A lot of companies now configure their email security software to prepend a “this email came from an external source. Be careful!” notice to all emails that come from outside the company, to try and avoid issues like this.
My company does this. They also have an outside agency regularly send fake phishing emails to everyone. Invariably, some people always fall for it no matter how much education is done. At least, when they fall for the fake phishing emails, though, my company can gauge just how much education is needed to prevent real phishing attempts from succeeding.
