You could accompish what is essentially source-routing using policy
routing either via subnet or service. General guidelines below:

access-list 1 permit 192.168.1.0 0.0.0.255

route-map production
match 1
set ip next-hop *atmnexthop*

ip policy route-map production

or like:

access-list 101 permit tcp any any eq 25
access-list 101 permit tcp any any eq 110

route-map production
match 101
set ip next-hop *t1nexthop*

ip policy route-map production

I'm really not sure how it will play into a backup senerio. I think that
if there is a valid route for the traffic that the route will be used as
opposed to policy-routing. This would make things harder. Good luck.
