I create a new account at www.dnswl.org <http://www.dnswl.org/> and add my primary domain in their portal.
I also request them to add my outgoing SMTP IPs (I think they manually check it before add). To query their database, do I have to ask them to add my resolver's IPs too? It looks like they allow access from "unknown" IPs (test it with nslookup), but I want to make sure that registering resolver's IPs is not needed to avoid them block the requests made by my resolvers in the future.
