This really has me stumped and desperate. I upgraded Debian from 5 to 6 (squeeze) and now Dovecot LDA fails. I have checked permissions and the usual. Postfix SMTP, Dovecot POP3 and Dovecot IMAP work. Having to upgrade MySQL from 5.0 to 5.1 made me question that. Logging is of little help. I have turned on logging for LDA to a separate file.

When I try to run the deliver command it returns nothing and appears to do nothing:

~$ cat /etc/hosts | /usr/lib/dovecot/deliver -f root@localhost -d dkoski@[domainhidden].com $

..but then I don't know what to expect.

The log files are owned by dovecot. I tried chmod'ing them to 777 in desperation.

This was working before the upgrade to 1.2.15-4 from 1.0.15-2.3+lenny1.

Postfix reports this stuff:

I tried reinstalling the package dovecot-common. I downloaded it on another machine and compared the md5sum.
