Hello there,

I am having this problem with my Zimbra installation: postfix is not running.
When I do a portscan on the host, it does not list port 25 (pop3 and imap are listed, though).
If I try telnet <host> 110, it says:

+OK <hostname> Zimbra POP3 server ready

If I try it on port 25, however, it doesn't say anything, just the black screen and when I press something and hit Enter, it goes out of telnet command (no error messages).

Some other information:

$ tail -100 /var/log/zimbra.log

If I send an email (from the webmail) to someone in the domain (ie from david@mydomain.com to david@mydomain.com), it works. If I try, however, to send, say someone@hotmail.com, it replies:

An unknown error (mail.TRY_AGAIN) has occurred.
method: [unknown]
msg: try again: Unable to connect to the MTA
code: mail.TRY_AGAIN
detail: soap:Receiver
trace: qtp1176245664-

Looks like the postfix is not running. If I do $ postfix start, it doesn't return any error, but if I check zimbra.log, the results are the same as described above.

Any thoughts?

Thanks in advance,

David
