475339 - Ability to change Subject of emails

Status: VERIFIED DUPLICATE of bug 91106

(Thunderbird :: General, enhancement)

Description

[Ben Bucksch (:BenB)]

Request:
I would like to be able to manually change Subject, and maybe From, of emails in my message store (local and IMAP), in case they are overly generic, wrong or otherwise not useful.

Use cases:
- When a longer mail thread changes to an entirely different subject.
- When a private sender uses just "Hi" as Subject, which is a common
  disease by people who are not very familiar with the Internet and mail.
- Unified messaging service (sending fax or voicemail by email)

I have an unified messaging service, from which I get faxes and voicemail.
The subject contains the name of the UMS service and the phone number of the sender/caller.

However, that's only moderately useful, because:
- I don't know all the numbers -> name mapping by heart.
- Even the sender name doesn't tell me the subject (From vs. Subject)
- If I have somebody sending me my postal letters by fax, the Sender is
  entirely useless.

Consequently, I have a lot of mails, all with the same From and Subject, and the only way to tell what they are about is to sort them in very specific folders or/and to open them, each of them. Repeatedly, every time I am looking for a specific letter. Of course, that's not practical.

Therefore, I would like to have an ability to manually change the Subject and maybe From, when I receive the mail, so that I have a meaningful subject and reminder what this is about and can find it again.

I realize that implementation may be hard, because emails are usually not modified by the recipient, and therefore our design, and the design of IMAP, is not made for that. Compare feature: deletion of attachments, bug 2920.

This is a duplicate of bug 91106, and a subset of bug 203913.
