部分修改选项的说明：

SYS_MESSAGE_SIZE_LIMIT = 5242880
用户可以发送的最大邮件

SYS_USER_LANG = en_US
语言选项，可改作：
SYS_USER_LANG = zh_CN

SYS_MAILDIR_BASE = /home/domains
此处即为您在前文所设置的用户邮件的存放目录，可改作：
SYS_MAILDIR_BASE = /var/mailbox

SYS_MYSQL_USER = db_user
SYS_MYSQL_PASS = db_pass
以上两句句用来设置连接数据库服务器所使用用户名、密码和邮件服务器用到的数据库，这里修改为：
SYS_MYSQL_USER = extmail
SYS_MYSQL_PASS = extmail

SYS_MYSQL_HOST = localhost
指明数据库服务器主机名，这里默认即可

SYS_MYSQL_TABLE = mailbox
SYS_MYSQL_ATTR_USERNAME = username
SYS_MYSQL_ATTR_DOMAIN = domain
SYS_MYSQL_ATTR_PASSWD = password

以上用来指定验正用户登录里所用到的表，以及用户名、域名和用户密码分别对应的表中列的名称；这里默认即可

SYS_AUTHLIB_SOCKET = /var/spool/authdaemon/socket
此句用来指明authdaemo socket文件的位置，这里修改为：
SYS_AUTHLIB_SOCKET = /usr/local/courier-authlib/var/spool/authdaemon/socket

# vim /etc/httpd/conf/httpd.conf

SYS_MAILDIR_BASE = /home/domains
此处即为您在前文所设置的用户邮件的存放目录，可改作：
SYS_MAILDIR_BASE = /var/mailbox

SYS_DEFAULT_UID = 1000
SYS_DEFAULT_GID = 1000
此两处后面设定的ID号需更改为前而创建的postfix用户和postfix组的id号，本文使用的是2525，因此，上述两项需要修改为：
SYS_DEFAULT_UID = 2525
SYS_DEFAULT_GID = 2525

修改
SYS_CAPTCHA_ON = 1
为
SYS_CAPTCHA_ON = 0  ###这样在登录时就没有验证码了。在实际最好不要这做。
