You could certainly add uux and uux to the list of legal remote commands, but I confess that my memory is also dim about whetheruucp file a!b!c would be translated automatically. It has indeed been a while...
I'm pretty sure it was adding 'uucp' in the commands list that enabled the behaviour. HDB might have used a different config file syntax for turning this on. I would have to dig out the source code to remember the details. The command syntax you show above worked -- UUCP handled the re-queueing internally.
