A "benchfile" is the book you leave in your desk drawer for your replacement in case you suddenly get a better job.
The Green Party of California rents a virtual private server (VPS) from Godmama's Forge. It's Ubuntu-9.0 ("Karmic Koala") based on Debian-5.0 ("Squeeze") plus some work-in-progress from Debian Unstable ("Sid"). The virtual host is named wangari.cagreens.org and runs under Vmware Enterprise.

apt-get install rsync
Backup is a nightly rsync via ssh to a host in Cameron's garage. Authentication is by a key in ~root/.ssh/authorized_keys.
DNS block list
apt-get install rbldnsd
The blocklist file is /var/lib/rbldns/iparanges. It's maintained on another server, and pushed here by rsync via ssh. Configuration is in /etc/default/rbldnsd. This is one of two servers of the "dnsbl.cagreens.org" blocklist. At least four hosts refer to this DNSBL.
Email server: Postfix and Mailman
The "Debian Way" has Postfix' configuration files in /etc/postfix and the mapfiles they use in /etc/postfix/maps. Tradition has the email aliases file in /etc/, so we have a symlink there pointing at the real one.
apt-get install postfix postfix-pcre mailman
Mailman runs as the "list" user. GNU Mailman installs into its data directories and runs there. Debian installs the software in /usr/lib/cgi-bin/mailman and /usr/lib/mailman/, with data files in /var/lib/mailman/. They've done a nice job of separating the files their package maintainer updates from those Mailman updates as it runs, so you can do
apt-get install mailman
when there's an update, without losing/breaking anything.
Mailman generates two files /var/lib/mailman/data/aliases and /var/lib/mailman/data/aliases.db which are nentioned in /etc/postfix/main.cf. That's where the aliases for Mailman posting and admin functions are.
There's a popular script for further integration between Postfix and Mailman. Debian distributes it with Mailman but we're not using it. It makes Postfix depend on Python. The main advantage would be pre-queue rejection of rejectable messages, reducing backscatter and administrative noise.
