Set up an automated SMS server with Android (and a computer)? I'm looking for a way to set up an SMS server (I don't know if there is better terminology for this, but probably).

What I want:


use the phone as an SMS gateway for an automated server 
let the phone send and receive messages
use a computer to command the phone what to do


Specific example use case: The phone gets an SMS message [family] The party today will start at 2pm. Which the computer will interpret and will order the phone to send the message over to all the numbers the computer has in the family list. Or f.e. [add]family,0123456789 to let it add numbers to lists.

So what do I exactly need?

An app that can send all it's incoming messages to an HTTP server and can receive orders from that same server. Of course USB would be a better method than HTTP because it's safer.
SMS Gateway from the android store does exactly what you want.


  
  Periodically checks for e-mails via POP3 and send them via SMS.
  Send SMS by HTTP GET request on its internal webserver.
  Forward received SMS to desired e-mail via SMTP.
  Forward received SMS by calling remote webserver via HTTP GET.
