5.3.5 Mailman Scripts
The installation of Mailman sets up a group of crontab entries, host definitions, and alias
definitions that are used by the package. The site-wide password needs to be set using the
mmsitepass script:
# su - mailman
$ bin/mmsitepass newpass
The Mailman environment can be started and stopped by the following commands.
To start Mailman:
/usr/internet/mailman/scripts/mailman start
To stop Mailman:
/usr/internet/mailman/scripts/mailman stop
Mailman is started by default at system boot time.

The log information related to subscription, error, post or sendmail can be accessed in the directory
/usr/internet/mailman/log.
5.4 Bogofilter Spam Filter
Bogofilter is a Bayesian spam filter. In its normal mode of operation, it takes an email message
or other text on standard input, does a statistical check against lists of good and bad words, and
returns a status code indicating whether or not the message is spam. Bogofilter is designed with
a fast algorithm, uses the Berkeley DB for fast startup and lookups, is coded directly in C, and
is tuned for speed, so it can be used for production by sites that process a lot of mail.
The bogofilter related commands are part of the sendmail setld subset (IAESMTP). If this subset
is installed, the various bogofilter user level commands (bogofilter, bogolexer,
bogoupgrade, and bogoutil) have been installed. The commands are located in the
/usr/local/bin directory.
bogofilter(1) - Fast Bayesian spam filter
bogolexer(1) - Utility program for separating email messages into tokens
bogoupgrade(1) - Upgrades bogofilter database to current version
bogoutil(1) - Dumps, loads, and maintains bogofilter database files
5.4.1 Training Bogofilter
Bogofilter must be trained before it can be used as a spam filter mechanism. Users must start by
saving their delivered e-mail into two groups: spam e-mail messages and valid e-mail messages.
The saved group of spam messages is first fed to bogofilter for registration. As each message is
read, bogofilter breaks down the message into word tokens, and uses this input to score and
then populate its database, marking each item as spam related. The following command is used
to register a set of spam messages collected in mbox:
$ bogofilter -s -M mbox # spam messages
