I did modify those settings, put AutoWhiteListCount = 5 and AutoWhiteListPercentage = 50.
Something still isn't correct however. for instance I have a greylisting table record that is the result of a test I ran with a script on another server that sent me an email every minute or so..
the result in the greylisting table is 8 "tries" and 597 "count"...
this should be well past the needed amount for an greylisting_autowhitelist table entry but that table is still empty.
