[Mailman-Users] Unknown user

Hi pals

i´ve just installed mailman v2.0.6, taking all the steps from the
INSTALL file.
i´m running an MTA with smrsh, for precaution, i´ve created the symbolic
link under /etc/smrsh for the wrapper (README.SENDMAIL)
the software is installed and running, i can create a list, modify its
description, use the administrative interface and so on. When i create a
list, the mailman sends e-mail for users subscribed, etc, etc.
but when i try to send the confirmation to list-request at myhost, the MTA
returns
5.1.1 <list-request at myhost> User unknown...
the same happens with --> list at myhost

any guess?

best regards
