[Dovecot] Dovecot 2.0b3: mdbox with incorrect ACL file permissions crashes
by Thomas Leuxner 16 Mar '10

16 Mar '10

Hi, played around with 'mdbox' format some more. Converted my personal mailbox with latest Dovecot and dsync from HG: dsync convert -u login(a)yourdomain.com mdbox:~/mdbox One thing I noticed is, that dsync does not take care of existing 'dovecot-acl' files, which it should migrate/copy from my point of view, but simply skips them. Anyway I copied over the ACLs manually and forgot to set the rights accordingly. So the files were owned by 'root:vmail' instead of 'vmail:vmail' in my setup. Voilà Dovecot crashed, where it should really throw a warning or ignore the owner and work with the group permissions: Mar 2 19:27:52 spectre dovecot: imap(tlx(a)leuxner.net): acl vfile: file /var/vmail/conf.d/leuxner.net/acls/Support/Serverloft not found Mar 2 19:27:52 spectre dovecot: imap(tlx(a)leuxner.net): acl vfile: no access to file /var/vmail/leuxner.net/tlx/mdbox/mailboxes/Support/Serverloft/dbox-Mails/dovecot-acl Mar 2 19:27:52 spectre dovecot: imap(tlx(a)leuxner.net): Panic: file acl-cache.c: line 295 (acl_cache_update_rights): assertion failed: (obj_cache->my_current_rights != &negative_cache_entry) Mar 2 19:27:52 spectre dovecot: imap(tlx(a)leuxner.net): Raw backtrace: /usr/lib/dovecot/libdovecot.so.0 [0x7f4d8595ffb2] -> /usr/lib/dovecot/libdovecot.so.0 [0x7f4d8596001a] -> /usr/lib/dovecot/libdovecot.so.0 (i_error+0) [0x7f4d859603c3] -> /usr/lib/dovecot/modules/lib01_acl_plugin.so [0x7f4d84da690b] -> /usr/lib/dovecot/modules/lib01_acl_plugin.so [0x7f4d84da4249] -> /usr/lib/dovecot/modules/lib01_acl_plugin.so [0 x7f4d84da4572] -> /usr/lib/dovecot/modules/lib01_acl_plugin.so [0x7f4d84da472e] -> /usr/lib/dovecot/modules/lib01_acl_plugin.so [0x7f4d84da2aba] -> /usr/lib/dovecot/modules/lib01_acl_plugin.so(acl_object_get_m y_rights+0x65) [0x7f4d84da2b85] -> /usr/lib/dovecot/modules/lib01_acl_plugin.so [0x7f4d84da8fd9] -> dovecot/imap [tlx(a)leuxner.net 84.58.106.99 STATUS](client_find_namespace+0x17f) [0x41149f] -> dovecot/imap [t lx(a)leuxner.net 84.58.106.99 STATUS](cmd_status+0xfc) [0x40dc2c] -> dovecot/imap [tlx(a)leuxner.net 84.58.106.99 STATUS] [0x40f9bc] -> dovecot/imap [tlx(a)leuxner.net 84.58.106.99 STATUS] [0x40fa6d] -> dovecot/imap [tlx(a)leuxner.net 84.58.106.99 STATUS](client_handle_input+0x45) [0x40fbe5] -> dovecot/imap [tlx(a)leuxner.net 84.58.106.99 STATUS](client_input+0x62) [0x410622] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handl er_run+0xcb) [0x7f4d8596abab] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_run+0x18) [0x7f4d85969d28] -> /usr/lib/dovecot/libdovecot.so.0(master_service_run+0x13) [0x7f4d85959eb3] -> dovecot/imap [tlx(a)leuxner.n et 84.58.106.99 STATUS](main+0x191) [0x418661] -> /lib/libc.so.6(__libc_start_main+0xe6) [0x7f4d851e71a6] -> dovecot/imap [tlx(a)leuxner.net 84.58.106.99 STATUS] [0x4084e9] Mar 2 19:27:52 spectre dovecot: master: service(imap): child 30281 killed with signal 6 (core dumps disabled) Regards Thomas

[Dovecot] Shared folders
by Неворотин Вадим 16 Mar '10

16 Mar '10

I need to create a shared folder (mailbox for group mailing list) with access of several accounts to it. But all peoples with access to this mailbox should be able to work with this folder absolutely in the same way, as with local mailbox. Each user should be able to delete emails and mark it as readed. But this changes must be only for one user, not for others. For example user1 and user2 have access to folder Trades. There is a new incoming mail. User1 read it and delete. But in user2's client this mail must be not readed and not deleted. So there should be only one copy of a email (in group mailbox), but state (unreaded|readed|deleted) of this email shoud be different for each user. Can I do this with dovecot? Yes, I know that I can send a copy of group letter to each user's mailbox, but unfortunately I has a lot of groups and very big letters, so I can't duplicate each letter to many mailboxes. The purpose is to story only one instance of each letter, but to allow users to work with it like with their own letters. Now I use Maildir++ mailboxes.

