MessageThe fun part is that it's "not that simple" (but of course, you knew 
that)...
At the very least, you need:
1. the mail host to be a secureNAT client to the ISA server
2. protocol rules allowing:
    SMTP
    DNS Query
    DNS Zone Transfer (IIS and Exch SMTP servers; may apply to others)
3. access to a DNS server that can resolve Internet-located hosts

  Could someone please briefly explain what i configuration i need to do to 
allow my mail server (on a separate box) to send mail out thru my ISA firewall.

  Is it just a matter of SMTP outbound, or more??
