:::endpoint DELETE /v1/me/mail/blocked-senders/{id}

From then on mail from that sender is delivered again. What was refused while
the block stood is not coming back: it was never stored.

The path takes the `id` from [the list](/docs/api/mail/blocked-senders). A
number there answers `404`, like an entry that does not exist.

## Request

```bash
curl -X DELETE https://api.proppertrading.com/v1/me/mail/blocked-senders/blk_5ws77sgyjhhkqb66 \
  -H "Authorization: Bearer ptat_9f2c1a44_3b8e7d2f5c9a1b4e6d8f0a2c4e6b8d1f"
```

## Response

`204`, no body.
