Email validate

The main goal of this module is to prevent the use of disposable emails (DEA) when registering and updating a user profile.
We have collected a number of actual and effective methods of checking DEA and implemented them in one module.

Features

Module implements the list of next constraints:
Google Disposable Email
Prevents the use of emails such as:

• user+@gmail.com
• user+@googlemail.com
• u.ser@googlemail.com (dots in any place)

if user with email address user@gmail.com already exists.

Yandex temporary emails
Prevents the use of emails such as

• u-ser@yandex.com if u.ser@yandex.com already exists
• u.ser@yandex.com if u-ser@yandex.com already exists
• user@(ya.ru|yandex.ru|yandex.by|...) if user with user@yandex.com email already exists and so it is for every domain.

E-mail domain black list
Provide internal black list which contains the list of email domains to block.

Temporary email checking on https://block-temporary-email.com
Implement checking of emails on https://block-temporary-email.com.
Required to create account and get API key.

All these checks can either be enabled or disabled as needed.

Post-Installation

Install the module and enable it as usual, then open configuration page at
Configuration | People | User Email validation (/admin/config/people/email_validate)
Select and save which constraints should be enabled.
