Rulesets

[John Rudd]

For one, I don't think you''ll get any value out of bouncing messages.
Spam just isn't reliably bouncable.  And some spam that is bouncable
ends up bouncing to an address that isn't the actual sender.

But, for what you're trying to do, I'd probably do a delete,forward instead
of bounce,delete.  I'd forward the message to an alias which is a program,
and that program would parse out the message finding out what spam catagories
the message falls into (spam assassin+razor, which rbls, etc), and then takes
action based upon those things in the SpamCheck header.
