I think what you want is actually perform with DNS and a redundant server
(ideally on a separate network)

At the top of your DNS records you typically define the MX records and set a
preference for each server, with the server that should handle the mail
receiving the lowest preference (typically 10, in case you ever need to
create a system with a still lower preference) with the backup server a
higher preference (say 40)

If you're to small to have redundant links, you might ask your ISP to handle
this role (be clear that you are just asking for a relay, you don't want
them to hold it)

Best of luck
