In ssendmail, I use mailertable. If you have multiple internal mailbox
servers for a given recepient domain, you can also setup some
internal-only MX records to use in those mailertable entries, and get some
simple yet fairly robust load-balancing and failover.
We have two MailScanner front-ends for all of our domains (soon to be
four, so I can finally upgrade to a non-ancient MailScanner) and I've been
doing routing this way for years. Very handy, quite flexible.
