Sending addresses known to the cluster
One row per sending address, each with its own broker, exchange and queue — which is how a specific address can be given its own stream of mail.
In detail
The engine fills this table itself: our five addresses were there before we touched anything. The columns beyond ip are the surprise. Each address carries a broker address, an exchange and a queue name, which means an address can be made to consume from a queue of its own. Publishing to that queue is then a way to say "send this from this address" without pools, headers or rewrite rules — a fifth mechanism alongside the four in the SMTP chapter, and the only one that works at the level of the broker. On a stock node every row points at the same outbox, so nothing behaves specially until someone changes it.
