Error sending emails using smtp GMail

[surtek]

Hi, I use a mantis bt container.
However, I cannot send email using smtp gmail.

This is my email conf.

$g_phpMailer_method = PHPMAILER_METHOD_SMTP;
$g_smtp_host = 'smtp.gmail.com';
$g_smtp_connection_mode = 'tls';
$g_smtp_port = 587;
$g_smtp_username = '[email protected]'; //replace it with your gmail address
$g_smtp_password = '*********'; //replace it with your gmail password
$g_administrator_email = '[email protected]'; //this will be your administrator email address
$g_from_email = '[email protected]';

Please, see attachments wiht mantis bt logs.

Thank you for your attention in advance.
