Send email in android using JavaMail API with smtp

问题:

I have gone through this question, it works well with its own case using SSL

and I have also tried this one, which somehow suits to my need but it won't worked in my case.

I have also read this topic but still not able to send a email without using SSL in my code.

Everytime I send a mail it says "Exception 554, Mail Refused"

what i really need is to use::

mailhost: "smtpout.secureserver.net"

port-no: 25

Thanks,

Haps.

Firstly use Mail.jar, activation.jar, Additional.jar file Upload in Your project

Use this Mail Class

package com.technosoft.AkashEmailAddress;

import java.io.ByteArrayInputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import java.util.Date;
import java.util.Properties;
import javax.activation.CommandMap;
import javax.activation.DataHandler;
import javax.activation.DataSource;
import javax.activation.MailcapCommandMap;
import javax.mail.BodyPart;
import javax.mail.Multipart;
import javax.mail.PasswordAuthentication;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeBodyPart;

import android.util.Log;


public class Mail extends javax.mail.Authenticator { 
  private String _user; 
  private String _pass; 

  private String[] _to; 
  private String _from; 

  private String _port;

Mail class has send() Method use in Your Main class

Main class extends Activity{
    Mail m=new Mail("[e-mail]","XXXXXXX");
    @SuppressWarnings("static-access")
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.email);
 String[] toArr = {"[e-mail]","[e-mail]"}; 
        m.setTo(toArr);
        m.setFrom("AKASH"); 
        m.setSubject("Your Subject"); 
        m.setBody("Your Message body");

        try {
            boolean i= m.send();
            if(i==true){
                Toast.makeText(getApplicationContext(),"Email was sent successfully ",2000).show();

            }
            else
            {
                Toast.makeText(getApplicationContext(),"Email was not sent successfully ",2000).show();

            }

        } catch (Exception e2) {
            // TODO Auto-generated catch block
            e2.printStackTrace();
        }

}
}
