五、配置courier-authlib [ExtMail Project]

1、安装Courier-Authlib

安装以下软件包:

shell

# yum install courier-authlib
# yum install courier-authlib-mysql

编辑/etc/authlib/authmysqlrc文件:

shell

# vi /etc/authlib/authmysqlrc

并将其内容清空，然后增加如下内容:

MYSQL_SERVER            localhost
MYSQL_USERNAME          extmail
MYSQL_PASSWORD          extmail
MYSQL_SOCKET            /var/lib/mysql/mysql.sock
MYSQL_PORT              3306
MYSQL_OPT               0
MYSQL_DATABASE          extmail
MYSQL_USER_TABLE        mailbox
MYSQL_CRYPT_PWFIELD     password
MYSQL_UID_FIELD         uidnumber
MYSQL_GID_FIELD         gidnumber
MYSQL_LOGIN_FIELD       username
MYSQL_HOME_FIELD        homedir
MYSQL_NAME_FIELD        name
MYSQL_MAILDIR_FIELD     maildir
MYSQL_QUOTA_FIELD       quota
MYSQL_SELECT_CLAUSE     SELECT username,password,"",uidnumber,gidnumber,\
                        CONCAT('/home/domains/',homedir),               \
                        CONCAT('/home/domains/',maildir),               \
                        quota,                                          \
                        name                                            \
                        FROM mailbox                                    \
                        WHERE username = '$(local_part)@$(domain)'

修改authdaemonrc文件

shell

# vi /etc/authlib/authdaemonrc

修改如下内容:

authmodulelist="authmysql"
authmodulelistorig="authmysql"

2、启动courier-authlib：

shell

# service courier-authlib start

如一切正常，命令行将返回如下信息：

Starting Courier authentication services: authdaemond

修改authdaemon socket目录权限

如果该目录权限不正确修改，maildrop及postfix等将无法正确获取用户的信息及密码认证：

shell

# chmod 755 /var/spool/authdaemon/
