试验说明：(需要软件的可以Q395061796)

服务器担任dns、mail Server的角色，ip为192.168.100.123。

客户机进行测试

软件需求：

一、修改机器名称、搭建DNS 并且安装所需软件

[root@zhangc ~]# vim /etc/sysconfig/network【修改主机名】

3 HOSTNAME=mail.yeah.net

[root@zhangc ~]# vim /etc/hosts【恢复默认值】

3 127.0.0.1 localhost.localdomain localhost

[root@zhangc ~]# vim /etc/resolv.conf【设置DNS服务器地址】

2 nameserver 192.168.100.123

[root@zhangc ~]# vim /etc/yum.repos.d/rhel-debuginfo.repo【编辑YUM仓库】

[root@zhangc ~]# yum repolist

[root@zhangc etc]# vim named.conf

[root@zhangc etc]# vim named.rfc1912.zones【增加相应的作用域】

27 zone "yeah.net" IN {

28 type master;

29 file "yeah.net.zone";

30 allow-update { none; };

31 };

[root@zhangc etc]# cd ../var/named/

[root@zhangc named]# vim yeah.net.zone【增添并编辑区域文件】

[root@zhangc named]# service named start

[root@zhangc named]# chkconfig named on

[root@zhangc named]# service sendmail stop

[root@zhangc named]# chkconfig sendmail off

安装以下服务;

[root@mail Server]# yum install httpd php php-mysql mysql mysql-server mysql-devel openssl-devel dovecot perl-DBD-MySQL tcl tcl-devel libart_lgpl libart_lgpl-devel libtool-ltdl libtool-ltdl-devel expect

[root@mail Server]# service mysqld start【启动mysqld】

[root@mail Server]# chkconfig mysqld on

[root@mail Server]# mysql

mysql> SET PASSWORD FOR root@'localhost'=PASSWORD('redhat');

mysql> SET PASSWORD FOR root@'127.0.0.1'=PASSWORD('redhat');

mysql> FLUSH PRIVILEGES;

mysql> GRANT ALL PRIVILEGES ON *.* TO root@'%' IDENTIFIED BY 'redhat';

mysql> FLUSH PRIVILEGES;

mysql> \q

[root@mail Server]# service saslauthd start【启动saslauthd】

[root@mail Server]# chkconfig saslauthd on

二、安装配置POSTFIX

[root@mail ~]# groupadd -g 2525 postfix【创建组】

[root@mail ~]# useradd -g postfix -u 2525 -s /sbin/nologin -M postfix

[root@mail ~]# groupadd -g 2526 postdrop【将postdrop的组号设置为2526】

[root@mail ~]# useradd -g postdrop -u 2526 -s /bin/false -M postdrop

[root@mail postfix-2.8.2]# tar zxvf postfix-2.8.2.tar.gz -C /usr/local/src/【拆解源文件】

[root@mail postfix-2.8.2]# cd /usr/local/src/postfix-2.8.2/

[root@mail postfix-2.8.2]# make makefiles 'CCARGS=-DHAS_MYSQL -I/usr/include/mysql -DUSE_SASL_AUTH -DUSE_CYRUS_SASL -I/usr/include/sasl -DUSE_TLS ' 'AUXLIBS=-L/usr/lib/mysql -lmysqlclient -lz -lm -L/usr/lib/sasl2 -lsasl2 -lssl -lcrypto'【预编译环境检测】

[root@mail postfix-2.8.2]# make【编译】

[root@mail postfix-2.8.2]# make install【安装】

install_root: [/] /

tempdir: [/usr/local/src/postfix-2.8.2] /tmp

以下的都使用默认目录文件夹

[root@mail postfix-2.8.2]# newaliases

[root@mail postfix-2.8.2]# postfix start

[root@mail postfix-2.8.2]# postconf -a

查看是否启动了cyrus

[root@mail ~]# mkdir /tmp/abc【创建目录】

[root@mail ~]# cd /tmp/abc/

[root@mail abc]# cp /mnt/cdrom/Server/postfix-2.3.3-2.1.el5_2.i386.rpm ./【拷贝postfix到当前目录】

[root@mail abc]# rpm2cpio postfix-2.3.3-2.1.el5_2.i386.rpm |cpio �Cid【安装】

[root@mail abc]# cd etc/rc.d/init.d/

[root@mail init.d]# cp postfix /etc/init.d/

[root@mail init.d]# vim /etc/postfix/main.cf【编辑postfix的主配置文档】

75 myhostname = mail.yeah.net

83 mydomain = yeah.net

99 myorigin = $mydomain

113 inet_interfaces = all

161 mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain

260 mynetworks = 127.0.0.0/8

三、加入安全认证功能

[root@mail sasl2]# vim /etc/postfix/main.cf【编辑postfix的主配置文档】

653 ############################CYRUS-SASL############################

654 broken_sasl_auth_clients = yes

655 smtpd_recipient_restrictions=permit_mynetworks,permit_sasl_authenticated,reject_invalid_hostname,reject_non_fq dn_hostname,reject_unknown_sender_domain,reject_non_fqdn_sender,reject_non_fqdn_recipient,reject_unknown_recip ient_domain,reject_unauth_pipelining,reject_unauth_destination

656 smtpd_sasl_auth_enable = yes

657 smtpd_sasl_local_domain = $myhostname

658 smtpd_sasl_security_options = noanonymous

659 smtpd_banner = Welcome to our $myhostname ESMTP,Warning: Version not Available!

