Addresses this message may leave from
A list of sending addresses this message is allowed to use, overriding the node's own arrangement.
In detail
The most direct of the five ways to choose a sending address, and the only one expressed per message: the job names the addresses, the engine picks from them. Worth placing against the others. Intake mapping chooses by the address a message was submitted to; a pool chooses by name; a rewrite rule chooses by condition; per-address queues choose by where the job was published. This property is the explicit form, useful exactly when the sender already knows which address a message belongs to — which, for warm-up traffic, Hub does.
What happens if you get it wrong
An address listed that the node does not have.Unverified: either the message fails to bind or another address is used. Worth establishing before Hub relies on this property.inference
