I like to personally reply to every registration, which I usually do by replying to the Admin Registration notification email. However, the email address by default ends up being my own email address in the TO: field. Ideally, it should instead be the email address of the Registrant for the registration I just received.
When looking at the actual code in the helper/mail.php file, the logic appears to be there. However, it doesn't work for me. I had to modify the code to make it work.
So I'm curious: is the functionality working for anyone else? When you hit Reply to an Admin Registration email, does the TO populate with your own email address, or the email address of the Registrant?
