How to whitelist a domain for SpamAssassin

Introduction

The whitelist feature for SpamAssassin only allows email addresses to be whitelisted. However, wildcards can be used in an email address, which allows all email addresses at a domain to be whitelisted with a single entry.

Procedure

1. Login to the cPanel account for which the domain will be whitelisted.
2. Open the "Spam Filters" application in the "Email" section.
3. Click the "Show Additional Configurations" button in the "Additional Configurations (For Advanced Users)" section.
4. Click the "Edit Spam Whitelist Settings" button in the "Whitelist (Emails Always Allowed)" section.
5. Click the '+ Add A New "whitelist_from" Item' button.
6. Enter the wildcard email address for the domain in the empty line.

   *@domain.tld

7. Click the "Update Whitelist (whitelist_from)" button.
