If this was an actual email sent TO your email address, it can probably be tracked and the originating IP address uncovered. From there I can match up the IP address with the list of users here and determine who it is.

If the email contains material of such a nature that you described then that person would be banned because we don't permit our users to harass other users to that extent.

Send me the exact email address they used and a copy of the message. From there I'll get back to you with some further instructions on how to pull up the info about where it came from.
