помогите заменить функцию fsockopen()

Здравствуйте уважаемые! Я начинающий и поэтому много не знаю, например этого. Есть код ниже, он отвечает за отправку уведомлений на email клиентов (например восстановление пароля). Но он не работает из за того что хостер отключил функцию fsockopen(). Хостер сказал что эту функцию можно заменить функцией mail(). Подскажите что нужно изменить в данном коде что бы работала отправка уведомлений. Заранее благодарен.
