It is not really true that doing it at SMTP time only has ill effects
on the SPAMer.  It has similar ill-effects on you because while you
stall his transmission, your mail system is also becoming more
congested with inbound message processing since you must stall from
your end.  If your site is busy, it could become a big deal.

More often than not, the site which is sending you the SPAM is not an
intentionally-willing participant.
