## exceptions.RecipientsRefusedError


The service refused every recipient, so nothing was submitted.


Usage

``` python
exceptions.RecipientsRefusedError(
    message,
    /,
    *,
    refused,
    backend=None,
)
```


Only [Connection.send](Connection.md#epistole.Connection.send) raises it, so its `__cause__` is `None`. When the service refuses only some recipients, the send returns them in `SendResult.refused` instead.
