Our email server, exchange 2000, was accidently put as an open relay and has since been fix. Although I have sucessfully removed our IP from most lists, I can not figure out how to remove it dsbl.org. To be more exact, It dsbl.org requires you to have set up the email address postmaster@[ip Address] and I am not sure how to do this. (I am still fairly new to exchange server). It was something about being RF Compliant Just looking for a white paper or something on how to set this up.
