# 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.cfSYS_SESS_DIR = /var/tmp/extmail/SYS_MAILDIR_BASE = /var/maildata/domains/SYS_USER_LANG = en_USSYS_MYSQL_USER = extmailSYS_MYSQL_PASS = extmailSYS_MYSQL_DB = extmailSYS_MYSQL_HOST = localhostSYS_MYSQL_DB = extmailSYS_MYSQL_TABLE = mailboxSYS_MYSQL_ATTR_USERNAME = usernameSYS_MYSQL_ATTR_DOMAIN = domainSYS_MYSQL_ATTR_PASSWD = passwordSYS_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.cfSYS_CAPTCHA_ON = 0SYS_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 = extmailmysql_virtual_domains_maps.cf:password = extmailmysql_virtual_limit_maps.cf:password = extmailmysql_virtual_mailbox_maps.cf:password = extmailmysql_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/domainsvirtual_mailbox_maps =mysql:/etc/postfix/mysql_virtual_mailbox_maps.cfvirtual_mailbox_domains =mysql:/etc/postfix/mysql_virtual_domains_maps.cfvirtual_alias_domains =virtual_alias_maps =mysql:/etc/postfix/mysql_virtual_alias_maps.cfvirtual_uid_maps = static:1000virtual_gid_maps = static:1000virtual_transport = virtualmaildrop_destination_recipient_limit = 1maildrop_destination_concurrency_limit = 1

配置httpd虚拟主机：

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

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

配置图形化日志 Mailgraph_ext：
