Send tank auth activation email stuck on "waiting"

[eluser]ilSignorCarlo[/eluser]
Hi,
I'm trying to use the Tank Auth library. I followed the installation steps and I'm trying to register a new user.

I set the email configuration this way:

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']='30';

$config['smtp_user']='[email protected]';

$config['smtp_pass']='mypassword';

$config['charset']='utf-8';

$config['newline']='\r\n';

when I try to send an email it remains stuck on "waiting for localhost". After about ten minutes or so it appears the confirmation message that it sent the email, but the email doesn't arrive.

Any suggestion?
