It is not documented, because there is no such variable. It is not
implemented due to overwhelming lack of demand.

Good luck, this will require major surgery. Postfix does not know
any message header information at the time that it formats the
template. At that time it knows only a little about the message
envelope (mainly, the recipient of the bounce message).
