Hi All!

I need help - recently started getting these messages in zimbra.log:

Apr 1 11:14:36 pixserver zmmailboxdmgr[22488]: status OK
Apr 1 11:15:00 pixserver postfix/postqueue[22525]: fatal: Queue report unavailable - mail system is down
Apr 1 11:15:30 pixserver postfix/postqueue[22535]: fatal: Queue report unavailable - mail system is down

Apr 1 11:16:03 pixserver zmmailboxdmgr[23028]: status requested
Apr 1 11:16:03 pixserver zmmailboxdmgr[23028]: status OK

However, all services are running:
zimbra@pixserver:~$ zmcontrol status
Host mail.#####.net
antispam Running
antivirus Running
ldap Running
logger Running
mailbox Running
mta Running
snmp Running
spell Running
stats Running

The only clue that I have is that everything was operational until Ubuntu released an openssl (0.9.8g-4ubuntu3.5) update a few days ago. I applied that update, and the server stopped sending mail the next day. I did a reinstall/upgrade, but that did not cure the issue.

Any help would be most appreciated!
