A word at the outset here: I predict this will come back to bite you
in a most painful way. As Noel suggested, you're going to run afoul
of some clueless spam checks. Some years back I know that Hotmail/MSN
actually *discarded* such mail silently!
Note also that Postfix itself uses Received: headers as a protection
against mail loops. Let's hope you don't get a loop going!

It's running. To see what it does:

Every non-default service should have its own syslog_name to enhance
your log searches.

That might get too noisy in the logs, but at least you will know your
alternate cleanup service is being used.
