Error: Queue report unavailable – mail system is down

Zimbra reports “ Error: Queue report unavailable – mail system is down ”

We can find that it does not starts correctly the service postfix MTA. But the system shows that everything is working properly:

[zimbra@mail]$ zmcontrol status
Host mail.ttdconline.com
amavis Running
antispam Running
antivirus Running
ldap Running
logger Running
mailbox Running
memcached Running
mta Running
opendkim Running
proxy Running
service webapp Running
snmp Running
spell Running
stats Running
zimbra webapp Running
zimbraAdmin webapp Running
zimlet webapp Running
zmconfigd Running

We reviewed logs and services and we see that the MTA is down:

[zimbra@mail]$ tail -f /var/log/mail.log
