[Dovecot] Deleting a message through IMAP
by Doug Eubanks 28 Dec '04

28 Dec '04

I have been having a problem with the test releases...I am now using Test 59. When I delete a message using SquirrelMail (IMAP) the message stays in the message list....but you can't open it anymore because it can't be found, if I logout and log back in...the message is gone from the list. I thought it could be a problem with the cache, so I added mail_never_cache_fields = MessagePart Envelope Body only to recieve Dec 24 09:23:34 news dovecot: IMAP(admin): mail_never_cache_fields: Invalid cache field name 'Body', ignoring Any ideas? This problem has plagued me for a while and I always go back to using the and older test like 22 and the problem isn't there... Doug

[Dovecot] Moving existing MD5 passwords to LDAP?
by Ben Beuchler 28 Dec '04

28 Dec '04

I have a dovecot installing working quite well for around 1000 users using passwd-file authentication. I'm moving to LDAP and would sure love to be able to migrate the existing MD5 passwords. I've tried using ldapmodify to set "userPassword" to {CRYPT}$1$H8JE0k5X$y.ptShgYbOgWF.99lX88N1 and {MD5}$1$H8JE0k5X$y.ptShgYbOgWF.99lX88N1 In both cases, ldapmodify exits without errors but I cannot bind using the new password. Any ideas? -Ben -- Ben Beuchler There is no spoon. insyte(a)emt-p.org -- The Matrix

[Dovecot] bidirectional synchronization of dovecot-managed maildirs
by James Leifer 28 Dec '04

28 Dec '04

Hello and happy holidays, I've been thinking about high performance bidirectional synchronizing the mail on my laptop (which is frequently disconnected) and my workstation at work (which is always on and receives all inbound mail). Both run dovecot on top of maildir. I've been playing with offlineimap, unison (which I already use for all my non-mail files), as well as the gnus agent (in IMAP "disconnected mode"). None of these solutions is really satisfactory: * offlineimap treats a message refile between folders as a delete-plus-resend; * unison doesn't understand the semantics of flag changes at the end of files in maildirs; it also has to stat all the files (which can become slow) to detect changes; * gnus agent can't refile messages between folders when in disconnected mode. Perhaps there are better disconnected IMAP modes available for other MUAs, but, it seems like a more general solution would be appropriate. In particular, the "uniq" field of a maildir filename is an easy way of tracking the identity of a message as it gets refiled. My question: would it be difficult to patch dovecot so that it maintained the *same* uniq when copying messages between folders? What about adding hooks that get triggered whenever dovecot copies or deletes messages? These hooks could log the changes. Later, when one tries to sync, one merges the changes from both replicas and then applies them. I'm aware that dovecot has an option to do copies as hardlinks, which is a good start, but still requires one to stat the files to discover which have the same inode. This is *much* slower than simply listing the directories and comparing maildir "uniq" fields. I'm aware that this invariant wouldn't be maintained if other programs modified the maildirs under dovecot's nose, but I'm willing to exclude this possibility. Suggestions? Best regards, -James Leifer

[Dovecot] dspam plugin
by Johannes Berg 27 Dec '04

27 Dec '04

The first version is available at http://johannes.sipsolutions.net/edit/Projects/dovecot-dspam-integration/co… I'm calling dspam for every message, that seemed easier for now. I will probably integrate Tom's idea about storing the messages until a cron-job picks them up at night by just storing signatures into mysql, in which case its easy to do with a single query: INSERT INTO new_spam (user, signature, isspam) VALUES (<user>, <signature>, <isspam>) ON DUPLICATE KEY UPDATE isspam = <isspam> with given values for <user>, <signature> and <isspam> and a key on (user, signature). For now, however, calling dspam for every message works good enough for me, and seems to work. Regards, Johannes

[Dovecot] Worthwile to use quotas?
by Peter Clark 24 Dec '04

24 Dec '04

I'm aware that dovecot doesn't support Maildir++ quotas yet (pity). However, is it still worthwhile to set up something like Postfix + Maildrop to use quotas, or is dovecot's lack of support just going to throw a wrench in the works? Thanks, :Peter

[Dovecot] Purging /var/mail/username ?

Dovecot is delivering mail to my ~/.mail directory wonderfully. But /var/mail/michael is growing steadily. Is it the job of Dovecot to purge this file regularly? Is there a setting somewhere for this? Thanks, Michael

There's good reasons to use Maildir, and there's good reasons to stay with mbox, but avoiding /var/mail is not one of them. mbox is the "classical" format, and Timo (I assume) chose to setup dovecot to use the "classical" location scheme as well, which is to store incoming mail below /var/mail and let users pull it from there and store it however they want at their personal folder below /home. If you are new to all this, actually there is probably a good point in staying close to the "classical" way of doing things, so that you can get help from more sources. I suggest keep receiving mail below /var/mail as mbox files, and play around with mbox and Maildir storage for different (test-)users below /home. Good luck, whatever you choose. - Jonas - -- * Jonas Smedegaard - idealist og Internet-arkitekt * Tlf.: +45 40843136 Website: http://dr.jones.dk/ - Enden er nær: http://www.shibumi.org/eoti.htm -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.5 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://enigmail.mozdev.org iD8DBQFByw6+n7DbMsAkQLgRAuj3AJ9QuWo3RD3NXCQV+tq0PH4+K4o4FgCeLTCE 2WASXMMup7CbMQwWn8+btjQ= =rF9V -----END PGP SIGNATURE-----

[Dovecot] error when popping mail over DSL
by Jeff Ramsey 23 Dec '04

23 Dec '04

Hi, I have a user who is getting a strange error when popping his mail over a DSL line. The error in my log file is as follows: file client.c: line 237 (client_send_line): assertion failed: ((size_t)ret == str_len(str)) I can POP his mail just find here locally connected to the server via 100bT, but over his DSL link, he gets this error. His mailbox size is 24MB, and he is using outlook w/ the option 'leave a copy of messages on the server'. He has Outlook 2003 and we use Dovecot 1.0 test 42. Is there a timeout limit on the pop3 server? -- Jeff Ramsey MIS Administrator Tubafor Mill, Inc.

[Dovecot] Need subfolders - convert to Maildir & how?
by Michael Hipp 22 Dec '04

22 Dec '04

I just installed Dovecot and it is working great. But I need subfolders. Does this mean I need to convert to Maildir format? I found several tools to do the conversion, but is there anything that needs to be changed in Dovecot to make the switch? Any advice appreciated. Thank you, Michael Hipp Heber Springs, AR, USA
