I found a bug in the MIMEdefang code I announced here a few weeks ago - it
was not correctly handling mailman messages containing attachments in
addition to the message body. I have fixed this bug, and a new version of
my code is available at
_footer.pl.txt. The documentation is embedded in that file and can also be
viewed on-line at http://stuff.mit.edu/~jik/software/mailman_mimedefang/.
