安装CENTOS 6.5 32位（CentOS-6.5-i386）+postfix+dovecot+openwebmail passwd验证的邮件系统
安装CENTOS 6.5 32位（CentOS-6.5-i386）+postfix+dovecot+openwebmail passwd验证的邮件系统。[*]安装服务器分区：/BOOT分区至少200M,swap分区物理内存的1-2倍，分配/home /var目录到另1块硬盘，分配启动硬盘剩余的容量到/分区
[*]选择服务器平台的模式，在组件中分别选择好编辑环境，gnome窗口模式，samba,vsftpd
[*]禁用防火墙，Selinux模式disable /etc/selinux/config SELINUX=disabled
[*]设置网络 外网环境
[*]安装VNC server

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SSLssl=09.初始化OPENWEBMAIL/var/www/cgi-bin/openwebmail/openwebmail-tool.pl --initnetstat -lntless /var/log/maillog service postfix restartless /var/log/maillog 10. postfix postmap 创建域名文件less /etc/postfix/local_domains｛factory.tgtex.com okmail.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 fileAuthentication 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.groupadd dovenulluseradd -M dovenull -s /sbin/nologin -g dovenullgroupadd dovecotuseradd -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
</page_footer>
网页写信的默认语言# Display Preference
default_style Default
default_iconset Cool3D.Chinese.Simplified
/var/www/cgi-bin/openwebmail/etc/defaults/openwebmail.confwebdisk_uploadlimit 50000控制网络磁盘上传附件的大小
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
16. 邮件服务器切换的时候
更改服务器的IP,更改/etc/hosts 主机名，重启网络即可
控制接收域的邮件是在/etc/postfix/main.cf 中
mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain,factory.tgtex.com,office.tgtex.com
邮件服务器的DNS记录 增加MX
好资源，必须支持楼主。
