  1. if i insert “@.” in my email field then what happens.
    I found it will validate this email address.
    please give me a proper solution

  2. Blakes function works, but I noticed that if the string contains a long word after the @-sign, the script uses a lot of processor power. This often causes Firefox (3.5.8) or Internet Explorer (7.0) to crash. Test with this string “jfhskdj@jdhrwueyrroqyweuyrs.s”
