validates_email_address_of

This provides an email validator for ActiveRecord 3.

Installation

Add this line to your application's Gemfile:

gem 'validates_email_address_of'

And then execute:

$ bundle

Or install it yourself as:

$ gem install validates_email_address_of

Usage

Here is the quick and dirty way to include validates_email_address_of

class User < ActiveRecord::Base
  attr_accessible :email, :password, :password_confirmation
  has_secure_password
  validates :email, :email_address => true
end

There are three separate validation tests that get more and more complete. Each test is independent of the others. While all test are indepent if a lower level test fails it will skip the high level test. All test run by default.

Format

This is a basic RegEx validation and only checks that the email is in the correct format. You can enable or disable by specifying the :format option.

validates :email, :email_address => { :format => false }

MX

This test gets even more acurate than just checking the format. This checks that the domain has at least one MX record attached to it. this can be disabled similarly to format, except with the :mx option.

validates :email, :email_address => { :mx => false }

SMTP Address Verification

This is the ultimate test. This will actually contact the mail server and ask it to verify that the provided email exists. While this guarentees the email will exist it is slow, due to the slow run we suggest only running this test on create. This can be controlled with the :smtp option.

validates :email, :email_address => { :smtp => flase }
