Part of the problem is the term mail server can be confusing because
there are two mail servers in the picture, a receiving mail server and a
sending mail server. Mailman needs run on the same machine the receiving
mail server is on otherwise your aliases will not work. The reason is
because when the receving mail server receives an email destined for a
mailman list the mail server will via its aliases determine the
destination for that list email is a program called mailman, thats what
all those aliases are all about. The receiving mail server then hands
the incoming list email to the program mailman. It can only give it to
the program mailman if mailman is running on the same machine.
Mailman in turn takes the email it received and looks up all the members
of the list and forwards the email to each of them. To do this mailman
invokes a sending mail server. Often the sending and receiving mail
servers (SMTP) are the same and run on the same box. But you can direct
mailman to use a different sending SMTP server via the SMTPHOST
Summary: mailman and the receiving SMTP server must be on the same
You description is a bit confusing because the way I read it mailman has
in fact received the list email (your previous post shows mailman
sending smtp posts). It could only have done that if it the its running
on the same machine as the receiving SMTP server and the aliaes are
correct. I suspect what actually occurred is those are examples from
mail sent on the machine mailman is running on where everything will
