Block SIM receive SMS only from Emnify or valid senders

We are working on a feature that requires the usage of SMS.
For that we've already enable the SMS policy, and test sending SMS to the SIM through the website and emnify API with success.
We have some doubts regarding the source of the SMS.
I've tried sending SMS from my mobile phone and is possible, this means that we need to filter the receive SMS by sender, but the "shortID" is possible to "fake".
Is there a possibility to add a whitelist on emnify API which let us add valid senders?
We intend to use only emnify API to send SMS, and reject any other message, should not be sent. Is possible have this type of control with emnify under policy configurations?

Hi Pedro,
You can disable different types of SMS communication in the service policy.
SMS Firewall
SMS comes with risks, such as increased device power consumption, attacker infiltration, and additional costs. That’s why emnify allows you to configure SMS MO and SMS MT limits on an individual or a group of devices or switch them off completely. You can also turn on or off internal P2P SMS (that is, devices managed by the emnify IoT SuperNetwork) or external P2P SMS (external communication from and to any other devices).
Hope this helps!
Jeff

Hello Jeff Stahlnecker
Yes, we have tried those settings but we still can send SMS from a mobile phone, even though we have blocked "external parties".
