I'm using Mail. Up til now, I've had no problems. Recently my paypal acct was accessed by a third-party overseas. Since then I am getting nearly 200 e mails a week that are marked undeliverable. The e mails are almost always addressed to weird overseas addresses but are probably bogus anyway. I don't know how this happened or how to fix it. I can't even check my e mail on my iPhone because I'll be deleting mail from Mail Delivery System for ever. Is there ANYTHING I can do?
