tar zxvf extmail-23-20060219.tar.gz
#cp -r extmail-0.23-20060219/ /usr/local/www/apache2/cgi-bin/extmail
创建配置文件

#cd /usr/local/www/cgi-bin/extmail/
#cp webmail.cf.default webmail.cf
修改配置文件,我只把需要修改的地方贴出来

# sys_config, the config file and webmail programe root

# sys_langdir, the i18n dir
SYS_LANGDIR = /usr/local/www/apache2/cgi-bin/extmail/lang

# sys_templdir, the template dir
SYS_TEMPLDIR = /usr/local/www/apache2/cgi-bin/extmail/html
# sys_netdisk_on, default is off
SYS_NETDISK_ON = 1
# maildir_base, the base dir of user maildir, use absolute path
# if not set.
SYS_MAILDIR_BASE = /home/data/domains
# if mysql, all relate paramters should prefix as SYS_MYSQL
SYS_MYSQL_USER = extmail
SYS_MYSQL_PASS = extmail
SYS_MYSQL_DB = extmail
SYS_MYSQL_HOST = localhost
SYS_MYSQL_SOCKET = /tmp/mysql.sock

3、安装extman
从extmail 官方网站下载软件包，解压复制到/usr/local/www/apache2/cgi-bin目录。

SYS_MYSQL_USER = webman
SYS_MYSQL_PASS = webman
SYS_MYSQL_DB = extmail
SYS_MYSQL_HOST = localhost
SYS_MYSQL_SOCKET = /tmp/mysql.sock

创建/tmp/extman
#mkdir /tmp/extman
