javamail error while authenticating to SMTP server

[ameyas7]

hi all,

i wrote a simple program as follows.
i am trying to send mail through SMTP server.
i have set the following property to true
props.put("mail.smtp.auth", "true");


Transport transport = session.getTransport("smtp");
transport.connect("localhost", "(e-mail address removed)", "");
transport.sendMessage(message,addr);
transport.close();




javax.mail.AuthenticationFailedException
at javax.mail.Service.connect(Service.java:264)
at javax.mail.Service.connect(Service.java:134)
at sendmail.EMailHandler.send(EMailHandler.java:53)
at sendmail.demo.SendMailDemo.main(SendMailDemo.java:11)

i am not sure which username and password we need to provide while
connecting to the server.

i have installed hMailServer i tried using Administrator password for
server but did not work.
i tried using the from mail a/c user name , password but no luck.

can someone tell me what am i missing here ? which username , password
do we need to give. do we need any specific setting on smtp server ?
any example ?



On setting DEBUG true i get the following trace from the SMTP server.


DEBUG: setDebug: JavaMail version 1.3.2

Transport transport = session.getTransport("smtp");
transport.connect("localhost", "(e-mail address removed)", "");
transport.sendMessage(message,addr);
transport.close();

you need something like this:

Properties props = System.getProperties();
if ( NEED_PASSWORD_TO_SEND )
{
props.setProperty( "mail.smtp.auth", "true" );
}
// Get a Session object
session = Session.getDefaultInstance( props, null );
session.setDebug( DEBUGGING );

Transport transport = session.getTransport( SEND_PROTOCOL );
transport.connect( SEND_HOST,
SEND_PORT,
SEND_LOGIN_ID,
SEND_PASSWORD );

There might also be a way to do it with an Authenticator.

I think you're very close... the properties seem to be correct. You may use this:
Session session = Session.getDefaultInstance(properties, auth);
SMTPTransport transport = (SMTPTransport)session.getTransport("smtp");
transport.connect();

//create your SMTPMessage, "message".
transport.sendMessage(message, message.getAllRecipients());
