My host is GoDaddy. I clicked the lightning bolt and bound name to the name field. The "to" address is email@example.com. I left the smtp and port blank, because that is what I did when I used Universal Email to get Ecart to send receipts.
Also, I got it to send email to my address as a test and my Outlook inbox flagged the message as spam and wouldn't let me read it. I can't get UE to send properly to firstname.lastname@example.org however.
