So, if you don't want to set the lists to discard non-member posts for
the reasons you explain, is it that much better to reject them at SMTP
time. Granted this avoids the issue of backscatter to bogus addresses,
but it isn't very helpful to the non-member senders of 'legitimate' posts.
A better solution is to use various sendmail tools to identify and
reject spam in general rather than just non-member list posts.
