mailing lists: please restore all

There are mailing lists that are still down.

I believe it is wrong approach to send emails to mailing list owners and
restore only lists where list owners replied explicitly that the list is needed.

Other way araound: all lists should be restored and only those explicitly requested
may be removed.

Note, the owner may be inactive, but there are other people who need the lists:
other subscribers, future subscribers, etc.
