In order to send mail through GMX Mail, you have to know the outgoing SMTP server settings. These settings are typically filled in automatically through the email client, but you can find them below if they're not.

In addition to sending mail using Simple Mail Transfer Protocol (SMTP), your email client needs to know how to download, or receive mail from your GMX Mail account, which is done through IMAP and POP3 servers.

You can read about that at the bottom of this page.

Note: Other email providers need SMTP server settings too but they aren't the same as GMX Mail's settings.
