6）配置postfix支持虚拟用户
[root@node1 courier-authlib-0.66.1]# vi /etc/postfix/main.cf
virtual_mailbox_base = /var/mailbox
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:2525
virtual_gid_maps = static:2525
virtual_transport = virtual
——安装Extmail
1）创建相关目录并解压extmail
[root@node1 soft]# mkdir -p /var/www/extsuite
[root@node1 soft]# tar fzvx extmail-1.2.tar.gz -C /var/www/extsuite/
[root@node1 soft]# cp /var/www/extsuite/extmail-1.2 /var/www/extsuite/extmail
[root@node1 soft]# cd /var/www/extsuite/extmail
2）修改Extmail的主配置文件
[root@node1 extmail]# cp webmail.cf.default webmail.cf
[root@node1 extmail]# vi webmail.cf
SYS_SESS_DIR = /tmp/extmail
SYS_UPLOAD_TMPDIR = /tmp/extmail/upload
SYS_USER_LANG = zh_CN
SYS_MIN_PASS_LEN = 8
SYS_MAILDIR_BASE = /var/mailbox
SYS_MYSQL_USER = extmail
SYS_MYSQL_PASS = extmail
SYS_MYSQL_DB = extmail
SYS_MYSQL_HOST = localhost
SYS_MYSQL_SOCKET = /var/lib/mysql/mysql.sock
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
3）建立extmail的临时文件目录及session目录
[root@node1 extman]# mkdir -p /tmp/extmail/upload
[root@node1 extman]# chown postfix.postfix -R /tmp/extmail/
——安装Extman
1）解压extmail
[root@node1 soft]# tar fzvx extman-1.1.tar.gz -C /var/www/extsuite/
[root@node1 soft]# cd /var/www/extsuite/extmail
[root@node1 extsuite]# mv extman-1.1 extman
[root@node1 extsuite]# cd extman
2）修改Extman的主配置文件
[root@node1 extman]# cp webman.cf.default webman.cf
[root@node1 extman]# vi webman.cf
SYS_MAILDIR_BASE = /var/mailbox
SYS_DEFAULT_UID = 2525
SYS_DEFAULT_GID = 2525
SYS_MYSQL_USER = extmail
SYS_MYSQL_PASS = extmail
SYS_MYSQL_DB = extmail
SYS_MYSQL_HOST = localhost
SYS_MYSQL_SOCKET = /var/lib/mysql/mysql.sock
3）修改cgi目录的属主
[root@node1 extman]# chown -R postfix.postfix /var/www/extsuite/extman/cgi/
[root@node1 extman]# chown -R postfix.postfix /var/www/extsuite/extmail/cgi/
4）导入Extman的数据库
[root@node1 extman]# cd docs/
[root@node1 docs]# vi extmail.sql
将文件里面所有的TYPE=MyISAM改为ENGINE=MyISAM、命令如下：
:% s/TYPE/ENGINE/g 共有5处
[root@node1 docs]# sed -i 's/extmail.org/test.com/g' init.sql
[root@node1 docs]# sed -i 's/1000/2525/g' init.sql
[root@node1 docs]# mysql -u root < extmail.sql
[root@node1 docs]# mysql -u root < init.sql
5）授予用户extmail访问extmail数据库的权限
[root@node1 ~]# mysql -uroot -p
Enter password:

mysql> quit
Bye
6）为Extman创建临时目录并给予权限
[root@node1 docs]# mkdir /tmp/extman
[root@node1 docs]# chown postfix.postfix -R /tmp/extman/
——重启postfix、dovecot、saslauthd、nginx
[root@node1 docs]# service postfix restart
[root@node1 docs]# service dovecot restart
[root@node1 docs]# service saslauthd restart
——测试虚拟用户实现结果
1）测试Postfix 支持虚拟用户
[root@node1 docs]# /usr/local/courier-authlib/sbin/authtest -s login postmaster@test.com extmail
Authentication succeeded. // 表示成功
Authenticated: postmaster@test.com (uid 2525, gid 2525)
Home Directory: /mailbox/test.com/postmaster
Maildir: /mailbox/test.com/postmaster/Maildir/
Quota: (none)
Encrypted Password: $1$phz1mRrj$3ok6BjeaoJYWDBsEPZb5C0
Cleartext Password: extmail
Options: (none)
2）测试虚拟用户SMPT发信认证
[root@node1 docs]# printf "postmaster@test.com" | openssl base64
cG9zdG1hc3RlckBleHRtYWlsLm9yZw==
[root@node1 docs]# printf "extmail" | openssl base64
