I would agree with you that it is a "good thing" (TM) to separate the firewall from the mail server. "Lots of little boxes". The LEAF configuration shouldn't vary very often and a write protected floppy is perfect - extra security! A Mail Server must buffer email and therefore needs a hard disk and a Virus Scanner with regular updates again needs a hard disk. What I have done here, is a LEAF firewall (actually two - one ADSL, one backup ISDN) and a Postfix (http://www.postfix.org/) mail server on an old Pentium 133 with a hard disk "within" the private network. I haven't yet done Anti-virus on the Mail Server (the company already had a company-wide subscription to a client anti-virus product) and I gather that Anti virus *can* cost quite a lot of resources (chiefly CPU cycles, but also disk - zip files etc. must be unpacked before scanning). The one the Postfix people keep seem to be using is AMaViS (http://amavis.org/) and I believe there are *free* anti-virus products with regular updates still available which can be used with amavis under Linux!
