In the case of a virus or spam which you have _identified_ as a virus or
spam, you _know_ that the address in the reverse-path is faked. If you
accept that mail and then _later_ generate a bounce, then you are
intentionally sending a 'non-delivery report' to an third party whom you
_know_ to be innocent. You are making yourself part of the problem.

It's an _easy_ balance. You don't generate your own bounces -- you
_reject_ instead of accepting the mail and then bouncing it later. A
legitimate sender will get a bounce, while a drone sending spam will
just move on to the next victim.
