Hi John,
All the step by step details, complete with screen shots for each step,
is in the ISA Server 2000 Exchange 2000/2003 Deployment Kit.
Works great!
Tom

How could the SMTP Message Screener and a SMTP SPAM gateway reside on
ISA together?

Morning John,
Looks like you're enjoying a nice workaholiday too :-)
Happy Thanksgiving!
Tom
ISA/Exchange TIP: if you're cash strapped, put your spam filtering relay
on the ISA firewall itself. The SMTP Message Screener can provide a
front end SMTP solution to offload processing from your back end spam
whacking app to provide "defense in depth" against criminal spammers.

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).
HTH,

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.
