Использую JavaMail API для отправки почты.
Делаю вот так:
public void sendMail() {
try {
String SMTP_AUTH_USER = "test@gmail.com";
String SMTP_AUTH_PWD = "test123456";
Properties props = new Properties();
/*props.put("mail.transport.protocol", "smtps");
props.put("mail.smtp.ssl.enable", "true");*/
props.put("mail.smtp.host", "smtp.gmail.com");
props.put("mail.smtp.auth", "true");
props.put("mail.debug", "true");
props.put("mail.smtp.port", 587);
props.put("mail.smtp.socketFactory.port", 587);
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.transport.protocol", "smtp");
props.put("mail.smtp.socketFactory.class",
"javax.net.ssl.SSLSocketFactory");
Session session = Session.getDefaultInstance(props);
session.setDebug(true);
Transport transport = session.getTransport();
transport.connect("smtp.gmail.com", 547, SMTP_AUTH_USER, SMTP_AUTH_PWD);
MimeMessage message = new MimeMessage(session);
message.setSubject("Test Mail from Java Program");
message.setText("You can send mail from Java program by using mail API, but you need" +
"couple of more JAR files e.g. smtp.jar and activation.jar");
InternetAddress address = new InternetAddress("test@gmail.com");
message.addRecipient(Message.RecipientType.TO, address);
message.setSentDate(new Date());
transport.sendMessage(message, message.getRecipients(Message.RecipientType.TO));
} catch (MessagingException ex) {
ex.printStackTrace();
}
}
Получаю вот такое:

Вот здесь есть рабочий пример отправки почты при помощи JavaMail API.
С TLS-шифрованием:
public class SendMailTLS {
public static void main(String[] args) {
final String username = "username@gmail.com";
final String password = "password";
Properties props = new Properties();
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.host", "smtp.gmail.com");
props.put("mail.smtp.port", "587");
Session session = Session.getInstance(props,
new javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(username, password);
}
});
try {
Message message = new MimeMessage(session);
message.setFrom(new InternetAddress("from-email@gmail.com"));
message.setRecipients(Message.RecipientType.TO,
InternetAddress.parse("to-email@gmail.com"));
message.setSubject("Testing Subject");
message.setText("Dear Mail Crawler,"
+ "\n\n No spam to my email, please!");
Transport.send(message);
System.out.println("Done");
} catch (MessagingException e) {
throw new RuntimeException(e);
}
}
}
С SSL-шифрованием:
public class SendMailSSL {
public static void main(String[] args) {
Properties props = new Properties();
props.put("mail.smtp.host", "smtp.gmail.com");
props.put("mail.smtp.socketFactory.port", "465");
props.put("mail.smtp.socketFactory.class",
"javax.net.ssl.SSLSocketFactory");
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.port", "465");
Session session = Session.getDefaultInstance(props,
new javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication("username","password");
}
});
try {
Message message = new MimeMessage(session);
message.setFrom(new InternetAddress("from@no-spam.com"));
message.setRecipients(Message.RecipientType.TO,
InternetAddress.parse("to@no-spam.com"));
message.setSubject("Testing Subject");
message.setText("Dear Mail Crawler," +
"\n\n No spam to my email, please!");
Transport.send(message);
System.out.println("Done");
} catch (MessagingException e) {
throw new RuntimeException(e);
}
}
}
