Your server is not able or not allowed to connect to extrenal servers on port 25. is the server hosted on a dsl line? If yes, contact your ISP and ask if they allow outgoing connections on port 25. Another question is if your server is run on a static or dynamic IP address, almost all email providers block servers that are run on a dynamic IP.
