Understanding MX Record Components
Each MX record contains critical information that determines how emails are routed to your domain. Understanding these components is essential for proper email configuration:
| Component | Description | Example | Impact |
|---|---|---|---|
| Priority | Numeric value determining mail server preference | 10 | Lower numbers = higher priority |
| Mail Server | Hostname of the email server | mail.example.com | Destination for incoming emails |
| TTL | Time-to-live for DNS caching | 3600s | Cache duration in DNS servers |
MX Record Configuration Best Practices
Setup Steps

- 2Configure MX Records
Add or modify MX records with appropriate priorities and hostnames
- 3Set Priorities Correctly
Ensure lower numbers for primary servers, higher for backups
- 4Test and Verify
Use our MX checker to confirm changes are properly propagated
Example Configuration
| Priority | Mail Server | Purpose |
|---|---|---|
10 | mail1.example.com | Primary Server |
20 | mail2.example.com | Backup Server |
30 | mail3.example.com | Tertiary Server |
Pro Tip: Always configure at least two MX records for redundancy. The primary server handles most traffic, while backup servers ensure continuity during maintenance or outages.
