php-mailgun-validation

Validate email address with Mailgun’s validation service (Syntax checks, DNS validation, MX validation)
You can view Mailgun’s blog post about the service here: http://blog.mailgun.com/free-email-validation-api-for-web-forms/
An API key is required to use this library, it can be obtained from mailgun’s site after signup:
https://mailgun.com/app/account/security

The service is free, however fair usage limits do apply (detailed in the post linked above).
Mailgun no longer offers this service for free, however this library works fine with the new paid service.
