Would people kill me for introducing a `-b' option to mail.local(8) to
stop it from attempting to use the ``biff'' service?
(To Eric: recent FreeBSD kernels can log failed connection attempts to
TCP or UDP ports. So the `biff' attempts clutter the logs. However,
/etc/services is normally being used as a ``list of known services''
as opposed to a ``list of installed services'', so checking with
getservbyname() alone isn't really an option.)
