webdevil, thanks for filing this nice idea. It has been on record for a while, and we are looking for volunteers to implement this - can you assist? In the meantime, as a workaround and/or inspiration for coding, you can use Header Tools Lite addon (works with TB24): https://addons.mozilla.org/de/thunderbird/addon/header-tools-lite/
