    "created_at": 1704825600,
    "data": {
        "uid": "message-uid-123",
        "action": "blocked",
        "scope": "domain",
        "value": "sender.example.com",
        "reason": "High-volume abusive sending activity detected",
        "user": "smtp-user",
        "forwarding_only": false,

        "occurred_at": 1704825600
    }
}

Field	Description
`uid`	UID of an outbound message from the blocked mailbox or domain; use it to look up the matching message in outbound logs
`action`	Always `blocked` for this event

`value`	The blocked domain or email address
`reason`	Why JetEmail applied the block
`user`	SMTP username associated with the block
`forwarding_only`	Whether the block applies only to forwarded mail
`block_id`	Unique identifier for the block action
