java - Gmail 中的 SMTPSendFailedException 530，SMTP 失败而 IMAP 工作

Question

我有一个示例 gmail 客户端类。在该类(class)中，我初始化了 IMAPS 和 SMTPS session 。有一段时间它工作正常。但是现在 Gmail 抛出 SMTO 发送失败异常。

这是我如何通过 javamail 连接到 Gmail..

//String smtpHost = "imap.gmail.com";
//String imapHost = "smtp.gmail.com";
//String userName = "XXXXXX@gmail.com";
//String userPass = "PASSWORD";
//Properties props = new Properties();


public DirectMailBox(String smtpHost, String imapHost, String userName,
        String userPass, Properties props) throws MessagingException {
    super();
    this.imapHost = imapHost;
    this.smtpHost = smtpHost;
    this.userName = userName;
    this.userPass = userPass;
    this.props = props;

    session = Session.getDefaultInstance(props);
    session.setDebug(true);
    imapsStore = session.getStore("imaps");
    imapsStore.connect(imapHost, userName, userPass);

    smtpsTransport = session.getTransport("smtps");
    smtpsTransport.connect(smtpHost, userName, userPass);
    smtpsTransport.addTransportListener(this);
}

这是我如何调用 sendmail..

public void sendMail(MimeMessage newMessage) throws MessagingException {
    smtpsTransport.sendMessage(newMessage, newMessage.getAllRecipients());
}

按照此 URL 上的说明进行操作，但没有解决方案。 http://support.google.com/mail/bin/answer.py?answer=14257

终于解决了这个问题..!!使用以下方法。

http://mlusincuba.wordpress.com/2012/03/03/java-mail-gmail-smtp-client/

package com.mycompany.employee.utils;

import java.io.UnsupportedEncodingException;
import java.util.Properties;
import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;

/**

public class GMail {

    public static void sendMail(String senderEmail, String recipientEmail, String subject, String message) throws MessagingException, UnsupportedEncodingException {

        // SSL // I USED THIS METHOD            
        Properties propsSSL = new Properties();

        // EVEN IF YOU SKIP THESE TWO PROP IT WOULD WORK
        propsSSL.put("mail.transport.protocol", "smtps");
        propsSSL.put("mail.smtps.host", "smtp.gmail.com");

        // THIS IS THE MOST IMPORTANT PROP --> "mail.smtps.auth"
        propsSSL.put("mail.smtps.auth", "true");

        Session sessionSSL = Session.getInstance(propsSSL);
        sessionSSL.setDebug(true);

        Message messageSSL = new MimeMessage(sessionSSL);
        messageSSL.setFrom(new InternetAddress("yourgmail@gmail.com", "Mlungisi Sincuba"));
        messageSSL.setRecipients(Message.RecipientType.TO, InternetAddress.parse("yourgmail@gmail.com")); // real recipient
        messageSSL.setSubject("Test mail using SSL");
        messageSSL.setText("This is test email sent to Your account using SSL.");

        Transport transportSSL = sessionSSL.getTransport();
        // EVEN IF YOU SKIP PORT NUMBER , IT WOULD WORK
        transportSSL.connect("smtp.gmail.com", 465, "yourgmail@gmail.com", "yourpassword"); // account used
        transportSSL.sendMessage(messageSSL, messageSSL.getAllRecipients());
        transportSSL.close();

        System.out.println("SSL done.");
    }

    public static void main(String[] args) throws MessagingException, UnsupportedEncodingException {
        System.out.println("Hello World!");
        sendMail(null, null, null, null);
    }
