==================================================== 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.
