Email Routing tells cPanel whether a domain's incoming mail should be handled locally or by another mail server.
- Open cPanel → Email → Email Routing.
- Select the domain.
- Review the current routing choice.
- Use automatic detection unless you have a specific reason to choose a manual route.
- Save the change if you intentionally alter it.
Important: Incorrect routing can make mail appear to disappear or be delivered to the wrong server. If the domain uses an external mail service, its MX records and routing choice must agree with that design.
Changing email routing does not by itself create or correct the required external DNS records.
After an MX or mail-provider change
Automatic detection checks the local DNS zone, not a live lookup of authoritative DNS. It does not continuously update your routing choice. After a migration, compare the public MX records with the intended mail destination and deliberately review Email Routing again. An external DNS change alone does not update the local zone or guarantee the correct routing setting. Test receipt from an unrelated external mailbox after the change.
