Login to your DirectAdmin dashboard. Navigate to E-Mail Manager and click the SpamAssassin Setup icon. Ensure the service is Enabled before proceeding.

Match the fields on your screen exactly to the options below. This creates a two-tier defense: filtering suspicious mail and deleting obvious viruses.

After saving, scroll to the bottom and click "EDIT USER PREFERENCES". Paste our custom V5.1 Ultimate Shield Code into the text area and click Save. This version includes the following South African specific protections:

• Logistics Neutralizer: Blocks "Buffalo," "RAM," and "CourierIT" impersonation, even if they pass technical encryption checks.
• NaTIS & PayCity Shield: Identifies fake Enforcement Orders and Traffic Fine scams targeting SA vehicle owners.
• Deep-Scan Engine: Increases scan limits to 5MB, preventing spammers from hiding malware in large high-res attachments.
• cPanel/Voxos Brand Protection: Instantly flags external emails claiming to be "System Administrators" or "Technical Support."

If a legitimate sender (like a bank or known partner) is appearing in your spambox, use the Whitelist box to enter their email address and click Add. Whitelisted senders will always bypass the 4.0 threshold.
