title: Dealing with SMS Spoofing
body: <p>I'm working on a web service that would use an SMS gateway to receive instructions from customers. Since this would be a commercial product I would like to implement a safeguard to protect our system from SMS spoofs. I don't want people impersonating others by spoofing their number. </p>
  
  <p>I've noticed that Twitter allows people to tweet through text messages, how can they make sure that messages are actually genuine?</p>
  
  <p>Is this possible, and if so how do I accomplish this? Or should I ignore this and just deal with it through support should they get through.</p>
