Hej Kim.
Jeg har fået denne meddelelse fra GMX.com:
Dear Peter,
You have recently attempted to integrate your GMX mailbox into an e-mail program such as Outlook or your smartphone's pre-installed e-mail app. Unfortunately, that attempt was not successful, the possible reason for which will be detailed below.
GMX.com
The POP3/IMAP/SMTP protocols which are required for e-mail programs are deactivated by default for safety reasons. This is to prevent unauthorized persons from accessing your mailbox via POP3/IMAP/SMTP.
The protocols will also be deactivated if you have set up your GMX mailbox for use in an e-mail program before, but you have not used it for a longer period of time.
To use this function, you must set up the protocols or reactivate them in your mailbox settings. You will find step-by-step instructions in the GMX Help Section.
Otherwise, we recommend using the GMX App for iOS or Android.
This application also offers direct access to your mailbox, but it does not use the unsafe POP3/IMAP/SMTP protocols.
Thank you for your cooperation.
Your GMX Team
Jeg vil nu afprøve denne "aktivering". Du hører nærmere

hilsen Peter
