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. -- Can I tell you the truth? I mean this isn't like TV news, is it?
