The Mailman mail list service is a relatively new service on the Spirit server. Since the Spirit server project relies upon volunteers to develop services and produce documentation, usually the docs follow the implementation of the service.
Some information is available from the Mailman website,
http://www.list.org, but we have not put anything together for Spirit users yet. There are LOTS and LOTS of settings, and the Mailman interface has help documentation, but we have not made a guide yet or recommended standard configuration. Also a good source for information would be
http://www.foretec.com/python/workshops/1998-11/proceedings/papers/manheimer/manheimer.htmlFor now, you'll have to just go through all the pages and pages of settings to get what your want.
If you'd be interested in helping other users, you can document what you've learned about the settings and/or create user guidelines.
Thanxalot!
