SUMMARY In the HTML view of an e-mail message, benign links will trigger scam detection if the displayed URL starts with "http://" but the target URL starts with "https://" (or vice versa). STEPS TO REPRODUCE 1. Send an e-mail to yourself, in rich text mode, containing a link with the text "http://example.com" which leads to "https://example.com". 2. Open the e-mail in HTML view. OBSERVED RESULT A "This message may be a scam" warning appears. EXPECTED RESULT Scam detection should not be triggered on URLs with an HTTP/HTTPS protocol mismatch, as long as the domain and path are the same. It's not a meaningful difference, and displaying the warning in this case may condition users to ignore it when there *is* a misleading link.
