How can I have the sender email address to use the email field?

I need to be able to send email to our ticketing system with the senders email address being the "senders email address" field. I followed instructions to to create a Mandrill account, done that. Tested the email submissions, but I cannot find in where I change in the email notifications to have the senders address be the "Email Address" field. When I add SMTP, Mandrill account info, the key, nothing shows up for me to change senders email address. This is very very very important, otherwise I'd have to find another form builder and I dont want to do that. PLEASE HELP!

This is a duplicate thread. I already posted a reply on the original thread. Here's the link: https://www.jotform.com/answers/1216354.
