Re: Recognize mbox files?

       Infact, a solution to the whole problem is simple.  Upon adding
       headers, add the following header to the first message:

       X-RMAIL-MODE: -*- rmail -*-

   I see two problems with this:

   * The first line is supposed to start with `From ' followed by
     name, date, etc.

The header doesn't need to be on the first line though.

   * If you put that header into just the first message, and you
     delete the first message, the header will no longer be present.

Very true, this did not occur to me.  rmail could check, and add the
header when saving the file.  Then it would work for all cases.

       When a buffer was converted to BABYL, the file was never saved
       automatically.

   Rmail still does not save automatically.

That is very good.
