mailman breaks PGP/MIME messages

Bug Description

When sending PGP/MIME messages to mailman, mailman
tries to wrap the message by packaging it into its own
message. To quote the enimgamil developers:

"The message from mailman, however, has a Content-
Type: multipart/mixed, where the signed message is
packed into the first part of that message (there is an
additional part with some footer message). This is not
compliant to the PGP/MIME standard, no tool will be able
to read such a message."

I originally filed this bug with the enigmail developers,
but agree with them that the bug is on mailman's side.
Original bug report (including attachments of example
mail) can be read at

This is with the mailman 2.1.2-6 deian package

As I see it, the mp/signed part is neatly packaged as-is into the
mp/mixed part. That's perfectly legal. In fact, KMail detects the
signature perfectly well (except that I don't have the key).

You can safely delete this bugreport.

Anybody in the mailman dev team? This bug has been obsolete for 13 years. Time to close it?
