I'd really like the messageId to NOT contain my host, domain, or other
identifying information.  The layout of my LAN systems should be
private, and I don't want spammers harvesting this info.

Any reason it can't be related to a crypto-generated blob based on
maybe UNIX time + hash of machine  name + PID + ... ?

Yours in paranoia...
