Replying to my own post yet again. :-)

I think my answer is in how DNS and MX records work. I guess I was 
confused by the term "backup mx." It looks like I would need to setup a 
duplicate mail server on the DSL connection, with a different FQDN, of 
course, and set it up as a final destination for mail. Then in DNS I 
would set up that new server with a lower priority than the normal 
server. If the primary server is down mail should then be delivered to 
the server on the DSL connection and be accessible to the users with a 
simple configuration change. Does this sound correct?
