GMX SMTP settings

Step-by-step setup guide to configure GMX Mail with SMTP.

Want to send and receive your GMX messages from another email client, like Gmail, Thunderbird, Apple Mail, or Outlook? To do so, you’ll need to configure your GMX SMTP settings. Here’s everything you need to know.

What Are the GMX SMTP Settings?

The Simple Mail Transfer Protocol (SMTP) is a well-known email protocol that you can use to send messages over the Internet. Here’s the information you’ll need to configure your GMX SMTP settings:

  • SMTP Server: smtp.gmx.com
  • SMTP Port: 25 (no TLS/SSL required), 465 (with SSL) or 587 (with TLS)
  • Authentication: Yes
  • SMTP Username: Your GMX email address ([email protected])
  • SMTP Password: Your GMX Mail password

Once you’ve configured your SMTP settings, you’ll be able to send emails using the GMX SMTP server. But if you also want to receive messages, you’ll need to set up another email protocol, such as POP3 or IMAP.

What Are the GMX POP Settings?

You can configure POP3, the latest version of the Post Office Protocol, if you plan to use GMX Mail from just one device. Once POP3 has been set up, you can download your messages from the GMX email server to your preferred email client.

  • POP Server: pop.gmx.com
  • POP Port: 995
  • Requires SSL: Yes
  • POP Username: Your GMX email address ([email protected])
  • POP Password: Your GMX Mail password

What Are the GMX IMAP Settings?

If you’re planning to access GMX Mail from multiple devices, you may want to configure IMAP instead. With IMAP, your messages are stored on a mail server, but you can access them as if they were located on your device.

  • IMAP Server: imap.gmx.com
  • IMAP Port: 993
  • Requires SSL: Yes
  • IMAP Username: Your GMX email address ([email protected])
  • IMAP Password: Your GMX Mail password

How to Configure Your GMX SMTP Settings?

Now that you know the incoming and outgoing mail servers for GMX, let’s configure your GMX SMTP settings in your email client. In this example, we’ll be using Gmail, but this also works with Outlook, Thunderbird, and other popular email software.

Step 1: Open your email client.

Step 2: Go to “Settings”.

Step 3: Under “Send email as”, click “Add another email address”.
