The current settings, as the name suggests, display the existing spam and virus scanning settings for your domain.

In the “Change Individual Domain Settings” section, you can modify the spam and virus scanning settings for each domain listed under your main hosting account. Let’s take a closer look at these individual settings:

  1. Spam Scanning: This option allows you to enable or disable the spam scanning filter of MailScanner. You can choose between “Yes” or “No” to control whether spam scanning is active.
  2. Virus Scanning: Similarly, you can enable or disable the virus scanning filter for your email using this setting. Choose between “Yes” or “No” to activate or deactivate the virus scanning feature.
  3. Delivered Cleaned Emails: Enabling this setting ensures that emails with detected viruses are delivered after the viruses have been removed. This helps protect your system from potentially harmful email attachments.
  4. Low Scoring Spam: This setting allows a moderate number of emails to pass through while still blocking highly spammy messages. The default spam filter score is set to 6. You can also set up an email address such as to handle filtered spam emails. Note that you must configure this email address for it to work correctly.
  5. High Scoring Spam: This setting determines the initial threshold or spam score for your email. By default, it is set to 10. It instructs MailScanner on how to handle emails that are highly likely to be spam. Similar to low scoring spam, you have options to deliver, delete, forward to, or send them to the SpamBox.

Please note that the options mentioned above are available for customisation to suit your specific requirements and preferences.

In this section, you have the ability to add email addresses to the Spam Whitelist and Spam Blacklist.

By adding email addresses to the Spam Whitelist, you are indicating that emails from those addresses should not be marked as spam and should be delivered to your inbox. This is useful for ensuring that important emails from trusted senders are not mistakenly filtered as spam.

On the other hand, the Spam Blacklist allows you to specify email addresses that should be treated as spam. Any emails originating from addresses in the Spam Blacklist will be flagged as spam and handled according to your configured MailScanner settings.

To add email addresses to either the Spam Whitelist or Spam Blacklist, follow these steps:

  1. Locate the respective section on the screen.
  2. Enter the email address you wish to add.
  3. Click on the appropriate button to add the address to the whitelist or blacklist.

Remember to save your changes after adding or modifying email addresses in the Spam Whitelist or Spam Blacklist. This will ensure that the updated settings are applied to your email filtering system.

You can have up to 30 entries.

As mentioned earlier in the article, the low score and high spam score metrics define the thresholds for classifying emails as spam. In the provided screenshot, the low scoring spam setting is configured at 6, indicating that any emails with a spam score below 6 will be considered legitimate. This value represents the default setting if you have selected or enabled the low spam score option.

The ‘additional email address to list for forwarding spam’ refers to an email address that can be set up to receive forwarded emails identified as spam. This feature allows you to direct spam emails to a specific address for further analysis or review.

We hope that this tutorial has provided you with valuable insights on how to leverage the MailScanner functionality within the cPanel of your account. By configuring and customising these settings, you can enhance your email security and spam protection.
