Understood. The question I posed was whether there is anything useful in the SMTP logs if the OP's Exchange server is doing RBL rejections. Perhaps my wording was as clear as mud. A little Google searching leads me to believe that connection filtering-related data is logged in the SMTP log on Exchange 2003, but I don't know for sure because in my setup I can't test it. Even if it is, however, I wonder if there is anything useful beyond the sending IP address. If it is rejected because of a positive RBL hit, does the SMTP conversation ever get as far as the "Mail from:" or anything else that would help identify the rejected sender by email address? I kinda doubt it, and the OP might not know the sending sender's IP.
'Course all of this is moot if he doesn't have RBLs configured...
