I have this set up properly but occasionally when the person receiving the email hits reply, the to box is filled with the from address in the email generated by UE. See attached screen shot from my setup.
So the email is sent by UE and the received email shows from Comfy Campers <firstname.lastname@example.org>.
Then the person hits reply and the reply sometimes goes to the posted "email1" address from the website form, but it sometimes goes to email@example.com (which I don't want)?
What am I doing wrong?
