Hi

i'm trying to install mailman on my debian server.
I use Exim4 but when i try to use mailman with it i get only an error :(

exim4 -bt 5411@domain.de
R: virtual for 5411@domain.de
R: list for 5411@domain.de
R: system_aliases for 5411@domain.de
5411@post-kutsche.de ->=A0|"/usr/local/mailman/mail/mailman post 5411"
*** Error in setting up pipe, file, or autoreply:
pipe_transport unset in system_aliases router

this is my systemalias:
system_aliases:
