Introduction
Often, users wish to host their mail on a remote host such as Google's G-Suite, Office 365, or Yahoo Business. These providers can be beneficial for a number of reasons, as they often provide robust spam filtering solutions for incoming email, ensure deliverability of your mail not being marked as spam, and as a failover system for the event your server becomes unstable or crashes, mail will be unaffected. Once configured, you'll create, manage, and view your domain's email within the third party providers portal, independent of your server.
Procedure
- Select a third party mail provider.
- Update your domains MX records (Most typically, the mail host will provide these). This may be done within cPanel's "Edit DNS Zone".
- Update the mail routing for the domain to "Remote Exchanger". This ensures cPanel will appropriately route the domain's email. This is described in more detail here.
- If SPF, DKIM, or DMARC are implemented on your domain, these too will need to be updated to reflect the new host. The majority of mail providers will provide these to you so that they may be updated. This can be accomplished within the "Edit DNS Zone" section of cPanel as with the domains MX records.
