[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.. When I send an email to this user I get the following: Mar 16 09:52:11 magenta postfix/local[19065]: warning: connect #1 to subsystem private/dovecot: Connection refused Mar 16 09:52:12 magenta postfix/local[19064]: warning: connect #5 to subsystem private/dovecot: Connection refused I've the following on my /etc/postfix/main.cf ## deliver with dovecot dovecot_destination_recipient_limit = 1 mailbox_transport = dovecot smtpd_sasl_auth_enable = yes smtpd_client_restrictions = permit_sasl_authenticated I hope you can give me a hand on this :) If you need further information, please let me know (perhaps I forgot something) Best Regards Daniel -- Daniel Grilo Partner of Grupo PDM Av.

[Dovecot] public folders grayed out
by Harald Dunkel 16 Mar '10

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?

Does dovecot honor a date-time passed during APPEND?

[Dovecot] Fatal: open() failed for /var/run/dovecot/login: Permission denied
by Andy Yen 15 Mar '10

15 Mar '10

I keep getting this message when I try to start dovecot using the -F option. Fatal: open() failed for /var/run/dovecot/login: Permission denied Checking /var/run/dovecot/login folder permissions does not seem to indicate anything wrong as root has all the permissions it needs. If I am not mistaken, dovecot can run as root while in the login directory correct? When I try to start the dovecot service, it fails with the message: dovecot dead but subsys locked. Can anybody help me resolve this issue? I am running RHEL5.4. Thanks in advance.
