javamail, Connection timed out

[OmerHalit]

hi,

I am trying to send email, I think something blocks it.

I keep getting this error :

Exception in thread "main" javax.mail.MessagingException: Could not connect to SMTP host: smtp.live.com, port: 25;
  nested exception is:
        java.net.ConnectException: Connection timed out: connect
        at com.sun.mail.smtp.SMTPTransport.openServer(SMTPTransport.java:1706)
...

it seems like it is a firewall problem, but i turned off my antivirus and firewall. when I try to connect from cmd (telnet smtp.live.com 25) it cant connect either. I tried to unblock port 25 but I couldnt make it either, I put exception to windows firewall(it is already turned off) it still cant connect thru that port.

but when i type telnet smtp.live.com 587 to command promt, it connects..

how do I overcome this problem? or how do I connect over port 587 in java?

here is my code:

public class SendMailUsingAuthentication
{

  private static final String SMTP_HOST_NAME = "smtp.live.com";
  private static final String SMTP_AUTH_USER = "asd@hotmail.com";
  private static final String SMTP_AUTH_PWD  = "asdasd";

  private static final String emailMsgTxt      = "msg text";
  private static final String emailSubjectTxt  = "subject txt";
  private static final String emailFromAddress = "asd@yahoo.com";

  // Add List of Email address to who email needs to be sent to
  private static final String[] emailList = {"asd@hotmail.com", "qwe@hotmail.com"};

  public static void main(String args[]) throws Exception
  {
    SendMailUsingAuthentication smtpMailSender = new SendMailUsingAuthentication();
    smtpMailSender.postMail( emailList, emailSubjectTxt, emailMsgTxt, emailFromAddress);
    System.out.println("Sucessfully Sent mail to All Users");
  }

  public void postMail( String recipients[ ], String subject,
                            String message , String from) throws MessagingException
  {
    boolean debug = false;

     //Set the host smtp address
     Properties props = new Properties();
     props.put("mail.smtp.host", SMTP_HOST_NAME);
     props.put("mail.smtp.auth", "true");
     
    Authenticator auth = new SMTPAuthenticator();
    Session session = Session.getDefaultInstance(props, auth);

    session.setDebug(debug);

    // create a message
    Message msg = new MimeMessage(session);

    // set the from and to address
    InternetAddress addressFrom = new InternetAddress(from);
    msg.setFrom(addressFrom);

    InternetAddress[] addressTo = new InternetAddress[recipients.length];
    for (int i = 0; i < recipients.length; i++)
    {
        addressTo[i] = new InternetAddress(recipients[i]);
    }
    msg.setRecipients(Message.RecipientType.TO, addressTo);


    // Setting the Subject and Content Type
    msg.setSubject(subject);
    msg.setContent(message, "text/plain");
    Transport.send(msg);
 }


/**
* SimpleAuthenticator is used to do simple authentication
* when the SMTP server requires it.
*/
private class SMTPAuthenticator extends javax.mail.Authenticator
{

    public PasswordAuthentication getPasswordAuthentication()
    {
        String username = SMTP_AUTH_USER;
        String password = SMTP_AUTH_PWD;
        return new PasswordAuthentication(username, password);
    }
}

}

thanks..

hi,

I am trying to send email, I think something blocks it.

I keep getting this error :
[CODE]Exception in thread "main" javax.mail.MessagingException: Could not connect to SMTP host: smtp.live.com, port: 25;
nested exception is:
java.net.ConnectException: Connection timed out: connect
at com.sun.mail.smtp.SMTPTransport.openServer(SMTPTra nsport.java:1706)

Changing the port to use is easy:

String port= "587";
...
Properties props = System.getProperties();
props.put("mail.smtp.port", port);

If you really want to know what's going on between your client and the smtp server, do this:

session.setDebug(true);

kind regards,

Jos

thank you, it worked for that error.. :) this is the another error I got..

Exception in thread "main" com.sun.mail.smtp.SMTPSendFailedException: 530 5.7.0 Must issue a STARTTLS command first

        at SendMailUsingAuthentication.main(SendMailUsingAuthentication.java:61)
Java Result: 1

when i connected to smtp thru command prompt, whatever I type, it used to give me the same error..

i think connecting to the smtp is ok.. but i can't send the mail, is it because i don't use proper command? :confused:

i connected to smtp thru command prompt, when i typed "STARTTLS" and press enter, it says "Send hello first". what does it mean?

thank you again..

[StormyWaters]

I'm sure it didn't say send Hello first, but rather send HELO first right?

There are two things I remember from when I worked with this...

Try adding another property:

props.put("mail.smtp.ehlo","true");

also I remember creating an instance of Transport to send the message, something like this

Transport transport = session.getTransport("smtp");
transport.connect();//You could specify the Server Address, User Name and Password when connecting but I don't think you need it
transport.sendMessage(msg, msg.getAllRecipients());
transport.close();

Hope this helps.

[OmerHalit]

it really says that..

ok, i will try what you said.. give me a while to try..

Thanks..

[OmerHalit]

I tried, it didn't work.. :(

what else could be?

[StormyWaters]

I never tried connecting to a hotmail account. Let me create one and attempt it.

[OmerHalit]

ok, here is the last looking of my code
...
msg.setRecipients(Message.RecipientType.TO, addressTo);
//everything is same until here

//here was changed according to StormyWaters' suggestion

// Setting the Subject and Content Type
msg.setSubject(subject);
msg.setContent(message, "text/plain");
Transport transport = session.getTransport("smtp");
transport.connect();
transport.sendMessage(msg, msg.getAllRecipients());
transport.close();
//Transport.send(msg);

I get no error until this line : transport.sendMessage(msg, msg.getAllRecipients());

means that, i can connect, but i cannot send the mail.. :( any help??

[StormyWaters]

Forgot a property, try adding this

props.put("mail.smtp.starttls.enable","true");

[OmerHalit]

You are great...!!!

Thanks, it worked.. :)

[xumingming]

how to receive hotmail? when I user store to receive the mail,always to remind me Connect failed;

[OmerHalit]

How do you connect? did you compare your code with the one I sent?
