They leak their identity and version number, sometimes even the operating system in <code>User-Agent</code> and <code>X-Mailer</code> headers. They leak the locally set time zone in the <code>Date</code> header. And sometimes they leak the private IP addresses during mail sending.</p> <p>Here I document some settings to hide this information in my preferred mail clients. <strong>Note:</strong> Hiding this metadata might not be enough to fully disguise your choice of mail clients. The ordering of mail headers was not tackled, behavior with attachments varies equally high and other details disclose the mail client identity.</p>
