1 week's spam

It sounds like Julian's experience would indicate that the RBLs in his Spam List never
return a false positive (at least they didn't in the 1 week test).  If that is the case, then
those of us using the same RBLs in SpamAssassin might consider increasing the
scores for these.  After all, using the RBLs in MailScanner's Spam List is roughly
equivalent to using them in SpamAssassin with high scores, so that hitting one RBL
test is sufficient to consider the message as spam.

Of course, those of us using the "high scoring" method to delete spam should be a
little more careful about the score assigned.  Julian's system of delivering everything
is more tolerant of a false positive.
