Re: [mailop] Multiple mail server setup

That's a different category of problem. :) Obviously when you get large enough you want to have more than one critical facility. But the idea of a "main" data center and a "backup" data center is very 20th Century. Hot/hot with well-tested failover procedures is the way to go. Doug On 3/1/1

Hi, I’m planning to move my mail setup from one primary and one backup MX to two MXes with equal priority, and one backup MX. To achieve that, I have of course two options available for setting up my MX records: (1) example.com. MX 23 primary.example.com. example.com. MX
