not really exchange related. i was wondering how spammers are able to forge the 
TO: header of an email so that you get the email even though its not addressed 
to you.

like if i'm joe@xxxxxxxxxxxxxx, i get an email to my inbox addressed only to 
bob@xxxxxxxxxxxxxx or bob@xxxxxxxxxxxxxxxxxxx?
is it that the envelope headers are addessed to me but the email TO: headers 
are changed?

Is this this the same thing as when you get spam and the TO: headers say 
"undisclosed recipients"?
