Wait, please read the link I posted.
Scrubbing those headers isn't a bad thing AFAICT, but you really shouldn't be in a position where scrubbing them makes you feel safer - cuz you won't be. That's kinda the point of the arguments against security through obscurity
. That said, I'm not sure how to do that from Thunderbird, or any other mail client. I would actually think this is something you'd wanna do on the mail server itself, but I'm not sure. I'm gonna step aside and let someone more knowledgeable provide you with a definite answer to that. Hang in there.
