It has been over six years since the last real discussion took place and almost two decades since the issue was created. Are there any objections from the Thunderbird team or hasn't there just been any volunteer to implement the feature?
I have another use-case for this feature: Many scanners nowadays can send emails with the scan attached. By default, though, these mails have a very generic subject. Being able to change the subject from the mail client conveniently allows finding particular scans later on. I have been doing this in the past using the [Header Tools Lite](https://addons.thunderbird.net/de/thunderbird/addon/header-tools- lite/) addon. This addon, however, is not compatible with newer versions of Thunderbird. After looking through [Thunderbird's WebExtension APIs](https://thunderbird-webextensions.readthedocs.io/en/68/), it seems like editing an email's headers is no longer possible at all. It would be great if we could get at least an API to modify (or create new) mails. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to thunderbird in Ubuntu. https://bugs.launchpad.net/bugs/490935 Title: it is not possible to modify email subject Status in Mozilla Thunderbird: Confirmed Status in thunderbird package in Ubuntu: Triaged Bug description: Binary package hint: thunderbird Microsoft Outlook allows to modify "subject" of incoming emails. This is very very useful, especially when sender used a meaningless subject, or a simple dot. This feature should be very useful also in Thunderbird.
