如何使用JavaMail将Return-Path设置为发件人地址以外的电子邮件地址？

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

// 发件人和收件人的电子邮件地址和密码
String from = "your_email@example.com";
String password = "your_email_password";
String to = "recipient@example.com";

// 设置邮件服务器的属性
Properties props = new Properties();
props.put("mail.smtp.host", "smtp.example.com");
props.put("mail.smtp.port", "587");
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.starttls.enable", "true");

Authenticator auth = new Authenticator() {
    protected PasswordAuthentication getPasswordAuthentication() {
        return new PasswordAuthentication(from, password);
    }
};

Session session = Session.getInstance(props, auth);

MimeMessage msg = new MimeMessage(session);
msg.setFrom(new InternetAddress(from));
msg.addRecipient(Message.RecipientType.TO, new InternetAddress(to));
msg.setSubject("JavaMail测试邮件");
msg.setText("这是一个使用JavaMail发送的测试邮件。");

// 设置Return-Path为发件人地址以外的电子邮件地址
msg.setHeader("Return-Path", "return_path@example.com");

Transport.send(msg);
