Yes, it's their service and the C-R thing sucks. I'm not using
@uol.com.br but that's not the point, see below.

Good research really, but do you see that petsupermarket@uol.com.br
isn't subscribed in our MLs ? It's other address that is forwarding to
petsupermarket@uol.com.br. The mass-unsubscribe side effect here is
that we're hurting users when petsupermarket@uol.com.br is still free
to mail our lists. What's the rationale ? Force uol users after
unsubcribe them to ask their ISP send a reply for Debian ?
