below is the code im using to send email
Properties props = new Properties();
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.starttls.required", "true");
props.put("mail.smtp.sasl.enable", "true");
props.put("mail.smtp.host", "smtp.gmail.com");
props.put("mail.smtp.port", "587");
props.put("mail.imaps.sasl.mechanisms", "XOAUTH2");
props.put(OAuth2SaslClientFactory.OAUTH_TOKEN_PROP, oauthToken);
//props.put("mail.smtp.password", "");
// props.put("mail.smtp.auth", "true");
Session session = Session.getInstance(props);
session.setDebug(debug);
final URLName unusedUrlName = null;
SMTPTransport transport = new SMTPTransport(session, unusedUrlName);
// If the password is non-null, SMTP tries to do AUTH LOGIN.
final String emptyPassword = null;
transport.connect(host, port, userEmail, emptyPassword);
byte[] response = String.format("user=%s\1auth=Bearer %s\1\1",
userEmail, oauthToken).getBytes();
response = BASE64EncoderStream.encode(response);
transport.issueCommand("AUTH XOAUTH2 " + new String(response), 235);
return new SMTPConnection(transport, session, new String(response));
--------------XXX end of method XXX-----------------
SMTPConnection smtpConnection = XoauthAuthenticator.connectToSmtp("smtp.gmail.com", 587,
user.getEmail(), user.getAccessToken(), null, XoauthAuthenticator.getAnonymousConsumer(),
true);
SMTPMessage smtpMessage = new SMTPMessage(smtpConnection.getSession());
smtpMessage.setFrom(new InternetAddress(user.getEmail()));
smtpMessage.setRecipients(RecipientType.TO, InternetAddress.parse(email));
String subject = message;
smtpMessage.setSubject(subject);
smtpMessage.setText(message);
smtpMessage.setSentDate(new Date());
smtpConnection.getSMTPTransport().simpleCommand("HELO");
boolean isConnected = smtpConnection.getSMTPTransport().isConnected();
smtpConnection.getSMTPTransport().send(smtpMessage, smtpMessage.getAllRecipients());
Your help is greatly appreciated.
Thank you, -bala.
