The documentation for the AOL feedback loop processing feature states: In the future, other ISPs may be supported, but for now only AOL is supported, so please do not enter any other ISPs in the configuration. It will not work unless they use the exact same format as AOL. Lately, we have been receiving AOL feedback loop reports for other domains serviced by AOL mail servers, including, but not limited to: aim.com and netscape.net. Can we simply add these domains to the SPAM_FEEDBACK_PROBE statement in our site configuration file? SPAM_FEEDBACK_PROBE="AOL.COM,AIM.COM,NETSCAPE.NET" -- Paul Russell, Senior Systems Administrator OIT Messaging Services Team University of Notre Dame
