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.
