You could implement Linux Virtual Server to "load-balance" the SMTP servers.
The LVS cluster should work regardless of the SMTP machine's OS (which
depends on the mechanism you employ in LVS).
I had this working and it works great, but I did not utilize "mon" which you
might want to use if your worried a host may go down.

(We really are now way off-topic on this MailScanner list...)
Perhaps a combination of two things:
1. Round-robin DNS;
2. Something like "heartbeat" from www.linux-ha.org (it does UNIX, not
just Linux), so that your n hosts (UNIX/Linux) can monitor each other
and take over on failure.
Hope that helps.
