Yes, interesting. Perhaps using a router such as this would do?

====================================================
dnslookup:
driver = dnslookup
domains = ! +local_domains
transport = remote_smtp
self = fail
no_more
====================================================

Without the 'ignore_target_hosts' option but including 'self = fail' it
detects this particular instance because the lowest MX record points
back to the local host.
