linux-postfix邮件系统架设全攻略(5)

---------------------------------------------------------------------
 六、配置dovecot
# vi /etc/dovecot.conf
mail_location = maildir:/var/mailbox/%d/%n/Maildir
……
auth default {
    mechanisms = plain
    passdb sql {
        args = /etc/dovecot-mysql.conf
    }
    userdb sql {
        args = /etc/dovecot-mysql.conf
    }
    ……
# vi /etc/dovecot-mysql.conf                                   
driver = mysql
connect = host=localhost dbname=extmail user=extmail password=extmail
default_pass_scheme = CRYPT
password_query = SELECT username AS user,password AS password FROM mailbox WHERE username = '%u'                           
user_query = SELECT maildir, uidnumber AS uid, gidnumber AS gid FROM mailbox WHERE username = '%u'
 
接下来启动dovecot服务：
# service dovecot start
# chkconfig dovecot on
   
 
七、安装Extmail-1.2
1、安装
# tar zxvf extmail-1.2.tar.gz
# mkdir -pv /var/www/extsuite
# mv extmail-1.2 /var/www/extsuite/extmail
# cp /var/www/extsuite/extmail/webmail.cf.default    /var/www/extsuite/extmail/webmail.cf
   
2、修改主配置文件
#vi /var/www/extsuite/extmail/webmail.cf
   
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
