Hi Thomas,
Firewalls can't prevent relay. You need to configure the Exchange Server
correct to prevent relay from all users (I used to recommend allowing
relay from authenticated users, but criminal spammers are now having
success at taking advantage of that configuration).

I am having Exchange 5.5 behind a firewall. Is there any problem if I do
not close the relay? The configuration of the PIX 515E Firewall is very
well done. Can someone advise.
