At first glance, you are attempting to use google's POP3 server rather than their SMTP server to send e-mail. They use a different host to send e-mail.

You may also want to check and make sure that the hostname is resolving to an IP address from the host you are running the program on. You can use a tool like nslookup to make sure.
