Are there any specific settings or configurations needed on GMX accounts to properly display HTML emails sent via PHP?

To ensure that HTML emails sent via PHP are properly displayed on GMX accounts, it is important to set the content type header to "text/html" and include the proper headers for MIME encoding. Additionally, make sure that the HTML content is correctly formatted and does not contain any errors that could cause rendering issues. 

<?php
$to = "recipient@example.com";
$subject = "HTML Email Test";
$message = "<html><body><h1>Hello, GMX!</h1><p>This is a test email.</p></body></html>";

$headers = "MIME-Version: 1.0" . "\r\n";
$headers .= "Content-type:text/html;charset=UTF-8" . "\r\n";

mail($to, $subject, $message, $headers);
?>
