Try setting Emacs's user-mail-address variable, e.g., using 
  M-x customize-variable<RET>user-mail-address<RET>
You won't get the full from address guessing logic used for replies,
but it's not obvious this is appropriate for forwarding.

We should probably use the user's primary address from the notmuch
configuration for this for the sake of consistency, even though
user-mail-address is the more Emacsy thing to use.
