The IESG wrote: > '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. Frank _______________________________________________ Ietf@xxxxxxxx https://www.ietf.org/mailman/listinfo/ietf
