Description

The attached email (which I redacted from a real email received from Office365) is detected a HTML.

This is because it contains ARC * headers, but they're not the first one, so the matcher that looks for ARC headers fails, and the matcher for regular 'From' header also fails because the 'From' headers occurs after 1024 characters.
