I am running 5.0.2 on a vm for several years now. We had a power glitch today and now I am unable to connect to smtp, although status says its running. The logs (/var/log/zimbra.log) say otherwise, with the following errors:

file /opt/zimbra/log/zmmailboxd.pid does not exist (shows up later)

May 25 12:52:59 mail zimbramon[20162]: 20162:info: Starting mta
May 25 12:53:00 mail zimbramon[21161]: 21161:info: zmmtaconfig: zmmtaconfig already running at 20598

May 25 12:54:10 mail CRON[21551]: (pam_unix) session closed for user zimbra
May 25 12:54:30 mail postfix/postqueue[21710]: fatal: Queue report unavailable - mail system is dow

Running Postfix check shows the following:
postfix check
postfix/postfix-script: warning: not owned by root: /opt/zimbra/postfix-

Ownership changes to zimbra:zimbra on a restart

Nothing else is running on port 25:
netstat -an | grep 25
tcp6 0 0 :::7025 :::* LISTEN

I have searched a number of similar post, but have not found an answer to by situation.

Can use pastebin if that helps provide necessary info.

Any ideas?
