Hmm. I don't think it does what you expect or both our memories have
gone funny since that request was commissioned. The problem with this
option is that some MTA or MUA will abort a message if any recipient is
rejected, not all continue to deliver with those that were accepted.
I certainly can look into something similar, but the typical behaviour
for B/W listing has been if any recipient is white listed, then its
white listed for all recipients, which typically means skipping the
milter's behaviour. I'll have to refresh my memory as how this option
works in milter-spamc.
In a content filter, one possibility is to record those that B/W list
and after you have a filter result following the final dot, if it would
be rejected as spam, then remove those recipients that are not white
listed from the deliver list. The problem with this method is that the
client MTA gets no feedback as to which recipients were refused, which
would mean the milter has to generate an DSN to the sender.

Yep. Marriage hasn't changed you I see ;-)
