Hi All, Please forgive my technical ignorance. I am only able to explain my problem in non-tech language, but hopefully some kind soul can help me? I have an html form on website that when submitted sends 2 emails using PHP mail function. The first is sent to me telling me someone has submitted the form, and for tracking purposes what page it was sent from. The second email is sent to the email address of the submitter. The mailing for both is done from the same PHP script. All works well on my primary domain. I then added two more domains using cpanel, and uploaded the very same form and script to each of them. Now my problem is that when the form is submitted on these new added domains, only the email to me is sent. The email to the submitter is not received. I get no error messages. I made sure the "From" email is a real email on the domain that the form is on. Any help or advice would be warmly welcomed!
