My apologies. I did not confirm that what I did already sent you was the message received by the user. The mailing list address is ssan@lists.naturalintelligence.us and it seems as though this became an alias for this single user christian@sewagesludgeactionnetwork.com .
Not exactly. What happened is this:
% host lists.naturalintelligence.us lists.naturalintelligence.us has address 45.33.28.111 lists.naturalintelligence.us mail is handled by 10 box.ecovillage.cc. % host box.ecovillage.cc. box.ecovillage.cc has address 45.79.28.18 box.ecovillage.cc mail is handled by 10 box.ecovillage.cc.
'lists' and 'box' are different systems, it appears, because they have different IP addresses (45.33.28.111 vs. 45.79.28.18). Because of the MX record described by "lists.naturalintelligence.us mail is handled by 10 box.ecovillage.cc.", the mail sent to the list at 'lists' is going to 'box', not 'lists'. I guess that Mailman is installed on 'lists', not 'box', so Mailman never sees the post. My guess is that what you want to do is to change the MX for 'lists' to itself in the DNS, and you probably also need to do something about the webserver if you want 'lists' to offer Mailman services, since currently it presents the same page as 'naturalintelligence.us' which presents the same page as 'www.communityseekers.org'.
Why that message is eventually delivered to 'christian' at ssan, I don't know, but this appears to have nothing to do with Mailman itself. We would need to see the configuration for the MTA (appears to be Postfix) on 'box' to figure this out.
There seems to be a whole complex of domains involved here. We're happy to help you with Mailman even if that involves the DNS, MTA, and webserver configurations for Mailman services, but fixing up the DNS, mail service, and webserver configurations for a hosting service is really above our pay grade. You may want to hire a consultant for this, because the configuration seems suboptimal to me, but I don't know what you're trying to do.
