Can you, please tell me how much time it takes to email from schedule queue to ready queue.
Hey there @youthful-zorse, thanks for posting. Please read the “Troubleshooting” and “How to Ask for Help” buttons below. If you would like a 1:1 support session from the KumoMTA team, details are at the “Book a Support Session” button below.
The scheduled queue contains messages ordered by their next delivery attempt time. When initially received, a message is eligible for delivery immediately and will move directly into the ready queue.
If a message is transiently failed it will be placed back into the scheduled queue using an exponential backoff based off the age of the message. The parameters for the backoff are controlled via make_queue_config - KumoMTA Docs is its related options.
If the ready queue is full when a message wants to move from the scheduled queue, it will get delayed by a randomized delay of approximately 1 minute before being considered again.
thank you @free-spirited-yorksh for the explanation.
