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.

  • Repairs to the host hardware are complete and the webmail server is back online.

  • The outage is caused by a problem with the physical host hardware of the VPS which runs the webmail service. The data center team is investigating and estimated 30-60 minutes of downtime.

    Emergency security maintenance / reboots on all AlmaLinux (EL9) servers

    Between 08:50 UTC and 09:10 UTC, we performed emergency security maintenance on all AlmaLinux (EL9) servers across all regions to apply critical security updates. This required rebooting the servers, which resulted in brief service interruptions during that window. The maintenance is complete and all affected systems are already back online.
