What is an MX record?
An MX record tells the world which mail servers accept inbound email for your domain.
How MX works
When someone sends email to you@yourdomain.com, the sender looks up your domain's MX records. Those records list hostnames of mail servers and a priority value (lower is higher priority).
Best practices
- Use at least two MX records for redundancy when supported.
- Make sure each MX hostname resolves to an A/AAAA record.
- Keep your SPF/DKIM/DMARC records in TXT records, not MX.
