Scheduled DE IMAP/POP3 email server downtime

On 24 September 2026 at between 07:00 am and 10:00 am UTC our network team will be relocating one of our mailbox storage servers to a new location within the data center.

The server will be offline during the relocation. As a result, some customer mailboxes will be unavailable for up to 3 hours during the relocation. Affected customers will be notified directly via email.

Affected customers will not be able to check their email for affected mailboxes during the relocation.

No incoming mail will be lost during the relocation. Mail that arrives during the relocation 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 relocation will not be stored as sent mail in IMAP folders on the server.

Customer websites will not be affected by the relocation.

We realize that the timing of this relocation may not be ideal. Customer who would like to have their mailboxes migrated to a different server in advance of the server relocation should contact the Opalstack support team to make the necessary arrangements.

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 email our support team and someone from our team will get back to you as soon as possible.

Web: Washington D.C. MariaDB offline on opal1

The MariaDB database service on opal1.opalstack.com (Washington DC shared hosting) is currently offline. We're working to restore service at this time.

  • We've seen no further issues with MariaDB on opal1.

  • The restore is 100% complete and the server should be online and functioning. We will continue to monitor.

  • The restore is 50% complete.

  • Following the integrity checks the database service remains unstable, so we're now rebuilding the system via a full dump/restore of all data. The database service will be unavailable until the restore is complete.

  • The database service is back online. We're now running integrity checks on customer databases.

    Microsoft blocking mx1.us.opalstack.com and smtp1.de.opalstack.com

    At this time mail sent from our DE SMTP server and mail forwarded from one of our US MX servers to outlook.com, hotmail.com, and live.com is being blocked by Microsoft. We're working with Microsoft to correct the problem.

    In the interim:

    • DE SMTP users can work around the SMTP block by configuring their clients to use smtp2.de.opalstack.com as their outgoing mail server.
    • US customers who use mail forwarding can work around the MX block by creating new MX records for mx2.us.opalstack.com with priority 5 and mx1.us.opalstack.com with priority 10.

  • The US MX block is now clear.

  • The DE SMTP block has been cleared.

    We're still working with Microsoft to clear the US MX block.
