Viktor,
What I'm looking for is the envelope recipient. I need a way to force an
unqualified to address to a domain I can blackhole. I've got an application
that feeds into these systems that will allow its users to enter badly formed
email addresses. What I want to do is to just swallow those in postfix. What I
was attempting to do, was get the envelope to to be forced to @blackhole.local,
and then I just discard that w/ a transport map.
Is there a way to accomplish that?

Note the string "_header_" in the last two parameters.

You're submitting an empty message (no headers), with an unqualified
*envelope* recipient address. And you log samples in any case only
provide evidence of the resulting envelope.

The envelope recipient was qualified with @$myorigin as configured. If
you were expecting something else, you've misinterpreted the
documentation.
