Troubleshooting Tip: A trusted website is being blocked and categorized as a spam URL by the DNS Filter

[sdebnath]

Description	This article describes how to allow trusted websites that are incorrectly flagged as Spam URLs and denied by the DNS Filter.
Scope	All FortiGate.
Solution	An authentic website is being blocked by the DNS filter, triggering a 'SPAM: URLs' error as shown in the screenshot below. Therefore, to allow access or find a resolution, follow these steps below. From the FortiGate side: Add an Exempt (Whitelist) entry in the DNS Filter Profile. If required, use a wildcard domain (e.g. *.my.mexatlantic.co) to ensure subdomains are also allowed.  Set the action to Exempt for that domain. Verify that the correct policy profile is applied. From the Client side:  Flush the local DNS cache from the user device/PC. After completing the above steps on both the FortiGate and client side, the website will be accessible successfully (see attached screenshot).
