I'm fairly sure it's the dynamic ip that's causing it. Below is the
bounce message. My machine passes the open relay tests(does not relay)
and port 25 is not open to the outside anyway. I am on a dynamic ip, so
I assume that's the cause.

I don't think tying a domain to my ip will work. If they're going by a
list that RR has of dynamic ip's, it will still be there even if I have
a domain.

Even if I get a domain, unless I can get RR to set up a reverse look up,
the reverse will still resolve to their dynamic name. Unless I'm
misunderstanding how resolution works, the owner of the IP address
provides the reverse, if there is one. Owners of the name provide the
name resolution. No matter how many domains I tie to my IP, RR still
owns the address and provides the reverse lookup. I could be wrong about
that.
