I have set up a form page on a website that emails me through Frontpage
Server Extensions with information. One of the fields is an email address in
a field called "email address". I have successfully added that field the
reply to: in the header so when I receive the email and hit reply it puts in
the address that was added in the form on the website.

However, I have set up a rule that looks for the subject "New Member" and
"replies using a specific template" and I have set up that template which
works fine, but when it automatically replies it sends it to the email that I
have set up on the frontpage server extensions, not the email that was placed
in the header as "reply-to" which it pulled from the form (again, it works
fine if I manually pull up the email and hit reply)

Any suggestions?
