What's a "typo"?  Suppose I'd be using Lotus Notes, then my adress could
actually look like "Alexander.Skwar/some/where at domain".  This would
resolve to a typo in your case, although that adress is valid.

Never do this!  If you rely on something client-side for checks, you're
in hell, because disabling JavaScript iwll break the check, and forging
the reply sent by the browser is very easy.
