Hello

Can someone tell me if Thunderbird supports RFC 4021 to allow us setting the sensitivity level of a message ?

RFC Link : https://datatracker.ietf.org/doc/html/rfc4021#section-2.1.55 Related Microsoft webpage : https://support.microsoft.com/en-us/office/mark-your-email-as-normal-personal-private-or-confidential-4a76d05b-6c29-4a0d-9096-71784a6b12c1 Other mail clients support it : https://github.com/M66B/FairEmail/blob/master/FAQ.md#user-content-faq177

But it seems TB doesn't support it... and this is usefull in my company (we setup rules based on it, like blocking forwards when "Personal" is set).

Thanks for the information
