US IMAP email server downtime

On 22 July 2026 at 10:00 am US/Central time (UTC -5) one of our US IMAP email servers will be shut down for infrastructure maintenance. The server will be offline during the maintenance and the expected downtime is 6 hours.

Affected customers will be notified individually via email.

No incoming mail will be lost while the server is offline. Mail that arrives during the maintenance will be deferred and delivered once the mail server is back online.

We realize that the timing of this relocation is not ideal. If you have business-critical mailboxes and would like them to be available during the maintenance then please email support@opalstack.com or reply to this message to make arrangements to have your mailboxes migrated to a different IMAP server prior to the scheduled maintenance date.

If you have any questions or concerns regarding this maintenance then please email the Opalstack support team for assistance.

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.
