How to enable Boxtrapper in cPanel?
BoxTrapper in cPanel requires all email senders who are not on your whitelist to reply to a verification email before you receive their mail. This protects your inbox from spam.
If you want to get rid of unwanted emails, then you can enable this on all your emails or only on selected emails, and you need to configure BoxTrapper.
1. Login to your cPanel Account,
2. In the Email section, click on the BoxTrapper Icon.
