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.

    At the present time there is a backlog of mailbox and email address changes for the US email system that are waiting to be processed. We expect this backlog to be clear within the next 2-3 hours.

    Email: USA Delays in US incoming mail

    At this time there is a high load condition on one of our US IMAP servers which is a variety of issues for some US mail customers including:

    • Delays in the receipt of incoming mail
    • Slow performance in IMAP mail clients
    • Slow performance in the Opalstack US webmail system

    We're working to mitigate the problem at this time and will update this post when more information is available.

  • All pending incoming US mail has been delivered.

  • The high load condition is resolved and the backlog of pending mail is being delivered.
