Question

我尝试运行一个小程序，向我的帐户发送通用电子邮件但我得到一个例外：

  javax.mail.SendFailedException: Invalid Addresses;
  nested exception is:
    com.sun.mail.smtp.SMTPAddressFailedException: 553 We do not relay non-local mail, sorry.

    at com.sun.mail.smtp.SMTPTransport.rcptTo(SMTPTransport.java:1873)

这是我的代码

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

public class SendEmail
{
   public static void main(String [] args)
   {    
      // Recipient's email ID needs to be mentioned.
      String to = "Basti-V@web.de";

      // Sender's email ID needs to be mentioned
      String from = "Basti-V@web.de";

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

      // Get system properties
      Properties properties = System.getProperties();

      // 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("This is actual message");

         // Send message
         Transport.send(message);
         System.out.println("Sent message successfully....");
      }catch (MessagingException mex) {
         mex.printStackTrace();
      }
   }
}

我使用XAMPP控制面板运行Mercury Server。港口是25,79,105,106,110,143和2224.我是新手，所以也许有人可以把我推向正确的方向。

Answer 1

您必须取消选中“不允许SMTP中继非本地邮件”选项。

请参阅链接：uncheck option

Answer 2

请检查以下两件事。 1）。主机邮件服务器正在运行的地方。如果它在本地计算机上运行，则将主机地址设置为0.0.0.0

2.如果是外部邮件服务器，请检查用户名，密码，主机等邮件凭据。

我认为553是服务器的“拒绝错误”，这意味着您没有提供正确的凭据。