[Dovecot] Quota plugin and SQL
by David 16 Mar '10

16 Mar '10

I have read through http://wiki.dovecot.org/Quota/Dict, which suggests a database schema for using quota. For 1.2, this includes a username, bytes and messages. Is there any way to modify the queries used to split out username into localpart and domain? This would enable me to put the current quota information in my main mailbox table and display it to users in my admin interface. Or possibly it should be in a separate table for a reason, and I should be look there for the values? Thanks, David

[Dovecot] extraneous mail folder created
by John Moorhouse 16 Mar '10

16 Mar '10

I'm trying to set up dovecot on a Fedora box for about 5 users, I have a raid 5 array that is used for home folders etc mounted on /home, and I've created a directory /home/mail, which I have used a sym link to map /var/mail to. I've created folders for each of the users with relevant permissions and edited the dovecote config with:- namespace private { separator = / prefix = "#dbox/" location = dbox:~/mail:INBOX=/var/mail/%u inbox = yes hidden = yes list = no # for v1.1+ } namespace private { separator = / prefix = location = dbox:/var/mail/%u/mail } This all seems to work with the exception that when a imap client attaches to dovecot an empty folder called 'mail' is created in the users home directory. so for client jenni, whist all her emails etc are stored in /home/mail/jenni/ for INBOX and /home/mail/jenni/mail/ for folders etc, an empty folder is created as /home/jenni/mail/ Any help appreciated John

[Dovecot] IMAP proxy configuration
by Leonardo Rodrigues 16 Mar '10

16 Mar '10

i know dovecot can act as IMAP and POP3 proxy ..... but i'm having a hard time configuring it. Actually i'm using a simple dovecot configuration with virtual users stored on MySQL. My dovecot-sql.conf is pretty simple: [root@correio dovecot]# cat dovecot-sql.conf driver = mysql connect = host=localhost dbname=DATABASE user=USERNAME password=PASSWORD default_pass_scheme = PLAIN # Get the mailbox user_query = select '/var/spool/mail/%u' as home, 'maildir:/var/spool/mail/%u' as mail, 8 as uid, 12 as gid, concat('*:storage=', quota) as quota_rule, 'Trash:storage=100M' as quota_rule2 from emails where endereco = '%u' and ativa = '1' # Get the password password_query = select endereco as user, password, '/var/spool/mail/%u' as userdb_home, 'maildir:/var/spool/mail/%u' as userdb_mail, 8 as userdb_uid, 12 as userdb_gid, concat('*:storage=', quota) as userdb_quota_rule, 'Trash:storage=100M' as userdb_quota_rule2 from emails where endereco = '%u' and ativa = '1' [root@correio dovecot]# i've read several docs about configuring proxy on dovecot but all of them says about proxying specific users .... i'm interested on proxying some domains. I couldnt find a way to configure that nor some howto similar to that. could anyone point me some documentation on configuring dovecot as IMAP/POP3 proxy for a full domain and not specific users ? Ideally i would have a list of domains that should be proxied to somewhere else and all the other domains would be threated locally.

[Dovecot] dovecot-2.0.beta3 does not create dovecot/login directory
by Jürgen Bereuter 16 Mar '10

