You need to authenticate to your SMTP server. The package javadocs for the com.sun.mail.smtp package describe several methods to do this. The easiest is often to replace the call Transport.send(msg); with
String protocol = “smtp”;
props.put(“mail.” + protocol + “.auth”, “true”);
…
Transport t = session.getTransport(protocol);
try {
t.connect(username, password);
t.sendMessage(msg, msg.getAllRecipients());
} finally {
t.close();
}
You’ll have to supply the appropriate username and password needed by your mail server. Note that you can change the protocol to “smtps” to make a secure connection over SSL.
