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 DE IMAP service offline

Our IMAP service in Germany has been offline since around 11:30 AM 12 Feb 2020. We're working to identify the cause at this time.

  • The disk array rebuild is complete.

  • The failed disk has been replaced and the DE IMAP service is operational at this time.

    Disk performance may be slightly degraded while the disk array rebuilds.

    We'll post a final update when the array rebuild is complete.

  • The DE IMAP service is back online. We'll continue to monitor.

  • The DE IMAP server has experienced a disk failure. The storage array is currently rebuilding. We'll update with an ETA as soon as we have one.
