[Dovecot] connecting postfix with dovecot trouble
by André Höpner 03 May '07

03 May '07

Hello listmembers, we have some trouble connecting postfix to dovecot. after a lot of hours the transport and delivery is working but dovecot can't get the correct user. postmap -q some.user(a)domain.com ldap:/etc/postfix/ldap-aliases.cf first returns: someuser The mailbox someuser exists and i can login with this user on imap and i can deliver directly using deliver -d but on mail delivery thrue postfix dovecot is not looking for someuser. It looks for someuser(a)host.domain.com. ---8<------ May 3 16:18:42 mail postfix/pickup[24686]: C94251DB23E: uid=0 from=<root> May 3 16:18:42 mail postfix/cleanup[24769]: C94251DB23E: message-id=<20070503161842.C94251DB23E(a)host.domain.com> May 3 16:18:42 mail postfix/qmgr[24544]: C94251DB23E: from=<root(a)host.domain.com>, size=322, nrcpt=1 (queue active) May 3 16:18:42 mail dovecot: auth(default): master in: USER 1 someuser(a)host.domain.com service=deliver May 3 16:18:42 mail dovecot: auth(default): ldap(someuser(a)host.domain.com): user search: base=dc=domain,dc=com scope=subtree filter=(&(objectClass=posixAccount)(uid=someuser(a)host.domain.com)) fields=mail,homeDirectory May 3 16:18:42 mail dovecot: auth(default): master out: USER 1 someuser(a)host.domain.com home=/var/mail/dovecot/someuser uid=100 gid=12 May 3 16:18:42 mail postfix/pipe[24772]: C94251DB23E: to=<someuser(a)host.domain.com>, orig_to=<some.user(a)domain.com>, relay=dovecot, delay=0.04, delays=0.02/0.01/0/0.02, dsn=2.0.0, status=sent (delivered via dovecot service) May 3 16:18:42 mail postfix/qmgr[24544]: C94251DB23E: removed ---8<------ It seems that postfix or dovecot appends the hostname to the mailboxname. But i cant figure out which of both. If i change the uid to someuser(a)hostname.domain.com on ldap-server anything works fine. how can i fix this? i dont know if anyone needs config files for diagnostic. if so - please tell me and i post the needed informations. best regards Andre Hoepner

[Dovecot] Any plans for storing messages on a database?
by Francisco Reyes 03 May '07

03 May '07

Redudancy and recovering from a mailstore failure is one of the concerns I am trying to address where I work. Any plans to have Dovecot store emails in a database? NAS/SAN devices which do automatic replication to a second device are extremely expensive. I also don't see any distributed filesystem which is mature and available for the OS we use (FreeBSD). I recall at one point, many months back, Timo mentioned that perhaps storing the messages in the database was a possibility for the future. Any additional thoughts on this?

[Dovecot] 200 pop3-login processes
by Zbigniew Szalbot 03 May '07

03 May '07

Dear all, I am using dovecot 1.0.0 and have only 5 pop3 users. However, I have counted over 200 pop3-loging processes. I just wonder if it is normal for dovecot (has been running maybe for 2-3 weeks after installing the stable verion). Thanks! -- Zbigniew Szalbot

[Dovecot] Migrate from mlbox to maildir, lock problem
by Sylvain Nemtua 02 May '07

02 May '07

Hi We've been using dovecot successufly for few month. Previous setup : solaris 8, postfix+LDA, mbox + index on NFS (Netapp), 2500 accounts Everything shared overs NFS, multiple servers connect to index, mbox. mail_location = mbox:/var/mail/mbox/%u:INBOX=/var/mail/%u:INDEX=/var/mail/indexes_dovecot/%u We had at first some issue with mbox locking, using lock_method = dotlock solve the issue. The problem seemed to be with fcntl. I Migrate to maildir to ease administration to use maildir quota I use mb2md-3.20.pl to migrate the mbox everything works smooth. Actual setup : solaris 8, postfix+LDA, maildir + index + control on NFS (Netapp) I change the mail_location settings to mail_location = maildir:/var/mail/maildir/%u:INDEX=/var/mail/indexes_dovecot/%u:CONTROL=/var/mail/dovecot_control/%u And now I'm facing new locking issue : Errors on user loging, users leaving mail on server downloading the same mail over and over. Numerous entries in log files : May 2 11:19:03 gregorie dovecot: [ID 107833 mail.error] POP3(carini): Maildir /var/mail/maildir/carini sync: UID inserted in the middle of mailbox (13 > 1, file = 1178097228.P16222Q0M452645.yder,S=22935:2,) May 2 11:19:03 gregorie dovecot: [ID 107833 mail.info] POP3(carini): Disconnected: Mailbox is in inconsistent state. top=0/0, retr=0/0, del=0/0, s ize=0 May 2 11:19:03 gregorie dovecot: [ID 107833 mail.error] POP3(carini): Couldn't init INBOX: Internal error occurred.

[Dovecot] How to use option allow_nets?
by Bernd Kuhls 02 May '07

02 May '07

Hi, according to http://wiki.dovecot.fi/PasswordDatabase/ExtraFields/AllowNets there exists an option allow_nets to restrict IP ranges from where users are allowed to login to Dovecot. I am using Debian Etch with the official Dovecot packages: # dpkg -l | grep dovecot ii dovecot-common 1.0.rc15-2 ii dovecot-imapd 1.0.rc15-2 ii dovecot-pop3d 1.0.rc15-2 using a mostly unchanged dovecot.conf. I tried to add the line allow_nets=127.0.0.0/8,192.168.0.0/16 in the block passdb pam { which is the default enabled auth code in Debian. When starting Dovecot I get this error message: # /etc/init.d/dovecot start Starting mail server: dovecot Error: Error in configuration file /etc/dovecot/dovecot.conf line 777: Unknown setting: allow_nets According to the Dovecot changelog > 2006-02-27 18:46 Timo Sirainen <timo.sirainen(a)movial.fi> > > * src/auth/: auth-request.c, auth-request.h: Added "allow_nets" > extra field. If set, the user can log in only from within the > given networks (hope the code is correct...) the option exists since February 2006, while the Debian package was released in December 2006. What I am doing wrong? Using TCP wrappers instead seems not to be an option according to http://dovecot.org/list/dovecot/2006-April/012476.html Greetings, Bernd Kuhls

[Dovecot] Best authentication option
by Eric 02 May '07

02 May '07

Dear Dovecot experts, I have a small home server debian based, with postfix/dovecot/squirrelmail installed locally and working. Dovecot is used non-secured (no imaps) but only on the 192.168.0.100 address (address of the server on the local network). I want to use squirrelmail to read my email from outside. Squirrelmail can configured to access it in particular, either through cram-md5 or login auths. In that situation, is it better (I mean more secure) to use : 1) auth mechanim = cram-md5 or 2) auth mechanism = plain (using PAM authentication for dovecot) ? That will determine my dovecot configuration. Thank you Eric

[Dovecot] Strange directory created at dovecot launch
by Eric 02 May '07

02 May '07

I installed dovecot from scratch and compiled it from 1.0.0 source. Installed in /usr/local. Now everytime I launch dovecot it creates and uses /usr/local/var/lib/dovecot and /usr/local/var/run/dovecot directories. For the latter I found the modifications to do in dovecot.conf for using /var/run/dovecot instead, but for the former I see nothing about such directory in dovecot.conf. What happens ? How can I configure it so that dovecot uses /var/lib/dovecot instead ? Thank you Eric
