If you're using Tim's Bogus virus rules for Spamassassin you need to 
zero score the mailScanner ones (from back in the day when mailScanner 
used to 'bounce' spam' and viruses by default)

I see you're using Outlook - could it be the TNEF expander isn't working 

What I do is don't scan via SA for outgoing, only virus scan. I do this 
by the 'from' ip-address range which can't be spoofed quite as easily as 
the email address.
