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.
