如何以编程方式发送电子邮件并隐藏发件人地址？

import smtplib
from email.mime.text import MIMEText
from email.header import Header

def send_email(sender_email, sender_password, recipient_email, subject, message):
    # 设置邮件内容
    msg = MIMEText(message, 'plain', 'utf-8')
    msg['From'] = Header('Anonymous', 'utf-8')  # 设置发件人名称
    msg['To'] = recipient_email
    msg['Subject'] = Header(subject, 'utf-8')

    # 连接SMTP服务器并发送邮件
    try:
        smtp_server = smtplib.SMTP('smtp.example.com', 587)  # 设置SMTP服务器地址和端口
        smtp_server.starttls()  # 开启TLS加密
        smtp_server.login(sender_email, sender_password)  # 登录SMTP服务器
        smtp_server.sendmail(sender_email, recipient_email, msg.as_string())  # 发送邮件
        smtp_server.quit()  # 断开连接
        print("邮件发送成功！")
    except Exception as e:
        print("邮件发送失败:", str(e))

# 使用示例
sender_email = 'sender@example.com'
sender_password = 'password'
recipient_email = 'recipient@example.com'
subject = '隐藏发件人地址的邮件'
message = '这是一封通过编程方式发送的邮件，发件人地址被隐藏。'

send_email(sender_email, sender_password, recipient_email, subject, message)
