Android send custom email STARTTLS port 587

Question

I need to send an email using client settings. Access to the host uses STARTTLS security using port 587. To test rode the following code (changed customer data for security):

String host = "zimbra.mydomain.net.br";
        String port = "587";
        String address = "[email protected]";
        String pass = "******";

        Properties props = new Properties();
        props.put("mail.transport.protocol", "smtp");
        props.put("mail.smtp.quitwait", "false");
        props.put("mail.smtp.host", host); 
        props.put("mail.smtp.user", address); 
        props.put("mail.smtp.password", pass); 
        props.put("mail.smtp.port", port); 
        props.put("mail.smtp.ssl.trust", "*");

        Session session = Session.getDefaultInstance(props, null);

        MimeMessage message = new MimeMessage(session);
        message.setFrom(new InternetAddress(address));

        Multipart multiPart=new MimeMultipart();

        InternetAddress toAddress = new InternetAddress("[email protected]"); 
        message.addRecipient(Message.RecipientType.TO, toAddress);

        message.setSubject("Send Auto-Mail"); 
        message.setContent(multiPart); 
        message.setText("Demo For Sending Mail in Android Automatically");

        Transport transport = session.getTransport("smtp");
        transport.connect(host, address, pass);

        transport.sendMessage(message, message.getAllRecipients());
        transport.close();

Exception:

javax.mail.SendFailedException: Invalid Addresses; nested exception is: com.sun.mail.smtp.SMTPAddressFailedException: 554 5.7.1 unknown[000.000.000.00]: Client host rejected: Access denied

Looks like the server is rejecting your request, perhaps based on your IP address, or perhaps based on the sender or recipient addresses. Add session.setDebug(true) and check the debug output for more clues as to why it's failing.

Also, you probably want to change Session.getDefaultInstance to Session.getInstance.
