Maintenance
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: USA US webmail performance issues

We're aware that the US webmail server has been having intermittent timeout issues, particularly during US business hours.

We're working to resolve this but we expect that it will take at least a couple of weeks. Our recommended workaround in the interim is to use a desktop mail client or to run your own webmail server separately from our managed webmail instance.

Desktop email client configuration info is available in our user guide at: Email Client Configuration

If you'd like to run your own webmail server setup instructions are available at: HOWTO run your own Roundcube webmail server on Opalstack

  • We've seen no further performance issues on the US webmail system since implementing the new proxy, so we consider this issue to be resolved.

  • We've deployed a new IMAP proxy on the US webmail server and the performance seems much better at this time. We'll continue to monitor.
