How to Manage Email Routing for a Domain in WHM?
Email Routing in WHM determines how your server handles incoming email for each domain. The correct setting ensures mail is delivered to the right mail server — either locally on your server or to an external provider like Google Workspace.
How to Change Email Routing
- Login to WHM.
- Go to DNS Functions → Edit DNS Zone.
- Select the client's domain.
- Check the MX records section.
Alternatively, the client can change it from their own cPanel → Email → MX Entry.
Email Routing Options Explained
| Option | Description | When to Use |
|---|---|---|
| Automatically Detect | cPanel checks MX records and decides routing automatically | Default for most accounts |
| Local Mail Exchanger | All email is delivered locally on this server | When email is hosted on your server |
| Remote Mail Exchanger | Email is routed to an external provider | Client uses Google Workspace, Microsoft 365, Zoho, etc. |
| Backup Mail Exchanger | Server acts as backup if primary MX is unavailable | Advanced setups only |
Setting Up Remote Mail (e.g., Google Workspace)
- Go to the client's cPanel → Email → MX Entry.
- Set Email Routing to Remote Mail Exchanger.
- Delete existing MX records.
- Add Google Workspace MX records:
Priority 1 → ASPMX.L.GOOGLE.COM Priority 5 → ALT1.ASPMX.L.GOOGLE.COM Priority 5 → ALT2.ASPMX.L.GOOGLE.COM Priority 10 → ALT3.ASPMX.L.GOOGLE.COM Priority 10 → ALT4.ASPMX.L.GOOGLE.COM
- Save changes.
Note: When routing email to an external provider, set Email Routing to Remote Mail Exchanger. Without this, your server may try to deliver email locally and fail.
