Just as a side note, if you still have the email, 
you might look into it and report them to their 
provider. If you look at the message header, you 
may be able to find their email host. I got a 
similar-but-different fake email from someone 
using Starband, and reported them, since they 
were violating Starband's TOS. Who knows if it 
had any effect, but at least the effort was made.
