does not help either. (I refer to it as basis for doing

The smtpserver can work without being root -- after it
has created the listen socket, it actually turns itself
into ``daemon''. Except for doing ETRN support it does
need to become root, because the control message is sent
straight to the scheduler and the POSTOFFICE/transport/
directory is owned by root with protection 755 ...
Perhaps I need to write such a utility program, however
I don't have any good ideas on how it could be invoked
from fingerd, for example.
Easy initial version could be a shell script run from
