# mkdir /var/tmp/{extman,extmail}                               //创建session目录
# chown vuser:vgroup /var/tmp/extma*
# mkdir -p /var/maildata/domains/extmail.org/postmaster/Maildir //创建邮件存储目录
# chown -R vuser:vgroup /var/maildata/
# mkdir -p /var/www/extsuite/{extmail,extman}                   //创建extmail和extman网页文件目录

安装extmail：

# tar zxvf extmail-1.2.tar.gz
# cp -rp extmail-1.2/* /var/www/extsuite/extmail/
# chmod -R 755 /var/www/extsuite/
# cd /var/www/extsuite/extmail/
# cp webmail.cf.default webmail.cf
# vi webmail.cf
SYS_SESS_DIR = /var/tmp/extmail/
SYS_MAILDIR_BASE = /var/maildata/domains/
SYS_USER_LANG = en_US
SYS_MYSQL_USER = extmail
SYS_MYSQL_PASS = extmail
SYS_MYSQL_DB = extmail
SYS_MYSQL_HOST = localhost
SYS_MYSQL_DB = extmail
SYS_MYSQL_TABLE = mailbox
SYS_MYSQL_ATTR_USERNAME = username
SYS_MYSQL_ATTR_DOMAIN = domain
SYS_MYSQL_ATTR_PASSWD = password
SYS_AUTHLIB_SOCKET = /usr/local/courier-authlib/var/spool/authdaemon/socket

安装extman：

# tar zxvf extman-1.1.tar.gz
# cp -rp extman-1.1/* /var/www/extsuite/extman/
# chown -R vuser:vgroup /var/www/extsuite/
# cd /var/www/extsuite/extman/
# cp webman.cf.default webman.cf
# vi webman.cf
SYS_CAPTCHA_ON = 0
SYS_MAILDIR_BASE = /var/maildata/domains/
SYS_SESS_DIR = /var/tmp/extman/

导入数据库：

# mysql  -u root -p < /var/www/extsuite/extman/docs/extmail.sql
# mysql  -u root -p < /var/www/extsuite/extman/docs/init.sql

生成extmail系统管理员的用户目录：

# cd /var/www/extsuite/extman/tools/
# ./maildirmake.pl /var/maildata/domains/extmail.org/postmaster/Maildir/
# chown -R vuser:vgroup /var/maildata/domains/
# cp -r /var/www/extsuite/extman/docs/mysql_virtual_* /etc/postfix/
# grep password /etc/postfix/mysql_virtual_*
mysql_virtual_alias_maps.cf:password = extmail
mysql_virtual_domains_maps.cf:password = extmail
mysql_virtual_limit_maps.cf:password = extmail
mysql_virtual_mailbox_maps.cf:password = extmail
mysql_virtual_sender_maps.cf:password = extmail

配置postfix支持虚拟域和虚拟用户：

# vi /etc/postfix/main.cf
##================ Virtual Mailbox Settings =====================#
virtual_mailbox_base = /var/maildata/domains
virtual_mailbox_maps =mysql:/etc/postfix/mysql_virtual_mailbox_maps.cf
virtual_mailbox_domains =mysql:/etc/postfix/mysql_virtual_domains_maps.cf
virtual_alias_domains =
virtual_alias_maps =mysql:/etc/postfix/mysql_virtual_alias_maps.cf
virtual_uid_maps = static:1000
virtual_gid_maps = static:1000
virtual_transport = virtual
maildrop_destination_recipient_limit = 1
maildrop_destination_concurrency_limit = 1

配置httpd虚拟主机：

# vi /etc/httpd/conf/httpd.conf
NameVirtualHost *:80
Include conf/vhost_*.conf
# vi /etc/httpd/conf/vhost_extmail.conf
# VirtualHost for ExtMail Solution
# VirtualHost for ExtMail Solution

        ServerName rhel5.vnimos.org
        DocumentRoot /var/www/extsuite/extmail/html/
        ScriptAlias /extmail/cgi/ /var/www/extsuite/extmail/cgi/
        Alias /extmail /var/www/extsuite/extmail/html/
        ScriptAlias /extman/cgi/ /var/www/extsuite/extman/cgi/
        Alias /extman /var/www/extsuite/extman/html/
# Suexec config
        SuexecUserGroup vuser vgroup

# chkconfig httpd on
# /etc/init.d/httpd start
