I just went through this myself. To save on bandwidth and network cards, I
created one box (I used NT, but Linux works great) that acts as a local
router between the two networks. Then I put static routes on each gateway
router pointing to the NT router for the other network.
So, if someone is on the new network and requests mail.nebi.com, it hit's
the new provider's router, redirects to the NT router, then goes to the mail
server. This way, there is no Internet traffic, there's less hops, and I
only have to multihome one server.
HTH,
