folder for offline access As much as people like to bash it, OS-X mail.app is basically what I'm looking for. It addresses all the shortcomings in Tbird. If I tell it to make messages available offline, it does that for all boxes. It always checks all my boxes, and when a search is performed it searches on the local copy rather than the server (which is quite polite, IMHO). It works quite well with no internet connection as well. I have about 50,000 messages in it now across 5 accounts and it only rarely gets laggy on me. I want this client on Windows, basically. :) I'm installing Mulberry now, but the manual seems to indicate it also will rely on the server-side search unless it's in offline mode (which has to be toggled - not a good solution). I must say, Dovecot has impressed the hell out of me. I had a chance to deal with the same mailbox in courier and dovecot, and everything is much faster, especially in mail.app and roundcube. Insanely fast... What else is out there for windows clients? Thanks, Charles ___ Charles Sprickman NetEng/SysAdmin Bway.net - New York's Best Internet - www.bway.net spork(a)bway.net - 212.655.9344

[Dovecot] Solr Plugin make only INBOX able to search
by rui.carneiro＠portugalmail.net 23 Sep '09

23 Sep '09

Hi all, I have downloaded and installed dovecot 1.2.4 with Solr plugin. After that, when I try to do some searches the results are weird. All messages that aren't on INBOX folder are ignored. For example, if I have a folder named "Test Folder", when I try to do ". search text <string>" the result is always empty. I tried TEXT, SUBJECT and BODY arguments and none of them returned any email. Any idea of the problem's source? Regards, Rui Carneiro

[Dovecot] SharedMailboxes in a distributed environment
by Christian Rohmann 23 Sep '09

23 Sep '09

Hello folks, I'd like your thoughts on the following problem: If one is using v1.2+ IMAP ACLs to allow users to share their mailbox and uses SQL as dictionary backend, every dovecot server would know which ACLs to enforce. But as the wiki states here "http://wiki.dovecot.org/SharedMailboxes/Shared" dovecot needs access to the other mailbox. Does that automatically mean that one dovecot machine needs to have filesystem access to the all mailboxes that are to be shared? Is there no way to share mailboxes (folders) between different servers? (apart from using NFS i.e.) -- Christian Rohmann Content Delivery Server u.

[Dovecot] shared/public mailbox doesn't exist
by Eric Shubert 22 Sep '09

22 Sep '09

I have 3 servers running dovecot 1.0.10. 2 of them are configured with a shared/public namespace, but I'm having trouble getting it to work on the third, even with 2 working examples to go by. There's something I'm missing, and I'm hoping that someone here can see/tell what it is. I've created the maildir for sharing: # cd /home/vpopmail/domains/mydomain.com # maildirmake shared # chown -R vpopmail:vchkpw shared Then added the configuration to dovecot.conf: # shared namespace namespace shared { separator = . prefix = shared. location = maildir:/home/vpopmail/domains/mydomain.com/shared } Restarted dovecot: # service dovecot restart When I try to subscribe to the shared namespace though with Outlook, I get: "Failed to subscribe the folder. Server responded: 'Mailbox doesn't exist: shared'." When I try to subscribe with Squirrelmail I get: "ERROR: Could not complete request. Query: SUBSCRIBE "shared" Reason Given: [TRYCREATE] Mailbox doesn't exist: shared" I've tried various combinations of permissions to no avail. Suggestions welcome. I'm at my wits end. -- -Eric 'shubes'
