Manage Your Inbox

This section includes features that help you manage your email. 


Use this interface to configure an email account to send automated emails. This can be useful if you're on vacation, unavailable, or have a generic message to send often.

Add an autoresponder


You can only add one autoresponder for each email address. If you attempt to add multiple autoresponders, an error message will appear.

To add an autoresponder, perform the following steps:

  1. Click Add Autoresponder. A new interface will appear.
  2. Select a character set from the Character Set menu. We recommend that you use the default Character Set value of utf-8.
  3. Enter the interval, in hours, to wait between responses to the same email address.
    • For example, you could create an autoresponder with an interval of 24. If it receives an email at 8:00 AM on Monday, it immediately responds to the message. It doesn't respond again to the same email address until 8:00 AM on Tuesday.
    • If you set the interval to 0, the system sends an automatic response to every email.
  4. In the From text box, enter the username to appear in the response.
  5. In the Subject text box, enter the subject to appear in the response.
  6. If the response message includes HTML tags, select the HTML checkbox.
  7. In the Body text box, enter the text of the response, for example:

    I am out of the office until July 2nd. You can reach me on my cell phone in case of emergencies.
    • You can use the following tags in the message. They represent information, such as the incoming email's sender or subject:
      • %subject% — The subject of the message that the autoresponder received.
      • %from% — The name of the sender of the message that the autoresponder received. If the sender's name was not in the original email's header, the %from% tag prints the sender's email address.
      • %email% — The sender's email address.
    • Tags use percentage signs (%) as markers.
  8. Select a start time. You can select Immediately or Custom.
    • If you select Custom, a small calendar will appear. Use the calendar to configure your start time. Click anywhere outside of the calendar to save the configuration and close the calendar. Your chosen date and time will replace the Custom text.

    • The system bases the time on the user's local computer's time setting and translates it into it.
    • This feature uses 12-hour notation and reformats times in 24-hour notation. For example, if you select 18:30 as the start time, the system automatically reformats the time as 6:30 PM.

  9. Select a stop time. You can select Never or Custom.


    You must select a stop time that is later than the start time.

  10. Click Create to create the autoresponder. Click Modify to update the current autoresponder.

External Authentication


You will see this section if your hosting provider enables External Authentication for your account.

Your hosting provider may let you access Webmail with external authentication credentials. For example, you could use cPanelID, WHMCS, Google® Accounts, Facebook®, or your hosting provider's portal. If you do this, you don't have to remember as many passwords.

The External Authentication tab lists the credentials for OpenID Connect-compliant identity providers that you can use to log in to Webmail. You can also use this section of the Password and Security interface to link new credentials or unlink existing credentials.


  • You can only view external authentication methods if they are available.
  • Most identity providers let you register during this process.
  • Your cPanelID uses the same login as the store, the ticket system, and the billing system. If you do not already use a cPanelID, you can register for one during the authentication process.
  • You can link one or more external accounts to one or more Webmail accounts.
  • Some identity providers use two-factor authentication (2FA). You must log in through them and use 2FA.
Link your account

To link your account with a provider:

  1. Select the External Authentication tab.
  2. Click Link Account next to the name of the appropriate identity provider. A new login interface will appear for that identity provider.
  3. Enter the requested login credentials. If you're logged in to that provider, the Password and Security interface skips this step.
  4. Confirm linking your account with the provider.
  5. Confirm that you wish to link your Webmail account to the provider's authentication credentials.

To unlink your account, click Unlink Account for the appropriate account.

A new interface will appear to confirm unlinking your account.

Fight Spam

This section includes features that help you manage and protect your inbox from spam.

  7. Select the Automatically whitelist the To and From lines from whitelisted senders (whitelist by association) checkbox to automatically whitelist addresses in the To and CC lines of incoming whitelisted emails. 

  8. Click Save.

Edit Confirmation Messages

To configure your BoxTrapper messages, perform the following steps:

  1. Click Edit Confirmation Messages. BoxTrapper automatically responds to email with messages that the system builds from the following templates:

    • blacklist — BoxTrapper responds with this message when a blacklisted address sends an email.

    • returnverify — BoxTrapper responds with this message when the verification process fails.

    • verifyreleased — BoxTrapper responds with this message when a person responds to the verify message with an email or a click on the verification link.

    • verify — BoxTrapper responds with this message when an address that does not exist on the whitelist or blacklist sends an email. This message requests a response to confirm that the sender is legitimate.

  2. To customize the verification and blacklist message templates, click Edit. (To restore the default message templates, click Reset to Default.) A new interface will appear. These templates use the following variables:

    • %email% — The sender's email address.

    • %fromname% — The recipient's name.

    • %subject% — The subject of the sender's email.

    • %acct% — The recipient's username.

    • %msgid% — The message ID of the sender's email.

    • %headers% — The heading information of the sender's email.

    • %if can_verify_web% and %endif% — These tags enclose a section that allows BoxTrapper to verify senders through a web link.


      Do not alter verify#%msgid% in the subject line of the verify message template. BoxTrapper requires that specific code to function properly.

Edit Lists

To edit the white, black, or ignore lists, perform the following steps:

  1. Click Edit White/Black/Ignore lists.

  2. Click the list that you want to modify.

  3. Enter any messages, subjects, or email addresses to filter.

Other Webmail Features

The features in this section perform different actions in Webmail.

Configure Mail Client

Use this interface to configure a desktop email client (for example, MacOS®® for Mojave). Email clients require specific information. The options below provide this information. Alternatively you can use the information in the Mail Client Manual Settings section.

Mail Client Automatic Configuration Scripts

This interface has information and tools to help you configure your mail client.

  • To download a tool that automatically configures your mail client, click the desired protocol. Then, follow the displayed directions.
