Jeff is about to close down an old email account and he wants to be able to delete all the old email at once. Leo says that if the email system is POP, he can set the email client to delete from the server once it has downloaded to it. If it's IMAP, that email is kept on the server after downloading. So he'll have to do it the hard way. If he can turn on POP3, he can then just download it and it will delete all at once afterwards. If not, he'll need a third party app, and there are plenty. Google makes one.
