IBTD. No documented standard with strange variations in syntax in
practice is worse than a clear standard with MUSTs and MUST NOTs.
then we disagree. IMO, it's nearly always a disservice to the Internet
community for us to define a standard way to do an undesirable thing.
(I say "nearly" because sometimes a feature is undesirable in general
but there are corner cases when it is useful - though I don't think this
is the case for "Expires" if that means that the message store or mail
transport can delete the message without recipients' consent.)
