Scheduled US IMAP email server downtime

On 26 August 2026 at between 11:00 am and 4:00 pm US/Pacific time our network team will be performing infrastructure maintenance. During this 5-hour window, network connectivity to one of our US IMAP/POP3 email servers will be interrupted for up to 1 hour.

As a result, some customer mailboxes will be unavailable for up to 1 hour during the network interruption. Customers who will be impacted by the interruption have been emailed directly.

No incoming mail will be lost during the interruption. Mail that arrives during the interruption will be deferred and delivered once connectivity to the mail server is restored.

Email forwarding and SMTP services will not be affected, however messages sent via SMTP during the interruption will not be stored as sent mail in IMAP folders on the server.

We'll update our status page at http://status.opalstack.com/ at the beginning of the maintenance window. To be informed of system status updates automatically please subscribe at https://status.opalstack.com/subscribe.

If you have any questions or concerns regarding this maintenance then please contact the Opalstack support team.

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.
