第十六节：安装SpamAssassin
Spam是一个让人讨厌的字眼. 大部分的人都不喜欢它. 如果你想保护自己免受spam, 你就需要安装SpamAssassin.
因我在安装系统的时候已经选择好了SpamAssassin。现在我们将其升级到最新版：
cd /home/pkg
rpm -Uvh spamassassin-3.0.2-2.1.el3.rf.i386.rpm
还需要安装另外一个软件包：
rpm -Uvh perl-Razor-Agent-2.40-2.i386.rpm
＃修改起动脚本使spamassassin支持vpopmail
#修改如下一行：
vi /etc/init.d/spamassassin
SPAMDOPTIONS="-d -c -m5 -H -x -u spamd -v"
vi /etc/sysconfig/spamassassin
SPAMDOPTIONS="-d -c -m5 -H -x -u spamd -v"
下图是我在安装SpamAssassin时所列出的perl模块,SpamAssassin所要用到的一些Perl模块是：
perl-Time-HiRes
perl-Digest-SHA1
perl-HTML-Parser
perl-DB_File
perl-HTML-Tagset
perl-Razor-Agent
perl-DBI
perl-Net-DNS
perl-URI
这些模块请安装上。
#spamassassin的过滤模板在/etc/mail/spamassassin/local.cf,修改为：
vi /etc/mail/spamassassin/local.cf
