Check your outgoing server name, the port number and SSL setting, and the authentication setting. Open the Account Settings dialog, double click on the affected email account. Is the server name correct? Click the More Settings button. Check the authentication settings on the Outgoing server tab, and the port number and SSL settings on the Advanced tab.

there is several reason for such case, but mainly make sure of your pop3 server  is available online and your ISP is not blocking port110

some isps use relays so if this is the case, you should use ISP server relay instead of your mail server address
