AM o lista de emailuri ( gen example@example.com) si o lista destul de marisoara ( undeva la 10k)
nu vreau sa imi stric repul la email


def validate_email(email):
    try:
        domain = email.split('@')[1]
        # Check if the domain name is a public email provider
        if domain in ['gmail.com', 'yahoo.com', 'hotmail.com', 'aol.com']:
            # Open a new CSV file for writing the email addresses for this domain
            with open(f'{domain}.csv', 'a') as outfile:
                # Write the email address to the appropriate CSV file
                outfile.write(f'{email}\n')
            return f"{email} exists"
        else:
            # Resolve the MX records for the email address domain
            mx_records = dns.resolver.resolve(domain, 'MX')
            # Sort the MX records by priority
            mx_records = sorted(mx_records, key=lambda x: x.preference)
            # Loop through each MX record and try to connect to it
            for mx in mx_records:
                try:
                    # Connect to the SMTP server
                    smtp_conn = smtplib.SMTP(host=str(mx.exchange), port=25, timeout=5)
                    # Send a HELO command
                    smtp_conn.ehlo()
                    # Send a MAIL FROM command
                    smtp_conn.mail('cornatul@apple.com')
                    # Send a RCPT TO command for the email address
                    status, _ = smtp_conn.rcpt(email)
                    # Check if the email address was accepted by the SMTP server

                        return f"{email} exists"
                except:
                    # Print an error message if there was a problem connecting to the SMTP server
                    continue
                finally:
                    # Close the SMTP connection
                    smtp_conn.quit()
            else:
                return f"{email} does not exist"
    except:
        return f"Could not validate {email}"
