New moderation policy

[Ross Paterson]

It seems that the policy of rejecting non-member email has had the
unexpected consequence of an increase in postings being sent to the
wrong list, because people find it too much trouble to subscribe to
the right list (and unsubscribe again) just to send one message.
Thus we see Hugs bugs in the haskell list, etc.  As people become
accustomed to the policy, they do this without trying the other
list first, so it won't show in your logs.

Would it be possible to white-list members of any haskell.org list
for posting to any list?  (Or just white-list subscribers of haskell
for posting to any list?)
