Matt> Get one input line at a time, and look for Reply-To: and Matt> From: headers to get a reply address. As we are slurping up Matt> lines, watch for '-----BEGIN PGP' lines. If it is for 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. Another idea would be to extract the return address from the PGP userid which signed the script.
