Mailman
Some tips on using mailman
I am using the standard Ubuntu package. This means things are symlinked from the normal places in /var to where they are really installed in /usr
User.group = list.list not the usual mailman.mailman
Various config files including mm_cfg.py are in /etc/mailman I am using postfix as the MTA
Pipermail is installed
master.cf has this /usr/lib/mailman/bin/postfix-to-mailman.py
Notes in mailman docs
Integrating Postfix with Mailman
Create a list

Move a list from a different server
Spam control
I am using postgrey (installed from Ubuntu package).
Home page http://postgrey.schweikert.ch/
See http://www.howtoforge.com/greylisting_postfix_postgrey
Postgrey simply sends a message back on first connection refusing email and saying "come back later". It then creates a database (whitelist) entry and if the server connects to try again, lets it through.
You can whitelist or blacklist anyone manually.
/etc/postgrey/whitelist_clients /etc/postgrey/whitelist_recipients
Local (internal) mail is unaffected.
You can monitor the lists
