I get some long deleted mail messages (from 2005!) reappearing in a smart mailbox. The weird thing is they only appear in the smart mailbox and they are greyed out. They are nowhere in the message folders on the hard disk and don't show up in the real mailboxes. When I try and delete them I get a message saying they cannot be moved to trash. When I click on them I get a message saying I need to re-download them from the server. They are not on the server. My account is POP

I've run every gizmo I can find to vacuum and rebuild my mail. I deleted the smart mailbox and started a new one with a new name but as soon as the mailbox rules specified the criteria which included these old messages they were back!

Any ideas? I'm with 10.4.11 and Mail 2.1.2
