Very recently (shortly after installing latest version of NST) we have this problem:
incoming box is running McAfee Webshield SMTP (listening on port 25). After cleaning virusses, mail goes to NST on the same box (port 2225). After cleaning spam , mail is sent to Exchange 2000 server (on port 25).
This situation was working very well, but now some mail that is sent to us is returned with SMTP error 550 (mailbox unavailable) From Webshield SMTP. Apparantly NST is sometimes not available for receiving mail? Obviously this isn't wanted behaviour.
Maybe it has something to do with concurrent connections from webshield to nst?
Hopefully someone can help me with this problem.
