unknownhost Exception

[Adewale Adebusoye]

Hello, i'm trying to write an email client, and when i try to connect to a server by means of pop, to check the inbox, i keep getting athe following exception:
javax.mail.MessagingException: Connect failed;
nested exception is:
java.net.UnknownHostException: pop.unlimitedmail.org

at com.sun.mail.pop3.POP3Store.protocolConnect(POP3Store.java:106)

at javax.mail.Service.connect(Service.java:234)

at javax.mail.Service.connect(Service.java:135)

and im using an smtp server called unlimited mail and the host name i used is "pop.unlimitedmail.org". and i have an account with these people.
So can anyone please help me out?

Either that's the wrong name for the server, or you can't get to that server from your computer. If you are sure it is the right name, then type

PING pop.unlimitedmail.org

at a command line, and see if you get similar errors there. Networking questions like this one are best handled by somebody who knows how your network is configured. This could be a DNS problem, or there could be a firewall or proxy server blocking the route, or several other things.

yeah i pinged their server and the request timed out. so what do you advise one to do? look for another smtp server?
