- jedberg 6y agoTh lock means "this is secure", but we're not talking about that with DKIM/SPF. We're just talking about if the sender can be verified. It doesn't really mean "secure" or not. It just means "we're pretty sure the sender isn't lying". Also, for websites, the website owner loses traffic if they don't offer a secure experience -- they are in complete control of their destiny. For email, the user loses deliverability and may not even be aware of it. Also it's often not within their control to fix. Marking non-signed emails as such would put a huge burden on email users and they might not even be aware of it.
