Best way to virtualize Thunderbird/mail client

And none of that works against emails that are

7-bit ASCII
and
no attachments (including MIME attachments). Block them all.

Which is what my email servers allow.

Demonstrate the confidence in your capabilities by posting your email address and let's put it to an objective test, then.

Certainly a quality hacker would trivially be able to find one of my email addresses - I have hundreds. That should make it even easier.

Uhm guys this has derailed from topic...
What about focusing on the question as a mere thought excercise? I appreciate your willingness to address the issue we are trying to resolve the best and easiest way possible, but I propose forgetting the "why" and focusing on the "how" or "what".
I'm really interested in this approach of containerizing apps as a security measure.

I'd like to isolate my mail client (Thunderbird) from the rest of my system.

I've found this:

https://mailcow.email/

Have to do some tests yet, but leaving alone the server-side apps and only using the client may work as we want.

I don't understand how this would help. This appears to be a system for running your own mail server. What client are you referring to and what makes it secure?
