I previously had my rochester.rr.com email set up on my iphone 4s, but then it stopped working for some reason. I deleted that email account and tried to set it back up again, but I keep getting the connectivity error that says "the POP server 'pop-server.rochester.rr.com' is not responding. Check your network connection and that you entered the correct information in the 'Incoming Mail Server' field." I've looked on the internet for what the settings should be, and it looks like I have everything set up correctly. Can someone please help me figure out how to get this set up on my phone?
