Thanks.
Probes with 'sendmail -bv' work, from my shell, with no error. :-/
Since it's not identical to the path/process an inbound mail takes, which I
think is what this means

I susepct it's not touching whatever I've done to cause my problem.
I turned up debug logging (wow, noisy!), and am staring at this bit which IIUC
is the address verify in progress. Notice the ERROR,

That
input attribute value: mail for example.com loops back to myself
can't be good. I wonder if that's what's causing the almost immediately
subsequent "Recipient address rejected" (for now, now relegated to just a
reject_warning)?
What I can't yet grasp is which piece is causing the problem.
If what Noel said is true
The "loops back to myself" message occurs when postfix is greeted with
its own HELO hostname.
there's a wrong HELO, or hostname setting ... somewhere. Since it's an
'internal' process, I can't seems to identify where the problem is. The
increased verbosity on the psint process isn't enough to tell me, apparently.
Where do I look for this cause?
