What is the MX record?
Using the MX record, you can enter a domain name by which server handles the mail. The MX record is the abbreviation for Mail eXcahnge.
For a domain name, you can set multiple MX records to increase the probability that the mail will be delivered to ensure redundancy.
Querying MX record
For example, you can use the nslookup command in Windows to access record MX, while under Linux the host command.
Example of a Windows-based nslookup query:
nslookup -q=MX dotroll.com Server: google-public-dns-a.google.com Address: 126.96.36.199 Non-authoritative answer: dotroll.com MX preference = 10, mail exchanger = staffmx.dotroll.com
Example of Linux based host query:
host -t MX dotroll.com dotroll.com mail is handled by 10 staffmx.dotroll.com.
