FAQ

Common questions 3 questions

What is an MX record?

An MX (Mail Exchanger) record is a DNS resource record that specifies the mail server responsible for accepting email messages on behalf of a domain name.

Why is the priority number important?

Priority indicates the order in which mail servers should be tried. Lower numbers mean higher priority. If the primary server is down, the sender tries the next server in line.

Can this tool fix email delivery issues?

No, but it can diagnose them. If the tool returns no MX records or incorrect ones, you have a configuration issue preventing email delivery.
