3，安装 dovecot
yum -y install dovecot
修改/etc/dovecot.conf
添加一行
procotol = pop3
启动dovecot 服务
service dovecot start
4。安装openwebmail
perl-Text-Iconv 这个包源里面没有，但官网的其它directory 里面有，直接rpm 安装
首先配置openwebmail 的yum 源MIMEdefang
rpm -ivh
http://openwebmail.org/openwebma ... -1.7-2.el5.i386.rpm
# cd /etc/yum.repos.d
# lftpget
http://openwebmail.org/openwebma ... se/openwebmail.repo
If SELinux enabled, you may need to set it 'permissive' in
/etc/sysconfig/selinux or system-config-selinux

Permission and Ownership for openwebmail files have been fixed!
Please execute following tool first as a root:
/var/www/cgi-bin/openwebmail/openwebmail-tool.pl --init
After restarting httpd service, login with non-root account from
http://localhost.localdomain/cgi-bin/openwebmail/openwebmail.pl
or
http://localhost.localdomain/webmail
/var/www/cgi-bin/openwebmail/openwebmail-tool.pl --init 进行配置，直接回车就可以了
http://youservername/cgi-bin/openwebmail/openwebmail.pl
##如果安装不成功，直接到官网下载。再安装也是一样的效果，新版本的OPENWEBMAIL真的是比较智能化，配置也简单多了。语言支持也非常不错！对于 语言要求比较高的公司也是个不错的选择。而且采用是CGI模式，相对来说，蛮快的。上面几个依赖的包也是CGI的加速软件。看以后能不能再加上 fastcgi模块来优化一下(小弟对这些不是太懂)
安装apace
yum -y install httpd
然后配置apache
允许CGI执行
配置以下两项
ScriptAlias /cgi-bin/ "/var/www/cgi-bin/"
#
# "/var/www/cgi-bin" should be changed to whatever your ScriptAliased
# CGI directory exists, if you have that configured.
#
<Directory "/var/www/cgi-bin">
AllowOverride None
Options ExecCGI ##原有的是Opentions None 改成我前面写的Options ExecCGI 这个意思是允许执行CGI类型的文件
Order allow,deny
Allow from all
</Directory>
找到这一行，把前面的#号去掉并且加上支持.pl文件类型
# To use CGI scripts outside of ScriptAliased directories:
# (You will also need to add "ExecCGI" to the "Options" directive.)
#
AddHandler cgi-script .cgi .pl ####在这一行添加对.pl文件类型的支持。因为我们的openwebmail是perl 语言编写的。而且我们的openwebmail文件后缀名为pl.把以最好加上 .pl。这样不容易出错！
===========================================================
配置openwebmail 可以被 clamav扫描
# vi openwebmail.conf
enable_viruscheck yes
viruscheck_pipe /usr/bin/clamdscan --mbox --disable-summary --stdout -
viruscheck_source_allowed all
####这是官方的howto文档。我是直接抄过来的。MS没有啥效果！大家有兴趣可以自己研究
4，安装spamassassin (mimedefang 为调用spamassassin来防垃圾邮件)
yum -y install spamassassin
配置spamassassin
2.编辑主配置文件/etc/mail/spamassassin/local.cf
required_hits 10.0
rewrite_subject 1
required_score 5.0
rewrite_header Subject *****SPAM*****
report_safe 1
use_bayes 1
bayes_auto_learn 1
skip_rbl_checks 1
use_razor2 0
use_pyzor 0
ok_locales all
#service spamassassin start
spamassassin 报错
如果出现 /var/log/maillog 报错
spamd[850]: rules: meta test DIGEST_MULTIPLE has undefined dependency 'DCC_CHECK'
vi /etc/mail/spamassassin/v310.pre
去掉下面的注释符号# 不然服务会启动后，不能和mimedefang结合使用
loadplugin Mail::SpamAssassin: lugin: CC
如果要更强的防垃圾邮件规则，大家可以到网上找找相关的规则 ！
安装chinese_rules.cf
下载文件: wget -N -P /usr/share/spamassassin/
www.ccert.edu.cn/spam/sa/Chinese_rules.cf
/etc/init.d/init-script restart
可以把这个放到crontab 里面，定时更新防垃圾规则，规则要量力而行，生产环境要经过测试，最好不要挡住正常邮件
以下是网上的规则，最好经过测试再用
--------------------------------------------------------------------------
Jul 18 18:53:41 huzi sendmail[4592]: m6IArbo3004592: Milter delete (noop): header: X-Spam-Score (正常结合mimedefang使用了)

Jul 18 18:53:41 huzi sendmail[4595]: m6IArbo3004592: to=<
huzi@huzi.uplookinghuzi.com>, ctladdr=<
root@huzi.uplookinghuzi.com> (0/0), delay=00:00:04, xdelay=00:00:00, mailer=local, pri=30623, dsn=2.0.0, stat=Sent
-------------------------------------------------------------------------------
下面是网上的一个防垃圾邮件的规则。大家看着用吧。用前先测试 ！
为了尽量减少误判，建议使用SpamAssassin提供的白名单功能。比如在/etc/mail/SpamAssassin/sa-mimedefang.cf中添加
whitelist_from *@cernet.edu.cn
会使所有来自cernet.edu.cn的邮件被视为正常邮件。
SpamAssassin 主要配置文件是 /etc/mail/spamassassin/local.cf和 /usr/share/spamassassin/*.cf，后者是默认的规则文件集，一般不要改动；前者可以让管理员修改配置添加规则。由于默认的规则 库不太符合国内中文邮件，所以你得添加一些适合中文的规则到local.cf文件中，下面的是由反垃圾邮件联盟网站ten提供的适合中文邮件规则集:

鉴于相当多的网友询问如何在Spamassassin里配置CBL的黑名单作为其评分标准之一，
故整理了一下CBL/CDL/CBL+/CBL-的在Spamassassin里的配置格式，
其中有些设置了检查返验证码，有些没设，以及分值的设定等等，这些可根据各自的实际情况设置。
其中我们推荐优先使用CBL-和CML。

#最佳推荐之使用CBL-#
