网页邮件地址的SMTP发送失败

以下是一个代码示例，用于解决网页邮件地址的SMTP发送失败问题：

import smtplib
from email.mime.text import MIMEText

def send_email(sender_email, sender_password, receiver_email, subject, message):
    try:
        # 创建邮件内容
        msg = MIMEText(message)
        msg["Subject"] = subject
        msg["From"] = sender_email
        msg["To"] = receiver_email

        # 连接到SMTP服务器
        server = smtplib.SMTP("smtp.gmail.com", 587)
        server.starttls()

        # 登录SMTP服务器
        server.login(sender_email, sender_password)

        # 发送邮件
        server.sendmail(sender_email, receiver_email, msg.as_string())
        server.quit()
        print("邮件发送成功！")

    except smtplib.SMTPException as e:
        print("邮件发送失败：", str(e))

# 填写发件人和收件人的信息
sender_email = "your_email@gmail.com"
sender_password = "your_password"
receiver_email = "recipient_email@gmail.com"
subject = "Test Email"
message = "This is a test email."

# 调用发送邮件函数
send_email(sender_email, sender_password, receiver_email, subject, message)

请确保替换sender_email和sender_password为发件人的真实邮箱地址和密码，将receiver_email替换为收件人的真实邮箱地址。这个示例使用Gmail的SMTP服务器进行发送，如果你使用其他邮箱提供商，请相应地更改SMTP服务器的地址和端口。
