But that presumably means you're doing greylisting unconditionally. It
makes a lot more sense only to do it for mail which is actually
considered suspicious for some reason.
Otherwise you just end up delaying a lot of good mail for no reason.
But my impression is that one of the prime reasons for greylisting is to
avoid the high cost of virus and spamscanning. According to my logs,
greylisting stops a huge percentage of spam before the recipient check.
If mail is spam-scanned then greylisted, is it spam-scanned again when
it is resent?
