Any "Rmail" specialists out there?

[Dr Rainer Woitok]

Greetings,

long long ago I already used "Rmail" for quite some time,  but also long
long ago I've switched to "View Mail" ("vm"),  because it (then) offered
more features and had a user interface requiring less keystrokes.

Meanwhile however, "vm" is dead,  its last published version 8.2.0b dat-
ing back to 2011-12-27  and meanwhile fails to correctly display certain
Mime mails.  So I'm back to using "Rmail".  My questions:

  * Is there a way to modify the format used to display the lines in the
    "Summary" buffer (apart from suppressing the mail length column)?

    - Less blanks between columns.

    - Date format "YYYY-MM-DD" (or at least "MM-DD").

    - Because I have set "rmail-delete-after-output" to non-nil, and be-
      cause a saved mail is very different from a deleted mail,  I would
      prefer an "S" marker for saved mails over just "D".

  * Is there a way  to specify the order  in which not suppressed header
    lines are displayed?

    - Aparently "Rmail" displays headers  in the same order  as found in
      the original mail,  and whenever I want to inspect some particular
      header, I have to explicitly search for it, because the header or-
      der changes from mail to mail.

Any pointers welcome :-)

Sincerely,
  Rainer

AFAICT, you will need code changes for the above to happen.  For
example, to change the format of summary lines, modify
rmail-header-summary and rmail-create-summary.
