如何在回复地址中设置认证用户的邮箱？

import smtplib
from email.mime.text import MIMEText

def send_email(sender_email, receiver_email, subject, message):
    # 设置邮件内容
    msg = MIMEText(message)
    msg['Subject'] = subject
    msg['From'] = sender_email
    msg['To'] = receiver_email

    # 设置回复地址为用户的邮箱
    msg.add_header('Reply-To', sender_email)

    # 发送邮件
    smtp_server = 'your_smtp_server'
    smtp_port = 587
    smtp_username = 'your_smtp_username'
    smtp_password = 'your_smtp_password'

    with smtplib.SMTP(smtp_server, smtp_port) as server:
        server.starttls()
        server.login(smtp_username, smtp_password)
        server.sendmail(sender_email, receiver_email, msg.as_string())

# 调用函数发送邮件
sender_email = 'your_sender_email@example.com'
receiver_email = 'your_receiver_email@example.com'
subject = 'Test Email'
message = 'This is a test email.'
send_email(sender_email, receiver_email, subject, message)
