[Dovecot] LMTP proxying strategy with multiple recipient delivery
by Luca Palazzo 13 Sep '10

13 Sep '10

Hi Timo and All, how does Dovecot act when an MTA tries to deliver a multiple recipient message to a LMTP proxied system? Does it uses server affinity table for each recipient? I use lmtp_destination_recipient_limit = 1 setting in postfix to avoid multiple recipient delivery. Is it right? I use lmtp_destination_concurrency_limit = 1 too, but i think that it's useless or, maybe, it can make performance worst. Luca

Re: [Dovecot] Upgraded dovecot - now it insists on imap TLS

I had to set the following: protocol imap { disable_plaintext_auth=no } The default has changed from "no" to "yes" between 1.1.20 and 2.0.1, but the conversion routine didn't pick it up (the wiki Documentation suggests the default is still "no". Perhaps this should be updated?) This still requires TLS on port 993, so there's no additional hole opened. Ironically, we published plans some time back to disable local-access plaintext imap logins in October and have been warning users to change their settings but 90% of them hadn't yet done so.

[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

[Dovecot] Upgraded dovecot - now it insists on imap TLS
by Alan Brown 13 Sep '10

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
