经过两天的钻研，openwebmail终于被我安装成功，因为它确实是“复杂”配置的一套软件。下面是我的安装过程记录，首先你不要被大量的文字吓倒。经过安装总结后才发现，其实不是很难！
安装环境：Centos linux 2.6.18-164.15.1.el5 
已经安装好apache2(httpd 2.2.3-43) 与postfix 2.6.18-164.15.1及perl  5.8.8
假如你还未安装以上组建，必须先下载安装：
yum install httpd  postfix  perl
ok后我们开始进行openwebmail的实际安装过程：

第一步：
到http://www.openwebmail.org/openwebmail/download/处下载如下文件包：
openwebmail-2.53.tar.gz
1 CGI.pm-3.05.tar.gz     
2 Text-Iconv-1.2.tar.gz
3 Digest-1.08.tar.gz     
4 libiconv-1.9.1.tar.gz (非必须）   
5 libnet-1.19.tar.gz
6 Digest-MD5-2.33.tar.gz 
7 MIME-Base64-3.01.tar.gz

第二步：
分别对于他们进行编译安装：

[root@linux CGI.pm-3.05]# perl Makefile.PL
Checking if your kit is complete...

Ah, I see you already have installed libnet before.

Do you want to modify/update your configuration (y|n) ? [no] no
这里提示要不要对原有网络配置进行更新修改，我们选择no
This script will prompt you to enter hostnames that can be used as
defaults for some of the modules in the libnet distribution.

To ensure that you do not enter an invalid hostname, I can perform a
lookup on each hostname you enter. If your internet connection is via
a dialup line then you may not want me to perform these lookups, as
it will require you to be on-line.

Do you want me to perform hostname lookups (y|n) ? [yes]

The following questions all require a list of host names, separated
with spaces. If you do not have a host available for any of the
services, then enter a single space, followed by . To accept the
default, hit
