Prevent people from one team sending messages to people from another team

Troubleshooting

Hey folks!

I have my own Mattermost server and I would love to know if it is possible to prevent people from one team to send DMs to people from another team? The situation is that I need to host two very different types of people on one Mattermost server and don’t want them to communicate between each other.

Thanks a lot!
