OpenCart 2.1 Why don't I receive order notifications from guests?

Question

opencart

I made a mailbox to [email protected], redirecting from it to @gmail.com.
The settings are correct, the notification of the order is worth it. but does not come.
Made test.php <?php mail("[email protected]", "Subject", "Message");?> - the letter has arrived;
I tried to recover the admin password - the letter came.
The cart works on the Ajax Quick Checkout 6.3.3 module, I entered my mail in the email field and made it invisible, but mandatory.

Answer 1

as far as I understand, you need to configure smtp to send mail,
first check the possibility of sending mail via smtp something like this blog.sergey-lysenko.ru/2013/05/smtp-and-pop3-monit...
well, you can also turn to google for clarification, but what you are checking is the normal mail() function, it is not related to smtp
