What happens then if the only MX points to 127.0.0.1? ;-)

Thank you for your first class support ;-), everything works great now using
this:

dnslookup_not_yet_hosted:
  debug_print = "R: dnslookup_not_yet_hosted for $local_part@$domain"
  driver = dnslookup
  domains = ! @mx_any/ignore=<;127.0.0.1;::1
  transport = remote_smtp
  same_domain_copy_routing = yes
  # ignore private rfc1918 and APIPA addresses
  ignore_target_hosts = 0.0.0.0 : 127.0.0.0/8 : 192.168.0.0/16 :\
                        172.16.0.0/12 : 10.0.0.0/8 : 169.254.0.0/16 :\
                        255.255.255.255


The ignore_target_hosts line is from Debian's dnslookup router.
