email activation with TANK atuh

[eluser]vicenrele[/eluser]
Hi all!
Can you help me?
I've installed TANK auth library. The user registers is working ok, but the registers with email activation fail. Don't report any error but the mail is not sent. I am working in localhost.

The configuration that I have in "application/config/tank_auth.php" is:

Code:

$config['email_activation'] = TRUE;

And in "application/config/email.php" is:

Code:

$config['mailtype'] = 'html';
$config['charset'] = 'utf-8';
$config['newline'] = "\r\n";
$config['protocol']='smtp';
$config['smtp_host']= "ssl://smtp.gmail.com";
$config['smtp_port']='465';
$config['smtp_timeout']='5';
$config['smtp_user']='[email protected]';
$config['smtp_pass']='password';

Any alternative to TANK auth?
Thanks.

Regards.
