How do I use my mailing list to set up a newsletter?
Create the mailing list using the Site Manager.
Your mailing list should now be available at http://www.example.com/mailman/listinfo and you can administer the list at http://www.example.com/mailman/admin
A newsletter is known in mailman as an "Announce Only List."
To configure for a newsletter under "General Options" set "Where are replies to list messages directed?" to "Explicit address"
Then set the "Explicit Reply-To: header" to me@example.com, where me@example.com is the address you want people to reply to.
Then under "Privacy options" -- "Subscription rules" set "Who can view subscription list?" to "List admin only" and under "Sender filters" set "By default, should new list member postings be moderated?" to "Yes."
Then under "Membership Management" -- for "Membership List," make sure everyone EXCEPT me@example.com has the "mod" box checked.
Visit the mailman website for more documentation on other mailman settings.
