Earthlink times out trying to get mail

When I try to get my e-mail it sets for quite some time and then says that pop.earthlink.net has timed out I can send e-mail with no problems, I have checked the pop setting they seem to be correct, I have checked mail2web and I have mail, I have deleted tbird and reinstalled a newer version, this didn't help, I have completely deleted and tried that and it still didn't work.
