Android 使用javamail傳送郵件
專案需要activation.jar,additionnal.jar,mail.jar 下載三個包
編寫郵件傳送步驟：
- 設定伺服器
- 新增郵箱認證
- 設定認證的Session（重要）
- 根據Session獲取郵件物件(MimeMessage)
- 郵件物件的填充（發件人，收件人，標題，內容和附件）
- 郵件的傳送
編寫程式碼如下：
/*傳送郵件的主要程式碼*/ Properties properties = System.getProperties();//獲取系統屬性 properties.put("mail.smtp.host", "smtp.sina.com");//郵箱對於的伺服器 properties.put("mail.smtp.auth", "true");//設定需要使用者名稱和密碼（客戶端授權碼）認證 Session session = Session.getDefaultInstance(properties,new Authenticator(){//認證Session @Override protected PasswordAuthentication getPasswordAuthentication() { return new PasswordAuthentication(userName, password); //發件人郵件使用者名稱、密碼（客戶端授權碼） } }); session.setDebug(true);//Log輸出，方便除錯 MimeMessage message = new MimeMessage(session);//根據Session獲得郵件物件 try { message.setFrom(new InternetAddress(from_email));//添加發件人 message.addRecipient(Message.RecipientType.TO,new InternetAddress(to_email));//新增收件人 message.setSubject("This is the Subject Line!");//標題 Multipart multipart = new MimeMultipart();//可以帶附件訊息物件 BodyPart messageBodyPart = new MimeBodyPart();//文字訊息部分 messageBodyPart.setText("This is message body"); multipart.addBodyPart(messageBodyPart);//新增文字訊息 for (int i=0;i<fileList.size();i++) {//fileList是List<File> BodyPart fileBodyPart = new MimeBodyPart();//附件部分 DataSource source = new FileDataSource(fileList.get(i)); fileBodyPart.setDataHandler(new DataHandler(source)); fileBodyPart.setFileName(fileList.get(i).getName()); multipart.addBodyPart(fileBodyPart);//新增附件訊息 } message.setContent(multipart);//填充訊息 //解決javax.activation.UnsupportedDataTypeException: no object DCH for MIME type multipart/mixed; MailcapCommandMap mc = (MailcapCommandMap) CommandMap.getDefaultCommandMap(); mc.addMailcap("text/html;; x-java-content-handler=com.sun.mail.handlers.text_html"); mc.addMailcap("text/xml;; x-java-content-handler=com.sun.mail.handlers.text_xml"); mc.addMailcap("text/plain;; x-java-content-handler=com.sun.mail.handlers.text_plain"); mc.addMailcap("multipart/*;; x-java-content-handler=com.sun.mail.handlers.multipart_mixed"); mc.addMailcap("message/rfc822;; x-java-content-handler=com.sun.mail.handlers.message_rfc822"); CommandMap.setDefaultCommandMap(mc); Thread.currentThread().setContextClassLoader(getClass().getClassLoader()); Transport transport = session.getTransport("smtp"); transport.addTransportListener(new TransportAdapter() {//郵件傳送監聽 @Override public void messageDelivered(TransportEvent e) { super.messageDelivered(e); Log.e("監聽郵件傳送","郵件傳送成功...."); } @Override public void messageNotDelivered(TransportEvent e) { super.messageNotDelivered(e); Log.e("監聽郵件傳送","郵件傳送失敗...."); } @Override public void messagePartiallyDelivered(TransportEvent e) { super.messagePartiallyDelivered(e); Log.e("監聽郵件傳送","郵件傳送部分成功...."); } }); transport.connect(); transport.sendMessage(message, message.getAllRecipients()); transport.close(); } catch (MessagingException e) { e.printStackTrace(); }
測試郵箱：163郵箱、qq郵箱、139郵箱、sohu郵箱、126郵箱、tom郵箱、新浪郵箱、outlook郵箱、aliyun郵箱
- aliyun郵箱傳送郵件都被系統退回（個人無解）
- 163郵箱傳送郵件基本都有遇到com.sun.mail.smtp.SMTPSendFailedException: 554 DT:SPM 問題（個人無解）
- Log輸出提示傳送成功，但是收件人郵箱沒有收到（郵件被退回或收件人郵箱不存在）
- 傳送成功，收件箱看不到（在垃圾箱）
- outlook郵箱註冊但未驗證發郵件會被系統攔截
163郵箱，遇到問題：
1、com.sun.mail.smtp.SMTPSenderFailedException: 550 User has no permission
//設定客戶端授權碼並開啟POP3/SMTP/IMAP2、com.sun.mail.smtp.SMTPSendFailedException: 553 authentication is required
//新增
properties.put("mail.smtp.auth", "true");（設定完沒有新增使用者名稱和授權碼會遇到下面一個問題）3、javax.mail.AuthenticationFailedException: failed to connect, no password specified?
//設定 session = Session.getInstance(email.properties,new Authenticator(){ @Override protected PasswordAuthentication getPasswordAuthentication() { //發件人郵件使用者名稱、授權碼 return new PasswordAuthentication(userName, password); } });
4、javax.activation.UnsupportedDataTypeException: no object DCH for MIME type multipart/mixed
//傳送Multipart訊息前新增
MailcapCommandMap mc = (MailcapCommandMap) CommandMap.getDefaultCommandMap();
mc.addMailcap("text/html;; x-java-content-handler=com.sun.mail.handlers.text_html");
mc.addMailcap("text/xml;; x-java-content-handler=com.sun.mail.handlers.text_xml");
mc.addMailcap("text/plain;; x-java-content-handler=com.sun.mail.handlers.text_plain");
mc.addMailcap("multipart/*;; x-java-content-handler=com.sun.mail.handlers.multipart_mixed");
mc.addMailcap("message/rfc822;; x-java-content-handler=com.sun.mail.handlers.message_rfc822");
CommandMap.setDefaultCommandMap(mc);
Thread.currentThread().setContextClassLoader(getClass().getClassLoader());
Transport.send(message);//傳送訊息5、java.io.IOException: javax.mail.MessagingException: Empty multipart: multipart/mixed
//新增內容或附件
multipart.addBodyPart(new MimeBodyPart());//自己設定MimeBodyPart//•554 DT:SPM 傳送的郵件內容包含了未被許可的資訊，或被系統識別為垃圾郵件。請檢查是否有使用者傳送病毒或者垃圾郵件；
//呵呵
//我試了2個qq郵箱，都是這情況。換了個139郵箱，就傳送成功了。之後再試其他郵箱（包括139）一直被系統識別為垃圾郵件qq郵箱，遇到問題（已經設定客戶端授權碼並開啟POP3/SMTP/IMAP）
1、com.sun.mail.smtp.SMTPSendFailedException: 503 Error: need EHLO and AUTH first !
//新增
properties.put("mail.smtp.auth", "true");
//設定
session = Session.getInstance(email.properties,new Authenticator(){
@Override
protected PasswordAuthentication getPasswordAuthentication() {
//發件人郵件使用者名稱、授權碼
return new PasswordAuthentication(userName, password);
}
});2、javax.mail.NoSuchProviderException: Invalid protocol: null（設定addTransportListener監聽郵件傳送狀況時出現）
//設定
Transport transport = session.getTransport("smtp");搜狐郵箱，遇到問題

//發件人郵箱未驗證，被認為垃圾郵件傳送者（驗證後就可以了）
