Answer 1

Someone is spoofing your email to send spam. There's not much you can do about it except mark it as spam and let it go.

Answer 2

These are spam bouncebacks that result from your spam blocker working for you. Senders of spam usually cannot receive email back at them, so your spam blocker's outgoing message comes back to you saying it is undeliverable. Usually this is done invisibly. Somewhere there is a check button to not notify you or send it to trash file.

Answer 3

they're attempting to tear-off your username and password. What I in lots of circumstances do in a case like that's deliver them bogus information, like Beavis for a username and kissmy@ss for a password.

Answer 4

change your password if you know you didn't send them
