I like that idea. Although it at first sounds like you could implement this in
/etc/mail/access, this is considerably more flexible.

By having it in milter-greylist, you can take advantage of ACL order to
whitelist and/or greylist some addresses first, then blacklist others.

You can also take advantage of the flexible syntax (regular expressions, etc.)
