[Zope-Checkins] Spam filtering on this checkins list

According to a bit of empirical computer science (is there really any 
other kind?-), it looks like we're in a good situation for filtering spam 
on our zope.org checkins and collector lists!  It looks like we can use a 
combination of the header-filter rules and non-subscriber rejection to 
admit all checkin notices *and* subscriber postings, and automatically 
reject any non-subscriber postings.

I've established that this works on a test list and checkin repository of 
my own, and am trying it out on this (much) larger list to see if it 
generalizes as i expect.  I've set the action to "hold" for items that 
don't pass muster, so we won't lose any valid traffic if i'm mistaken.  
Bear with me if you get unexpected hold notices on checkins or followups.

If it turns out that it does behave as i expect, i'll post a message to 
zope-announce detailing the settings, so other checkin and collector lists 
admins can institute it on their lists.
