How to Block Spam Using SpamAssassin in cPanel

How to block spam using SpamAssassin in cPanel. SpamAssassin is an efficient solution for protecting email accounts from unwanted messages.

Through proper configuration of options in cPanel, you can significantly reduce the amount of spam received and improve email communication security.

What is SpamAssassin?

Apache SpamAssassin is an automatic unwanted email (spam) filter integrated into the cPanel control panel.

It analyzes the content of received messages using advanced rules and algorithms to identify and mark suspicious emails as spam.

Advantages of using SpamAssassin

• Reducing the number of spam messages received in the inbox.
• Easy and flexible configuration from the cPanel interface.
• The ability to automatically delete emails marked as spam.
• Whitelist and blacklist functionality for email addresses.

How to block spam using SpamAssassin?

Step 1: Accessing SpamAssassin from cPanel

1. Log into your cPanel account.
2. Go to the Email section and click on Apache SpamAssassin.

Step 2: Activating SpamAssassin

On the SpamAssassin page, click the Enable SpamAssassin button.

After activation, the system will automatically start analyzing received emails.

Step 3: Enabling automatic spam deletion

To automatically delete messages considered spam:

1. Click on Enable Auto-Delete.
2. Set a sensitivity score (default is 5). The lower the score, the stricter the filtering.

We recommend initial testing with auto-delete disabled to avoid losing legitimate emails.

Step 4: Managing whitelist and blacklist

You can manually add email addresses or domains to the whitelist or blacklist:

• Whitelist: messages from these addresses will always be accepted.
• Blacklist: messages will always be treated as spam.

Editing these lists is done in the Configure Apache SpamAssassin section.

Step 5: Adjusting the filtering level

You can modify the default filtering score (e.g., from 5 to 3 or 7).

Lower values will filter more messages but increase the risk of marking legitimate emails as spam.

Step 6: Checking the “Spam” folder

After activation, messages identified as spam are delivered to the “Spam” folder of the email account.

Check this folder periodically to ensure that important messages are not incorrectly filtered.

Recommendations for efficient use of SpamAssassin

• Don’t set a too aggressive score (e.g., below 3) if you receive many legitimate emails.
• Use whitelist for important contacts.
• Enable auto-delete only after a testing period.
• Combine SpamAssassin with other email filters available in cPanel for additional protection.
