Scheduled downtime for opal9

On 20 May 2025 from 0700 - 1100 UTC opal9.opalstack.com (Frankfurt DE shared hosting) will be taken offline and relocated to a new rack within the data center.

Customer websites, files, and databases hosted on the server will be unavailable during the relocation.

Customer email accounts will remain online during the relocation. The server IP address will not change.

The maintenance window is 4 hours but the data center team will do everything possible to minimize the downtime within that period.

If you would like to move to a different server prior to the scheduled downtime, please email the Opalstack support team to request a migration.

We apologize for any inconvenience. If you have any questions or concerns regarding the maintenance then please email our support team and someone will get back to you as soon as possible.

Email: Germany German SMTP blocked by Microsoft

On December 18 2021 at 19:30 UTC Microsoft began blocking mail sent from smtp.de.opalstack.com to domains that use the Microsoft 365 email system.

Microsoft's own IP reputation and junk mail reporting systems indicate that there are no problems with smtp.de.opalstack.com so we've reached out to them for answers.

We'll update this post as soon as more information is available.

In the interim as a possible workaround customers may create a new mailbox on our US mail server and use that temporarily for their outgoing email authentication.

  • We've still not received confirmation from Microsoft that the block was lifted, but we've seen no further blocking activity since 23:50 UTC on 20 December 2021 so we consider this incident to be closed.

  • Microsoft began accepting mail from smtp.de.opalstack.com as of 23:50 UTC on 20 December 2021.

    We're still awaiting official confirmation that the block has been lifted.
