This message's deadline
The moment after which this message is abandoned, set from the node's default at acceptance and overridable per message.
In detail
Every message carries one, whether or not the job set it: we read a result on the stand whose deadline was exactly a day after acceptance, matching the node's max-delivertime. Setting it per message is what distinguishes time-sensitive mail from bulk. A password reset that has not arrived in fifteen minutes is worse than useless, and giving it a short deadline means it fails visibly instead of arriving at the wrong moment; a newsletter can be given longer than the node's default. It is absolute, not a budget: a pause on the domain does not extend it, so held mail can expire while waiting.
What happens if you get it wrong
A long pause applied to mail with a near deadline.The mail expires while held and is never attempted again.inference
