2. Box Trapper protects your inbox from spam by requiring all email senders who aren’t on your whitelist to reply to a verification email before you can receive their mail. To enable and configure it, click BoxTrapper under the email section.

3. Click Manage next to an email address to enable BoxTrapper.

4. Click the Enable button.

5. You receive a confirmation that BoxTrapper is enabled for this address. Click Go Back.

6. After enabling BoxTrapper, you’ll want to configure your settings. Click Configure Settings.

7. You can set various options here, including auto-whitelisting for addresses to which you send an email. Update the settings you wish and click Save.

8. A green confirmation message appears. Click Go Back to BoxTrapper Configuration to go back to the main BoxTrapper screen.

9. Next, click Edit Confirmation Messages.

10. Confirmation messages are responses email senders receive after sending a message to a BoxTrapper-enabled account. You can edit the standard confirmation messages already set up for you. Once complete, go back to the main BoxTrapper screen.

11. Click Edit White/Black/Ignore Lists.

12. You can add addresses to your Whitelist, Blacklist, and Ignore list in order to permit, deny, and ignore messages from specific accounts.

From here, you can go back to the BoxTrapper main screen to alter some of the many other settings. Once you have BoxTrapper configured to your requirements, you’ll notice a reduction in spam.

13. Another option for controlling spam is SpamAssassin. You can use SpamAssassin in conjunction with BoxTrapper for maximum spam control, or you can use each tool individually. To enable SpamAssassin, click Spam Filters from the cPanel home screen.

14. Click the toggle to enable SpamAssassin.

15. A green confirmation appears in the top right-hand corner and the toggle turns on and turns blue.

16. To further configure SpamAssassin, click Show Additional Configurations at the bottom of the Spam Filters page. This option only exists once SpamAssassin is enabled.
