How to trace chain email initialted originated person

Can someone trace a Yahoo Email Address back to you? They can track it as far as your ip address - and if this can be traced to YOU (as in your home address), then YES! But if you're logging on at work/school - or ANYPLACE in public - then they can find out that SOMEONE used that account from that location ;););) But thats only if the sender used a mail client on his own computer. if the sender uses gmail.com web interface to send the mail, u'll just see googles server in the "recieved: from" section. not useful! Otherwise, they would be able to BAN the Trolls that just keep coming back day after day (   anything's possible. Or they can say "I know it's you, it sounds just like you!"   yes they can.. they can trace any email adress from any site back to its owner.   Well they can trace the email name and if your name is real on it(Can be changed in Options)they can trace your name .But if you have all false information the most most they can do is trace the IP adresss .
