I suggest ignoring Reply-To: etc and requiring a return address inside the signed region of the mail, otherwise someone could intercept the mail (suppressing the original) and resend it from his account and the results would get sent to the interceptor.
This is a very good suggestion. I'll change emscrypt to use this.
Another idea would be to extract the return address from the PGP userid which signed the script.
I see that Mark M. has already commented on this, but I'll also add that I didn't want to limit the reply to the address attached to the key. For example, I have several accounts spread around, and I might want the replies to go to anyone of them.
