behavior for mail-to-NetNews gateways should also be specified.
Transparent, "Expires:" can be kept as is (modulo magic SP in news)
my concern here is that (as best I recall) in NetNews, Expires pretty
much means the message will get deleted after that date. I haven't
looked at netnews in years but I seem to recall that expires used to be
used mostly with periodic postings like FAQs that were reissued (and
perhaps revised) on a regular basis.
whereas for email we seem to want something different - a hint to the
recipient about the relevance of the message. which argues for a
different header field name to minimize the potential for confusion.
