This method can work, but for me anymore the zone between accept mail that might be \
spam and reject during MSTP has narrowed considerably over the years (anything over \
5.0 in SA gets tagged as spam and anything over 7.0 gets rejected outright), so this \
is not that useful anymore.

And, somehow banks seemed to frequently send messages that appeared spammy (much less \
of a problem now), to was not rare to see a bank mail hitting a score that was high \
enough to kick in the greylist and then the banks would never retry.
