I am using RoadRunner here in Houston and am having the same problem. Something is blocking me from receiving my emails. My settings weren't changed to the 127.0.0.1, but I entered my settings as in the picture, but still get an error code. Just for an example, I put in as account name jdoe@houston.rr.compop.houston.rr.com and I still get an error message. Before it said my popserver couldn't be found, now I get an error about the 127.0.0.1 This is why my name is TechNoob, lol.
