In the general case, with a milter (or most in-line filtering)
per-user customization (white listing, user Bayes, user rules etc) is
difficult or impossible. As you said, usually there is one SA run per
message, not per recipient.
If the message has only one recipient then per-user rules -may- be
possible. It may also be possible to configure your SMTP system to
take multi-recipient messages and clone them so that there is one
copy per recipient, then the possibility again arises.
Even in that case it may still be difficult, as at the SMTP level
you will see messages before aliases are expanded, forwarding is done
and other possible re-routing, unlike at the delivery state where
every message handled is for an explicit known local recipient.
