It is simple...
Spamassassin get some score.
to the Tag percent (from score 20) it is HAM.
From Tag to Kill percent it is SPAM, but delivered to the Junk
Over Kill percent (75% from score 20) is not delivered.
And my question is, what is done with email which has score higher then Kill percent?
Is purged or sender got error message?
Is possible to store these emails over Kill percent in the some special account...?
