搭建Linux下郵件伺服器(extmail postfix clamav)

部分軟體簡介：
1、AMP －－－apache（web服務） 、mysql（資料庫）、php（非必需） 的簡稱
2、postfix －－mta 郵件系統核心
3、courier-authlib－－一個為courier-imap,maildrop,sasl2 提供用戶信息的後台進程序
4、courier-imap －－提供pop3,pop3s,imap,imaps 服務的程序
5、amavisd-new －－提供內容過濾
6、clamav －－ 著名的殺毒軟體
7、extmail －－一個著名的webmail程序
8、extman －－與extmail集成的後台管理程序

安裝環境：
centos 5.4
域名機器名：mail.uucun.lan
域名：uucun.lan

1、安裝AMP

[root@localhost ~]# yum -y install httpd httpd-devel mysql mysql-devel mysql-server php php-xml php-cli php-pdo php-mbstring php-mcrypt php-gd php-common php-devel php-mysql

修改啟動配置並啟動
[root@localhost ~]# chkconfig --level 345 mysqld on
[root@localhost ~]# chkconfig --level 345 httpd on
[root@localhost ~]# service mysqld start
[root@localhost ~]# service httpd start

2、導入extman 後台資料庫
[root@localhost ~]# tar zxf extman-0.2.5b1.tar.gz
[root@localhost ~]# cd extman-0.2.5b1/docs/
[root@localhost docs]# mysql -uroot -p <extmail.sql
Enter password:

[root@localhost mailgraph_ext]# /usr/local/mailgraph_ext/mailgraph-init start

Starting mail statistics grapher: mailgraph_ext

G、訪問extmail/extman
打開瀏覽器,輸入http://your_ip_address/extmail 注意：your_ip_address 為你實際的ip
第一個測試用戶為：postmaster 密碼：extmail 域：extmail

打開瀏覽器,輸入http://your_ip_address/extman
extman root 用戶為：root@extmail.org 密碼為：extmail*123*
注意：進入系統后要修改密碼及找回密碼的提示問題、答案.
