[Dovecot] How do I test if the anti spam plugin is working?
by Dr Josef Karthauser 14 Apr '12

14 Apr '12

I've configured the dspam anti spam plugin, but it doesn't appear to be doing anything when I move mail between mailboxes. Can anyone help me determine what's going on? The plugin appears to be loading; at least if I don't define all the required configuration options I get a complaint in the log file. But beyond that I don't see any activity. Here's the config: babel# dovecot --version 2.1.3 The dovecot anti spam plugin config is: protocol imap { mail_plugins = $mail_plugins antispam } and plugin { antispam_debug_target = syslog antispam_verbose_debug = 1 antispam_backend = dspam antispam_signature = X-DSPAM-Signature antispam_signature_missing = error antispam_trash_pattern_ignorecase = trash;Deleted * antispam_spam_pattern = SPAM antispam_dspam_binary = /usr/local/bin/dspam antispam_dspam_args = --deliver=;--user;%n@_%d } I don't even appear to be seeing any log entries from the plugin. I've moving an email from my main mailbox into a mailbox called 'SPAM', which is how I thought that it was supposed to be triggered. Cheers, Joe

[Dovecot] Problems with Apple Mail and attachments
by Helga Mayer 12 Apr '12

12 Apr '12

Hello, has anyone experiences with the Apple mail client, to be precise : Mail 5.2? When I copy a message with an attachment from the inbox to a different folder using 'move' or 'copy' , Apple Mail does not properly display the attachment in the new folder. When I copy the same message using 'archive' the attachment shows up properly. There is no difference on the server side. We are using maildirs. The raw messages in the various folders are identical. Deleting plist on the Mac didn't help. After removing and recreation of the account (client side) the attachments are displayed correctly again. Is this an apple problem or has it got anything to do with dovecot.index.cache ? Kind Regards Helga Mayer

[Dovecot] vacation plugins for squirrelmail
by Daminto Lie 12 Apr '12

12 Apr '12

Hi, I am afraid I have a question to ask of you all. I have just completed setting up a mail server running on Ubuntu Server 10.04. It has postfix, dovecot 1.2.19, LDAP and squirrelmail as the webmail. I have also created virtual users accounts on the system through LDAP. I can send and receive mails which is great. Now, what I am trying to do is to set up a vacation auto-reply on the squirrelmail so that users who are about to go on vacation can set it up themselves. I was looking around for the vacation plugins for dovecot that I can incorporate it into squirrelmail. Any help would be very much appreciated. Thank you

[Dovecot] "doveadm mailbox status" destroys compressed messages without W= attribute
by Artur Zaprzała 12 Apr '12

12 Apr '12

I still have some old messages from previous mail server. This messages have no W= attribute either in file name or dovecot-uidlist and are compressed with gzip. Running "doveadm mailbox status -A vsize \*" will result in the following messages: doveadm(foo@domain): Error: Cached message size larger than expected (2580 > 1451) doveadm(foo@domain): Error: Maildir filename has wrong S value, renamed the file from /vmail/domain/foo/Maildir/.Sent/cur/1206550323.M125837P13306V0000000000000812I0000809E.oldname,S=2580:2,SZ to /vmail/domain/foo/Maildir/.Sent/cur/1206550323.M125837P13306V0000000000000812I0000809E.oldname,S=1451:2,SZ doveadm(foo@domain): Error: Corrupted index cache file /vmail/domain/foo/Maildir/.Sent/dovecot.index.cache: Broken physical size for mail UID 2 doveadm(foo@domain): Error: Cached message size larger than expected (2580 > 1451) doveadm(foo@domain): Error: Corrupted index cache file /vmail/domain/foo/Maildir/.Sent/dovecot.index.cache: Broken physical size for mail UID 2 doveadm(foo@domain): Error: read(/vmail/domain/foo/Maildir/.Sent/cur/1206550323.M125837P13306V0000000000000812I0000809E.oldname,S=2580:2,SZ) failed: Input/output error (uid=2) (Size of uncompressed message is 2580 and compressed size is 1451) I have enabled zlib plugin for imap, pop3, lda and lmtp.

[Dovecot] SSL Certificate Anomalies with latest code changes
by Thomas Leuxner 12 Apr '12

12 Apr '12

Some change between bf5ae73e9475 and 584bd77c38fd seems to have broken something in the SSL Handshake. A previously valid server certificate is deemed invalid by various mail clients. http://hg.dovecot.org/dovecot-2.1/rev/bf5ae73e9475 works fine while http://hg.dovecot.org/dovecot-2.1/rev/584bd77c38fd does not.

[Dovecot] ldap idle connection timeout in DoveCot 1.0.13?
by Zhou, Yan 12 Apr '12

12 Apr '12

Hi there, We are using DoveCot 1.0.13, it connects to LDAP server for authentication. It seems that DoveCot keeps the idle LDAP connection open. Our firewall is terminating these connections after some time of idle activity (2 hours), then, we run into authentication problem. If we restart either LDAP or DoveCot, then it is fine. Can we set some kind of LDAP idle connection timeout in DoveCot? /etc/dovecot-ldap.conf. I do not see any configuration available for 1.0.13. Another alternative is to set idle connection timeout in LDAP, but we prefer doing that in DoveCot.

[Dovecot] lazy_expunge questions
by James Devine 11 Apr '12

11 Apr '12

I'm messing around with lazy expunge and I just had a couple of questions. If I delete messages or folders with messages, I see them being moved to the expunge namespace, but if I delete an empty folder, all traces of it seem to disappear. Is there a way to move empty folders to the expunge namespace also? My second question is in regards to restoring folders. If I try to execute the imap command 'RENAME EXPUNGED/TEST INBOX/TEST' I get 'NO [CANNOT] Can't rename mailboxes to/from expunge namespace'. Just wondering if this is possible or do I need to recreate the folder and then move messages into it.
