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.

    Dashboard DNS issue for opalstack.com causing control panel delays and other issues

    At this time there is a delay in processing new items and changes in the control panel at https://my.opalstack.com/. We're looking into it and will follow up as soon as possible.

  • DNS has propagated on our end and the backlog of pending control panel changes is now clear.

    If you have DNS problems like "host not found" when accessing any Opalstack systems then please try flushing your local DNS cache: https://www.wikihow.com/Flush-DNS

    For further assistance please email the Opalstack support team.

  • We've identified the problem as 2 name servers which were failing to return records for opalstack.com hostnames. We've removed those name servers from our pool and are monitoring while the DNS change propagates.
