Maintenance
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.

    Email: Germany Incoming mail problems in Germany

    We're receiving reports of slow mail delivery in our German mail system. We're looking into it at this time.

  • The disk array rebuild is complete and the server has been stable since our last update.

  • The DE mail service is back online at this time. The main issue was heavy load caused by the very high volume of deferred mail the resulted from the mail loop. This was exacerbated by the degraded disk array.

    The networking issue was unrelated but has been resolved.

    The disk array is still rebuilding but the server is operating normally. We'll continue to monitor until the rebuild is complete.

  • There seems to be multiple issues related to the DE IMAP server:

    1. A forwarding loop was causing delivery delays for the past few hours.
    2. A degraded disk array was impacting system performance
    3. A failed network switch is currently blocking network connectivity

    Our data center team is working on restoring connectivity at this time.

  • The DE IMAP server is now offline for a filesystem check.
