An obvious way to do this would be to extend the "List-" header vocabulary established in RFC 2369 (and registered in http://www.iana.org/assignments/message-headers/message-headers.xhtml#perm-headers), presumably in conjunction with the already defined IMAP URL (see RFCs 5092 and 5593. Should we anticipate an I-D that lays out the details? Of course, am MUA might want to have some mechanism (perhaps a user profile flag) to expose those fields but that is a separate issue and really one of convenience. john p.s. RFC 2369 is in extremely wide use by multiple independent implementations (including the IETF incarnation of MAILMAN). Can anyone think of a reason it should not be a full Standard? Volunteers to do the writeup and herd whatever and whomever need herding?
