-> Actually, if you see REAL spam from hotmail, they are very responsive about
-> removing that user. Unfortunately, since it is so big (like aol.com), most
-> people just put a bogus reply email from AOL.com or hotmail.com. nothing
-> you can do about that. Watch the headers and block the people that support
-> spam. You will find a suprising trend in what servers it really comes
Actually the bigger problem is the forged return addresses. Using sendmail
we do not allow our users to put bogus domain names in the FROM field.
However, others don't check so closely and thus the problem propogates.
Many of the spam messages we block, which the FROM address is aol.com
actually originate elsewhere.
