Idea: labelling messages about mu HOT 2 CLOSED

Actually, there is support for the X-Label header (see the mu-find man-page). But mu/mu4e won't modify your messages, probably want to keep it that way. Nothing is stopping you from writing a little script to do so though (e.g. using formail); you could even integrate it with mu4e as an action (see the mu4e documentation).
