It's to protect users on systems that might execute it as a program
willy-nilly, e.g. Microsoft.

https://mail.python.org/pipermail/mailman-users/2008-October/063693.html
says how Mailman looks up the MIME part's content-type to see if it's
known.  The email used

    Content-Type: application/x-tar-gz
    Content-Disposition: attachment; filename="distribute.tgz"
    Content-Transfer-Encoding: base64

and application/x-tar-gz isn't in
http://www.iana.org/assignments/media-types/application/  The closest is
http://www.iana.org/assignments/media-types/application/gzip which
leaves the tar for the user to fathom out if left to MIME types alone.

Cheers, Ralph.
