Nope; that's not true, either.
I was just being facetious. I have been inspired by:

SMTP Server Publishing gives you the SMTP Filter and (with ISA 2000 &
2004), the Message Screecher.]
For this requirement I just need an SMTP NAT and source IP packet filtering
so that I can specify the two Internet subnets that are permitted through.
This is far more capable than the "zealot technique".
It's packet filters that are for the "openaport" fuuls and they only apply
to services operating on the ISA itself.
Is this an SBS deployment?
Not in the Microsoft SBS software sense, but maybe in employee count. There
is a dedicated ISA server and dedicated Exchange server. The change is that
email protection has been outsourced to Postini and I need to deny anonymous
SMTP connections from the rest of the Internet.

Actually Mr. Teacher, can I have that back. I want to say, at the end of
the day, it is the packet filters. :) Server Publishing rules in ISA 2000
are just for all of the "hardware firewall" zealots.
However, in appears as though I can only specify one source subnet per
packet filter.

How is the SMTP service made public; server publishing rules or packet

Been awhile since I used ISA 2000... what is the best way to restrict SMTP
connections from several specific Internet IP subnets?
Thanks.
