GMX contact form to report blocked GMX servers

If the sending of emails through the GMX domain fails, then this may be caused by a blacklisting of the recipient system.

In case of a blacklisting, you will always receive a return mail (bouncer) into your inbox. This return mail contains a detailed description of what exactly happened and why your mail could not be delivered.

Please be aware that returned mails due to a full inbox or an erroneous configuration do not belong to the category “blacklisting”.

Through this form you can contact our abuse team to report a blocked GMX server.

  1. A bounce message is an error message sent from an email server to the original sender if the email is not deliverable. This is also referred to as a Delivery Status Notification (DSN).
