We're doing maintenance on our mail servers on 10-03-2021 from 04:00-06:00 am CET.
While we're upgrading the server that hosts your mail, your email will be temporarily unavailable. All emails sent during this time will be delivered afterwards, so no email will be lost.
If you experience issues with your email after the maintenance window has completed, please contact us on chat or email here:
