BoxTrapperprotects you from spam by requiring all email senders (the ones that aren't on your Whitelist) to respond to verification emails. This is called challenge-response verification.
It works like this: if you have BoxTrapper enabled, and you receive an email, BoxTrapper automatically sends a verification email to the sender of that email. The sender must complete the verification process before the email can get to your inbox.
So, if you want to get rid of unwanted emails, here's how you can enable Boxtrapper either on all emails or just a few selected emails and configure it.
1. Log in to your cPanel Account.
2. In the Email section, click on BoxTrapper.
3. On the BoxTrapper's page, you will see a list of your emails under the Account heading and the status of BoxTrapper under the Status heading.
Click on Manage.
4. On the BoxTrapper's Manage page, if the status is Disabled, Choose Enable.
And you have enabled BoxTrapper for your email account.
