I'd love to know if anyone has seen this or successfully using it. Several hosting providers will build the DNS zone to list 2, 3, or even 4 different mail servers. According to DNS, you can set secondary MX entries so that you have a redundant mail server.
DNS Report:
"WARNING: You only have 1 MX record. If your primary mail server is down or unreachable, there is a chance that mail may have troubles reaching you."
I'm thinking that somehow, you would need to have the mail servers be aware of all the email accounts that it could support. But say you have 4 servers set up for nothing but email (and they can be the 4 MX records for all your hosted domains), how do they become aware when a customer goes to cPanel and adds a new mail account or alias?
I wish I had a good example of where I've seen this. Interland and Verio both do something similar. The mail servers (multiple) are typically different servers than the hosting server.
It would be cool if there was even a "store and forward" option that could be used in case the primary mail server fails.
