I'm getting numerous spam complains but I'm finding the spam is going through our server to a forwarded address. For example spam is sent to firstname.lastname@example.org and is forwarded to email@example.com. AOL complains that the e-mail comes from our server. Apparently the headers do not contain the information from the original sender so they think we are sending the spam. How do we make the original information go on with the e-mail so AOL will know where the spam comes from instead of blaming us.
