Configuring spamass-milter

this is obsolete doc -- see http://doc.nethence.com/ instead

On FreeBSD 8

Install spamd and spamass-milter,

cd /usr/ports/www/p5-HTML-Parser/

make reinstall clean

cd /usr/ports/converters/p5-Encode-Locale/

make reinstall clean

cd ~/

echo $PACKAGESITE

pkg_add -r spamass-milter spamass-rules p5-Mail-SpamAssassin

ref. Spamassassin : Can't locate HTML/Parser.pm in @INC: http://help.directadmin.com/item.php?id=38

check that everything went fine,

grep spam /etc/group

grep spam /etc/passwd

ls -ld /var/spool/spamd

pkg_info | grep -E 'spamass-milter|spamass-rules|p5-Mail-SpamAssassin|p5-HTML-Parser|p5-Encode-Locale' | awk '{print $1}'

and update the rules right now,

sa-update -v

Configure the thing (default 5.0),

cd /etc/mail/

ln -s /usr/local/etc/mail/spamassassin

cd /etc/mail/spamassassin/

cat > local.cf <<EOF9

required_score 4.5

remove_header ham Status

remove_header ham Level

use_bayes 1

bayes_auto_learn 1

bayes_path /var/spool/spamd/.spamassassin/bayes

bayes_file_mode 0777

EOF9

Eventually further configure the thing,

cd /etc/mail/spamassassin/

vi init.pre

Enable the spam daemon at boot time,

cd /etc/rc.d/

cp /usr/local/etc/rc.d/sa-spamd ./

cp /usr/local/etc/rc.d/spamass-milter ./

cat >> rc.conf <<EOF9

spamd_enable="YES"

spamd_flags="-u spamd -H /var/spool/spamd"

spamass_milter_enable="YES"

EOF9

and start it,

/etc/rc.d/sa-spamd restart

/etc/rc.d/spamass-milter restart

ls -l /var/run/spamass-milter.sock

Why not add a daily spamassassin update to your root crontab,

crontab -e

add,

0 3 * * * /usr/local/bin/sa-update

note. or specifically on freebsd (both do work),

vi /etc/crontab

add,

0 3 * * * root /usr/local/bin/sa-update

Finally add this to your sendmail macro,

cd /etc/mail/

vi $HOSTNAME.mc

INPUT_MAIL_FILTER(`spamassassin', `S=local:/var/run/spamass-milter.sock, F=, T=C:15m;S:4m;R:4m;E:10m')dnl

define(`confMILTER_MACROS_CONNECT',`b, j, _, {daemon_name}, {if_name}, {if_addr}')dnl

define(`confINPUT_MAIL_FILTERS', `spamassassin')

apply and restart sendmail,

make

make install

/etc/rc.d/sendmail restart

now verify that spamass-milter is working by sending a message to yourself,

echo "Testing spamass-milter..." | mail -s"Spam test" root

and check the headers,

X-Spam-Status: No, ...

Note. if you are using postoffice smtp instead of sendmail see http://pbraun.nethence.com/doc/mail/postoffice.html

On RHEL 5/6

Makes sure those packages are installed,

rpm -q sendmail-milter spamassassin

Note. even if you don't use sendmail for your milters, you'll need libmilter with it.

Download and install spamass-milter from EPEL,

#wget http://download.fedora.redhat.com/pub/epel/5/i386/spamass-milter-0.3.1-19.el5.i386.rpm

#rpm -ivh spamass-milter-0.3.1-19.el5.i386.rpm

#wget http://dl.fedoraproject.org/pub/epel/6/x86_64/spamass-milter-0.3.2-3.el6.x86_64.rpm

#rpm -ivh spamass-milter-0.3.2-3.el6.x86_64.rpm

wget http://dl.fedoraproject.org/pub/epel/6/i386/spamass-milter-0.3.2-3.el6.i686.rpm

rpm -ivh spamass-milter-0.3.2-3.el6.i686.rpm

Note. the package includes the spamass-milter user, init script and folder for the unix socket,

grep ^sa-milt /etc/passwd

ls -l /etc/init.d/spamass-milter

ls -ld /var/run/spamass-milter/

Tune the thing a little bit,

cd /etc/sysconfig/

cat > spamass-milter <<EOF9

EXTRA_FLAGS="-m -r 8 -i 127.0.0.1"

EOF9

Note. -m to disable modification of the message (speeds up)

Note. -r to reject tagged >= number

Note. -i to let messages pass through from specific networks

Note. DO NOT -f to fork into the background, RHEL/EPEL's init script ALREADY daemonizes the thing (it would restart in loop)

Note. RUN_AS_USER is already defined in the init script.

Start and enable the daemons at boot

service spamassassin restart

service spamass-milter restart

chkconfig spamassassin on

chkconfig spamass-milter on

#pkill postoffice

#/usr/local/lib/postoffice -bd -q5

Check the daemon runs with the previously defined options,

ps aux | grep spamass-milter

and check for the socket,

ls -l /var/run/spamass-milter/spamass-milter.sock

Configure sendmail -- see FreeBSD conf above -- or postoffice smtp -- see http://pbraun.nethence.com/doc/mail/postoffice.html
