There are situations when people who aren't subscribed have a
reason for posting. Consider messages that get cross-posted to major
such as linux-kernel.
I agree with you Russell, but I suggest a good compromise is to
moderate unsubscribed posts.
This has a flaw for some types of spammer which are aware of mailing
lists and subscribe to the list, then make a post so this kind of
filter doesn't work so well on list environments like yahoo groups, but
it would cut down on the amount of spam for certain on Debian lists.
It shouldn't be too difficult for someone with access to the list
membership and the list archives to calculate some statistics for the
number of posts/week for different debian lists would be moderated due
to sender address not being subscribed, just to see what kind of burden
it would be for the list moderators.
Also, a workaround for the flaw in this method to avert spam is to
moderate subscriptions, but this will probably be less acceptable to
