Why on earth are you trying to implement a technical solution to this 
problem?

What if you really need to mail sbcgobal.com or maildomain.com some day?  
Either you can't, or you take this rule away again, in which case your 
problem comes back.

This is a user education issue, not a "crow-bar in any inappropriate fix 
to compensate for naiive or careless users".

At least you could give them an address book, then they don't need to 
(mis)type anything.
