Please search within the archives for

Ok, no problem since it is up to you how you expense the software, labor involved.

Better look to Vexira Antivirus (http://www.vexira.com) or RAV then. Both companies offer unlimited domain licensing.

Vexira is the way to go. Updates both the virus scanning engine and virus databases.

This can be done with Postfix, SpamAssassin and Razor. I personally think SpamAssassin + Razor great. Vexira is a enterprise class virus protection program so it is not developed to offer selective domain limitations. I was told by the support guys at Central Command the philosophy is to eliminate the virus problem.
RAV has better per domain/mail box configuration but Vexira overall is a better application and less costly.
