There you can see no DANE and DNSSEC, could you please add these stuff?
Also I tested the Cipher Suites: https://tls.imirhil.fr/smtp/mail.ecloud.global
Please get rid of the old RSA Ciphers, then you will get a better rank here.
Thanks . Please can you raise a bug on gitlab here as that will help us track this better. Also in case the team wants to get back to you they can do so.
