============================
py3-validate-email
============================
py3-validate-email is a package for Python that check if an email is valid, not blacklisted, properly formatted and really exists.
This module is for Python 3.6 and above!
INSTALLATION
============================
You can install the package with pip::
python -m pip install py3-validate-email
USAGE
============================
Basic usage::
from validate_email import validate_email
is_valid = validate_email(email_address='example@example.com', check_regex=True, check_mx=True, from_address='my@from.addr.ess', helo_host='my.host.name', smtp_timeout=10, dns_timeout=10, use_blacklist=True)
:code:`check_regex` will check will the email address has a valid structure and defaults to True
:code:`check_mx`: check the mx-records and check whether the email actually exists
:code:`from_address`: the email address the probe will be sent from,
:code:`helo_host`: the host to use in SMTP HELO when checking for an email,
:code:`smtp_timeout`: seconds until SMTP timeout
:code:`dns_timeout`: seconds until DNS timeout
:code:`use_blacklist`: use the blacklist of domains downloaded from https://github.com/martenson/disposable-email-domains
The function :code:`validate_email_or_fail()` works exactly like :code:`validate_email`, except that it raises an exception in the case of validation failure instead of returning :code:`False`.
Auto-updater
============================
The package contains an auto-updater for downloading and updating the built-in blacklist.txt. It will run on each module load (and installation), but will try to update the content only if the file is older than 5 days, and if the content is not the same that's already downloaded.
The update can be triggered manually::
from validate_email.updater import update_builtin_blacklist
update_builtin_blacklist(force: bool = False, background: bool = True,
callback: Callable = None) -> Optional[Thread]
:code:`force`: forces the update even if the downloaded/installed file is fresh enough.
:code:`background`: starts the update in a ``Thread`` so it won't make your code hang while it's updating. If you set this to true, the function will return the Thread used for starting the update so you can ``join()`` it if necessary.
:code:`callback`: An optional `Callable` (function/method) to be called when the update is done.
