On my debian box dovecot does not start properly any more, and mails don't get delivered or sent. I've googled around without finding any useful leads. Hopefully someone is willing to educate me. My guess is it must be a config problem after an upgrade, since I didn't change anything myself directly. Not sure when it started, since I this mail server is not our default machine (yet).
Symptoms
Upon
/etc/init.d/dovecot restart
my command line says
[ ok ] Restarting IMAP/POP3 mail server: dovecot.
But I find in /var/log/mail.log:

I do NOT see a line like ... dovecot: auth-worker(default): pgsql: Connected to 127.0.0.1 (mailserver) as mentioned in this <https://workaround.org/ispmail/squeeze/setting-up-dovecot?page=1> tutorial, which I used to set up the previous Dovecot version (which worked OK).
When starting Dovecot from the command line with
dovecot -F -c /etc/dovecot/dovecot.conf
nothing is printed (as if the process is waiting for more input), while it should at least produce some output, right?
I'm running Debian 7.1 with an ext3 filesystem together with Postfix 2.9.6 on an x86 machine. CPU info:
processor : 0
vendor_id : AuthenticAMD
cpu family : 16
model : 6
model name : AMD Sempron(tm) 140 Processor
cpu MHz : 800.000
cache size : 1024 KB
As far as I can tell, Postfix is running OK.
/etc/dovecot/dovecot.conf says:

}
protocol lda {
auth_socket_path = /var/run/dovecot/auth-master
log_path =

postmaster_address = aldo@alcatoka.nl
As far as I understand, there must be a process (dovecot-auth?) that takes care of translating mail adresses, taking a string at port 10001 and returning the translated string on 10002. This process does not seem to kick off when dovecot restarts.
Please tell me if I'm thinking in the right direction, and - more importantly - what I need to do to get dovecot running. I will be happy to provide more test results if that helps, just tell me what you need.
