There's a way to prevent relaying on Exchange 5.5 and it's posted on MS
Technet. The link is
http://www.microsoft.com/TechNet/exchange/relay.asp and it has nothing
to do with the Pix. If you're allowing traffic from the Internet to
your Exchg server, then you should only permit access to the ports
required for mail traffic. I think the "fixup protocol smtp" could help
in preventing certain attacks by only allowing specific commands to be
sent to your mail server but you still need to limit access to the
server.
