Stephen,
Thanks for the clarity :-)
Looks like this was an error on my end. Seems Postfix has a second "journalctl" unit that logs the delivery attempts, whereas I was polling "journalctl -u postfix.service" which gave me the impression message delivery was not being attempted, it turns out "journal -u system-postfix.slice" actually had the relevant data, then it also dawned on me I should have been also checking "mailq" which clearly showed there was an email delivery issue that was caused by the server itself.
Ugh a bug.
Anyways, all is good now. Moving onto the next challenge.
