Depends on whether you think email should actually be a useful form of
communication or not.  If I can't tell an address that has been given
to me is never going to be delivered, it is not very useful.

If you don't care if things are delivered or not, why not save the
trouble and reject everything?   Maybe there's some way to do the
forwarding in real-time and pass back the result.   Might be difficult
in the general case of forwarding to multiple  recipients or where the
destination expands to a list with mixed results, but for one->one it
seems theoretically possible.
