We already have a rather well working filter that very rarely rejects
any valid emails.   That is around 300 to 900 per day (yes, we do collect
them all into daily message folders.)

Postings by non-members are rare - and even for those regular posters
that don't want to receive but do want to send we could have a simple
"subscribe to linux-posters -list" rule.  Nevertheless that does not
validate message poster person to be list member, just that the email
address in the "From:" header is known.   (I have been receiving for
years some email virus that claims to be coming from Alan Cox...)

So, having a well working web-based "approve these" filter (something
totally different from what Mailman does - that does not work with
tens of thousands of messages in the moderation queue) that gets only
a very small subset of things could work -- but whom would you trust
to be the moderator ?  If anybody could become one (for ease to get
people to do it), could they still do similar stupidities as these
recent "lets subscribe  linux-kernel  -list on many email lists"
attacks have tried to be ?

Having two-tiered moderation could work -- taboo-filters reject
pure junk, and that does not arrive to voluntary moderators at
all. Then rest can be processed by volunteers, and all that they
get (via dedicated linux-list-moderators  -list or some such) is
an email every 3 hours of "NN messages in moderation queue" along
with queue management tool URL.  No authentication, just queue
processing, and the tool shows only beginnings of ten oldest
messages in the queue with some smart javascript to optionally hide
99% of message headers (and to reveal them when somebody wants to
peek inside to know what is happening..)

That way the burden shouldn't be too bad (burden that will kill such
moderation effort) while likely valid messages still do get thru.

If they need help (horrible flood of junk passed thru pre-filters)
they can issue a help request to system postmasters to tune the
pre-filters and to use some heavy-duty tools to shove away most
junk from the queue.

Any volunteers to write couple perl tools ?
