DSN, Deny Null Sender, is prohibited by RFCs, and is a part of the RFCs I completely agree with. On top of that, I have never had a single user complaint over that RBL. I try to keep things below 1 complaint a month. What you could do is some testing. Use one RBL at a time with the warn_if_reject tag. Then check your logs and research the results. --Eric
