[Alfred]

Hi,

i upgrade from 2.0 to 2.1 the command /var/mailman/bin/newlist
can not create a new list, over the web i like to create a new list
called test but after click the create button it shows me the error:
Error: Illegal list name: test at mail
but i dont fill a @ in the form and from where comes "@mail" ???

thanks

Alfred
