Ok, 'refuse' is probably ready for test implementation, IMO.
Thanks to everyone for the feedback.
I would very much like to hear from folks who implement 'refuse'.
A New Internet-Draft is available from the on-line Internet-Drafts directories.
Title : The SIEVE mail filtering language - refuse extension
Author(s) : M. Elvey, A. Melnikov
Filename : draft-elvey-refuse-sieve-01.txt
Pages : 0
Date : 2004-4-5
With 'refuse', Sieve gains the ability to simply not accept an
email during the SMTP transaction (instead of accepting it and then
sending an MDN [MDN] back to the alleged sender using 'reject').
A Joe-job is a spam run forged to appear as though it came from an
innocent party, who is then generally flooded by the bounces, MDNs
and messages with complaints. With 'reject', MDNs [MDN] contribute
to the flood of Joe-job spam to victims of Joe-jobs; SMTP level
refusals usually don't. So 'refuse' provides users the latter
method to handle unwanted email.

If there are no further changes suggested here, we'll let it pickle for a bit
and then pursue further IESG designation (last call for RFC designation?).
(BTW, shouldn't Sieve itself be moving to "Proposed Standard" status?)
