[Dovecot] Dovecot 2.0.2 breakes LMTP delivery for me
by Fabian Ruff 13 Sep '10

13 Sep '10

Hi, I'm onboard Debian Lenny (amd64) and just reverted from 2.0.2-0~auto+4 back to 2.0.1-0~auto+1 because LMTP stopped working completly with the above Package. In my setup delivery is done from exim via LMTP to dovecot (Maildir/ext3). The lmtp dovecot config looks like this: > service lmtp { > user = vmail > inet_listener lmtp { > address = 127.0.0.1 > port = 24 > } > > unix_listener lmtp { > } > } > protocol lmtp { > hostname = [...].de > mail_plugins = sieve quota listescape > postmaster_address = postmaster@[...].de > } With the new version I get no LMTP log message at all from dovecot and Exim fails with: > LMTP timeout after initial connection When I do "/etc/init.d/dovecot stop" some process remain alive and I ultimately have to SIGKILL the lmtp process to get rid of it. > trench:/tmp# ps auwx |grep dovecot > root 2643 0.0 0.0 8224 768 pts/1 R+ 22:50 0:00 grep dovecot > root 31778 0.0 0.0 12384 684 pts/2 S+ 22:36 0:00 tail -f > /var/log/mail/dovecot.log > dovecot 32368 0.0 0.0 12656 996 ?

Any ideas whats the Problem? Could there be a regression from the LMTP fixes introduced in 2.0.2? Cheers, Fabian Ruff

[Dovecot] Certificate for outlook 2003
by Richard Gliebe 13 Sep '10

13 Sep '10

Hi all, We are running "dovecot-1.0.7-7.el5" on a CentOS release 5.5 (Final) box. I know, its an old version, but it cames up with the CentOS release (yum). Anyway. Is there a way to import the certificate, which was generated with "mkcert_dovecot.sh", permanently to the outlook 2003 clients? Every time, when our office 2003 clients fetches there emails (POP3s) from our dovecot server, they will be asked "......, the CN-Name of this certificate doesn't match with the taken Value. Do you want to continue with this server?. sorry for the poor english translation. Here in german (for some german people): Der Server, mit dem Sie verbunden sind, verwendet ein Sicherheitszertifikat, das nicht verifiziert werden konnte. Der CN-Name des Zertifikates stimmt nicht mit dem übergebenen Wert überein. Möchten Sie diesen Server weiterhin verwenden? many thanks for some hints Richard

[Dovecot] v2.0.2 released
by Timo Sirainen 13 Sep '10

13 Sep '10

http://dovecot.org/releases/2.0/dovecot-2.0.2.tar.gz http://dovecot.org/releases/2.0/dovecot-2.0.2.tar.gz.sig Many small fixes and logging improvements, but most importantly fixes LMTP with Maildir. * vpopmail support is disabled for now, since it's broken. You can use it via checkpassword support or its sql/ldap database directly. - maildir: Fixed "duplicate uidlist entry" errors that happened at least with LMTP when mail was delivered to multiple recipients - Deleting ACLs didn't cause entries to be removed from acl_shared_dict - mail_max_lock_timeout setting wasn't working with all locks - auth_cache_size setting's old-style value wasn't autoconverted and it usually also caused a crash

by Alan Brown 13 Sep '10

This is definitely an operator error issue, but I'm under a bit of pressure. I updated our 1.1.20 installation to 2.0.1 over the weekend and discovered this morning that it's insisting on TLS imap on port 143 as well as port 993 What am I missing? Thanks in advance Alan

[Dovecot] SSHA256 password too short
by Osvaldo Alvarez Pozo 13 Sep '10

13 Sep '10

Hi all I am upgrading a mail system. So I installed aside a new server with debian lenny dovecot 1.2 from backports , postfix 2.5, mysql 5. I recovered the database from the actual production system with a dump. But when i started testing I found this in my logs Sep 13 09:45:07 auth-worker(default): Info: sql(user(a)domain.tld,127.0.0.1): Password mismatch Sep 13 09:45:07 auth-worker(default): Error: ssha256_verify(user(a)domain.tld): SSHA256 password too short Sep 13 09:45:07 auth-worker(default): Warning: Invalid OTP data in passdb Sep 13 09:45:07 auth-worker(default): Warning: Invalid OTP data in passdb But the same users gets connected normally to the production system. I use mysql as driver and my default_schema is md5 Any ideas ?? Thanks in advance

[Dovecot] Proper use of convert plugin?
by Donny Brooks 13 Sep '10

13 Sep '10

I am trying to convert from mbox to maildir on our mail server here at work. The specs are as follows: Fedora 11 x86-64 dovecot-1.2.11-3.fc11.x86_64 postfix-2.5.6-3.fc11.x86_64 dovecot-managesieve-1.2.11-3.fc11.x86_64 We are currently using mbox format with the users INBOX set to /var/spool/mail/username and other mail is in /home/username/Mail. I would like to migrate to maildir format. I tried using the convert plugin as the wiki suggested: mail_location = maildir:~/Maildir protocol imap { mail_plugins = convert } protocol pop3 { mail_plugins = convert } plugin { convert_mail = mbox:/home/%u/Mail:INBOX=/var/spool/mail/%u } When doing this I get this scrolling in the /var/log/maillog... Sep 11 14:41:38 roark dovecot: IMAP(username): Mailbox conversion: Lock creation timeouted Sep 11 14:41:39 roark dovecot: IMAP(username): Fatal: Mailbox conversion failed, exiting Sep 11 14:56:53 roark dovecot: POP3(otheruser): Mailbox conversion: rename(/home/otheruser/Mail, /home/otheruser/Mail-converted) failed: Directory not empty it does this for some users only. Mine for instance never errored and completed perfectly from what I can tell (other than the new mail issue below). The server load has skyrocketed though, so that is most likely part of it. Also, while testing this, new mail was not delivered to the maildir but rather to the old mbox in /var/spool/mail/username. The new mail never showed up until I switched the config back over to the mbox settings. Am I missing something here? Thanks for any insight -- Donny B.
