def check_domain_expiration(domain, expiration_date):
    today = datetime.date.today()
    if today >= expiration_date:
        send_reminder_email(domain)

    smtp_server = 'smtp.example.com'
    smtp_port = 587

    smtp_password = 'your_password'

    with smtplib.SMTP(smtp_server, smtp_port) as server:
        server.starttls()
        server.login(smtp_username, smtp_password)
