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.

Email: USA Slow IMAP performance

At this time we're importing hundreds of gigabytes of mail for new customers migrating from WebFaction. This is causing heavy load on our IMAP servers so you may see slow performance in our webmail system, IMAP clients, and POP3 downloads over the next few days.

We'll update this post when the imports are complete.

  • The US IMAP service is currently under heavy load while importing mail for new customers.

  • All pending mail imports have been completed and the IMAP servers are operating normally.

    Web: Dallas Recurring attacks on opal4

    opal4.opalstack.com in Dallas TX USA is currently not responding. We're looking into it.

  • Opal4 is stable at this time.

  • Opal4 is not responding, likely another attack. We're investigating.

  • Opal4 is back online. The disruption was caused by another network attack. The replacement server will be set up soon and we'll start scheduling the transition.

  • Opal4 is currently not responding to ping, investigating.

  • Opal4 is stable at this time.

  • Opal4 is back online.

    The earlier assessment of an external network problem was incorrect, this appears to have been another network attack on Opal4.

    The attacks that have taking opal4 down haven't seemed to be particularly massive - similar attacks happen on other shared hosts in our infrastructure and those machines are fine. Because of this we're planning to replace opal4 in the coming weeks. We'll contact all affected customers individually with the details as we finalize the plan.

  • Opal4 is offline due to a network problem in the Leaseweb Dallas TX data center. We're awaiting further updates from them at this time.

    Dashboard Dashboard was not pushing changes

    Four hours ago at approximately 17:30 UTC today on 09 Dec 2020 a bug was introduced into our admin dashboard that blocked the ability for new changes to be pushed out to servers.

    This affected all dashboard operations: new apps, new sites, email, domains, etc were held back due to the bug.

    It's been corrected and most items should be caught up within the next 30 minutes. Let's Encrypt certificates may take a while longer but will eventually go through.
