Message Headers
===============

   Message is quite aggressive on the message generation front.  It has
to be - it's a combined news and mail agent.  To be able to send
combined messages, it has to generate all headers itself (instead of
letting the mail/news system do it) to ensure that mail and news copies
of messages look sufficiently similar.

`message-generate-headers-first'
     If non-`nil', generate all required headers before starting to
     compose the message.

     The variables `message-required-mail-headers' and
     `message-required-news-headers' specify which headers are required.

`message-from-style'
     Specifies how `From' headers should look.  There are four valid
     values:

    `nil'
          Just the address - `king@grassland.com'.

    `parens'
          `king@grassland.com (Elvis Parsley)'.

    `angles'
          `Elvis Parsley <king@grassland.com>'.

    `default'
          Look like `angles' if that doesn't require quoting, and
          `parens' if it does.  If even `parens' requires quoting, use
          `angles' anyway.

`message-deletable-headers'
     Headers in this list that were previously generated by Message
     will be deleted before posting.  Let's say you post an article.
     Then you decide to post it again to some other group, you naughty
     boy, so you jump back to the `*post-buf*' buffer, edit the
     `Newsgroups' line, and ship it off again.  By default, this
     variable makes sure that the old generated `Message-ID' is
     deleted, and a new one generated.  If this isn't done, the entire
     empire would probably crumble, anarchy would prevail, and cats
     would start walking on two legs and rule the world.  Allegedly.

`message-default-headers'
     This string is inserted at the end of the headers in all message
     buffers.

`message-subject-re-regexp'
     Responses to messages have subjects that start with `Re: '.  This
     is _not_ an abbreviation of the English word "response", but is
     Latin, and means "in response to".  Some illiterate nincompoops
     have failed to grasp this fact, and have "internationalized" their
     software to use abonimations like `Aw: ' ("antwort") or `Sv: '
     ("svar") instead, which is meaningless and evil.  However, you may
     have to deal with users that use these evil tools, in which case
     you may set this variable to a regexp that matches these prefixes.
     Myself, I just throw away non-compliant mail.

`message-alternative-emails'
     A regexp to match the alternative email addresses.  The first
     matched address (not primary one) is used in the `From' field.
