I'm sure that this topic has come up many times on the list before, and 
I'm sorry for bringing it up again, but the last time I remember seeing 
it discussed here, I thought that the general consensus was that bounce 
was better, for roughly the following reasons:

1.  Most mass-mailing viruses are sent directly by the virus, in which 
case no one will see any bounces generated.
2.  Bounces will be generated anyway, if a mass-mailed virus is sent to 
an invalid email address, so avoiding action_bounce won't stop bounced 
viruses.
3.  If the the virus is, for example, a Word macro virus, it shouldn't 
be silently dropped.
4.  To summarize, in the man page's words, "It's almost never a good 
idea to hide a problem."

Why the change in recommendation?

Again, sorry for rehashing old material.
