For anyone who is struggling with emails locally I highly recommend using https://mailtrap.io this is a great service to catch emails when working locally.
To set it up open classes/phpmailer/mail.php and enter the SMTP details:
Ensure you enter the username and password provided from mailtrap.
public $Host = 'smtp.mailtrap.io'; public $Mailer = 'smtp'; public $SMTPAuth = true; public $Username = ''; public $Password = ''; //public $SMTPSecure = 'tls';
