Just started having the same problem here, getting bounch back emails for undeliverable mail that I did not send. Ran virus scan, computer came back clean. Any way to stop these emails from clogging my inbox?
Do change your password
Make sure you set up your laptop and other portable devices to use SSL for email. This should make your email safer when you are not connected via Verizon.
Avoid WEBMAIL as it does not stay in https for all operations.
