Forbid certain list names
A list had a name like xx-admin, and were able to do this fine. However, messages sent to xx-admin@lists.riseup.net didn't work, presumably because sympa tried to send the mail to the admin of the list xx, which, in this case, didn't exist. IF the list did exist, then the message would presumably go to the admin of that list, rather than the intended list.
Probably we should ban list names that end in -admin or -editor. There might be other internal sympa keywords that we should ban as listnames, but not sure what.
