Let me emphasize that the goal---followups to ietf-822(_at_)imc(_dot_)org and
replies to djb(_at_)cr(_dot_)yp(_dot_)to---is _not_ achieved by the old
protocol ``reply
to Reply-To||From; follow up to To+Cc+(Reply-To||From).''
But Reply-To: ietf-822(_at_)imc(_dot_)org / From: djb(_at_)cr(_dot_)yp(_dot_)to
does work for
responses to the list (using Reply-To) or to an individual (using
From). Without changing semantics of any fields. Without adding
new fields. Without expecting UAs to pay attention to an undefined
field. And which works with existing UAs.
No matter what
I put into my message, the old protocol produces a followup address list
that includes the reply address list, so it fails to achieve the goal.
No, see above.
