What is D T C Q

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.

/// D - the total number of delivered messages
///
/// T - the total number of transiently failed messages
///
/// C - the number of open connections
///
/// Q - the number of ready messages in the queue

can C be increased?

The MTA opens as many connections as it needs to reach full throughput, up to any configured connection limits in your traffic shaping config, if the connection count isn’t at the configured limit, the MTA does not need more connections.

what will be key word to set in shaping config

["default"]
connection_limit = 100
max_connection_rate = "10000/min"
max_deliveries_per_connection = 100
max_message_rate = "1000/s"
idle_timeout = "60s"
enable_tls = "Opportunistic"
consecutive_connection_failures_before_delay = 100
max_ready = 200

this is what I have set in the shaping config

but in the queue summary it taking only 5 connections.

The the MTA does not consider additional connections to be necessary.

Shaping config is limits, not fixed directives.

ok let me check that, thanks!

can we purge the Q - the number of ready messages in the queue using kcli?

I would really like you to explain to me what deficiencies you see in the search function of our documentation.

purge means bounce,

Please explain to me how we can bounce the ready queue, as I can see the options for schedule queue to bounce using kcli

What search in the documentation did you try so that I can ensure we provide better search results for others with your question

I have spent the last year writing nearly 300 pages of documentation so I can only assume that when you have a question you started with a search of the documentation and having found no answer you then asked us a question here. I assume at the very least you search for KCLI, and then looked at the documentation page for it.

And based on that assumption I can only assume I need to improve the search function in some way.
