 	I guess I'm looking for more of a commercial solution.  That is, I
 	don't want to have to perform a lot of administration of adding
 	filters and virus signatures constantly.

 	Maybe I need to look more at a commerical appliance?  Anyone have
 	any recommendations?  I just want a Outbound solution!
