问题:

I can authenticated to SMTP by following the google example.

But the problem now is I can't send out the mail. I am getting the following error whenever I try to send out mail.

com.sun.mail.smtp.SMTPSendFailedException: 530-5.5.1 Authentication Required. Learn more at
530 5.5.1 http://support.google.com/mail/bin/answer.py?answer=14257 f5sm19578172pav.22

    at com.sun.mail.smtp.SMTPTransport.issueSendCommand(SMTPTransport.java:2114)
    at com.sun.mail.smtp.SMTPTransport.mailFrom(SMTPTransport.java:1618)
    at com.sun.mail.smtp.SMTPTransport.sendMessage(SMTPTransport.java:1119)
    at javax.mail.Transport.send0(Transport.java:195)
    at javax.mail.Transport.send(Transport.java:124)

First I am getting can't connect to local host , thus I added a few lines of code to propery of session like below to OAuth2Authenticator class , still authenicated successfully. But can't send out the mail.

props.put("mail.smtp.host", "smtp.gmail.com");
props.put("mail.smtp.port", "587");

I am using the same session object and SMTP transport object which will be returned from OAuth2Authenticator class when I first authenticated successfully.

            Message message = new MimeMessage(session);


        message.setFrom(new InternetAddress(msg.getFrom()));
        message.setRecipients(Message.RecipientType.TO,
            InternetAddress.parse(msg.getTo()));
        message.setSubject(msg.getSubject());
        message.setText(msg.getBody());

        transport.send(message);

Edited: I now called AUTH command explicitly like that .

 byte[] response = String.format("user=%s\1auth=Bearer %s\1\1",
                    emailAddress, accessToken.getToken()).getBytes();
            response = BASE64EncoderStream.encode(response);
            System.out.println("token check : " + new String(response));

            transport.issueCommand("AUTH XOAUTH2 " + new String(response), 235);

but the response still the same.

回答1:

Sorry people, answer is here: Javamail api in android using XOauth I tested, it works.

"SMS style login" failure - Secure accounts with 2 step login (via phone SMS) reject sending email via SMTP (both RAW password & OAuth style, fail with a Authentication error). They will let you create the OAuth token but will not send email.

回答2:

You just need to authenticate. Follow this example, it also uses gmail: http://www.mkyong.com/java/javamail-api-sending-email-via-gmail-smtp-example/

回答3:

This is an old thread but it took me a very long time to figure this out after going through numerous forums (and none of them had the right answer) so I'll post it if it helps someone. Many of the answers above suggest using password which is incorrect

If you are using the latest google apis with OAuth2 and also using the sample code @ http://code.google.com/p/google-mail-oauth2-tools/downloads/detail?name=oauth2-java-sample-20120904.zip&can=2&q=

and are getting the exception com.sun.mail.smtp.SMTPSendFailedException: 530-5.5.1 Authentication Required. Learn more at 530 5.5.1 http://support.google.com/mail/bin/answer.py?answer=14257 vo6sm6969236pbc.8 - gsmtp

Here are the steps to fix the problem

Run python oauth2.py exactly as the instruction suggest in the zip download. The OAuth2 Argument is the oauthtoken you must use in the code.

After running the OAuth2Authenticator.connectToSmtp("smtp.googlemail.com", 587, email, oauthToken, true) method to get the SMTPTransport. To send the message:

  //create the message
  //Note that you do need to get the same session object that gets created within the connectToSmtp method.
  MimeMessage message = new MimeMessage(session);
  message.setFrom(new InternetAddress("from@gmail.com"));
  message.addRecipient(Message.RecipientType.TO, new InternetAddress("to@gmail.com"));
  message.setSubject("This is the Subject Line!");
  message.setText("This is actual message");

  //this was the magic line that is needed - for authentication
  transport.issueCommand("AUTH XOAUTH2 " + oauthToken, 235);

  //send the message
  transport.sendMessage(message, message.getAllRecipients());

回答4:

I think so it is asking for authentication of your username.

session=Session.getInstance(props,
         new javax.mail.Authenticator() {
            protected PasswordAuthentication getPasswordAuthentication() {
                return new PasswordAuthentication(fromUsername, password);
            }
          });

And then use above session in your code.

I haven't use the code specified in the google link u mentioned but i use java mail api to send email from my gmail account.Use above code for authentication

回答5:

try adding these to your props config..

  props.put("mail.smtp.auth", true);
  props.put("mail.smtp.starttls.enable", true);

add your password and the line u missed because of which u r getting authentication required exception is :::

props.put("mail.smtp.auth","true");

in your connectToSmtp(.... , ...); method

AND RESPONSE YOU GET IS ::
