Understanding MX Records
MX (Mail Exchange) records specify the mail servers responsible for receiving email messages for your domain. They include priority values to determine the order in which servers should be tried.
Record Format
<priority> <mail-server>
Priority Values
- Lower numbers = Higher priority
- Multiple servers for redundancy
- Typically 10, 20, 30, etc.
Best Practices
- Always have backup servers
- Use valid hostnames
- Configure SPF records
