 validates_format_of :email,
                :with    => /^([a-zA-Z0-9_\-\.]+)@((\[[0-9]{1,3}" + @"\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([a-zA-Z0-9\-]+\" + @".)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)/,
                :message => "is missing or invalid"

Please let me know where is the problem? Is regular expression is wrong?
