安装-配置SpamAssassin

1、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

 

2、手动安装

[root@linuxas3 src]# cd Mail-SpamAssassin-2.63
[root@linuxas3 Mail-SpamAssassin-2.63]# export LC_ALL=C
[root@linuxas3 Mail-SpamAssassin-2.63]# perl Makefile.PL
[root@linuxas3 Mail-SpamAssassin-2.63]# make 
[root@linuxas3 Mail-SpamAssassin-2.63]# make test
[root@linuxas3 Mail-SpamAssassin-2.63]# make install (as root) 

3、自动安装

[root@linuxas3 src]# perl -MCPAN -e shell
cpan> install Mail::SpamAssassin
default text: [the administrator of that system]

chmod 755 /usr/share/spamassassin
  /usr/bin/make install  -- OK

cpan>

 

#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。
