I know of no way, but I was looking from the other direction, trying to
satisfy myself that there was indeed no way.

I actually rely upon that feature to protect addresses that I have whitelisted
(such as postmaster@ or abuse@) against attacks from specific bad-boy domains
(e.g., / and / / /

I satisfied myself at the time I started using router entries of the form
" = error" that the spammers wouldn't have an easy time
getting around our protection to attack our abuse desk directly [1].
