using multiple email servers

some members of the mom community have expressed an interest in using multiple smtp destinations for failover in case one or the other becomes unavailable. to my surprise, the people complaining have been mail admins! now in order to have failover, you have to have at least two instances of something running. so going on that assumption, you could do either of these bullets...
  • bring up a load-balancer and put your smtp servers behind it. mask the name or IP to something virtual.
  • create multiple entries in dns with the same name. point each record to a different mail server. poor man's load-balancer using round-robin records.
