<QUOTE>here is the solution that you can send mail through a proxy server
Properties p = System.getProperties();
         p.setProperty("proxySet","true");
         p.setProperty("socksProxyHost","192.168.155.1");
         p.setProperty("socksProxyPort","1080");</QUOTE>
I installed CCProxy in my machine and gave my own IP address ( 1. LAN IP and 2. IP from whatismyip.com; both works ) and port number. It works. But I gave IP addrss of my friend ( 1. LAN IP and 2. IP from whatismyip.com; both NONE work ) who got CCProxy and in his machine. But doesnt work ( throws Below exception).
Exception in thread "main" javax.mail.MessagingException: Could not connect to SMTP host: smtp.gmail.com, port: 465;
  nested exception is:
        java.net.SocketException: Can't connect to SOCKS proxy:Connection timedout: connect
        at com.sun.mail.smtp.SMTPTransport.openServer(SMTPTransport.java:1391)
        at com.sun.mail.smtp.SMTPTransport.protocolConnect(SMTPTransport.java:412)
        at javax.mail.Service.connect(Service.java:310)
His IP address is found with whatismyip.com. I guess its a problem with IP address. What am I doing wrong here ?? Could some one help me out please ?

Answer 1

I believe we can give some other socks proxy ip address too, other than CCproxy machine ip address If I am correct. Is there any specific way to use the socks server ip address ( such as provided in many websites, used for open relay) ? I tried some of them, which I am able to ping. But still I get the same exception like connection request timed out.
