Python使用ipaddress发送电子邮件

import smtplib
from email.mime.text import MIMEText

def send_email(sender, receiver, subject, message):
    msg = MIMEText(message)
    msg['Subject'] = subject
    msg['From'] = sender
    msg['To'] = receiver

    smtp_server = 'smtp.example.com'  # 设置SMTP服务器地址
    smtp_port = 587  # 设置SMTP服务器端口号
    smtp_username = 'your_username'  # 设置SMTP服务器用户名
    smtp_password = 'your_password'  # 设置SMTP服务器密码

    try:
        smtp_obj = smtplib.SMTP(smtp_server, smtp_port)
        smtp_obj.starttls()
        smtp_obj.login(smtp_username, smtp_password)
        smtp_obj.sendmail(sender, receiver, msg.as_string())
        smtp_obj.quit()
        print("邮件发送成功")
    except smtplib.SMTPException as e:
        print("邮件发送失败：" + str(e))

sender = 'sender@example.com'  # 发件人邮箱
receiver = 'receiver@example.com'  # 收件人邮箱
subject = '测试邮件'  # 邮件主题
message = '这是一封测试邮件'  # 邮件内容

send_email(sender, receiver, subject, message)
