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deny message = The mail domain "$domain" is obsolete.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.
