I somehow missed this: http://lartc.org/lartc.html#LARTC.RPDB.MULTIPLE-LINKS - looks like what I'm wanting. But it doesn't mention wether the provders are just routers or NAT-ing routers/firewalls. Will NAT impact? Also just to add to my original mail, the box in question is not a gateway, it doesn't provide connectivity to anyone. It's just a mail server than has to use the extra line to act as a backup MX.
