I've had a lot people telling me that they are having emails sent to us bounced due to their IPs being blacklisted. I have a few RBLs I'm using and I'd like to know which RBL is blocking them. I've done the usual mxtoolbox check along with the Sophos IP reputation check and a lot of them are coming back clean. I figured I'd check out the logs, (Thanks LuCar Toni for directing me to the smtpd logs and not awarrenmta) so I downloaded smtpd_main, error, panic and reject and had a look. I'm seeing a lot of "Sophos Anti Spam Engine has blocked this Email because the sender IP Address is blacklisted" and "Rejected: sender IP is RBL listed". What's the difference? There is no mention of which RBL is causing rejections, is that info not logged anywhere?
Thanks
Gary
