Relay access denied

[Predrag Ristic]

I''m trying to send a email message from my computer at work using these two classes:
SMTP.java

package pedja;

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.io.OutputStreamWriter;
import java.io.PrintWriter;
import java.net.InetAddress;
import java.net.Socket;
import java.net.UnknownHostException;

public class SMTP {

	private final static int SMTP_PORT = 25;

	InetAddress mailHost;

	InetAddress localhost;

	BufferedReader in;

	PrintWriter out;

	public SMTP(String host) throws UnknownHostException {
		mailHost = InetAddress.getByName(host);
		localhost = InetAddress.getLocalHost();
		System.out.println("mailhost = " + mailHost);
		System.out.println("localhost= " + localhost);
		System.out.println("SMTP constructor done\n");
	}

	public boolean send(FileReader msgFileReader, String from, String to)
			throws IOException {
		Socket smtpPipe;
		InputStream inn;
		OutputStream outt;
		BufferedReader msg;
		msg = new BufferedReader(msgFileReader);
		smtpPipe = new Socket(mailHost, SMTP_PORT);
//		if (smtpPipe == null) {
//			return false;
//		}
		inn = smtpPipe.getInputStream();
		outt = smtpPipe.getOutputStream();
		in = new BufferedReader(new InputStreamReader(inn));
		out = new PrintWriter(new OutputStreamWriter(outt), true);
		if (inn == null || outt == null) {
			System.out.println("Failed to open streams to socket.");
			return false;
		}
		String initialID = in.readLine();
		System.out.println(initialID);
		System.out.println("HELO " + localhost.getHostName());
		out.println("HELO " + localhost.getHostName());
		String welcome = in.readLine();
		System.out.println(welcome);
		System.out.println("MAIL From:<" + from + ">");
		out.println("MAIL From:<" + from + ">");
		String senderOK = in.readLine();
		System.out.println(senderOK);
		System.out.println("RCPT TO:<" + to + ">");
		out.println("RCPT TO:<" + to + ">");
		String recipientOK = in.readLine();
		System.out.println(recipientOK);
		System.out.println("DATA");
		out.println("DATA");
		String line;
		while ((line = msg.readLine()) != null) {
			out.println(line);
		}
		System.out.println(".");
		out.println(".");
		String acceptedOK = in.readLine();
		System.out.println(acceptedOK);
		System.out.println("QUIT");
		out.println("QUIT");
		return true;
	}
}

SMTPDemo.java

package pedja;


import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.io.OutputStreamWriter;
import java.io.PrintWriter;
import java.net.InetAddress;
import java.net.Socket;
import java.net.UnknownHostException;

public class SMTPDemo {

	 public static void main(String args[]) throws IOException,
     UnknownHostException {
   String msgFile = "c:/temp/proba.txt";
   String from = "[e-mail]";
   String to = "[e-mail]";
   String mailHost = "smtp.verat.net";
   SMTP mail = new SMTP(mailHost);
   if (mail != null) {
     if (mail.send(new FileReader(msgFile), from, to)) {
       System.out.println("Mail sent.");
     } else {
       System.out.println("Connect to SMTP server failed!");
     }
   }
   System.out.println("Done.");
	
}
}

and this is the console output:


mailhost = smtp.verat.net/62.108.127.4
localhost= PRISTIC/192.168.2.105
SMTP constructor done

No respectable mail server in the world accepts connections without authentication these days.

Unless it's your ISP and you're connected to that ISP while sending. My ISP certainly doesn't require me to login. It sees I'm using their connection so I can use their SMTP server, also for other email accounts.

So Predrag, the question is, are you using a verat.net connection at the moment? If so, contact them about the problem. If not, try entering your login credentials.

So you are, in fact, authenticated, as far as your ISP is concerned. :-)

True, true.
