Description:

Server Setup Information:

• Version of Rocket.Chat Server: 0.64.1

Steps to Reproduce:

1. User is muted.
2. Tries to send a message.
3. The result returned is: {"message":false,"success":true}

This was tested on main public server open.rocket.chat using the REST endpoint:

/api/v1/chat.sendMessage

Maybe it helps to point out that on the realtime api the response is different: a["{\"msg\":\"result\",\"id\":\"25\",\"result\":false}"].

Expected behavior:

We should use a proper HTTP status code response. If it's not possible, I think we should at least get a consistent result such as an empty object, but not false.
