After some experiments: It (transport_filter) doesn't seem to be set up
the same way as the pipe command. The environment is that what Exim got
from the caller.

If you could pass information via the environment, it would be visible
in the process information (/proc, ps).

But you can use headers_add = … and let your filter act on these headers
(and remove them during processing)
