No, this doesn't bounce the message, it blocks it at SMTP time with
an appropriate error code. That is -exactly- the right thing to do.
It is not trusting any header, or even the envelope contents; just
notifying the agent that is actually attempting to send the message.
(And if that agent is another MTA that didn't recognize the virus
and -does- generate a bounce, that's their problem, not yours.)
