I have installed php-cli, composer, phpmailer, ZBateson\MailMimeParser. Yea, i'm trying a lot. If i use script (find in internet)

    <?php
    // See what options are passed in and absorb them:
    $opts=getopt('e:f:t:h');

    // Open the output file
    $fh=fopen('/home/admin/1.txt',"a+");
    
    // Get the message from stdin 
    $fd    = fopen("php://stdin", "r");  
    $lines = array();
    while ($line=fgets($fd)) {
    $lines[]=$line;
    }
    fclose($fd);
    
    // Write it out
    fwrite($fh,"Content:".json_encode($lines)."\n");
    fclose($fh);
    ?>

that doing just fine, and in 1.txt i see message.

But script

#!/usr/bin/php
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;

// Load PHPMailer library
require 'vendor/autoload.php';

// Create PHPMailer object
$mail = new PHPMailer(true);

try {
    // Configure SMTP server settings
    $mail->isSMTP();
    $mail->Host = 'mail.contoso.com';
    $mail->Port = 25;

    // Get message from stdin stream
    $fd = fopen("php://stdin", "r");
    $message = '';
    while ($line = fgets($fd)) {
        $message .= $line;
    }
    fclose($fd);

    // Extract alias from message subject
    $subject = '';
    preg_match('/Subject: (.+)/', $message, $matches);
    if (isset($matches[1])) {
        $subject = $matches[1];
        $alias = 'My Alias'; // Your code to extract alias from message subject
        $mail->Subject = str_replace($subject, $alias, $subject);
    } else {
        throw new Exception('Subject not found in message.');
    }

    // Configure message parameters
    $mail->setFrom('[email protected]', 'Sender Name');
    $mail->addAddress('[email protected]', 'user');
    $mail->Body = $message;

    // Send message
    $mail->send();

    // Write log to /tmp/message.txt file
    $log_message = "Message sent successfully." . PHP_EOL;
    $log_message .= "Subject: " . $mail->Subject . PHP_EOL;
    $log_message .= "From: " . implode(",", $mail->getFromAddresses()) . PHP_EOL;
    $log_message .= "To: " . implode(",", $mail->getToAddresses()) . PHP_EOL;
    file_put_contents('/tmp/message.txt', $log_message, FILE_APPEND | LOCK_EX);
} catch (Exception $e) {
    // Write error to /tmp/message.txt file
    file_put_contents('/tmp/message.txt', 'Error: ' . $e->getMessage() . PHP_EOL, FILE_APPEND | LOCK_EX);
}

Nothing hapens at all. message.txt empty. Yea, this script from Monica. I don't know PHP and how it works.

Postfix log:
