How to stop unwanted e-mail using Spam Filters

Table of Contents

This article describes how to use the Spam Filters tool in cPanel to reduce the amount of unwanted e-mail (spam) in your e-mail accounts. Spam Filters (powered by Apache SpamAssassin™) is an automated filtering system that uses a variety of techniques to identify and filter spam messages.

Spam Filters

Spam can be a major annoyance, with messages filling up user inboxes. Additionally, spam messages can contain virus attachments or malicious links.

When you enable Spam Filters, powered by Apache SpamAssassin™, it uses scores to rate the likelihood that a message is spam. You can manage messages that Spam Filters marks as spam in a number of ways. For example, you can route messages marked as spam to specific folders, or you can automatically delete them.

Enabling Spam Filters

  1. Login to cPanel
  2. Open the Spam Filters tool:
    • If you are using the Jupiter theme, on the Tools page, in the Email section, click Spam Filters
    • If you are using the Paper Lantern theme, in the EMAIL section of the cPanel home page, click Spam Filters:
  3. On the Spam Filters page, click Process New Emails and Mark them as Spam.
  4. To enable auto-deletion of spam messages, click Automatically Delete New Spam (Auto-Delete).
    • To change the deletion trigger level, click Configure Auto-Delete Settings. In the Auto-Delete Threshold Score text box, type the score number, and then click Update Auto-Delete Score.

Configuring Mail Spam Filters

You can further customize the parameters to control how Spam Filters examines incoming messages. You can also define whitelists (trusted senders) and blacklists (known spammers).

To customize Spam Filters in cPanel, follow these steps

  1. Login to cPanel
  2. Open the Spam Filters tool:
    • If you are using the Jupiter theme, on the Tools page, in the Email section, click Spam Filters:
    • If you are using the Paper Lantern theme, in the EMAIL section of the cPanel home page, click Spam Filters:
  3. On the Spam Filters page, click Show Additional Configurations.
  4. To configure whitelists, click Edit Spam Whitelist Settings:
    • Click Add A New “whitelist_from” item, and then in the whitelist_from text box, you can specify e-mail addresses that are trusted senders.
    • Click Update Whitelist (whitelist_from).
  5. To configure blacklists, click Edit Spam Blacklist Settings:
    • Click Add A New “blacklist_from” item, and then in the blacklist_from text box, you can specify e-mail addresses that are known spammers.

    • In the scores list box, select the test name, and then type the score value.
    • Click Update Scoring Options.

Disabling Spam Filters

You can disable Spam Filters whenever you want. For example, if you are unable to receive a non-spam e-mail message, you can disable Spam Filters and ask the sender to resend the message so it reaches your account.
