MX Lookup
Which servers receive a domain's email, with SPF and DMARC checked.
The name you type is looked up by our server and sent back to you; it is not stored.
Type a domain such as gmail.com, a full web address, or an IP address for a reverse (PTR) lookup.

How to use MX Lookup
- Type the domainType a domain such as example.com, a web address, or an IP address.
- Choose recordsLeave All common records, or pick one type such as MX or TXT.
- Read the resultsSee every record with its time to live, and the SPF and DMARC checks for mail domains.
The lookup is set to MX records: the servers that receive a domain's email, each with a priority number. Mail goes to the lowest number first and falls back to the others. The SPF and DMARC records are checked at the same time, since a domain that receives mail should have both.
How it works
MX Lookup is a web page. The name you type is looked up by our server and sent back to you; it is not stored. There is no account and no sign-up; to keep it quick for everyone, each connection has an hourly limit, well above normal use.
Reading MX priorities
10 mx1.example.com and 20 mx2.example.com mean mail tries mx1 first and mx2 if it is down. Two servers with the same number share the load.
