I'll put a buck o' five on NOOP. Change it to 20. Another
quick way to check for other SMTP command filtering is to disable the
filter and see if your mail comes through.

No McAfee installed. I use Symantec for files/folders
and GFI for SMTP AV/AS.
For more clarification - when I say client I mean a
different location with an Exchange server which can NOT send email to
me. I tested by sending emails from another company/exchange server and
attempting to establish a telnet connection via port 25. Some are
successful and some are not. When I view the ISA logs > I see the
connection open, then close without getting the Exchange SMTP header
that I normally get.

A little bit off maybe but do you have mcafee corporate
installed on the client which has problem?

Hope someone can help!
I think this is an ISA 2004 (patched) issue.
From some clients I can send/receive email just fine
(and telnet port 25). But from other clients I can not. I monitored the
ISA logs and observed the connection initiated then being closed.
From Exchange 2003 box I shut of IMF and GFI services -
still not luck receiving email or telnet'ing from a particular client.
Any ideas would be greatly appreciated.
