Greg, I have been setting up the very same situation, however my mail server is located behind a firewall which forwards the mail to imailserver. The "backup" server is a linux sendmail box located in front of the firewall because unfortunately my firewall can forward mail to only one server at a time. I have configured the backup as a 20 mx record and set up an additional service or account in the mail clients to retrieve mail from it if the primary is down. This does not work however because even though imailserver is down the proxy server is where mx 10 is pointed at all times and the outside world thinks the proxy server is the mail server so as a result I can never get any mail to the backup unless the firewall is down also. So I am looking for an alternate solution as well.
