It looks to me like jlmiller is an alias to something @mmtlnx.mmtnetworks.com.au

most likely you have something like "jlmiller: jon" in your /etc/aliases 
so it appends "myhostname" which is mmtlnx.mmtnetworks.com.au

However postfix is not configured to accept email under that domain which 
is why it gets all confused when it "loops back to myself"

The solution: add mmtlnx.mmtnetworks.com.au to mydestination
