如何延迟发送电子邮件后运行的宏？

import smtplib
import time

def delay_send_email(subject, body, recipient, send_time):
    current_time = time.time()
    delay = send_time - current_time
    time.sleep(delay)

    # 发送邮件的代码
    # 这里使用smtplib库来发送邮件

    smtp_server = 'smtp.example.com'
    smtp_port = 587
    sender_email = 'your_email@example.com'
    sender_password = 'your_password'

    message = f'Subject: {subject}\n\n{body}'

    with smtplib.SMTP(smtp_server, smtp_port) as server:
        server.starttls()
        server.login(sender_email, sender_password)
        server.sendmail(sender_email, recipient, message)

# 调用延迟发送邮件的函数
subject = 'Delayed Email'
body = 'This email is sent after a delay.'
recipient = 'recipient@example.com'
send_time = time.time() + 3600  # 延迟1小时发送

delay_send_email(subject, body, recipient, send_time)
