SMTP authentication fails (only with Roundcube)

mysql db has nothing to do with the smtp auth. smtp auth is handled by 
making a connection to the server specified in the config as the smtp 
server. also it uses the settings in the config that specify the 
username and password to be

$rcmail_config['smtp_user'] = '%u';
$rcmail_config['smtp_pass'] = '%p';

so what ever the use enters in as the username and password during the 
login is what is used to auth against the smtp server.
