Validate_email

Validate_email is a package for Python that check if an email is valid, properly formatted and really exists.

INSTALLATION

First, you must do:

sudo python setup.py install

Extra

For check the domain mx and verify email exits you must have the dnspython package installed:

pip install dnspython

For locally stored database and known domain lookups you must install sqllite3 and create a database:

vi .env
export GOOGLE_USER=example@gmail.com
export GOOGLE_PASS=example_pass
export YAHOO_USER=example@yahoo.com
export YAHOO_PASS=example_pass
export WLIVE_USER=example@hotmail.com
export WLIVE_PASS=example_pass

pip install sqllite3
source .env
erb -T '-' create_db.py.erb > create_db.py
python create_db.py

UNINSTALL

sudo python setup.py install --record files.txt sudo bash -c 'cat files.txt | xargs rm -rf' rm files.txt

USAGE

Basic usage:

from validate_email import validate_email
is_valid = validate_email('example@example.com')

Checking domain has SMTP Server

Check if the host has SMTP Server:

from validate_email import validate_email
is_valid = validate_email('example@example.com',check_mx=True)

Set Up Debug Logging

import logging import sys

root = logging.getLogger("validate_email") root.setLevel(logging.DEBUG)

ch = logging.StreamHandler(sys.stdout) ch.setLevel(logging.DEBUG) formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s') ch.setFormatter(formatter) root.addHandler(ch)

from validate_email import validate_email is_valid = validate_email('wello7@yahoo.com',sending_email='hydration@yahoo.com',check_mx=True,debug=True) print("MX CHECK: %s") % (is_valid) is_valid = validate_email('wello7@yahoo.com',sending_email='hydration@yahoo.com',verify=True,debug=True) print("VERIFY: %s") % (is_valid)

Verify email exists

Check if the host has SMTP Server and the email really exists:

from validate_email import validate_email
is_valid = validate_email('example@example.com',verify=True)

Verify email exists on a server that implements callback verfication

Check if the host has SMTP Server and the email really exists:

from validate_email import validate_email
is_valid = validate_email('example@example.com',verify=True,sending_email="valid@example.org")

valid@example.org must be a valid e-mail that you control.
