Check up with your ISP or the server provider if the POP settings have changed.

Usually, the POP SMTP ports are a problem (the ISPs block it if they find that it is being used for SPAM).

The provider may have switched ports from 25 to something else and/or implemented SSL/TLS to make it more secure.

The other option is to try a client like Thunderbird and try to resolve if the problem is local to the machine, or to the ISP / Provider.

Have you installed any firewall etc or configured any firewall to intercept outgoing connections? This could be another reason.

I have also seen that most ISPs dont allow more than one connection for POP. So if you are using two clients to connect and get your email, the second one might get stopped while the first one finishes.

Have you checked to ensure the password is valid? With password mismatches you normally get an error saying that your password is invalid.
