While checking kumomta log, showing some errors that is not understandable. Iam using Golang package to sent emails

Hey there @kindhearted-deer, while we would like to respond to every question raised here, the frequency and nature of your questions are far beyond what we at Kumo Corp can support without financial support from your organization.

You may continue to ask questions in the hope that someone from the broader community will help, but you should expect that Kumo Corp will not spend any time beyond a cursory glance to see if your questions are well-qualified and can be easily dealt with.
