Monitoring - Status: Monitoring Date Reported: November 28, 2025

What’s Happening:
Some emails sent from Rebel Cloud Email to Yahoo addresses may be delayed or returned. Clients may see a message like:
> “This mail has been blocked because the sender is unauthenticated. Yahoo requires all senders to authenticate with either SPF or DKIM. Authentication results: DKIM = FAILURE - SPF = FAILURE.”
This is due to stricter email verification policies on Yahoo’s side.

What We’re Doing:
Our Email Team is actively working on improvements to reduce these delivery issues. No action is required from your side, and other email recipients are not affected.

Next Steps:
We are monitoring the situation closely and will provide updates as soon as more information is available.

Identified - Identified Issue (External to Our Services): We are aware of an issue affecting some customers who use Plesk Email Hosting and Cloud Email Hosting when connecting their existing email accounts to the New Outlook for Windows application.
----- Important: Our email servers and services are operating normally. The issue appears to be related to Microsoft’s New Outlook for Windows app and how it handles IMAP/POP authentication for certain existing accounts.
----- What Customers Are Seeing: Some users receive error messages such as: “Something went wrong, try again.” “You may need an app password.”
These errors occur even when the correct password is used and meet the updated security requirements.
------ What We Have Verified: - Our email platforms (Plesk and Cloud Email) are functioning normally.No server-side errors or authentication failures are occurring.
- Newly created email accounts connect to New Outlook successfully.Existing accounts fail specifically within the New Outlook interface.
- Switching to Classic Outlook resolves the issue immediately.
------- Temporary Workaround: To continue using email without interruption, customers can switch Outlook back to the Classic Outlook interface:
-------- Impact: This issue is limited to the New Outlook for Windows app.
Email continues to work normally on our servers and through Classic Outlook and other email clients.
------- Next Update: We are monitoring the situation and will provide updates if Microsoft releases an adjustment or clarification regarding New Outlook’s authentication behavior.
