DNSBL operators can and do get sued for their actions. Sometimes rightfully so. Further, accountability both for the block and its remediation, rests mostly with the admin who deploys the filters, whether it be something they've designed themselves, or choose to delegate to someone else (whether it be DNSBL, Brightmail filter downloads or A-V signature downloads etc). Which in our case is _me_. I don't get to blame others for _my_ choices. So, where's this accountability gap you keep talking about? I found out what our users thought of DNSBLs when I accidentally turned off DNSBL queries. We were flooded with hundreds of complaints about the spam. We get _far_ fewer complaints about false positives we have. So the real result of your suggestion is clear. You need to do what Jason suggests. _______________________________________________ Ietf@xxxxxxxx https://www.ietf.org/mailman/listinfo/ietf
