安装 openwebmail
yum install openwebmail
cd /etc/yum.repos.d
ls
wget -q http://openwebmail.org/openwebmail/download/redhat/rpm/release/openwebmail.repo
yum install openwebmail
ls

yum install openwebmail
rpm -qa |grep openwebmail
openwebmail-2.53-6.el6.noarch
openwebmail-data-2.53-6.el6.noarch
8. 安装webmin (必须先安装好samba,dovecot,postfix,openwebmail 再安装webmin，否则网页管理不了这些软件的功能)
rpm -ivh webmin-1.791-1.noarch.rpm
less /etc/webmin/miniserv.conf 禁用SSL ssl=0
9.初始化OPENWEBMAIL
/var/www/cgi-bin/openwebmail/openwebmail-tool.pl --init
netstat -lnt
less /var/log/maillog
service postfix restart
less /var/log/maillog
10. postfix postmap 创建域名文件
less /etc/postfix/local_domains｛
factory.tgtex.com ok
mail.factory.tgtex.com ok
｝
postmap hash:/etc/postfix/local_domains
修改：postfix配置-一般选项：
接受邮件的域：$myhostname, localhost.$mydomain, localhost, $mydomain,factory.tgtex.com,office.tgtex.com
此邮件系统的因特网主机名：mail.factory.tgtex.com
本地因特网域名：factory.tgtex.com
本地网络：127.0.0.0/8,192.168.0.0/22
11. 修改less /etc/dovecot/conf.d/10-mail.conf 邮箱目录参数
mail_location = mbox:~/mail:INBOX=/var/spool/mail/%u
在网页中修改：dovecot的协议支持选项imap,pop3,lmtp，
用户验证方式：
Password authentication source:Unix passwd file
Authentication methods:Plain-text
12. apache服务器的 默认服务器 的 目录索引
目录索引文件：/cgi-bin/openwebmail/openwebmail.pl
13.

useradd -M dovenull -s /sbin/nologin -g dovenull
groupadd dovecot
useradd -M dovecot -s /sbin/nologin -g dovecot
14. 修改OPENWEBMAIL首页下面的文字模板
less /var/www/cgi-bin/openwebmail/etc/openwebmail.conf
<page_footer>
Tianjin Tiange Mail System

网页写信的默认语言

default_style Default
default_iconset Cool3D.Chinese.Simplified
15.WEBMIN 网络--网络配置--DNS客户--解析顺序hosts file,DNS
这个选项只要本机的hostname正常，就能收发邮件。
设置CENTOS的网关后，必须能访问外网，否则：邮件客户端发送邮件等待15秒左右，VSFTPD的FTP登陆也受影响。或者不设置网关，就不存在这个问题了
