You mean, the mail is delivered from your ISP to you instead of directly? If 
you have a static IP and connected 24/7 to the net I'd change this. Obviously 
you are better off if you can just reject all those viruses instead of taking 
them from your ISP.

You need more than 2 MailScanner processes for this, go to 5 or more. Your 
RAM is enough for that unless something else is hogging memory.
If you can't get mail to you directly the only choice you have is to avoid 
processing as much as possible. F.i. if many viruses go to non-existent 
addresses because of catch-alls remove the catch-alls. Drop sa scanning for 
the time being. And complain to your upstream ISP.
