Reason
Due to unexpected high e-mail traffic and a negative reputation of the surrounding network area, the acceptance of your e-mails was temporarily rejected.
Solution
An automated reputation check is being carried out on the basis of your DKIM domain, after which unhindered delivery to our system should be possible again.
We therefore ask for your patience.
If this does not help you, you or the person responsible for managing your system can contact us using the following form.
Please let us know the DKIM domain you use to sign your e-mails.
