sc_mail_send Error using 2 possible authenticators

Hello
I’m trying to send an email using the version 7 and I’m using the sample code ScriptCase, it only change ls data for email addresses and SMTP
and I get the following error

Fatal error: Uncaught exception ‘Swift_TransportException’ with message ‘Failed to authenticate on SMTP server with username “soporte@softgen.co” using 2 possible authenticators’ in C:\Program Files (x86)\scriptcase\v7\wwwroot\scriptcase\prod hird\swift\classes\Swift\Transport\Esmtp\AuthHandler.php:176 Stack trace: #0 C:\Program Files (x86)\scriptcase\v7\wwwroot\scriptcase\prod hird\swift\classes\Swift\Transport\EsmtpTransport.php(307): Swift_Transport_Esmtp_AuthHandler->afterEhlo(Object(Swift_SmtpTransport)) #1 C:\Program Files (x86)\scriptcase\v7\wwwroot\scriptcase\prod hird\swift\classes\Swift\Transport\AbstractSmtpTransport.php(124): Swift_Transport_EsmtpTransport->_doHeloCommand() #2 C:\Program Files (x86)\scriptcase\v7\wwwroot\scriptcase\prod hird\swift\classes\Swift\Mailer.php(79): Swift_Transport_AbstractSmtpTransport->start() #3 C:\Program Files (x86)\scriptcase\v7\wwwroot\scriptcase\app\realkit_completo\control_15\control_15_apl.php(1832): Swift_Mailer->send(Object(Swift_Message), Array) #4 C:\Program Files in C:\Program Files (x86)\scriptcase\v7\wwwroot\scriptcase\prod hird\swift\classes\Swift\Transport\Esmtp\AuthHandler.php on line 176

the code is

$mail_smtp_server = ‘xxx.xxx.com’; // SMTP server name or IP address
$mail_smtp_user = ‘myaccount@mysite.com’; // SMTP user name
$mail_smtp_pass = ‘mypwd’; // SMTP password
$mail_from = ‘myaccount@mysite.com’; // From email
$mail_to = ‘account@domain.com’; // To email
$mail_subject = ‘Mensaje de prueba scriptcase’; // Message subject
$mail_message = ‘Este mensaje lo envia desde realkit.’; // Message body
$mail_format = ‘T’; // Message format: (T)ext or (H)tml

// Send email";
sc_mail_send($mail_smtp_server,
$mail_smtp_user,
$mail_smtp_pass,
$mail_from,
$mail_to,
$mail_subject,
$mail_message,
$mail_format);

Someone could tell me I’m doing wrong?

thank you very much

The errormessages sais: 'Failed to authenticate on SMTP server with username “soporte@softgen.co

.co should be .com I think. I’m using SC7 with custom email and it’s working well here. So I think there must be an error somewhere in your code.
