Sigh, this is getting tiresome.

If you receive a NeXT Mail message and use some other mailer, all you
need to know to extract its contents is that you extract the uuencode
segment with an editor, uncompress, and untar, then use index.rtf to
get you around the other files.

However, this is not enough information for an implementor to write a
program to decode NeXT mail, or one to transmit NeXT mail.

In particular, there are magic cookies in the message header that have
to be set up that are specific to the NeXT.  In particular, there is
the Next-Attachment header line.  What RFC describes this?  There are
also some interesting semantics regarding what characters you are
allowed to put in the subject of your message.

There is, by the way, a good reason why this is not (and should not
be) public information, and why other implementations should not use
the NeXT format, but it can't be discussed here.
