Re: incorrect spam setups cause spool messes on forwarders

[Jared Mauch <jared () puck nether net>]

        I think you will find that people who want to reject the spam
but don't want to accidentally reject real mail will sometimes
use 45x instead of 55x error codes.

        I know when i was rejecting spam at the SMTP layer
I first started rejecting with 45x and watched my logs
for those pesky false positives.

        there might be some thought about punish the disk space of
those that are trying to deliver the spam to you ...
