Scheduled DE IMAP/POP3 email server downtime

On 24 September 2026 at between 07:00 am and 10:00 am UTC our network team will be relocating one of our mailbox storage servers to a new location within the data center.

The server will be offline during the relocation. As a result, some customer mailboxes will be unavailable for up to 3 hours during the relocation. Affected customers will be notified directly via email.

Affected customers will not be able to check their email for affected mailboxes during the relocation.

No incoming mail will be lost during the relocation. Mail that arrives during the relocation will be deferred and delivered once connectivity to the mail server is restored.

Email forwarding and SMTP services will not be affected, however messages sent via SMTP during the relocation will not be stored as sent mail in IMAP folders on the server.

Customer websites will not be affected by the relocation.

We realize that the timing of this relocation may not be ideal. Customer who would like to have their mailboxes migrated to a different server in advance of the server relocation should contact the Opalstack support team to make the necessary arrangements.

We'll update our status page at http://status.opalstack.com/ at the beginning of the maintenance window. To be informed of system status updates automatically please subscribe at https://status.opalstack.com/subscribe.

If you have any questions or concerns regarding this maintenance then please email our support team and someone from our team will get back to you as soon as possible.

Past Incidents

6th January 2024

Email: Germany German MX servers are on Hotmail block list

mx1.de.opalstack.com and mx2.de.opalstack.com are listed on the Hotmail block list. As a result, mail forwarded to Hotmail domains like hotmail.com and outlook.com is being bounced back to the sender.

We're working to have the servers removed from the block list and will update this post when that is done.

In the meantime, customers who have forwarding addresses which forward to Hotmail domains are advised to forward to an alternate address or direct mail to an Opalstack mailbox to ensure that they receive their mail. Instructions for updating email addresses are available in our user guide at: Editing Email Addresses

  • The MX servers have been removed from the block list.
