Nope.  Just don't include any information on that link when you publish
your site info.  If no one knows it is available, no one will route
through it.  Most of the sites I help administer have a "private" list
of connections which are for internal use only. We include that list
when we make up our paths files locally, but we don't advertise the
links.

It depends on the mailer you're running.  It can be done with sendmail,
I believe, and with MMDF, but trying to program something like that is
difficult at best.  A much better way would be to simply remove the
site from your L.sys file until such times as you need it (you don't
call that often, do you?).  Anyone attempting to mail through your site
will end up with their mail being bounced, but you can always reinstall
the entry if you want to use the link yourself.
