While Internet messages should indeed either be sent 7-bit or in
8BITMIME format, the clean thing to do for all those broken and borked
MTAs out there is to either

- handle this on your MTA by enforcing strict 7-bit headers
- have Mailman drop the high order bit to zero (in the headers or the
  body) if MIME content is incorrectly encoded or not compliant for
  whatever reason

The first option should be easy. The second requires a patch...
