Sending email using smtp doesn't work

Works fine with:

public $fromEmail = '[email protected]';
public $protocol = 'smtp';
public $SMTPHost = 'smtp.gmail.com';
public $SMTPUser = '[email protected]';
public $SMTPPass = '********';
public $SMTPPort = 587;
public $SMTPCrypto = 'tls';

Thanks, that works. Is was wrong in the setting of port/crypto and host. I will now start to test using Sendgrid or another email service.
