小弟 程式碼如下 InternetAddress[] address = null ; final String charset="big5"; String mailserver = "mail.gameflier.com.tw"; String From = "[email protected]"; String to = Email; String Subject = "TEST"; String messageText = "TEST"; String name = Friend; final String UserName="Acc"; final String password="password"; boolean sessionDebug = false; try { sun.misc.BASE64Encoder enc = new sun.misc.BASE64Encoder(); // 設定所要用的Mail 伺服器和所使用的傳送協定 java.util.Properties props = System.getProperties(); props.put("mail.host",mailserver); props.put("mail.transport.protocol","smtp"); Authenticator auth = new javax.mail.Authenticator() { protected PasswordAuthentication getPasswordAuthentication(){ return new PasswordAuthentication(UserName, password); } }; // 產生新的Session 服務 javax.mail.Session mailSession = javax.mail.Session.getDefaultInstance(props,auth); mailSession.setDebug(sessionDebug); Message msg = new MimeMessage(mailSession); // 設定傳送郵件的發信人 InternetAddress ia = new InternetAddress(From); ia.setPersonal(name, "Big5"); msg.setFrom(ia); // 設定傳送郵件至收信人的信箱 address = InternetAddress.parse(to,false); msg.setRecipients(Message.RecipientType.TO, address); // 設定信中的主題 msg.setSubject("=?Big5?B?"+enc.encode(Subject.getBytes())+"?="); // 設定送信的時間 msg.setSentDate(new Date()); // 設定傳送信的MIME Type msg.setText(messageText); // 送信 Transport trans = mailSession.getTransport("smtp"); trans.connect(mailserver , UserName , password); trans.send(msg , msg.getAllRecipients()); trans.close(); System.out.println("郵件己順利傳送"); } catch (MessagingException mex) { mex.printStackTrace(); } 執行後，卻會出現錯誤~ com.sun.mail.smtp.SMTPSendFailedException: 554 5.7.1 Rejected: your IP address is listed in the zen.spamhaus.org RBL 想請問這邊的大大們，這個錯誤訊息是什麼意思~ 或者是說 我的程式哪裡有錯誤~~ 謝謝~ --
