Some systems are experiencing issues
Maintenance
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.

    A misconfiguration in our IPv6 DNS settings was causing some mail providers (including Gmail) to reject some mail sent or forwarded from Opalstack's mail system over the past 3-4 days. The problem has been corrected.

    Email: USA Delays in US mail forwarding to @yahoo.com addresses

    An abusive network was sending a very high volume of messages to a @yahoo.com forwarding address hosted on Opalstack's US mail system. The high volume of mail has caused Yahoo to temporarily defer messages resulting in delayed delivery.

    We've blocked the abusive network and expect that Yahoo will begin to accept the deferred messages over the next few hours as their systems register the overall message volume decrease.

  • Yahoo are no longer deferring mail forwarded from our US MX servers.

  • Yahoo have begun to accept some mail forwarded from our US MX servers. We'll continue to monitor.
