I got an static IP address from provider, that was enlisted in dynamic users and host list DUHL at sorbs.net. I registred there and managed to get address to exclusion exDUHL list.
When I try nslookup with x.x.x.x.dnsbl.sorbs.net, I correctly get an NX domain response.
However If I'm trying to send an email to 3rd party server which uses sorbs.net, I get rejected with reference to sorbs.net and result 127.0.0.10.
I also tried some of online mail spam list checking services and some of them are still showing sorbs.net
Is it possible, that results from dnsbl are cached, it's about 4days from listing in exclusion list?
