Informing ProtonMail users about potentially unsafe messages
Hi,
I would like to see this feature added to ProtonMail.
When a ProtonMail user sends email to other email service or receives email from other email service, then ProtonMail will indicate / highlight...
a) When a received message was not encrypted (TLS)
b) When composing a message to a recipient whose email service doesn't support TLS encryption, or when the sender’s domain couldn't be authenticated. An indicator before sending a message to a service that doesn't support TLS encryption
This will be useful, as the user can find out if email (sent / received) is encrypted in transit when communicating with other email service.
Of course we all know many email service does not support PGP
This feature was recently introduced in Gmail

This is important for identify servers and corporation hostile to privacy matters and isolate them. I arrive to PM because of that and to promote a higher standard of privacy for all is essential when our data means money for them.

It is already possible to label emails by a sieve filter if an email was not received by TLS.

This should be very useful, because right now the only way to tell that received mail was encrypted in transit using TLS is to view message headers. Indicator icon on the message would be very nice.
