i need script python scanner email valid or not

Here is a Python script that can scan and validate email addresses:

import re
import smtplib

def validate_email(email):
    # Checking the email pattern
    pattern = r'^[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}$'
    if not re.match(pattern, email):
        return False
    # Checking if the email is valid
    try:
        domain = email.split('@')[1]
        smtp = smtplib.SMTP(domain, timeout=5)
        status, message = smtp.ehlo()
        if not status == 250:
            return False
        smtp.quit()
        return True
    except:
        return False

# Testing the function
email1 = 'example@gmail.com'
email2 = 'example@invalid'
email3 = 'example@outlook.com'
print(validate_email(email1))
print(validate_email(email2))
print(validate_email(email3))

In this script, the validate_email function takes an email address as input and returns True if the email is valid and False if it is not.

First, it checks whether the email matches the standard pattern using a regular expression. If it doesn't match, it returns False.

If the email matches the pattern, the script then attempts to validate the email by checking if the domain exists and can be reached through an SMTP connection. If the connection is successful, the function returns True. If not, it returns False.

The script includes a test of the validate_email function using three example email addresses.
