What is an MX record?

An MX (Mail Exchange) record is a DNS record that specifies the mail server responsible for accepting email messages on behalf of a domain. It tells other mail servers where to deliver emails for your domain. MX records include a priority value, where lower numbers indicate higher priority mail servers.

Why do I need multiple MX records?

Multiple MX records provide redundancy and load balancing for email delivery. If the primary mail server (lowest priority number) is unavailable, email will be delivered to the backup servers. This ensures email continuity and prevents message loss during server maintenance or outages.

How do MX record priorities work?

MX record priorities use numerical values where lower numbers indicate higher priority. For example, an MX record with priority 10 will be tried before one with priority 20. If multiple records have the same priority, mail servers will randomly select among them for load balancing.

What happens if MX records are misconfigured?

Misconfigured MX records can cause email delivery failures, bounced messages, or emails being delivered to the wrong server. Common issues include pointing to non-existent servers, incorrect priority settings, or missing backup MX records. Always test MX changes before implementing them in production.
