This is one of multiple messages I've received from River Gold Casino

I buy a lot of dropped domains (at the moment I've got about 400), and my spam mail is massive (1,500- 2,000) and that's after I've blocked all mail from hotmail, msn, yahoo, meloo and a few others (this removes about 200 items). Because of this, I'm never sure if the mail is really spam or from a previous opt in list. It would be nice if it were possible to bounce mail back and actually get my address deleted automatically.
