mail server Yahoo ?

How can I determine what is real name for mail server when I have 'servername.com'

I am not sure.. You can try to pinging mail.servername.com and if you get a response.. that is the mail server. (that is the usual combination)

BTW: Yahoo it is mail.yahoo.com

On Unix systems, you can type "host myserver.com", and that'll display the addresses of the server(s) who are responsible for the site's email. Then telnet to that server's port 25.

What you need to do is lookup the MX records for the server.  There could be multiple in which case you can send mail to any of those hosts.  On NT and Win2K you can use nslookup

I have installed javamail 1.2 is it possible to find some example which sends mail without me to have think how and why.

I found some examples but they ask me to provide smtp server.
And that brings me back to how to find one with servername.com

I try to use nslookup but results i got back for yahoo.com dont have a port 25 to connect !

Doesn't your hosting service provide an email server (smtp server) to you?

There are some free smtp servers out there:

[though I am not sure if they work anymore]

Proton, yahoo has got a pop server and smtp server running. as they don't want any mails going out from their smtp server without proper
verification, they have put a restriction that u shud log on to their pop server first, then only u will have access to their smtp server.

yahoo pop server  - pop.mail.yahoo.com
yahoo smtp server - smtp.mail.yahoo.com

u can use the below given code to test out the same. pls note that this is juz a test code and itz written specifically for yahoo(it tries to connect to pop, b4 tryin to send a maiil thru smtp).

compile the code and make sure that u'r classpath is pointin to mail.jar and activation.jar(which comes as part of javamail 1.2 and jaf) and u shud have an account with yahoo :-)

invoke the code as given below,

java SendMessageExample pop.mail.yahoo.com smtp.mail.yahoo.com <u'r yahoo username> <u'r yahoo password> <from mail address> <to mail address>

import java.io.*;
import java.util.Properties;
import javax.mail.*;
import javax.mail.internet.*;
public class SendMessageExample {
     public static void main (String args[]) throws Exception {
            if (args.length != 6) {
                System.err.println("Usage is : java SendMessageExample <pop-Hostname> <smtp-Hostname> <username> <password> <fromAddress> <toAddress>");
                 return;
           }

          String pop3Host = args[0];
          String smtpHost = args[1];
          String username = args[2];
          String password = args[3];
          String from = args[4];
          String to = args[5];
          Properties props = new Properties();
            props.put("mail.smtp.host", smtpHost);    
          Session session = Session.getInstance(props, null);
          Store store = session.getStore("pop3");
          store.connect(pop3Host, username, password);
           MimeMessage message = new MimeMessage(session);
             message.setFrom(new InternetAddress(from));
           message.addRecipient(Message.RecipientType.TO, new InternetAddress(to));
               message.setSubject("Hello JavaMail");
           message.setText("Welcome to JavaMail");

             Transport.send(message);

          store.close();
     }
}

hth
kewl

P.S: please note that this is juz test quality code :-)
