Can we set up a reply to email header?

Hi - Is there a way to reply to a form coming in and have that reply routed back to the form submitter? Prior to October 29, 2013 it worked. Now it doesn't. How do I fix that?
Sorry, I don't have a screenshot, this is a request from my sales department. 

Yes, you can set it up like that and further more it is quite easy to do so.

All that you need to do is to enter the email notification or email autoresponder and then set up Reply-To Email field so that it is showing the email field that the person filling out the form is using to add their own email.

You can see more about this here: Notification/Autoresponder Email Details

Do let us know if you have any further questions and we would be happy to answer them for you.
