validates_as_email

ValidatesAsEmail

This gem/plugin is a re-packaged and gem'ified version of the original plugin with credit as follows:

Ximon Eighteen [e-mail] Dan Kubb [e-mail] Thijs van der Vossen [e-mail]

This Ruby on Rails plugin implements an ActiveRecord validation helper called validates_as_email. The helper acts as if validates_format_of was used with a regular expression that defines an RFC822 email address conformance test.

The plugin implements the regular expression here:

http://tfletcher.com/lib/rfc822.rb

Which is an implementation in Ruby of a regular expression published by Cal Henderson for PHP here:
