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 US SMTP blocked by outlook.com

Our US SMTP server smtp.us.opalstack.com is currently on a Microsoft block list used by the following domains and their non-US equivalents:

  • hotmail.com
  • live.com
  • msn.com
  • outlook.com

We're working to get the server delisted at this time.

  • Microsoft is no longer blocking our US SMTP.

  • Microsoft has responded saying that our US SMTP will be removed from the blacklist within the next 24-48 hours.

  • Microsoft have responded to our inquiry. It appears that the recent influx of WebFaction customers 🎉 has caused a sudden increase our outgoing mail volume and that this is what triggered the block.

    We've verified via Microsoft's own postmaster tools that there have been zero complaints regarding mail from our US SMTP and have provided this data to Microsoft for consideration.

    We hope to follow up with a resolution to this issue as soon as possible. Thank you for your patience.
