Please someone kindly help me. This msg was posted 2 days
ago but the problem still can't be fixed. Please read the
following re-post. Thanks.
My Exchsrv 5.5 was identified as Open Relay server by
several anti-spam services. I tried many ways to fix this
problem by following Paul Robichaux's article
url=/technet/security/mail/excrelay.asp), but all failed
to stop relaying. Even I turned off all relays by
selecting "Do not reroute incoming SMTP mail" on Routing
tab (of course each time I remembered to stop and restart
IMS), the server still keeps relaying endlessly (can be
checked in the Event Viewer/Application Log. I have to

enabled (checked) "Hosts and clients that successfully
authenticate" and "Hosts and clients with these IP
addresses" and added relevant IP addresses in the box.

Thanks for your advice. Done per your instruction. Tested
with telnet commands you suggested and everything looked
OK. However, the server is still busy delivering spam
messages in mass volume. I checked the Event
Viewer/Application Log. After clearing all records, it'll
be full in a few minutes! Huge amount of spam mails are
still passing through!
Now all relay are prohibited. I can't even send out this
message via the server, but the server is still busy to
deliver spam mails from the outside!
Please HELP. THANKS!
