Can someone please clarify how the priority functions in an MX Record. My understand was that if the lowest priority record failed to deliver, the email was then routed to the next highest priority record. I've since been told that actually the email is sent to both records. Which is correct?<br />
<br />
The configuration in question is:<br />
smtp.mydomain.com. PRIORITY 5 &nbsp;(IP of my local Exchange Server)<br />
mail.mydomain.com. PRIORITY 15 &nbsp;(IP of WebServer with POP box)<br />
<br />
The thinking behind this was if the local exchange was offline then we would get the mail sent to the POP box and would use Exchange to download from the POP on a schedule.<br />

Can someone please clarify?

DNS MX Record Priority

The Domain Name System (DNS) is a hierarchical, globally distributed system responsible for associating the name of a computer, service or other resource into an IP address for connecting to the Internet or a private network. Most prominently, it translates domain names to the numerical IP addresses needed for the purpose of computer services and devices worldwide.

Exchange is the server side of a collaborative application product that is part of the Microsoft Server infrastructure. Exchange's major features include email, calendaring, contacts and tasks, support for mobile and web-based access to information, and support for data storage.
