Mail(SMTP)

Hi I have an application that sends mail to few addresses in an interval. I have the sample code as below,

Code:

 Properties prop = System.getProperties();
 prop.setProperty("mail.smtp.host",<SMTP Mail Server Name>);
 Session session = Session.getInstance(props);
 MimeMessage message = new MimeMessage(session);
 message.setFrom(new InternetAddress("[email protected]"));
 message.addRecipient(Message.RecipientType.TO,new InternetAddress("[email protected]"));
 message.setSubject("test");
 message.setText("Test Mail");
 Transport.send(message);

With in my LAN there is no problem, here I given IP address of the system that runs a Mailer daemon as mail sever name. I am getting mails in outlook express in my LAN. But when I give Our SMTP server name that is used in for internet (Provieded by a service provider who manage our site), I am not finding any error or exceptions but, I could not find mails in the mail box.

Hi,

Usually SMTP servers need authentication, you have to provide the username and password to use SMTP server in java mail.
First you've to implement javax.mail.Authenticator class and override getPasswordAuthentication() method which will return PasswordAuthentication object[just use new PasswordAuthentication(smtp_username, smtp_password)].
You've to pass this PasswordAuthentication object to the Session.getInstanace(properties, authentication object) method as second parameter.

Hope thats helpful.
