With normal emails this is not a problem. +With emails to a schleuder-list that contain X-RESEND it's different though: it reveals the public key of the actual sender, which probably leaks information about your email address and maybe name to the recipients. + +To prevent that, please de-select `Attach My Public Key` from the `Options`-menu _in each X-RESEND email_. + +As of now there is no option to generally disable attaching your key. [It has already been wished for](https://bugzilla.mozilla.org/show_bug.cgi?id=1654950), though. + |
