Hi All,

Great to have this discussion group which is helping to clear the
issues.

Thanks in advance to all.

I am having strange exception when trying to send email through java. I
am using my mail server hostname to connect it. My mail server is SMTP
server.
When I tried to ping the IP Address it is fine. I tried to execute the
same in another machine. The result is same.

The exception I am getting is this way.

javax.mail.MessagingException: Could not connect to SMTP host:
<hostname>, port: 25;
 nested exception is:
    java.net.SocketException: Software caused connection abort: connect
    at com.sun.mail.smtp.SMTPTransport.openServer(SMTPTransport.java:1008)
    at
com.sun.mail.smtp.SMTPTransport.protocolConnect(SMTPTransport.java:197)
    at javax.mail.Service.connect(Service.java:233)
    at javax.mail.Service.connect(Service.java:134)
    at javax.mail.Service.connect(Service.java:86)
    at com.sun.mail.smtp.SMTPTransport.connect(SMTPTransport.java:104)

I googled about this issue, but I couldn't get the exact idea and
solution to overcome this exception. My code looks like this.

package sendingmail;

import java.util.Properties;
import javax.mail.Session;
import javax.mail.Message;
import javax.mail.Transport;
import javax.mail.internet.MimeMessage;
import javax.mail.internet.InternetAddress;
import java.util.Date;
import javax.mail.MessagingException;
import javax.mail.internet.MimeBodyPart;
import javax.mail.Multipart;
import javax.mail.internet.MimeMultipart;
import javax.activation.FileDataSource;
import javax.activation.DataHandler;

public class SendingMailMultipart
{
   private static String HostName = "<HostName>";
   private static String FromAddress = "fromname@gmail.com";
   private static String ToAddress = "toname@yahoo.co.in";

   public SendingMailMultipart()
   {
       SendEmail();
   }

   protected void SendEmail()
   {
      Properties props = new Properties();
      //props.put("mail.transport.protocol", "smtp");
      props.put("mail.smtp.host",HostName);
      //props.put("mail.debug","true");

      Session session  = Session.getInstance(props);
      try
      {
          Transport trans = session.getTransport("smtp");
          trans.connect();

          Message msg = new MimeMessage(session);
          msg.setFrom(new InternetAddress(FromAddress));
          InternetAddress[] Address = {new
InternetAddress(ToAddress)};
          msg.setRecipients(Message.RecipientType.TO,Address);

msg.setRecipients(Message.RecipientType.CC,InternetAddress.parse(ToAddress,true));

msg.setRecipients(Message.RecipientType.BCC,InternetAddress.parse(ToAddress,false));
          msg.setSubject("Test Mail Using Java Mail Multipart");
          msg.setSentDate(new Date());

          setContentOfMsg(msg);
          msg.saveChanges();
          trans.sendMessage(msg,Address);

          setMultiPartContent(msg);
          msg.saveChanges();
          trans.sendMessage(msg,Address);

          setFileAttachedToMail(msg,"D:\\Kishore\\NOTEPADS\\My
Details.txt");
          msg.saveChanges();
          trans.sendMessage(msg,Address);
      }
      catch(Exception ex)
      {
          ex.printStackTrace();
      }
   }

   private void setContentOfMsg(Message msg)
   {
       try
       {
         String Content = "Hi This Is sending you mail through Java.";
         msg.setText(Content);
         msg.setContent(Content,"text/plain");
       }
       catch(MessagingException ex)
       {
           ex.printStackTrace();
       }
   }

   private void setMultiPartContent(Message msg)
   {
       try
       {
           MimeBodyPart MBP1 = new MimeBodyPart();
           MBP1.setText("Hai Hai Hai Hai Hai Hai Hai Hai Hai Hai Hai
Hai Hai Hai Hai Hai " +
                       "This is part one of a test multipart e-mail");

           MimeBodyPart MBP2 = new MimeBodyPart();
           MBP2.setText("Second Part","us-ascii");

           Multipart MP = new MimeMultipart();
           MP.addBodyPart(MBP1);
           MP.addBodyPart(MBP2);

           msg.setContent(MP);
       }
       catch(MessagingException ex)
       {
           ex.printStackTrace();
       }
   }

   private void setFileAttachedToMail(Message msg,String FileName)
   {
       try
       {
           MimeBodyPart MBP1 = new MimeBodyPart();
           MBP1.setText("This is the first part in FileAttachment
MimeBodyPart1");

           MimeBodyPart MBP2 = new MimeBodyPart();
           FileDataSource FDS = new FileDataSource(FileName);
           MBP2.setDataHandler(new DataHandler(FDS));
           MBP2.setFileName(FDS.getName());

           Multipart MP = new MimeMultipart();
           MP.addBodyPart(MBP1);
           MP.addBodyPart(MBP2);

           msg.setContent(MP);
       }
       catch(MessagingException ex)
       {
           ex.printStackTrace();
       }
   }

   public static void main(String[] args)
   {
       SendingMailMultipart sendingmailmultipart = new
SendingMailMultipart();
   }
}

Can any one kindly suggest what is that going wrong in this snippet
code, if you have come across the same scenario. Please help out in
this regards.

regards,
kishore.
