cPanel - Locking Down the Server – MailRoute Help Center

To configure your cPanel host to bypass the internal SpamAssassin filter and to discard, reject, or file email that did not pass through MailRoute, simply follow these steps:

1. Login to your cPanel account.

2. Click "Email" in the left menu to scroll to the Email Features:

3. Click 'Apache SpamAssassin"

4. Click 'Disable SpamAssassin"

5. Click "Go Back":

6. Click "Email" in the left-hand column again to return to the email settings.

7. Click "Global Email Filters":

8. Click "Create Filter":

9. Name the new filter "Bypassed MailRoute", and add two rules -

"Any Header" "does not contain" "X-Virus-Scanned: by MailRoute"

AND

"Any Header" "does not contain" "Resent-To:"

Choose "Deliver to Folder" or "Discard Message" or "Fail with Message" per your preferences:

And then click "Save"

That's it! That will disable the additional SpamAssassin filtering built into cPanel, and remove any email that came directly into your server, bypassing MailRoute
