Sorry to spout on about the new version of MailScanner again, rather than
the version you've got, but this should be simple. You will be able to
specify a set of rules for calculating the value "Is It Definitely Spam"
(addresses contained in the ruleset build up your blacklist), and a set for
calculating the value "Is It Definitely Not Spam" (addresses contained in
the ruleset build up your whitelist).

Currently there is a "spam.whitelist.conf" in which you can place all your
whitelist addresses. There is currently no blacklist, but you can easily do
that in sendmail anyway.
