How to Set Up MX Records in cPanel
Configure which mail server handles email for your domain using MX records.
MX (Mail Exchanger) records tell the internet which server handles email for your domain. You typically only need to change these when switching email providers.
Step 1: Open Zone Editor
Log in to cPanel → Domains → Zone Editor. Click Manage next to your domain.
Step 2: Find Existing MX Records
Look for records with Type = MX. These are your current mail routing entries.
Step 3: Add or Edit MX Records
Click Add Record and select MX from the type dropdown.
Fill in:
- Name — your domain (e.g., yourdomain.com.)
- TTL — 14400 (or as instructed by your email provider)
- Priority — lower number = higher priority (10 is common for primary)
- Destination — the mail server hostname provided by your email provider
Common MX Setups
330 Hosting default: Points to our server — no changes needed unless using external email.
Google Workspace: Replace existing MX with Google's values (aspmx.l.google.com, priority 1, etc.)
Microsoft 365: Use the MX value provided in your Microsoft admin portal.
Tips
- MX changes can take 24–48 hours to propagate worldwide
- Always keep a backup of existing records before changing
- Lower priority number = higher preference
