clamav + clamsmtpd + postfix

Dodajemy usera i grupę clamav:

pw group add clamav -g 106
pw user add clamav -c “ClamAVUser” -d “/nonexistent” -s “/sbin/nologin” -u 106 -g 106

Sciagamy źrodła, rozpakowujemy, configure+opcje (np. –prefix=/usr/local, generalnie polecam odpalic z –help), make, make install

Tworzymy katalog na sygnatury i ustawiamy prawa:

mkdir -p /var/lib/clamav
chown clamav:clamav /var/lib/clamav

Dostosowujemy zawartość plików /usr/local/etc/clamd.conf i /usr/local/etc/freshclam.conf, odpalamy z reki + dopisujemy do skryptów startowych.

Uruchamiam calość:

/usr/local/bin/freshclam –config-file=/usr/local/etc/freshclam.conf -d

/usr/local/sbin/clamd -c /usr/local/etc/clamd.conf

Ściągamy clamsmtpd,

http://memberwebs.com/stef/software/clamsmtp/clamsmtp-1.10.tar.gz

./configure –prefix=/usr/local
make
make install

Edytujemy /usr/local/etc/clamsmtpd.conf

/usr/local/sbin/clamsmtpd -f /usr/local/etc/clamsmtpd.conf -p /var/run/clamav/clamsmtpd.pid

Zmieniamy main.conf i master.cf, restartujemy postfix’a

Pliki konfiguracyjne postfix’a, clamd, clamsmtpd i freshclam’a:

W main.cf na końcu dodajemy linijkę:

content_filter = scan:[127.0.0.1]:10025

Zawartość master.cf:
