[Mailman-Users] Aliases problem

[Walter Justet]

Hi, i´m having a problem with mailman 2.1.5+postfix 2.1.5. The server is
working fine for it´s virtual users, i´ve followed the intructions form
README.POSTFIX and created the list, subscribe some users, run the
genaliases script. But these error show up in the log:

Note that where i put domain is the corresponding domain, and where it says
hostname is the fqdn for that host, i don´t know why it translate in that
way the email address.
Here´s the output from postconf -n:
