I've run into a similar mail problem when I use the MyYahoo mail preview page. Beginning around Feb 2nd, when new mail arrives, it also displays old email that was previously deleted or moved. When I click on the old ones, I get a message viewing error advising me it can't be displayed. When I move or delete the new email, then click "refresh", the screen clears until the next email comes in.. then it displays all the old ones again. Anybody else having this problem, or I am the only one?
