Re: Intent to revive "expires" header from draft-ietf-mailext-new-fields-15

It's not at all clear that the Usenet notion of "expires" is right for email. I'd look at X.400's expiry date as a starting point - at least it was designed with email in mind.


Then grab the equivalent NetNews header field syntax without
changing a single comma in it (for interoperability):


That is an approved RFC waiting for its number.  It is also
the source for the IANA registration of the Expires: header
field for NetNews.  (See section 3.2.5 and chapter 6)
