Oh, yeah, I forgot about that part. Thanks. I put the unseen pipe at
the end of the filter, but the beginning is like the sample on
exim.org for killing virus-look-alikes.

The shadow transport doesn't have any "first_delivery" conditions for

For society, it's probably a good thing that engineers value function
over appearance.  For example, you wouldn't want engineers to build

radiation inside.
