I whitelist mailing list mail and off-list responses thereto, when I can identify it. The idea that ``I don't know anyone in country X, so mail from there must be SPAM'' breaks down for mailing lists. I actually think that in general, if a whitelist is required at all, there must be something wrong with the model. That is probably the case, in fact, but the scheme seems to work well in practice. That doesn't mean that people use SpamAssassin are wrong, but they probably have different goals. My criteria are (a) be conservative (no false positives), and (b) try to minimize the time spent dealing with SPAM and related gizmos given the first constraint.
