You could probably achieve this using dnsdb lookups, but my immediate
thought was to do the actual lookup in the RCPT ACL, and carry the
result forward to the routers in a $acl_m variable.
eg
warn set acl_m1=1
dnslists = dsn.rfc-ignorant.org/$domain
But this will only work well for single-recipient messages which
arrive over SMTP, and will break if the recipient address is modified
(or generated) in a prior router.
Over to someone who knows the dnsdb lookup syntax....
