This may be configurable on your mail server.  Below is example 
headers of a spam that was sent to one of my users.  This user 
forwards their email from their uark.edu address to their AOL 
account.  I may not know the AOL email address in use, but I can look 
it up out of our ldap based on seeing  "myuser at uark.edu" in the 
headers as it passed from our mail exchangers to the actual mail 
server.  For thes regular complaining users, I have set up auto 
filters to ignore email from AOL about them and that leaves me with 
listserv mailing list false positives, and the legit stuff 
originating from our campus.
