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.
