In response to an off-list comment, I'm making a small revision of the mail
message header registry draft [1] to mark header fields defined in RFC822
(as well as RFC2822) as standard rather than just "standards-track". This
raised two questions:
1. Are there any other mail header fields that have achieved full standard
status?
2. RFC2822 dropped the "Encrypted" header field which was defined in
RFC822. I take that to mean it is regarded as obsolete; would this be
correct? My current proposed entry for this is:
[[
<http://id.ninebynine.org/wip/2002/IETF/HeaderField#Encrypted>
a hdr:HeaderField ;
hdr:fieldName "Encrypted" ;
hdr:label "Message encryption information" ;
hdr:protocol hdr:Protocol_mail ;
hdr:status "obsolete" ;
hdr:author hdr:Author_IETF ;
hdr:controller hdr:Author_IETF ;
hdr:specification hdr:RFC822 ;
hdr:comment
"""Defined by RFC 822, but removed in RFC 2822.
Current practice is to use separate encryption, such
as S/MIME or OpenPGP, possibly in conjunction with
RFC 1847 MIME security multiparts.
""" .
