這里我們只講SpamAssassin的簡(jiǎn)單應(yīng)用，就是利用SpamAssassin的規(guī)則集把垃圾郵件標(biāo)注為垃圾郵件，然后在客戶(hù)端outlook用策略把帶有垃圾郵件字符的郵件自動(dòng)轉(zhuǎn)移到垃圾郵件目錄。
參看文章
CCERT中文垃圾郵件過(guò)濾規(guī)則集
(http://www.ccert.edu.cn/spam/sa/Chinese_rules.htm)
試驗(yàn)環(huán)境：redhat9.0
前提條件：已經(jīng)安裝好qmail，本文已經(jīng)搭建的環(huán)境是qmail+vpopmail+igeus
1：安裝SpamAssassin
安裝方法1：直接通過(guò)CPAN安裝
perl -MCPAN -e shell
install Mail::SpamAssassin
2：自己編譯安裝
去http://spamassassin.apache.org下載最新版本的軟件
解壓后：# perl Makefile.PL
# make
# make install
# 進(jìn)行一個(gè)spam和non-spam的測(cè)試
在spamassassin源文件目錄:
spamassassin -t < sample-spam.txt > spamtest.txt
less spamtest.txt
spamassassin -t < sample-nonspam.txt > nospamtest.txt
less nospamtest.txt
spamtest.txt文件在主題一段中將包含"*****SPAM*****" 這一行, 而nospamtest.txt文件中則沒(méi)有.
(默認(rèn)讀取/etc/mail/spamassassin/local.cf配置.)
如果make過(guò)程中報(bào)錯(cuò)，可以參看此文解決相關(guān)問(wèn)題http://blog.5ilinux.com/archives/2005/07/spamassassin.html
3：配置local.cf文件
# vi /etc/mail/spamassassin/local.cf
# How many hits before a message is considered spam.
required_hits 9.5
# Text to prepend to subject if rewrite_subject is used
rewrite_header Subject *****垃圾郵件*****
# Encapsulate spam in an attachment
report_safe 1
# Enable the Bayes system
use_bayes 1
# Enable Bayes auto-learning
bayes_auto_learn 1
# Enable or disable network checks
skip_rbl_checks 1
use_razor2 0
use_dcc 0
use_pyzor 0
# Mail using languages used in these country codes will not be marked
# as being possibly spam in a foreign language.
ok_languages all
# Mail using locales used in these country codes will not be marked
# as being possibly spam in a foreign language.
ok_locales all
關(guān)于SpamAssassin的配置文件，可參考SpamAssassin 3.x 配置指南（中文版）
(http://anti-spam.org.cn/references/index.php?Action=Show&ID=9)
4：下載垃圾郵件中文規(guī)則集
wget -N -P /usr/share/spamassassin www.ccert.edu.cn/spam/sa/Chinese_rules.cf
5：qmail和SpamAssassin的結(jié)合
在SpamAssassin 3.x 的spamc 目錄下編譯qmail-spamc
# cc -O -o qmail-spamc qmail-spamc.c
# install -m 755 qmail-spamc /var/qmail/bin
# ln -s /var/qmail/bin/qmail-queue /usr/bin/qmail-queue
編輯 /etc/tcp.smtp 如下
127.:allow,RELAYCLIENT=""
:allow,QMAILQUEUE="/var/qmail/bin/qmail-spamc"
然后：
tcprules tcp.smtp.cdb tcp.smtp.tmp < tcp.smtp
在編譯目錄spamd目錄下
mv redhat-rc-script.sh /etc/rc.d/init.d/spamd
啟動(dòng)spamd
/etc/rc.d/init.d/spamd start
這樣SpamAssassin會(huì)根據(jù)規(guī)則集自動(dòng)判斷垃圾郵件，把認(rèn)為潛在可能的垃圾郵件打上****垃圾郵件****的標(biāo)，一目了然，至于客戶(hù)端outlook怎么設(shè)置策略自動(dòng)轉(zhuǎn)移垃圾郵件，就不用我說(shuō)了吧。
