我们的服务器当前正在自动将返回路径设置为{[email protected]}。在用PHP发送电子邮件时，我可以通过执行以下操作来覆盖此内容：

$return = \'<[email protected]>\';
$additional = "-f$return";
mail($to,$subject,$message,$headers, $additional);

我的问题是WordPress没有像本机PHP邮件函数那样提供添加额外\\u参数的功能。是否有一个解决方法可以让这项工作正常进行？以下是我的WordPress插件用于发送电子邮件的实际代码：

$headers = array(
    \'From: Eden Mobility <[email protected]>\',
    \'Content-Type: text/html; charset=UTF-8\',
    \'Return-Path: <[email protected]>\'
);
wp_mail( "[email protected]", \'Your \' . $item . \' renewal is almost due\', $template, $headers ); // LIVE

我注意到的一件事是，我现在在提交邮件时收到警告：

PHP Warning: escapeshellcmd() has been disabled for security reasons in /home/user/domain.co.uk/wp-includes/class-phpmailer.php on line 1442 [02-Feb-2018 15:25:54 UTC]

if ( ! function_exists( \'wp_mail_returnpath_phpmailer_init\' ) ) {
    function wp_mail_returnpath_phpmailer_init( $phpmailer ) {
        // Set the Sender (return-path) if it is not already set
        if ( filter_var( $params->Sender, FILTER_VALIDATE_EMAIL ) !== true ) {
            $phpmailer->Sender = $phpmailer->From;
        }
    }
}

add_action(\'phpmailer_init\',\'wp_mail_returnpath_phpmailer_init\');
