I think that what you really want to do here is modify org-mime-compose so
that you can use the send-actions argument to message-mail. In
scimax-email.el I use that to be able to turn an org-heading into an email,
send it, and then jump back to the heading to insert some information about
the email into the heading properties after it is sent. A lot of the
information gets passed via global variables. Maybe there is a better way
to do that, I wrote that code a long time ago.

Otherwise, you need to figure out how to use something like a macro that
captures the current-buffer and creates a lambda function with that
information in it, and attaches it to the message-buffer hook somehow. For
example this will display a message-box for me after the message is sent.

(let ((f `(lambda ()
    (message-box "Came from %s" ,(current-buffer)))))
  (message-mail)
  (add-hook 'kill-buffer-hook f nil t))

Some important notes is this hook is added in local mode, so it only
affects that email buffer.
