Three boxes. One Isa2006, IIS and SMTP. How would the idea be if antivirus and antispam protection wanted to be made at isa server level? I mean before reaching to actual Web (IIS) or Mail (SMTP)server?
For Anti Virus Protection, filtering module, filtering the packets at ISA would be ok I guess. But what makes me confusing is for anti spam protection? Will it be same as antivirus filtering? There are some anti spam and anti virus softs for smtp servers. For example http://www.gfi.com/mes/ is for Exchange / SMTP. So how would be the idea if I want to use this one. Will I need to use smart host technology? If yes How?
Or I do not have to worry about antispam as it would be handled like antivirus content filtering by creating policies at isa.
I will soon start publishing the server so any recommendation or suggest will be very important.

An other point I wonder is, Should I use the firewall client for the communation between the servers for more security? For example for dns replication or even also for smtp relay between isa and mail server. And how about DMZ ? Shall I think of it? Or not neseccary? Thank you very much for you time.
