#validate_each(record, attribute, value) ⇒ Object

Validates email address. If MX fallback was also requested, it will check if email is valid first, and only after that will go to MX fallback.

Examples:

class User < ActiveRecord::Base
  validates :primary_email, :email => { :mx => { :a_fallback => true } }
end
