 The certificate authorities (CA) mechanism for validating TLS has proven
 to be rotten to the core in several occasions. While browsing the web, not
 relying on it is quite hard as you might be presented a different
 certificate on each webpage that you are visiting. But in the case of
 email, you basically always use the same and only one: the certificate
 from your email provider. So trusting all those CAs by default and
 allowing so many possible man-in-the-middle attacks is not really needed
 for usability.

 TorBirdy could have an option to distrust all CA authorities by default
 and only rely on custom certificates (exceptions).

 Users could, in the worse case, do TOFU authentication (trust on first
 use) and be guided on how to do so. At best their provider can give them
 better ways of authenticating their certificates. Riseup is proposing this
 on their website for example: https://help.riseup.net/en/certificates.
