I have an email form on our website that is used to register for an advent. The form is supposed to be sent to me and then a confirmation form is to be sent to the person registering. If I use the website, or an android phone it works perfectly. If the fomr is filled out from an Iphone, the person gets the confirmation but I do not get the registration email. This only happens from an Iphone. Any suggestions how to solve this problem.
