Subject: [ietf-dkim] bad mail blowback
So the question is, in my mind, should the receiver just silently
discard
it which breaks reliability but allows the MLM to do nothing special,
or
should the receiver bounce/5xx it back. To my mind, if the MLM is going
to
do something as drastic kick the receiving user, it ought to at least
be
open to a 5xx explanation that it's the mail in question that's the
problem
instead of blindly giving the user X number of 5xx's before they're
declared
a nuisance and kicked.
This is something the lists BCP could discuss. Perhaps something like: bounces
with enhanced status codes of 5.7.1 should not be counted against the recipient
as they are done for message-specific policy reasons and not for something more
general.
(I might have the "5.7.1" wrong, but you get the idea.)
