I have a rule in my sendmail.cf to control the number of recipients
tried in each connection, and with this I can control a per IP or
authenticated user maximum number of recipients. This thing can be used
to detect how many recipients was refused, If the counter has X and
milter received Y calls to rcpt the number of refused recipients will be
(X - Y).
