I have a custom site using PHP mail() as the contact forms delivery system. People are able to contact me using this form and everything has appeared to work for the past year (until now).
Someone tried contacting me with a Safari browser but I recieve nothing in my mailbox. I've tested all browsers work on my Windows computer and they were all able to send forms correctly. I also tested Safari using a live tester here: https://crossbrowsertesting.com/live-testing and it also correctly sent me an email to my inbox.
Still, a person using Safari on their Mac laptop is still unable to send me emails.
I am using a .php file and a .js file for people to send me emails. Everything is very simple and straight forward. Please see here:
Would anyone know what could cause this to not work? I've been banging my head against the keyboard the past several hours trying to troubleshoot this.
