Doesn't affect my FreeBSD machine :-)

However somebody knew about 'afnog-outgoing at afnog.org'. Nobody really should
be sending directly to this address, since it bypasses all majordomo checks
(such as closed lists being restricted to posting by members).

If you can, it would be a good idea to configure the MTA on the system which
runs majordomo to reject posting to a -outgoing address except by the
majordomo process itself.

I don't know how to do this in Postfix; in exim you'd do something like

majordomo_auth:
   driver = redirect
   local_part_suffix = -outgoing
   condition =  ${if    and{ \
                                {eq {$received_protocol}{local}} \
                                {eq {$sender_ident}{majordomo}} \
                        } \
                {0}{1}}
   data = :fail:You are not authorised to send to this address
   allow_fail

[not tested, but based on an earlier exim-3 expression I had]

Regards,

Brian.
