Ongewenste e-mail filteren (Spam) in cPanel

cPanel allows you to filter messages that are marked as spam and automatically redirect them to a separate folder. This approach helps reduce inbox clutter while still allowing you to review messages that may have been flagged incorrectly.

Prerequisites

Before creating spam filtering rules, spam filtering must already be enabled for the account. If spam filtering is not active, related options will not be available when defining filter rules.

These features are available on standard cPanel hosting omgevingen.

Why redirect spam instead of deleting it

Automatically deleting spam messages can result in lost legitimate emails that were incorrectly classified. Redirecting spam into a dedicated folder allows periodic review and recovery of valid messages if needed.

This method is commonly preferred for business mailboxes or accounts that receive important transactional email.

Creating a Spam folder

A folder must exist before messages can be delivered into it.

1. Access the mailbox using webmail or an email client.
2. Create a new folder named Spam.
3. If using a desktop email client, ensure the folder is subscribed and visible.

Creating a spam filter rule in cPanel

After the folder is created, define a filtering rule in cPanel.

1. Log in to cPanel.
2. Open the Tools pagina.
3. In de E -mail sectie, klikken Email Filters.
4. Locate the mailbox and click Manage Filters.
5. Klikken Create a New Filter.
6. Enter a descriptive filter name.
7. Onder Rules, configure the following:
   • Field: Spam Status
   • Operator: begins with
   • Value: Ja
8. Onder Actions, selecteren Deliver to Folder.
9. Klikken Browse and select the Spam map.
10. Klikken Creëren to activate the filter.

Messages marked as spam are now automatically redirected to the Spam folder.

Advanced filtering options

Additional filtering logic can be applied using spam scores.

• Lower spam scores can be redirected for review.
• Higher spam scores can be discarded automatically.

This allows fine grained control over how aggressive spam handling should be.

Improving spam protection

For enhanced filtering accuracy, reputation based detection, and reduced false positives, dedicated filtering solutions such as SpamExperts can be integrated. Accounts with higher mail volume or stricter delivery requirements may also benefit from infrastructure based on cloud-servers.
