greenmail server not receiving the mail

• 
  

  My Unit Test for class for email through Greenmail

  
  

  @Before public void testSmtpInit() { greenMail = new GreenMail(ServerSetupTest.SMTP); greenMail.start(); messageTemplateService = mock(MessageTemplateService.class); emailProperties = mock(EmailProperties.class); emailService.setEmailProperties(emailProperties); }

  
  

  @Test public void testEmail() throws InterruptedException, IOException {

  
  

  
  String to = "abc@localhost.com";
  String from = "test@localhost.com";
  String subject = "subject";
  String contentType = "text/html";
  String user = "test@localhost.com";
  String login="test@localhost.com";
  String password = "12345";
  String body = "msgbody";
  greenMail.setUser(login,user, password);
  Properties props = System.getProperties();
  props.put("mail.smtp.host", "smtp.gmail.com");
  props.put("mail.smtp.auth", "true");
  props.put("mail.smtp.port", ServerSetupTest.SMTP.getPort());
  Session session = Session.getInstance(props, null);
  Message msg = new MimeMessage(session);
  
  try {
      msg.setFrom(new InternetAddress(to));
      msg.setRecipients(Message.RecipientType.TO, InternetAddress.parse(to));
      msg.setSubject(subject);
      msg.setText(body);
      msg.setSentDate(new Date());
      Transport t = session.getTransport("smtp");
      t.connect(user, password);
      t.sendMessage(msg, msg.getAllRecipients());
      t.close();
  } catch (MessagingException e) {
      // TODO Auto-generated catch block
      e.printStackTrace();
  }
  
  MimeMessage[] messages = greenMail.getReceivedMessages();
  assertNotNull(messages);
  assertEquals(1, messages.length);
  MimeMessage m = messages[0];
  try {
      assertEquals(subject, m.getSubject());
      assertTrue(String.valueOf(m.getContent()).contains(body));
      assertEquals(to, m.getFrom()[0].toString());//
  } catch (MessagingException e) {
      // TODO Auto-generated catch block
      e.printStackTrace();
  }
  
  

  
  

  }
