[Dovecot] Dovecot 2.1.7 not starting properly, mail not delivered

[Aldo & Caroline]

Hi all,

Further digging (and then some more) revealed that dovecot wasn't the
problem (of course). The port numbers (10001, 10002) finally put me on the
right track. It turned out that de SRS daemon (pfix-srsd) had stopped for
some reason. Doing

/etc/init.d/pfix-srsd restart

solved the issue. Now I'm only facing an SASL error, but that's outside the
scope of this mailing list.

Hope I didn't waste too much of anyone's time with this question.

Aldo

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:

# 2.1.7: /etc/dovecot/dovecot.conf
# OS: Linux 3.2.0-4-686-pae i686 Debian 7.1 ext3
auth_mechanisms = plain login
disable_plaintext_auth = no
log_timestamp = "%Y-%m-%d %H:%M:%S "
mail_location = maildir:/var/vmail/%d/%n/Maildir
mail_privileged_group = mail
passdb {
  args = /etc/dovecot/dovecot-sql.conf
  driver = sql
}
protocols = imap pop3
service auth {
  unix_listener auth-master {
    group = vmail
    mode = 0600
    user = vmail
  }
  user = root
}
ssl_cert = </etc/dovecot/dovecot.pem
ssl_key = </etc/dovecot/private/dovecot.pem
userdb {
  args = uid=3000 gid=3000 home=/var/vmail/%d/%n allow_all_users=yes
  driver = static
}
protocol pop3 {
  pop3_uidl_format = %08Xu%08Xv
}
protocol lda {
  auth_socket_path = /var/run/dovecot/auth-master
  log_path =
  mail_plugins = sieve
  postmaster_address = aldo at 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.

Aldo Verlinde
