Email Verifier

Helper validation utility for checking if given email address is real.

Many times as developers we were putting validation statements for checking email addresses format. This gem will complete your existing setups with validator that actually connects with a given mail server and asks if the address in question exists for real.

It also:

• supports Heroku
• supports localization

Installation

Add this line to your application's Gemfile:

gem 'email_verifier'

And then execute:

$ bundle

Or install it yourself as:

$ gem install email_verifier

Usage

To get info about realness of given email address, email_verifier connects with a mail server that email's domain points to and pretends to send an email. Some smtp servers will not allow you to do this if you will not present yourself as a real user.

First thing you need to set up is placing something like this either in initializer or in application.rb file:

EmailVerifier.config do |config|
  config.verifier_email = "[email protected]"
end

Then just put this in your model e. g:

validates_email_realness_of :email

Or - if you'd like to use it outside of your models:

EmailVerifier.check(youremail)

This method will return true or false, or will throw an exception with nicely detailed info about what's wrong.

Customizing messages

Add these lines to your locale file in config/locales:

it:
  errors:
    messages:
      email_verifier: 
        email_not_real: must point to a real mail account
        out_of_mail_server: appears to point to dead mail server
        no_mail_server: appears to point to domain which doesn't handle e-mail
        failure: could not be checked if is real
        exception: could not be sent
