SOCKS4, SOCKS5 Proxy for POP3

Demonstrates how to communicate with a POP3 server through a SOCKS4 or SOCKS5 proxy. Java

    // To use a SOCKS4 or SOCKS5 proxy, simply set the following
    // properties prior to making any calls that communicate with
    // a POP3 server:
    // The SOCKS hostname may be a domain name or 
    // IP address:
    mailman.put_SocksHostname("www.mysocksproxyserver.com");

    mailman.put_SocksPassword("myProxyPassword");
    // Set the SOCKS version to 4 or 5 based on the version
    // of the SOCKS proxy server:
    mailman.put_SocksVersion(5);
    // Note: SOCKS4 servers only support usernames without passwords.
    // SOCKS5 servers support full login/password authentication.

    // Set the POP3 server's hostname

    // Set the POP3 login/password.
