Keep complaining until they fix it.  If Amazon doesn't fix it, don't use 
them.  If they're not going to make their connection hosting friendly 
then they don't deserve you as a customer.  Find a company that does 
deserve your business.  If that's too expensive, then live with it, or 
don't host your own mail.
