Apparently the MTA has whatever virtual maps/aliases are required to
deliver to <ecovillagenewsletter at ecovillagenewsletter.org> since I
assume the list works, but it is missing those for
<ecovillagenewsletter-request at ecovillagenewsletter.org> and how many
others of <ecovillagenewsletter-admin at ecovillagenewsletter.org>, 
<ecovillagenewsletter-bounces at ecovillagenewsletter.org>, 
<ecovillagenewsletter-confirm at ecovillagenewsletter.org>, 
<ecovillagenewsletter-join at ecovillagenewsletter.org>, 
<ecovillagenewsletter-leave at ecovillagenewsletter.org>, 
<ecovillagenewsletter-owner at ecovillagenewsletter.org>, 
<ecovillagenewsletter-subscribe at ecovillagenewsletter.org> and 
<ecovillagenewsletter-unsubscribe at ecovillagenewsletter.org>, all of
which should be deliverable in a "plain-jane installation".

This is in the MTA configuration and possibly involves Mailman since it
appears that mail.bytesmiths.com is running Postfix and you may be
using Mailman-Postfix integration for automatic alias generation. If
this latter is the case, you need to configure the things discussed in
both sections 6.1.1 and 6.1.2 at
