If you submit to a server-side script such as PHP or ASP.net you may
bypass client-side email software such as OUTLOOK, and respond with a
success/failure message or redirect to a success/failure URL.Your
client's may need to enable a compatible default PDF viewer such as
Adobe Reader in order to submit PDF forms, but, it's possible to respond
with a success/failure with server-side scripts without the need for
OUTLOOK.For online examples:http://www.pdfemail.net/examples/
