I was using the "via PHP mail function" when I had my store on a test domain and it was working perfectly. Since moving to the live domain, I have noticed that no emails are sent and no emails are received through the 'contact us' form. It is the exact same store (v4.6.2). I have tried using the SMTP function but I get this message:
Error Message could not be sent.
Mailer Error: SMTP connect() failed. https://github.com/PHPMailer/PHPMailer/wiki/Troubleshooting
If I use PHP, it says the email was successfully sent but it never is received, can anyone advise, please?
