No. Then you also silently reject the occasional real email without
notice, and the terrorists have won.
Bouncing it with a 550 at SMTP time as I do thwarts the vast majority of
SPAM without generating an actual bounce message. The only time you'll
get a bounce from trying to send me SPAM is if the server at your end
(or the spammer's end) generates it. The vast majority of SPAM I block
is sent either by botnets or by servers which don't care, so it doesn't
generate bounces, just tells the sending server to wind some barbed
wire around a star-picket and then tin-soldier it.
The SPAM I filter after SMTP time does get dumped, but that's
unquestionably spam. None of the internal filtering will be triggered
by sending-server misconfiguration.
