If you are delivering to a UUCP domain, you can do DNS on the MX
records.  For example, the machine pandora.uucp.kew.com is MX only.  DNS
is not just address records.  So the MAIL FROM address for a UUCP host
should either have a valid MX record, or be rewritten to by
host!user@relay.fqdn, where of course relay.fqdn has valid address
and/or MX records.
