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","escapedCom=
ponentName":"MailReceptionCheck","status":"healthy","cause":null},{"compone=
ntName":"EventDeadLettersHealthCheck","escapedComponentName":"EventDeadLett=
ersHealthCheck","status":"healthy","cause":null},{"componentName":"EmptyErr=
orMailRepository","escapedComponentName":"EmptyErrorMailRepository","status=
":"healthy","cause":null},{"componentName":"Embedded
ActiveMQ","escapedComponentName":"Embedded%20ActiveMQ","status":"healthy","=
cause":null}]}
