Maintenance
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.

Dashboard Control panel delays for US email

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.

There is no delay in mail delivery, this is only affecting changes to email objects made via our customer control panel.

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.

    Web: San Francisco Opal14 not responding

    Opal14 (SFO shared hosting) is currently not responding. We're investigating at this time.

  • There was a second incident of the same type of problem but on a different site operated by the same customer. We've mitigated the problem to prevent it from occurring again and the server is stable at this time.

  • Opal14 is back online. The cause of the issue was high Apache RAM usage which resulted from a bad rewrite rule in a customer site. We've isolated the site and are working with the customer to correct the problem. We'll continue to monitor.
