Duplicate emails
Subject: Duplicate Emails with Identical Message-ID in Yahoo Mail
Message:
Hello,
I am experiencing a problem with duplicate emails in my Yahoo Mail account. The same message is appearing twice in my Inbox with the exact same timestamp. When I checked the raw headers, I confirmed that both copies have the same Message-ID, which indicates the duplication is happening on Yahoo’s servers rather than from the sender or my email client.
Details:
- Duplicates appear in Yahoo Mail web and in Outlook for Windows.
- The same duplicates do not appear in my iPhone Mail app (Apple Mail seems to collapse them).
- This issue started recently and is affecting multiple incoming emails.
- Example Message-ID: <insert one of your actual Message-IDs here>
Could you please investigate this server-side duplication and advise on a fix?
Thank you,
Joseph
