MX Lookup

About MX lookup

What is an MX lookup?

An MX lookup is the retrieval of MX records behind a domain name. MX records are used to specify a domain name's incoming mail servers. This way other mail servers know where to deliver the mail to for that domain name.

This tool can be useful to confirm whether a DNS change has been made correctly, or if you want to know which mail servers are used for a domain name.
