On the first line of filter_begin in mimedefang-filter, place this:
	if (stream_by_recipient()) {
		return;
	}
(see man mimedefang-filter for an explanation of stream_by_recipient)

Then, in filter_begin, build your whitelist stuff to check against
@Recipients (actually, you'll only need to check agains $Recipients[0]
since every message will now have only one recipient).
There's some example whitelisting code in /contrib/linuxorg/filter.
I've also seen several examples submitted to this list incase you need
actual whitelist code examples.
