Hello Quim

Given that this is currently implemented on WMCS, I would think that their terms would prevail and certain private mailing lists NOT allowed be copied at all there  (for instance a list where checkusers disccussed about vandal ranges), since it's on an "untrusted" network/servers that shall not contain such private data. Other private mailing lists may qualify, depending on what is actually discussed there (e.g. I would see no issue with a signpost editorial comments mailing list). And obviously, the content of public lists is simply... public.
