Why do yu actually need a *list* for sending such info?

I guess that when you lists get created, the corresponding admins get
added to such list?

Besides, it seems I'm receiving tons of spam messages on that this. Is
post from not subscribers actually needed? What kind of info is sent to
all list-admins?

Yep, I was able to solve the problem when I found this. (the FAQ made me
realize "mailman wasn't running", and then, when running mailmanctl I
found why).
