Title: Enhancing Email Security with Exim Configuration Manager and Custom RBLs in cPanel

Introduction:
Email spam is a persistent issue that can lead to security risks and a poor user experience. By configuring Exim and utilizing custom Real-time Blackhole Lists (RBLs), you can significantly improve your email security and reduce spam. In this guide, we will walk you through the process of configuring Exim, setting up Apache SpamAssassin, and adding custom RBLs in cPanel.

Step 1: Access the Exim Configuration Manager in cPanel

1. Log in to your cPanel account.
2. Navigate to the "Email" section.
3. Click on "Exim Configuration Manager."

Step 2: Configure ACL Options

1. Scroll down to the "ACL Options" section.
2. Set "Apache SpamAssassin™️ reject spam score threshold" to 15.
3. Set "Apache SpamAssassin™️: ratelimit spam score threshold" to 15.
4. Enable "Require remote (domain) HELO" by toggling it to "On."

Step 3: Set Up RBLs

1. Scroll down to the "RBLs" section.
2. Enable "RBL: zen.spamhaus.org" by toggling it to "On."
3. Enable "RBL: bl.spamcop.net" by toggling it to "On."

Step 4: Manage Custom RBLs

1. Click on "Manage Custom RBLs."
2. Add a custom RBL for Barracuda:
- Rbl Name: Barracuda
- Rbl Info Url: https://barracudacentral.org/lookups
- Dns List: b.barracudacentral.org
3. Click "Add" to save the custom RBL.
4. Optionally, you can enable the Barracuda RBL later by returning to the "Exim Configuration Manager" and toggling it to "On."

Step 5: Configure Apache SpamAssassin™️

1. Scroll down to the "Apache SpamAssassin™️" section.
2. Enable "Apache SpamAssassin™️: Forced Global" by toggling it to "On."

Step 6: Review and Improve Your Configuration (Optional)

1. cPanel now runs a hashing plugin for SpamAssassin by default, so you will have Razor enabled.
2. If you want to further enhance your email security, you can enable Pyzor and DCC to work alongside Razor. This process is beyond the scope of this guide, but you can find information online by searching for "Configuring Pyzor and DCC with SpamAssassin."

Conclusion:
By configuring Exim, setting up Apache SpamAssassin, and adding custom RBLs in cPanel, you can significantly improve your email security and reduce spam. These steps can provide you with 95-98%+ protection against unwanted emails and enhance your overall email experience.
