Php 配置用于在plesk中发送电子邮件的codeigniter（并行）

如何在plesk主机中使用codeigniter发送电子邮件。我把行李放进去了 config文件夹下的email.php文件：

    <?php 
    $config['protocol'] = 'smtp';
    $config['smtp_host'] = 'my-domain.com';
    $config['smtp_user'] = 'info@my-domain.com';
    $config['smtp_pass'] = 'my-email-password';
    $config['smtp_port'] = 587;
    $config['mailtype'] = 'html';
    $config['charset'] = 'utf-8';
    $config['priority'] =5;
    $config['wordwrap'] = TRUE;
