I've been managing the same WHM server for 6 years in a row now and out of the blue, without any update done recently (last WHM update was like 1 week ago) I just received 2671 old emails in one of the inbox that's on that server. For no apparent reason. I've been using Thunderbird with the same 4 inboxes for years and I've never seen that. Has anybody seen that recently with cPanel? I have not done any modification to that inbox nor the computer I'm getting my emails with, absolutely no change whatsoever.
