I received a very insulting email sent to me via an "e-sult" website. The source email address was clearly made up just to send me the message, but is there anyway to tracking the real source - it was so bad I'm thinking of going to the police with it.
If the email came from a web site then the header will not information about who is ultimately responsible, only the account used by the website itself. This is the whole purpose of this type of site - to allow people to send offensive stuff at one degree of removal.
