Check MX Records for Email Tool

Mx records - A mail transfer agent or MTA (also called a mail server, or a mail exchange server in the context of the Domain Name System) is a computer program or software agent which transfers electronic mail messages from one computer to another.

An MX record or Mail exchanger record is a type of resource record in the Domain Name System (DNS) specifying how Internet e-mail should be routed. MX records point to the servers to send an e-mail to, and which ones it should be sent to first, by priority.

In order to check the MX record for a domain using Windows, first open a command prompt window (click Start->Run, then type cmd).

A command prompt window will appear, type nslookup and hit enter. Then type "server <DNS>" (such as ns1.serverdomain.com) and hit enter. Then type "set type=mx" without quotes and hit enter. Then type the domain name such as w3courses.com and hit enter. The mx record will then be displayed.
