Check message id header and other identical headers if there was any. They might be causing the problem.

Hello,
Today, I encountered a very strange phenomenon, and I'm not sure if Dovecot is involved:
A user sent an email at 11:55 AM with a PDF attachment. When checking their inbox in Outlook, they noticed that this exact PDF had somehow been attached to an email that was originally received at 10:50 AM. I verified the timestamps in the logs, and they are correct.
So essentially, the attachment from a later-sent email was appended to an earlier-received email sitting in the inbox-even though the two messages are completely unrelated.
I have never seen anything like this before-how is this even possible? Does anyone have any advice?
Thanks in advance!
