Part of the idea of greylisting is that by the time spam makes it through,
either the spam source will have been added to RBLs, or a similar-enough
message will have hit spamtraps and picked up by some other method (pyzor,
dcc, clamav unoffical sigs, etc), so that by the time it is received, it
will be scored highly enough to be marked as spam.
