Hmail server with Round cube - SMTP Error (530): Failed to add recipient (SMTP authentication is required.)

I resolve this issue.
In the roundcube config file:

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

file can be found in RoundeCube\Config\ main.inc.php
