I've just installed Zimbra on Debian 4.0 and have a problem getting postfix running. I've looked at the various threads and taken care of competing MTAs. Exim 4 was running, but is now deinstalled.
zmcontrol gives me
postfix is not running
saslauthd is running with pid 12551
The zimbra log shows:
Oct 21 13:53:53 localhost postfix/postfix-script: warning: not owned by root: /opt/zimbra/postfix-18.104.22.168/conf/main.cf
Oct 21 13:53:53 localhost postfix/postfix-script: starting the Postfix mail system
Oct 21 13:54:30 localhost postfix/postqueue: fatal: Queue report unavailable - mail system is down
sh -x bin/zmmtactl status indicates that it is indeed postfix that is failing.
If I try connecting to port 25 I get connection refused.
Any thoughts, as far as I can tell /etc/hosts and DNS is configured correctly
