[liberationtech] Email provider enabling enforced SMTP/TLS for inbound MX-received emails

[Fabio Pietrosanti (naif) - lists]

Hi all,

does anyone knows of an email provider enabling enforced SMTP/TLS for
inbound MX-received emails?

Assume that i want my provide to refuse email destinated to me, at
inbound Mail Exchanger level, if they are not coming encrypted with
SMTP/TLS, with a decent TLS version and with a decent cipher.

Ideally, i would like an automatic email to be sent back to the sender
of that email, informing his that his email provider/email server is not
secure and must be updated to enable sending email securely.
It would provide increased security against massive surveillance of my
own email and automatic advocacy and advice for email security to sender
writing me from unsecure email.

Any email provider that enable to do so?
