Thank you Deoren for your thoughts.
Welcome. Hopefully others will chime in with more details.
I've seen some junk hostnames already appear in the logging directory. Thanks for your explanation. I can create an IP to Hostname table like IP:HOSTNAME pairs, but unsure how rsyslog could use this to lookup the incoming IP address. Is there a feature in rsyslog for this?
There is, but I forgot that when I mentioned the functionality that the old version you're using may not have support for it (or it may be a buggy version if present).
See my recent responses to the list for a link back to the docs. Hopefully I'm wrong and it is available for your version, but I suspect it isn't.
