Configure Private Address for WebSocket
Define Private Address via API
The API is the easiest way to reserve a private address. A simple HTTP POST will do.
curl -s --request POST https://mailsac.com/api/addresses/user1%40mailsac.com?_mailsacKey=API_KEY

Select Manage Email Addresses and choose settings next to the email address you want to configure for Websocket.
