8.6.  Duties of a Followup Agent

   A Followup Agent is a special case of a posting agent and as such is
   bound by all the posting agent's requirements plus additional ones.
   Followup agents MUST create valid followups, in particular by
   providing correctly adjusted forms of those headers described as
   inheritable (4.2.2.2), notably the Newgroups header (5.5), the
   Subject header (5.4) and the References header (6.8), and they SHOULD
   observe appropriate quoting conventions in the body (see 4.3.2).

   Followup agents MUST by default follow the Followup-To header when
   deciding which newsgroups a followup is posted to; however posters
   MAY override the default if they wish.

   Followup agents MUST NOT attempt to send email to any address ending
   in ".invalid".  Followup agents SHOULD NOT email copies of the
   followup to the author of the precursor (or any other person) unless
   this has been explicitly requested.
[Mention the Mail-Copies-To header if/when we have that.]
