What is MX record?
MX is an integral part of the DNS record where the abbreviation MX stands for Mail eXchange records. It is used in combination with SMTP (Simple Mail Transfer Protocol) to regulate the email protocol on the server and to route emails to the correct mail server.
- mxb-00082601.gslb.pphosted.com [ Priority: 10 ]
- mxa-00082601.gslb.pphosted.com [ Priority: 10 ]
or for example MX Snapchat where we have multiple Mail eXchange records.
- alt1.aspmx.l.google.com [ Priority: 20 ]
- alt2.aspmx.l.google.com [ Priority: 30 ]
- aspmx.l.google.com [ Priority: 10 ]
- aspmx2.googlemail.com [ Priority: 40 ]
- aspmx3.googlemail.com [ Priority: 50 ]
When it comes to multiple MX record present then it is possible to give different roles to them in terms of balanced load or for example so that the back-up mailserver can be determined in case the one with higher mail server with higher priority due to error is not available. Multiple MX records allow for redundancy and load balancing of email traffic across multiple mail servers.
In conlusion, MX records are an essential part of the DNS system that enables email communication on the internet.
How to check MX record?
There are two ways to check MX records:

- Open Command Prompt (press the windows logo on your keyboard, type cmd, then select Command Prompt), then enter in Command Prompt nslookup -type=mx domainname or nslookup -q=mx domainname, for example, nslookup -type=mx google.com or nslookup -q=mx google.com
Our MX Record Lookup check tool sends a request for information about the present mail servers depending on the domain for which you need details, as well as their IP addresses, including information regarding the priority of mail servers.
