Like Matthew, I would like to VERY VERY STRONGLY DISCOURAGE the use of
Sieve scripts to generate MDNs. But I understand the situation Chris
describes, and I agree that we shouldn't pull this out from under
customers that expect it to work this way.
Why are we making a decision in SIEVE WG that MDNs are bad? Surely this is
something that we need to take to the general email community first before
we make such a statement through our actions. Really I dislike the fact
that we are removing a feature from our protocol that serves a valid
purpose just to try and alleviate a problem that frankly won't go away
because a few sieve implementations change. There is much more useful
anti-spam work being done elsewhere that will better address this type of
situation.
What I think we should do is simply recognize that a protocol level reject
is a useful feature missing from SIEVE, and allowing a user or
implementation to control whether they do that or issue an MDN is a good
thing.
Discouraging the use of MDNs as a means of avoiding blow back is really not
our job.
