This part is not true. You only need to receive the _header_, and can
still return the appropriate rejection code after your check. This
measure uses slightly more bandwidth than per-host blocking, but much
less than accepting and delivering the message.
Furthermore, according to Russ's qmail homepage:
Sam Varshavchik has a patch to qmail-smtpd which calls procmail
recipes to filter spam before it is accepted for delivery.
The above suggestion should be quicker; it performs a very specific
check and can doubtless be implemented faster than the full power of
procmail.
