'Sieve Email Filtering: Reject and Extended Reject Extensions '
<draft-ietf-sieve-refuse-reject-07.txt> as a Proposed Standard
The draft wants to "update" RFC 3028, but this RFC was obsoleted
by RFC 5228. Good riddance wrt 'reject', reviving this "CANSPAM"
recipe appears to be a bad idea.
LMTP happens after final SMTP delivery. At this point it is not
more possible to cause a "real" SMTP reject while talking with an
alleged sender. That is the main issue in this draft. I'm not
yet convinced that an LMTP "downref" is appropriate or necessary.
