MX Records: Mail Routing Explained

What MX Records Do

MX records are the address plaque of your mail system: DNS entries that tell the world which server receives email for your domain. Without them, senders have nowhere to deliver — mail bounces or vanishes.

Key points:

• An MX record maps yourdomain.com to a mail server hostname, with a priority number.

• Lower priority numbers are tried first; equal numbers load-balance.

• Backup MX servers queue mail when the primary is down.

• Changing providers means repointing MX — the cutover of every email migration.

• MX works with SPF, DKIM and DMARC, which authenticate what that server sends.

The two setups you will actually meet: cPanel hosting mail (mail.yourdomain.com) and Google Workspace (smtp.google.com-class records). Checking takes one command — dig MX yourdomain.com — covered below with the mistakes that break delivery. Records live in the zone editor of your domain registration account or business email hosting setup.
