How to block a spammy domain using Spam Filters in DirectAdmin

Blocking spammy domains via Spam Filters in DirectAdmin is an effective way to reduce unwanted emails from specific sources. DirectAdmin, being a popular web hosting control panel, offers various tools to manage email settings, including spam filters. Here’s a comprehensive guide to help you block a spammy domain using Spam Filters in DirectAdmin:

Step 1: Log into DirectAdmin

Start by logging into your DirectAdmin account. Enter your username and password on the login page, which is typically accessed through a URL provided by your hosting provider, such as http://yourdomain.com:2222.

Step 2: Access Email Management

Once logged in, navigate to the “E-mail Management” section on your DirectAdmin dashboard. This section is where you can manage all email-related settings for your domains hosted on the server.

Step 3: Open Spam Filters Settings

Within the “E-mail Management” section, look for an option labeled “Spam Filters,” “SpamAssassin,” or something similar. This varies depending on the DirectAdmin version and configuration set by your hosting provider. Click on this option to access the spam filter settings.

Step 4: Enable SpamAssassin (If Not Already Enabled)

Before you can block specific domains, ensure that SpamAssassin (or the spam filtering tool available) is enabled. If it’s not, there should be an option to enable it within the Spam Filters settings page. Follow the prompts to activate SpamAssassin, which is a powerful, widely-used tool for identifying and filtering spam.

Step 5: Block the Spammy Domain

With SpamAssassin enabled, you can now proceed to block the spammy domain. Look for a section or option labeled “Blacklist,” “Blocklist,” or “Blocked Senders.” Here’s how to proceed:

  • Blacklist/Blocklist Section: Enter the domain you wish to block in the provided field. Typically, you should format it as @spamydomain.com, replacing spammydomain.com with the actual domain name you want to block.
  • Add or Save: After entering the domain, there should be a button to add or save the entry to your blacklist. Click this button to enforce the block.

Step 6: Customize Further Settings (Optional)

Depending on your needs, you might want to customize further settings offered by SpamAssassin or DirectAdmin’s spam filter options. This can include setting a spam score threshold, enabling auto-delete for emails marked as spam, or configuring white lists.

Step 7: Test the Configuration

After setting up the spam filter to block the domain, it’s a good idea to test if the configuration works as expected. You can do this by sending a test email from the blocked domain to your email address hosted on DirectAdmin or asking a colleague to do so.

Tips and Best Practices

  • Regular Updates: Keep your blacklist updated as spammers often change their domains.
  • Avoid Overblocking: Be cautious when blocking entire domains, as this might accidentally block legitimate emails.
  • Review Regularly: Periodically review your spam filter settings and the emails marked as spam to ensure legitimate emails are not being blocked.


Blocking a spammy domain using Spam Filters in DirectAdmin is a straightforward process that significantly enhances your email experience by reducing unwanted emails. By following the steps outlined above, you can effectively manage spam and maintain a cleaner inbox. Always remember to periodically review and adjust your spam filter settings to adapt to evolving spam trends and ensure legitimate emails are not inadvertently blocked.
