Often I receive mail that was not sent by the person that is in the 
from: line. Many people also get mail that claims to be sent by me. I 
even get myself mail sent by me often from places that I might wish to 
visit, but haven't done so yet.
What I never fully understood is if this is legal or not. I know it is 
easy to do, and hard to track down, but I would expect it to be illegal 
anyway. Anyone here knows?
