Take a look to EditEmailSubject MX: it enables the user to edit the mail subject. Optionally the addon copies the original mail to a special folder.
But anyway, email has very little evidence, since it is very easy to tamper the text in th’s files.
It would be nice, if Textmarker would also be able to mark received messages.

This would mean that the original message is changed, which would render the email inadmissible as evidence – it could even be considered falsification.
