That’s the reason we have to still use fax machines right?
I know there are ways to do encryption like PGP on your message directly or I think email sent over TLS? But that isn’t the default right and that’s why I can’t send a picture of my license to the insurance company directly over email?
It is. When you send an email a startls session is created between the servers as its a point to point protocol. That session is then used to send the message. You can downgrade to plain text which is where the problem lies.
