BoxTrapper (Spam Verification) in cPanel

•  Access the BoxTrapper Interface

1. Log in to your cPanel account.

2. In the Email section, click BoxTrapper.

3. You will see a list of email accounts and each account’s BoxTrapper status.
   
   

•  Enable BoxTrapper for an Email Account

1. Next to the email account you wish to protect, click Manage.

2. On the Manage page, click Enable.

   • Note: Enabling BoxTrapper automatically adds any email address you send to into the whitelist.
     
     

• Configure BoxTrapper Settings

On the BoxTrapper Configuration page you can customise key settings:

Configure Settings

• Email addresses for this account – enter a comma-separated list of forwarder addresses that should bypass verification.

• Your Name – the sender name used in verification emails.

• The number of days to keep logs and messages in the queue – set how long unverified messages and logs are stored.

• Minimum SpamAssassin Spam Score required to bypass BoxTrapper – emails with spam score below this value are delivered automatically.

• Automatically whitelist the To/From lines from whitelisted senders (Whitelist by association) – enable to automatically whitelist addresses that appear in To or CC lines of whitelisted emails.

SpamAssassin Spam Score

BoxTrapper integrates with the SpamAssassin system: if an incoming email’s spam score is lower than your configured threshold, BoxTrapper lets it through without requiring sender verification.

•  Edit Templates & Manage Lists

Edit Confirmation Messages

You can customize the messages that BoxTrapper sends when challenge-response is required:

• verify — sent when a non-whitelisted sender sends you an email.

• verifyreleased — sent when verification is completed successfully.

• returnverify — sent when verification fails.

• blacklist — sent when a blacklisted sender attempts to email you.

Templates use variables such as %email%, %fromname%, %subject%, and %msgid%.

Edit Whitelist, Blacklist & Ignore Lists

You can refine filtering by using the lists:

• Whitelist — senders whose messages are delivered automatically.

• Ignore list — messages from these senders are silently deleted.

• Blacklist — senders get a notification that their message was blocked.

Forward List

If you wish, you can set up one or more email addresses to which verified messages are also forwarded.

•  Monitor Logs & Review Queue

• Review Log – shows daily activity for the BoxTrapper-protected account: who sent an email, whether verification was sent/received.

• Review Queue – shows messages waiting for verification. From here you can manually whitelist or delete entries.
