Maximum Spam Protection through Challenge-Response Verification
BoxTrapper is one of the most effective methods to keep your inbox completely free of unwanted commercial emails. It works on the principle of Challenge-Response Verification: anyone writing to you for the first time must briefly verify themselves as a real person.
1. Enable BoxTrapper
To turn on protection for a specific mailbox, go to BoxTrapper in the Email section of your cPanel:
- Click "Manage" next to the desired account in the list.
- Click the "Enable" button.
Note: All addresses to which you send an email yourself are automatically whitelisted by BoxTrapper.
2. Manage the Most Important Lists
BoxTrapper uses three different lists to sort emails. You can manually adjust these under "Edit White/Black/Ignore Lists":
| Whitelist | Senders on this list are delivered immediately. |
| Ignore List | Emails from these senders are deleted without feedback. |
| Blacklist | Messages are deleted and the sender receives a block notification. |
3. Customize Confirmation Messages
You can change the text that BoxTrapper sends to unknown senders. To do this, click on "Edit Confirmation Messages".
Available Variables (Placeholders):
%email% (Sender), %subject% (Subject), %fromname% (Your Name).Important: Never modify the string verify#%msgid% in the subject line. It is technically required for the verification process.
4. Check the Queue
If you suspect that an important email is "stuck" in verification, click "Review Queue". Here you can manually release messages ("Whitelist and Deliver") or delete them.
Tip from CURIAWEB: BoxTrapper is ideal for addresses suffering from massive spam. For primary business addresses with a lot of new customer contact, we recommend optimizing SpamAssassin instead to avoid creating hurdles for potential clients.
