Purpose

It validates email for application use (registering a new account for example)

Usage

In your Gemfile :

gem 'valid_email'

In your code :

require 'valid_email'
class Person
  include ActiveModel::Validations
  attr_accessor :name, :email

  validates :name, :presence => true, :length => { :maximum => 100 }
  validates :email, :presence => true, :email => true
end


p = Person.new
p.name = "hallelujah"
p.email = "[email protected]"
p.valid? # => true

p.email = "john@doe"
p.valid? # => false

p.email = "John Does <[email protected]>"
p.valid? # => false

You can check if email domain has MX record :

validates :email, :email => {:mx => true}

Or validates :email, :email => true, :mx => true

If you don't want the MX validator stuff, just require the right file

require 'valid\_email/email_validator'

Or in your Gemfile

gem 'valid_email', :require => 'valid_email/email_validator'

Note on Patches/Pull Requests

Fork the project.
Make your feature addition or bug fix.
Add tests for it. This is important so I don’t break it in a future version unintentionally.
Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
Send me a pull request. Bonus points for topic branches.
