Sort of.  What I was talking about was using mail-back confirmation as an option for allowing postings from email addresses that Mailman has never seen before (i.e. non-validated).  The confirmation message would be a sort of on-demand validation that would optionally be enough to allow that email address to post to the list.  It still doesn't solve any of the authentication problems with those email addresses.
