Did you try looking for the folders by connecting to IMAP using command line. telnet servername 143 a1 login username pass a2 list "" * Check if you could see anything.

[Dovecot] Missing IMAP folders after Server reboot
by Eoin Kennedy 31 May '09

31 May '09

Hi, Here is the situation, I hope somebody can help me. Our Email server running ubuntu 8.04.1 and dovecot 1.0.10 rebooted, and when it came back up the dovecot config had changed. Prior to the reboot, users stored their emails and folders in /var/mail/~username. Then the config became /var/mail/username for the main Inbox and /home/~username/mail for Folders. Now, none of the folders that users had created in their IMAP account are visible, and their contents are not in the main Inbox file. For example, the Drafts folder was there prior to the reboot, and now it had to be created in /home/username afterwards. These folders were not subfolders of the Inbox, but of the main IMAP root. All users were running Thunderbird as their client. Can they be recovered? Thanks, Eoin Kennedy ----------------------------------------------------------------------------- Sherling & Sons Ltd, Jamestown Road, Inchicore, Dublin 8, Ireland.

[Dovecot] antispam plugin and MUA-Junk folders
by Steffen Kaiser 31 May '09

31 May '09

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, I have a configuration problem, that I ignored till now. Many MUAs tag SPAM themselves and move SPAM to a junk folder (Thunderbird uses "Junk"). It is said to not automatically train these mails, but let have an human revise them. Currently, I have configured those folders as "trash" folders for antispam, which means that those messages are essentially lost, because a move into a spam folder will not train them. -> The current antispam plugin ignores moves in and out of trash folders completely. I wonder why the move trash -> SPAM is ignored? If I configure those junk folders as "unsure" in antispam, the situation can happen, that an user selects a spam folder, the MUA identifies junk and moves the messages into its Junk folder. Current implementation would train this move as HAM. How about the following: 1) copy from * into trash or unsure -> not train 2) copy from !spam into spam -> train as SPAM 4) copy from spam or unsure into !(trash or unsure or spam) -> train as HAM 6) else -> not train Bye, - -- Steffen Kaiser -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) iQEVAwUBSh0PdHWSIuGy1ktrAQKmaAf/ew1SixCkkWD2V12Jfw3mLcWnUrUSRq/J nsyMkW2//tX74wSJeMjbzlEkxN3dyfJg7f4WviGPdnUp5sqNGuS9lBfHh3ShQHtt 30+mRzVqizmcNEXBFoZXVy1K5hE8p9ssN9avahmUejBVPaSZHD0OjN5h8nFkNMDI XHU2347g03zr1MxejinWyRiKt1MFQyyJ6Y7gXNf6yascWKJA8W6b4Zu/eIH5uEW+ yiMuweaxJOwuGcwqh/qSKZTXnoCLa9rzvd8i/uZGvn7AXoT5u4P5coZkIHrh64U7 oswuYAZwxkmjGNLdGrovZadRJym16BlfVHH5g3Zo7k4nwX+kGRKyug== =9b+n -----END PGP SIGNATURE-----

[Dovecot] offlineimap with dovecot and sieve
by Dieter Faulbaum 29 May '09

29 May '09

I have a dumb question, is it possible to use this combination: Synchronising a remote IMAP-server and a local dovecot-IMAP-server by offlineimap (with both types = IMAP), which works very well. But it seems, that my sieve-scripts on the local dovecot server are not recognised by this combination. Is there a good debugging way for this? -- Dieter Faulbaum Elektronenspeicherring BESSY II Albert-Einstein-Str. 15, 12489 Berlin phone +49 30 6392-4652 fax +49 30 6392-2939 mail Dieter.Faulbaum(a)bessy.de

[Dovecot] (no subject)
by Patrick Hemmen 29 May '09

29 May '09

Hi, I use a OpenLDAP for authentication. To authenticate a full DN as the user name must be used, like "cn=jim,ou=users,dc=example,dc=com". There are several domains, like example2.com and example3.com. I want to use Dovecot with ldap and authentication binds. For testing I use "auth_bind_userdn = cn=%n,ou=users,dc=%d" and the user name must provide as "jim@example,dc=com". To allow the special chars ("=,") in user name, I extend "auth_username_chars". Now my questions. Exists a real chance to attack the ldap directory with the extended "auth_username_chars"? And it's possible to use authentication binds with the regular "auth_username_chars" and a provided user names like "jim(a)example.com" in my special ldap directory structure? Thanks in advance - Patrick

[Dovecot] Clustering dovecot?
by dovecot＠corwyn.net 29 May '09

29 May '09

Currently I have a mail server running postfix and dovecot with users in mysql. I have Outlook (blich) clients checking IMAP mail on the server. I'd like to build some fault-tolerance into that system in case I have hardware failure. I've read through: http://wiki.dovecot.org/MailLocation/SharedDisk but I feel I need more information. My basic understanding is that I'll need 2 clustered systems running with shared disk space and shared IP. Performance/load-balancing isn't an issue for me, it's just fault-tolerance that I'm worried about. I found a nice long doc for Cyrus IMAP (http://cyrusimap.web.cmu.edu//ag.html) anything similar for dovecot? Rick Rick Steeves http://www.sinister.net "The more I learn, it seems, the less I know."

[Dovecot] expire: mysql table creation error
by John Fawcett 28 May '09

28 May '09

Don't know if anyone found this already (couldn't see anything in the archives about it) but maybe this is useful to someone else who finds the same problem. When following the instructions for setting up expire on v1.2+ for mysql backend at http://wiki.dovecot.org/Plugins/Expire I got the following error: mysql> CREATE TABLE expires ( -> username varchar(100) not null, -> mailbox varchar(255) not null, -> expire_stamp integer not null, -> primary key (username, mailbox) -> ); ERROR 1071 (42000): Specified key was too long; max key length is 1000 bytes that's because it's a utf8 database where every char is 3 bytes so a 355 char index is 1065 bytes. it worked ok with the following modification: mysql> CREATE TABLE expires ( -> username varchar(100) not null, -> mailbox varchar(255) not null, -> expire_stamp integer not null, -> primary key (username, mailbox(200)) -> ); Query OK, 0 rows affected (0.00 sec) but maybe that's not such a good primary key, probably better to do: mysql> CREATE TABLE expires ( -> id integer not null auto_increment, -> username varchar(100) not null, -> mailbox varchar(255) not null, -> expire_stamp integer not null, -> primary key (id), -> key (username, mailbox(200)) -> ); Query OK, 0 rows affected (0.00 sec) John
