This is precisely what I do. All handled by an ACL of the form:


  # Reject email for obsolete domains.  It's probably all spam
  # anyway.
  deny    message = The mail domain "$domain" is obsolete.  Instead\n\
                    please try contacting $local_part@$domain_data\n\
                    If you still have problems, try searching for the\n\
                    user at http://www.bath.ac.uk/contact\n\
                    If that doesn't help, please contact postmaster@???
          domains = +obsolete_domains



where the domainlist "+obsolete_domains" is just a simple database
search.
