Problem with sending email on SMTP

Sorry for do not explain the last reply.

This is an example that is working for me on Hostinger:

PHP Code:

$config['protocol'] = 'smtp';
$config['smtp_crypto'] = '';
$config['smtp_host'] = 'mail.mydomain.com';
$config['smtp_port'] = 25;
$config['smtp_user'] = '[email protected]';
$config['smtp_pass'] = 'xxxxxxxx';
$config['mailtype'] = 'html';
$config['smtp_timeout'] = 5;
$config['charset'] = 'utf-8';
$config['wordwrap'] = TRUE;
$config['newline'] = "\r\n";
$config['crlf'] = "\r\n";
