Ed wants to know if his ISP keeps his email. Leo says it does if he's using IMAP. So if you are using Outlook and you're using IMAP, it will download a copy of the email and keep a copy on the server. And they have to for several years by law. POP3, by contrast, downloads the mail to your computer and deletes it from its server space. Leo really isn't a fan of keeping your ISP as your main email service. He uses a third-party payment service called FastMail. That way, he can change ISPs at any time, and it doesn't affect his email at all. And it's not that expensive either.
