I spent a few minutes organizing my email by moving some messages in Apple Mail to an IMAP server running on my local system. I dragged the email (3000 pieces) to the IMAP server, it seemed to work just fine, and then I noticed about 10 emails from today just gone. No undo. No evidence as to why they vanished. Spotlight finds no evidence of them anywhere. They’re gone.
I rely on my email for sooooo much. Fortunately, I have a backup of nearly everything on Gmail. Ugh.
