To be clear: This list does not want to make any statement about the quality of the email providers or their services. It takes more than just encryption, to provide a secure and reliable email service.

This is a manually created list which might be outdated in some places. In addition, test results may be wrong for various reasons. Please take into account the fact that email providers have to be very cautious when modifying there servers, e.g. to not lock out old clients and to avoid problems when receiving or sending emails.

So, please don't take this list too seriously, and/or try to ...

... understand the tests results and the implications they might have:

MECSA Technical Details
Understanding the CryptCheck results (IMAPS,POP3S,SMTPS,SMTP and HTTPS)
MTA-STS - RFC 8461 (prevent/detect downgrade attacks and interception by publishing MTA-STS policy via HTTPS) has just been relased (September 2018). It is currently rarely used, partly because it is quite new (first draft 2016) and partly because it has some very unusual aspects, to say the least. Even those who submitted the draft (e.g yahoo, google and microsoft) are not using it.
dismail's outgoing MTA-STS policy implementation is not fully RFC 8461 complient.
STARTTLS Everywhere - prevent/detect downgrade attacks and interception by hosting a preload list.
more to come
