I admit, it has been some time since I used/evaluated clamav, but at 
that time, all it did catch at two small business sites over 3-4 
months was less than one phish per month. And I never saw an actual 
virus mail.

Also, my clamav was pretty much just the default settings.

I suppose you mean that the virus sent mail through an ISP relay, in 
which case of course you are right. I haven't gotten these. Perhaps a 
different type of friends, or just as likely, I have no friends. ;)

Still, URIBL filtering with amavisd-new/SA should catch these, or so 
it would seem.