16 Mar '10

Hello, i build the beta3 of dovecot 2.0 on Opensolaris (SunOS sol 5.11 snv_134 i86pc i386), restarted and dovecot logs the following error. I created the directory path /var/run/dovecot/login and voila, imap is starting up without any problems. But as soon as i reboot the PC (it is only a pseudo private server), the new directory gets deleted (as expected and planed, as fa as i know), but not to be (re)created. Not a big problem, but i think it is worth to mention it. Perhaps i am wrong and messed something completely up, in that case i would be glad to receive a clue. Thanks, bye, jürgen Permissions of /var/run/dovecot are drwxr-xr-x 4 root root 573 Mär 15 21:03 dovecot Mar 15 20:12:54 imap-login: Info: Login: user=<xxxxxx>, method=PLAIN, rip=xx.xx.xx.xx, lip=10.0.0.5 Mar 15 20:25:22 imap(jub): Warning: Killed with signal 15 (by pid=846 uid=0 code=kill) Mar 15 20:25:22 imap(jub): Info: Server shutting down. bytes=31/428 Mar 15 20:25:22 imap(jub): Warning: Killed with signal 15 (by pid=846 uid=0 code=kill) Mar 15 20:25:22 imap(jub): Info: Server shutting down. bytes=1071/3075 Mar 15 20:25:22 imap(jub): Warning: Killed with signal 15 (by pid=846 uid=0 code=kill) Mar 15 20:25:22 imap(jub): Info: Server shutting down. bytes=504/1548 Mar 15 20:25:22 imap(jub): Warning: Killed with signal 15 (by pid=846 uid=0 code=kill) Mar 15 20:25:22 imap(jub): Info: Server shutting down. bytes=1176/1090254 Mar 15 20:25:22 log: Warning: Killed with signal 15 (by pid=846 uid=0 code=kill) Mar 15 20:25:22 master: Warning: Killed with signal 15 (by pid=846 uid=0 code=kill) Mar 15 20:26:48 master: Error: opendir(/var/run/dovecot//login) failed: No such file or directory Mar 15 20:26:51 master: Error: bind(/var/run/dovecot//login/ssl-params) failed: No such file or directory Mar 15 20:26:51 master: Error: bind(/var/run/dovecot//login/imap) failed: No such file or directory Mar 15 20:26:51 master: Error: bind(/var/run/dovecot//login/dns-client) failed: No such file or directory Mar 15 20:26:51 master: Error: bind(/var/run/dovecot//login/auth) failed: No such file or directory Mar 15 20:26:51 master: Fatal: Failed to start listeners Mar 15 20:26:51 master: Error: opendir(/var/run/dovecot//login) failed: No such file or directory Mar 15 20:26:51 master: Error: bind(/var/run/dovecot//login/ssl-params) failed: No such file or directory Mar 15 20:26:51 master: Error: bind(/var/run/dovecot//login/imap) failed: No such file or directory Mar 15 20:26:51 master: Error: bind(/var/run/dovecot//login/dns-client) failed: No such file or directory Mar 15 20:26:51 master: Error: bind(/var/run/dovecot//login/auth) failed: No such file or directory Mar 15 20:26:51 master: Fatal: Failed to start listeners Mar 15 20:26:52 master: Error: opendir(/var/run/dovecot//login) failed: No such file or directory Mar 15 20:26:52 master: Error: bind(/var/run/dovecot//login/ssl-params) failed: No such file or directory Mar 15 20:26:52 master: Error: bind(/var/run/dovecot//login/imap) failed: No such file or directory Mar 15 20:26:52 master: Error: bind(/var/run/dovecot//login/dns-client) failed: No such file or directory Mar 15 20:26:52 master: Error: bind(/var/run/dovecot//login/auth) failed: No such file or directory Mar 15 20:26:52 master: Fatal: Failed to start listeners

[Dovecot] Courier to dovecot migrations
by Daniel Grilo 16 Mar '10

16 Mar '10

Dear All, I saw some topics discussed in forums about this, but none with my problems :( Currently we have a mailserver postfix with courier-imap-4.1.1, and courier-pop3 and courier-authlib. Our Maildir's are written in the users home directory (ex: ~/Maildir) I'm now migrating the mailserver to other cluster and installing with dovecot. We're also moving the Maildir's to other directory (ex: /opt/mailboxes/%u) I've ran your perl script courier-dovecot-migrate-1.0.pl which worked just great (as far as I can tell from the OK messages) .. but when configuring my mail client for this account I get the following: Mar 16 09:49:27 magenta dovecot: auth(default): master out: USER 69 scanner system_user=scanner uid=734 gid=100 home=/home/scanner Mar 16 09:49:27 magenta dovecot: imap-login: Login: user=<scanner>, method=PLAIN, rip=::ffff:192.168.1.210, lip=::ffff:192.168.1.110 Mar 16 09:49:27 magenta dovecot: IMAP(scanner): Effective uid=734, gid=100, home=/home/scanner Mar 16 09:49:27 magenta dovecot: IMAP(scanner): maildir: data=/opt/mailboxes/scanner Mar 16 09:49:27 magenta dovecot: IMAP(scanner): maildir: root=/opt/mailboxes/scanner, index=/opt/mailboxes/scanner, control=, inbox= Mar 16 09:49:27 magenta dovecot: IMAP(scanner): stat(/opt/mailboxes/scanner/cur) failed: Permission denied Mar 16 09:49:27 magenta dovecot: IMAP(scanner): stat(/opt/mailboxes/scanner/cur) failed: Permission denied [root@magenta ~]# ls -la /opt/mailboxes/ total 36 drwxrwx--- 4 root dovecot 4096 Mar 15 11:49 . drwxr-xr-x 6 root dovecot 4096 Mar 9 2009 .. drwxrwx--- 2 root root 16384 Feb 10 15:55 lost+found drwx------ 9 scanner users 4096 Mar 15 11:56 scanner The second problem is between postfix / dovecot..

[Dovecot] public folders grayed out

Hi folks, I have configured a public folder as described on the Wiki (more or less; see below), but in TB3 I see the "Public" folder grayed out. I cannot subscribe. Toggling the subscriptions flag doesn't help. What did I miss here? Any helpful comment would be highly appreciated. If this is a TB3 problem: Which MUA would you suggest?
