You might accept (and onward deliver) unresovlable domains if your
system was using what sendmail calls a "smart host", ie. if you are just
chcuking all mail out to some other (known) host.

The problem is how do you "accept unresolvable domains" when you
don't know that they are unresolvable until you try them? I gess the answer
is you do like sendmail and don't even look them up in the first place.

I have exim machines which use smart hosting by defining a route list
with an entry in the form "* post.thorcom.com bydns_a" which works
well but domain lookups are still performed.

Perhaps what you are looking for is true sendmail-style smart host
operation?
