I had the same thing happen with Comcast email. They 'upgraded' their mail service a couple years back with enhanced spam capture and turned it on automatically. Had many emails get caught in it that I really wanted. Finally went to the Comcast website and logged in to my email there, and was able to get a few that hadn't been deleted yet.
Eugene, if you are using Comcast, log in to your email on the Comcast web page and see if stuff is stuck there, and also check the spam settings (I turned everything off, and deal with spam at my computer).
