Java Mailing program working in intranet but not in internet

Hi everyone,

I have a little problem with my java mail coding.
While i was using java mail coding in local netwok(intranet) properly executing.
But i was used in internet, it is not working.
I told my problem(java mail is not working prperly) to my server maintainer(service provider).
They told "we loaded all mandatory jar files in Tomcat server please verify your coding"
And told " please check your smtp protocal" and wrote code
u shoud use smtp as 25

other things asp and php coding are not supported in java server ..
u should send mail coding through jsp
Please check once & let us know if any problems !
Please let us know the error URL / Path if you have any more problems, thanks

please refer my coding and tell what is wrong with coding

I can't really see anything wrong with this code although I am unable to test it. Have you got any further with it?

Have you set:

Code :

---

[COLOR=#8b0000]props.put("mail.smtp.host", host);[/COLOR]

---

To the correct SMTP host and port? I think it should be:

Code :

---

[COLOR=#8b0000]props.put("mail.smtp.host", 25);[/COLOR]

---

Assuming that mail.smtp.host is your SMTP host.

How do you access the Internet? Any proxy involved? Is the SMTP server outside the Intranet?

I have this simple SMTP program working - both intranet and internet.

See if this works for your needs.

Code :

                   public void sendMail()
	{
		try
		{
    		Socket s = new Socket(this.getSmtpServer(), 25);
 
    		InputStream inStream = s.getInputStream();
    		OutputStream outStream = s.getOutputStream();
 
    		in = new Scanner(inStream);
    		out = new PrintWriter(outStream, true /* autoFlush */);
 
    		String hostname = InetAddress.getLocalHost().getHostName();
 
    		receive();
    		send("HELO " + hostname);
    		receive();
    		send("MAIL FROM: <" + this.getFrom() + ">");
    		receive();
 
    		// Parse the Test Plan names which are comma seperated
    		String patternStr = ",";
    		String[] fields = this.getTo().split(patternStr);
    		for (String value : fields)
        		send("RCPT TO: <" + value + ">");
 
    		receive();
    		send("DATA");
    		receive();
    		send("subject: " + this.getSubject());
    		send(this.getMessage());
    		send(".");
    		receive();
    		s.close();
		}
		catch (IOException e)
		{
			e.printStackTrace();
		}
	}
 
	public static void receive() throws IOException
	{
		String line = in.nextLine();
 
	}
 
	public static void send (String s ) throws IOException
	{
		out.print(s.replaceAll("\n", "\r\n"));
		out.print("\r\n");
		out.flush();
	}
 
	private static Scanner in;
	private static PrintWriter out;
