Just saw 29 ThOUSAND emails in my other email address

The most my regular account gets to is 2 thousand before I delete... but I have not checked my other account in about a year or so. YIKES!! It was an account I had set up many years ago to talk to a couple people from EP. I think I had a few emails still too, that I may have wanted :( But I just hit delete all. 29,000 emails. It would have taken an hour or so to get down to the really old emails to try to save. Oh well.. I can't do anything now.
