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.

Past Incidents

12th September 2024

Web: Washington D.C. opal12 blocked by Malwarebytes

At this time opal12.opalstack.com (Washington DC shared hosting) is being blocked by Malwarebytes. The cause was an outbound SSH attack from a compromised customer shell account which caused the server to be listed in a major block list. As a result visitors who use Malwarebytes may see a warning when visiting sites hosted on opal12.

We're working with the block list operator to have the server delisted and expect to have this resolved within the next couple of days.

In the meantime, you may be able to work around the problem by adding your site domain and/or server IP 207.244.121.250 to your Malwarebytes exception list.

  • opal12.opalstack.com is no longer blocked by Malwarebytes.
