[IMail Forum] Connection refused errors

[David Clausen]

Because of the new virus, I have 2 Mail Exchange Postfix servers sitting in 
front of my v7.15 IMail server collecting about 100k email/day.  The MX 
servers are receiving repeated "Connection refused" errors when trying to 
forward queued email to Imail periodically during the day.  However, I can 
telnet manually to port 25 without any problems just after receiving the 
error.

Aug 22 18:19:28 mx2 postfix/nqmgr[57580]: B5F2911D98: 
to=<[EMAIL PROTECTED]>, relay=none, delay=0, status=deferred (connect to 
mail.domain.com[xx.xxx.xx.xx]: Connection refused)
^Z
Suspended
mx2# telnet mail.domain.com 25
Trying xx.xxx.xx.xx...
Connected to mail.domain.com.
Escape character is '^]'.
220 mail.domain.com (IMail 7.15 230-14) NT-ESMTP Server X1

And then mail will just sit there and queue on the MX servers despite me 
being able to connect via telnet.  I've tried stopping SMTP Service and 
restarting, but no help.  I will also get "server dropped connection without 
sending the initial greeting" errors sporadically.  These machines are 
sitting next to each other in our Rack, and I am aware of no network issues 
between them.

I'm fresh out of ideas.  Thoughts?
