Forwarding an Extended Header

If you have questions about sending or receiving an email, always send GMX customer support the text of the extended header. You can see the sending history of an email with the help of an "extended header".

1. Click the information symbol in the relevant email. A window with the extended email information will open.
2. Hold down the left mouse button to select the text, and copy the selected text by pressing Ctrl + C.

   
   
   
   

3. Open a new email and paste the copied text into the message body by pressing Ctrl + V.
4. Send the email to the email address specified by the customer support employee.

Analyze the extended header yourself

By opening the extended header, you can find key details to help determine whether an email is fake.

Scammers may send emails that appear to come from GMX Customer Service. If you want to check whether an email is legitimate and was actually sent by GMX, look for the following indicators:

• Received: This is the most important line, as it shows the route the email took from the sender to the recipient. Each server along the way adds its own "Received" line, containing details such as the IP address, timestamp, and hostname. For GMX emails, you should see "gmx.com" and "mout-csbulk.1and1.com".
• Return-Path: This field indicates the email address where bounce messages (delivery failure notifications) are sent. If the email is genuinely from GMX, this field should also contain "gmx.com".
• Message-ID: This is a unique identifier generated by the sending mail server. A legitimate GMX email should include GMX-related details here.

If you determine that the email is fake, move it to the Spam folder. It will not cause any harm there and will be automatically deleted after some time.

Report email as phishing

If you suspect that you have received a phishing or fake email claiming to be from GMX, you can report it using the Phishing Report Contact Form.
