iam try to sent bulk email (50000 / minute)
Hey there @kindhearted-deer, 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.
Start by using iostat to determine if your disk io is at 100%, if so you will need a faster disk.
when the server starts up, the spool must be enumerated fully before new mail can be accepted. While enumerating, new incoming mail is transiently rejected. Once the spool has enumerated, you will be able to inject more mail.
@kindhearted-deer if you have just restarted the service and you have a large amount of mail in queue, it may take several minutes to enumerate it all before being able to inject new messages. If you are still seeing that message 5 minutes after restarting the service, you may want to consider upgrading your hardware.
Thanks for the update @faithful-ostrich @yearning-hyena @free-spirited-yorksh .
Also i have another issue " kumo.domain.com load shedding. Try later (4093)". Is this issue related to above scenario ?
load shedding means that too much ram is being used, so no more messages will be accepted until the memory usage is reduced.
ok
