Looking at the SMTP Log in Mail Manager on my newly-upgraded ASG V8, I see RBL rejection messages citing black.rbl.ctipd.astaro.local and grey.rbl.ctipd.astaro.local. I presume these are composite RBLs used internally by the ASG, but my question is: if a valid recipient finds himself being rejected, how can he (or I) now find out which actual RBL caused the rejection?
