Fake / Temp e-mail validator

fake_email_validator.rb

# encoding: utf-8

# Validates that the specified attributes are fake e-mail from temp domains
#
#   class Person < ActiveRecord::Base
#     validates :email, :fake_email => true
#   end
#
#   class Person < ActiveRecord::Base
#     validates :email, :fake_email => { :exclude => ['bobmail.info'] }
#   end
#
#   class Person < ActiveRecord::Base
#     validates :email, :fake_email => { :only => ['bobmail.info'] }
#   end
#
# The validator expects that the e-mail is already a valid e-mail address
# it only check's if it's from a invalid temp domain
#
# If you want to validate only agaist a specific domain use +only+ attribute
# <tt>validates :email, :fake_email => { :only => ['bobmail.info'] }</tt>.
#
# If you want need to remove one or more domains from the default list use +exclude+ attribute
# <tt>validates :email, :fake_email => { :exclude => ['bobmail.info'] }</tt>.
#
# Configuration options:
# * <tt>:message</tt> - A custom error message
# * <tt>:exclude</tt> - A list of e-mails to exclude from the validation list
# * <tt>:only</tt>    - Validate the domains only agaist the provided list
#
# There is also a list of default options supported by every validator:
# +:if+, +:unless+, +:on+ and +:strict+.
# See <tt>ActiveModel::Validation#validates</tt> for more information
