[/B]Today, my server stop sending and recevig e-mails. Everything seems ok with zmcontrol status, but there is no service on port 25. I restarted, rebooted, executed zmfiperms --extended, upgraded from 6.0.10 to 6.0.16, everyting today. My problem is still here.
When I send an e-mail, an essor says me: Try again: Unable to connect to the MTA!
In /var/log/zimbra.log there is only this line about postfix:
-May 23 00:32:08 server sudo: zimbra : TTY=unknown ; PWD=/dati/zimbra ; USER=root ; COMMAND=/opt/zimbra/libexec/zmmtastatus
-May 22 22:32:30 server postfix/postqueue: fatal: Queue report unavailable - mail system is down
You can see that time in postfix line is different from previous line, but i don't know why.
The hosts file seems to be correct, MX point to my server (as until today).
Can anyone help me please??
