Sending mail from java

Question

What is the easiest way to send and receive mails in java.

Answer 1

try {
Properties props = new Properties();
props.put("mail.smtp.host", "mail.server.com");
props.put("mail.smtp.auth","true");
props.put("mail.smtp.user", "[e-mail]");
props.put("mail.smtp.port", "25");
props.put("mail.debug", "true");

Session session = Session.getDefaultInstance(props);

MimeMessage msg = new MimeMessage(session);

msg.setFrom(new InternetAddress("[e-mail]"));

InternetAddress addressTo = null;
addressTo = new InternetAddress("[e-mail]");
msg.setRecipient(javax.mail.Message.RecipientType.TO, addressTo);

msg.setSubject("My Subject");
msg.setContent("My Message", "text/html; charset=iso-8859-9");

Transport t = session.getTransport("smtp");   
t.connect("[e-mail]", "password");
t.sendMessage(msg, msg.getAllRecipients());
t.close();
} catch(Exception exc) {
  exc.printStackTrace();
}

Answer 2

JavaMail is the traditional answer for sending email (as everyone's pointing out).

As you also want to receive mail, however, you should check out Apache James. It's a modular mail server and heavily configurable. It'll talk POP and IMAP, supports custom plugins and can be embedded in your application (if you so wish).

Check this package out. From the link, here's a code sample:

Properties props = new Properties();
props.put("mail.smtp.host", "my-mail-server");
props.put("mail.from", "[e-mail]");
Session session = Session.getInstance(props, null);

try {
    MimeMessage msg = new MimeMessage(session);
    msg.setFrom();
    msg.setRecipients(Message.RecipientType.TO,
                      "[e-mail]");
    msg.setSubject("JavaMail hello world example");
    msg.setSentDate(new Date());
    msg.setText("Hello, world!\n");
    Transport.send(msg);
} catch (MessagingException mex) {
    System.out.println("send failed, exception: " + mex);
}
