Use transport_maps for pop.lightlink.com etc. Postfix will then use relayhost (barracuda) for everything else. /etc/postfix/main.cf: relayhost = barracuda.lightlink.com transport_maps = hash:/etc/postfix/transport /etc/postfix/transport: pop.lightlink.com smtp: Use "postmap /etc/postfix/transport". You can't send *.lightlink.com this way, because that would interfere with local deliveries. Wietse
