Why use the RPDB if you don't need to?  I subscribe to the KISS notion
(keep it simple, stupid!).

If all of his mail connections are to a single "smarthost", or a small set
of IP addresses, there's no reason for him to use "ip rule", since he can
make a specific route in the main routing table to the destination.

If he is using multiple mailservers in "unknown" networks, then he'll need
to look at the link load sharing solutions, such as multipath routes, or
multiple outbound links with RPDB/fwmark'ing solutions.
