Verify Emails

[Samuel Muiruri]

There's a python package for validating emails exists "validate_emails" https://pypi.python.org/pypi/validate_email think it would be useful to include it's features inside django so you can parse if emails exists before sending so you only send emails to those emails that do exists and also use it to get back those that don't so you can remove them from your list like dummy emails provided to your subscription page.

Hi,

Nothing prevents you to create django validator that does use that package.

Including functionality that package provides would add more dependencies to Django (pyDNS) which greatly reduces chances to get existence verification into Django itself.

And Django already has email validator built-in.

why not use an email validator provided by Django ?

https://docs.djangoproject.com/en/2.0/ref/validators/#emailvalidator

The problem with the pypi module is that to validate that an email
exists it simply looks for server in DNS (which is slightly better than
the Django validator), but that doesn't mean that the :

* Email server will accept emails from you - or your service
* or that the user exists on that server ( even if the server exists).

The only real way to validate that an email server is entirely valid is
to send an email to it, asking for a reply. Email parsing will only go
so far.

In theory there is a defined protocol to allow clients to  query email
servers for is valid email addresses - but most servers are set to
ignore those requests - for obvious reasons.

If you do your own email-sending code you can break off the sending after the server sends "RCPT', that'll work regardless.
