Thanks Quan. The delays I'm seeing are between initial spooling and the very first delivery attempt.
Currently seeing a number of messages in the outgoing mailQueue with next delivery of 1969-12-31T23:59:59.999Z They do not seem to be progressing. I've noticed that when a message is first queued it has this date but only for a very short period until it's picked up by the deliverer. Suggests to me that some thread has died? A call to the healthcheck suggests everything is fine: {"status":"healthy","checks":[{"componentName":"Guice application lifecycle","escapedComponentName":"Guice%20application%20lifecycle","status":"healthy","cause":null},{"componentName":"MailReceptionCheck","escapedComponentName":"MailReceptionCheck","status":"healthy","cause":null},{"componentName":"EventDeadLettersHealthCheck","escapedComponentName":"EventDeadLettersHealthCheck","status":"healthy","cause":null},{"componentName":"EmptyErrorMailRepository","escapedComponentName":"EmptyErrorMailRepository","status":"healthy","cause":null},{"componentName":"Embedded ActiveMQ","escapedComponentName":"Embedded%20ActiveMQ","status":"healthy","cause":null}]} Kind regards Matt Pryor Research and Development Manager The International Presence Group of Companies EMAIL: pr...@presencebpm.com URL: www.International-presence.com On Fri, 1 Aug 2025 at 18:14, Quan tran hong <quan.tranhong1...@gmail.com> wrote: > Hi Matt, > > > What could be the cause of this I wonder?
