I am running my own server and wish to have a hot backup server. Here is what I plan to do. I'll have two mail servers with identical setup and a SMTP gateway. When mails coming to my SMTP gateway, the Postfix(or any other MTA) will deliver the exact same email to both email servers. Does anyone know how to have Postfix do that?
Could you explain your setup more clearly? An email is a single transaction and so I do not believe a single single can be delivered to two servers. You might want to setup HA on a single IP but still email would be delivered to only one box logically..
