[QUOTE="Wassernelone, post: 14036, member: 4791"]
Soweit bin ich nun

Ich habe eine formular.php angelegt, mit diesem Code hinterlegt

[CODE]<?php

//Import PHPMailer class into the global namespace
use PHPMailer\PHPMailer\PHPMailer;

$msg = '';
//Don't run this unless we're handling a form submission
if (array_key_exists('email', $_POST)) {
    date_default_timezone_set('Etc/UTC');

require '../vendor/autoload.php';

//Create a new PHPMailer instance
    $mail = new PHPMailer();
    //Send using SMTP to localhost (faster and safer than using mail()) – requires a local mail server
    //See other examples for how to use a remote server such as gmail
    $mail->isSMTP();
    $mail->Host = 'localhost';
    $mail->Port = 25;

//Use a fixed address in your own domain as the from address
    //**DO NOT** use the submitter's address here as it will be forgery
    //and will cause your messages to fail SPF checks
    $mail->setFrom('from@example.com', 'First Last');
    //Choose who the message should be sent to
    //You don't have to use a <select> like in this example, you can simply use a fixed address
    //the important thing is *not* to trust an email address submitted from the form directly,
    //as an attacker can substitute their own and try to use your form to send spam
    $addresses = [
        'sales' => 'meinemail@gmx.de',
        'support' => 'meinemail@gmx.de',
        'accounts' => 'meinemail@gmx.de',
    ];
    //Validate address selection before trying to use it
    if (array_key_exists('dept', $_POST) && array_key_exists($_POST['dept'], $addresses)) {
        $mail->addAddress($addresses[$_POST['dept']]);
    } else {
        //Fall back to a fixed address if dept selection is invalid or missing
        $mail->addAddress('meinemail@gmx.de');
    }
    //Put the submitter's address in a reply-to header
    //This will fail if the address provided is invalid,
    //in which case we should ignore the whole request
    if ($mail->addReplyTo($_POST['email'], $_POST['name'])) {
        $mail->Subject = 'PHPMailer contact form';
        //Keep it simple - don't use HTML
        $mail->isHTML(false);
        //Build a simple message body
        $mail->Body = <<<EOT
Email: {$_POST['email']}
Name: {$_POST['name']}
Message: {$_POST['message']}
EOT;
        //Send the message, check for errors
        if (!$mail->send()) {
            //The reason for failing to send will be in $mail->ErrorInfo
            //but it's unsafe to display errors directly to users - process the error, log it on your server.
            $msg = 'Sorry, something went wrong. Please try again later.';
        } else {
            $msg = 'Email versendet.';
        }
    } else {
        $msg = 'Invalid email address, message ignored.';
    }
}
?>[/CODE]

Zusätzlich noch hier verlinkt
<form action="formular.php" class="contact-form" method="post">

Allerdings weiß ich nicht ganz genau wie ich die PHPMailer Funktion installieren kann

Ich hatte jetzt auch Kontakt mit IONOS, ein Formular[B] mit PHP8 ist weiterhin möglich[/B]
