We recently re-enabled DNSBL checking in FPE and since then we have had a drastic increase of legitmate users complaints about blocked emails, from numerous organizations. I can certainly appreciate that the problem is on their end, but it only seems to
be mostly PBL listings.
Is there any powershell or registry hack I can use to continue to subscribe to DNSBL checking for SBL, XBL but no longer check against PBL listings?
I dont want to disable DNSBL checking again, but if I cant get this under control and the complaints keep coming, Ill have to disable it again. Making IP based exceptions is my workaround for now.
