When replying/forwarding etc., you get the 'parent' message plist using
`mu4e-compose-parent-message'. However the message you're about the edit
(in mu4e-compose-mode) is just text, there's no plist to query.
However, `message-mode' has functions such as `message-fetch-field' to
get specific values; message-mode has lots of stuff, it's worth checking
message.el.
Kind regards,
Dirk.
