我用java编写了一个小的电子邮件发送程序,它有
from
to
reply to
地址,当客户端试图回复邮件时,它应该能够回复
reply to
地址。 目前不工作,我的代码如下:

// File Name SendEmail.java

import java.util.*;
import javax.mail.*;
import javax.mail.internet.*;
import javax.activation.*;

public class SendEmail
{
   public static void main(String [] args)
   {

      // Recipient's email ID needs to be mentioned.
      String to = "xyz@gmail.com";

      // Sender's email ID needs to be mentioned
      String from = "abcd@gmail.com";

      // Assuming you are sending email from localhost
      String host = "localhost";

      // Get system properties
      Properties properties = System.getProperties();
    properties.put("mail.smtp.from", "mnop@gmail.com");

      // Setup mail server
      properties.setProperty("mail.smtp.host", host);

      // Get the default Session object.
      Session session = Session.getDefaultInstance(properties);

      try{
         // Create a default MimeMessage object.
         MimeMessage message = new MimeMessage(session);

         // Set From: header field of the header.
         message.setFrom(new InternetAddress(from));

         // Set To: header field of the header.
         message.addRecipient(Message.RecipientType.TO,
                                  new InternetAddress(to));

         // Set Subject: header field
         message.setSubject("This is the Subject Line!");

         // Now set the actual message
         message.setText("New Message goes here");

         // Send message
         Transport.send(message);
         System.out.println("Sent message successfully....");
      }catch (MessagingException mex) {
         mex.printStackTrace();
      }
   }
}
我用的是真正的gmail账户。有人能帮忙吗

请注意:

  • “from”与“reply to”不同
  • 根据,发件人地址的属性为“mail.from”
  • 的文档指定,仅当没有现有默认实例时,才会创建新实例,并且仅在创建新实例时使用属性。此外,默认实例是一个全局值,将被重复使用,因此除非您希望在所有电子邮件中使用相同的“发件人”地址,否则您需要创建新会话(使用getInstance()
试试:

MimeMessage message = new MimeMessage(session);
message.setReplyTo(new javax.mail.Address[]
{
    new javax.mail.internet.InternetAddress("mnop@gmail.com")
});

您的代码似乎没有试图设置回复地址。设置
mail.smtp.from
..怎么样。。。?
