Oh, this belongs to -curiosa because 1) RFC 822 actually uses
"headers" as a shorthand for "header fields", 2) the construction
field name + "header" and the phrase "RFC 822 header" referring to a
header field are used in several RFCs (1327, 1505, 2156, 2298, 2919,
3282, 3297, 3458, just to name a few), so it can hardly be considered
ungrammatical as far as the English language is concerned,

Your message contains several other non-standard headers. The Debian
list software adds several more.

The RFC 2369 headers don't work with cross-posting. Mail-Followup-To
