Message Receiving Model
EMQ supports both one-to-one and one-to-many message receiving models.
The one-to-one receiving model is mutually exclusive reception. For the same message, once it is received by a receiver, and while within the invisible time, it cannot be received by other receivers.
With a one-to-many receiver model, one message can be received by multiple receivers at the same time. However, these multiple recipients must each be under a different Tag.
