Makes use of Twilio to receive SMS messages, and forward them to email addressees.
Push to a Heroku application, and then point a TwiML app at the endpoint https://myapp.herokuapp.com/sms you'll then need to configure a mapping between phone numbers and email addresses like so:
heroku config:set ADDRESSES='{ "+4412345677": [ "email@example.org", "email2@example.org" ] }'
Finally, add an email addon to your Heroku app, or define an SMTP endpoint.
heroku config:set SMTP_URI='smtp://user:password@smtp.yourserver.com:25'
And you're done!
