Well if you do decide to use procmail, you might want to look at this:

I'm particularly fond of this sort of simple filtering

Does Yahoo allow you to upload a virus?  Even if the from address is 
@yahoo.com, I bet it really came from somewhere else.  I think filtering 
on the way out is a good idea.  I really only have experience with 
sendmail though, and I don't think I could get it to filter on relaying.
