1:安裝centos 3&&mysql略過.....
2:postfix安裝配置
a:down 所需要的RPM包kernel 2.4.21.-47.el
http://mirror.centos.org/centos/3.8/contrib/i386/RPMS/postfix-2.0.20-1.centos3.1.i386.rpm
rpm -ivh postfix-2.0.*.rpm
postconf -n > /etc/postfix/main2.cf mv /etc/postfix/main.cf /etc/postfix/main.cf.old mv /etc/postfix/main2.cf /etc/postfix/main.cf
再編輯main.cf：
vi /etc/postfix/main.cf
增加如下內容：
# hostname mynetworks = 127.0.0.1 myhostname = mail.test1.com mydestination = $mynetworks $myhostname # banner mail_name = Postfix - by extmail.org smtpd_banner = $myhostname ESMTP $mail_name # response immediately smtpd_error_sleep_time = 0s unknown_local_recipient_reject_code = 450 # extmail config here virtual_alias_maps = mysql:/etc/postfix/mysql_virtual_alias_maps.cf virtual_mailbox_domains = mysql:/etc/postfix/mysql_virtual_domains_maps.cf virtual_mailbox_maps = mysql:/etc/postfix/mysql_virtual_mailbox_maps.cf virtual_transport = maildrop:
編輯mysql_virtual_alias_maps.cf
vi /etc/postfix/mysql_virtual_alias_maps.cf
內容如下：
user = mail password = mail hosts = localhost dbname = mail table = alias select_field = goto where_field = address
編輯mysql_virtual_domains_maps.cf
vi /etc/postfix/mysql_virtual_domains_maps.cf
內容如下：
user = mail password = mail hosts = localhost dbname = mail table = domain select_field = description where_field = domain #additional_conditions = and backupmx ='0' and active ='1'
編輯mysql_virtual_mailbox_maps.cf
vi /etc/postfix/mysql_virtual_mailbox_maps.cf
內容如下：
user = mail password = mail hosts = localhost dbname = mail table = mailbox select_field = maildir where_field = username #additional_conditions = and active = '1'
down 官方提供的包
http://www.extmail.org/source/ExtMail-Solution-Linux-0.1.tar.gz
解壓後有很多可用的RPM...官方的包是提供給RHEL4.X的...所以本文所用到的centos3.8應適當更改其中
某些包的版本
rpm -ivh RPMS/libtool-libs-1.5.6-4.EL4.1.c4.3.i386.rpm rpm -ivh RPMS/courier-authlib-0.57-1hzq.i386.rpm rpm -ivh RPMS/courier-authlib-devel-0.57-1hzq.i386.rpm rpm -ivh RPMS/courier-authlib-mysql-0.57-1hzq.i386.rpm
編輯/etc/authlib/authmysqlrc文件
MYSQL_SERVER localhost
MYSQL_USERNAME mail
MYSQL_PASSWORD mail
MYSQL_SOCKET /var/lib/mysql/mysql.sock
MYSQL_PORT 3306
MYSQL_OPT 0
MYSQL_DATABASE mail
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)'
存盤退出後啓動courier-authlib：
/etc/init.d/courier-authlib start
如一切正常，命令行將返回如下信息：
Starting Courier authentication services: authdaemond
修改authdaemon socket目錄權限
如果該目錄權限不正確修改，maildrop及postfix等將無法正確獲取用戶的信息及密碼認證：
chmod 755 /var/spool/authdaemon/
安裝maildrop