：wq

[root@mail sasl2]# cd /usr/lib/sasl2/

[root@mail sasl2]# cp -p Sendmail.conf smtpd.conf【拷贝并编辑smtpd.conf，添加下面语句】

2 mech_list: PLAIN LOGIN

进行测试：

[root@mail sasl2]# telnet mail.yeah.net 25

ehlo mail.yeah.net

250-AUTH PLAIN LOGIN

250-AUTH=PLAIN LOGIN

四、安装Courier anthentication library

[root@mail ~]# tar jxvf courier-authlib-0.63.1.20111230.tar.bz2【拆解】

[root@mail ~]# cd courier-authlib-0.63.1.20111230

[root@mail courier-authlib-0.63.1.20111230]# ./configure --prefix=/usr/local/courier-authlib --sysconfdir=/etc --with-authmysql --with-mysql-libs=/usr/lib/mysql --with-mysql-includes=/usr/include/mysql --with-redhat --with-authmysqlrc=/etc/authmysqlrc --with-authdaemonrc=/etc/authdaemonrc --with-ltdl-lib=/usr/lib --with-ltdl-include=/usr/include【预编译环境检测】

[root@mail courier-authlib-0.63.1.20111230]# make【编译】

[root@mail courier-authlib-0.63.1.20111230]# make install【安装】

[root@mail courier-authlib-0.63.1.20111230]# chmod 755 /usr/local/courier-authlib/var/spool/authdaemon【修改权限】

[root@mail spool]# cp /etc/authdaemonrc.dist /etc/authdaemonrc

[root@mail spool]# cp /etc/authmysqlrc.dist /etc/authmysqlrc

[root@mail spool]# vim /etc/authdaemonrc

27 authmodulelist="authmysql"

34 authmodulelistorig="authmysql"

139 MYSQL_NAME_FIELD name

150 MYSQL_MAILDIR_FIELD concat('/var/mailbox/',maildir)

[root@mail ~]# cd courier-authlib-0.63.1.20111230

[root@mail courier-authlib-0.63.1.20111230]# cp courier-authlib.sysvinit /etc/init.d/courier-authlib

[root@mail courier-authlib-0.63.1.20111230]# chmod 755 /etc/init.d/courier-authlib

[root@mail courier-authlib-0.63.1.20111230]# service courier-authlib start

[root@mail courier-authlib-0.63.1.20111230]# chkconfig --add courier-authlib

[root@mail courier-authlib-0.63.1.20111230]# chkconfig --level 2345 courier-authlib on

指明库文件的路径

[root@mail courier-authlib-0.63.1.20111230]# echo "/usr/local/courier-authlib/lib/courier-authlib" >> /etc/ld.so.conf.d/courier-authlib.conf

[root@mail courier-authlib-0.63.1.20111230]# ldconfig �Cv

[root@mail courier-authlib-0.63.1.20111230]# service courier-authlib restart

新建虚拟用户邮箱所在的目录，并将其权限赋予postfix用户

[root@mail courier-authlib-0.63.1.20111230]# mkdir -pv /var/mailbox

[root@mail courier-authlib-0.63.1.20111230]# chown -R postfix /var/mailbox

[root@mail ~]# cd /usr/lib/sasl2/

[root@mail sasl2]# vim smtpd.conf

确保有以下4行

1 pwcheck_method:saslauthd

1 pwcheck_method:saslauthd

2 mech_list: PLAIN LOGIN

3 log_level: 3

4 authdaemond_path:/usr/local/courier-authlib/var/spool/authdaemon/socket

五、让postfix支持虚拟域和虚拟用户

[root@mail sasl2]# vim /etc/postfix/main.cf

661 ########################Virtual Mailbox Settings########################

662 virtual_mailbox_base = /var/mailbox

663 virtual_mailbox_maps = mysql:/etc/postfix/mysql_virtual_mailbox_maps.cf

664 virtual_mailbox_domains = mysql:/etc/postfix/mysql_virtual_domains_maps.cf

665 virtual_alias_domains =

666 virtual_alias_maps = mysql:/etc/postfix/mysql_virtual_alias_maps.cf

667 virtual_uid_maps = static:2525

668 virtual_gid_maps = static:2525

669 virtual_transport = virtual

670 maildrop_destination_recipient_limit = 1

671 maildrop_destination_concurrency_limit = 1

672 ##########################QUOTA Settings########################

673 message_size_limit = 14336000

674 virtual_mailbox_limit = 20971520

675 virtual_create_maildirsize = yes

676 virtual_mailbox_extended = yes

677 virtual_mailbox_limit_maps =

678

679 mysql:/etc/postfix/mysql_virtual_mailbox_limit_maps.cf

680 virtual_mailbox_limit_override = yes

681 virtual_maildir_limit_message = Sorry, the user's maildir has overdrawn his

682

683 diskspace quota, please Tidy your mailbox and try again later.

684 virtual_overquota_bounce = yes

使用extman源码目录下docs目录中的extmail.sql和init.sql建立数据库

[root@mail ~]# tar zxvf extman-1.1.tar.gz

[root@mail ~]# cd extman-1.1/docs/

进行测试

[root@mail docs]# cp mysql_virtual_* /etc/postfix/

3.授予用户extmail访问extmail数据库的权限

[root@mail postfix]# mysql -u root -p

Enter password:

mysql> GRANT all privileges on extmail.* TO extmail@localhost IDENTIFIED BY 'extmail';

mysql> GRANT all privileges on extmail.* TO [email protected] IDENTIFIED BY 'extmail';

mysql> FLUSH PRIVILEGES;

mysql> \q

[root@mail postfix]# service postfix restart

六、dovecot的安装

编辑/etc/dovecot.conf

[root@mail ~]# vim /etc/dovecot.conf

211 mail_location = maildir:/var/mailbox/%d/%n/Maildir

795 #passdb pam {

828 #}

869 passdb sql {

871 args = /etc/dovecot-mysql.conf

872 }

896 #userdb passwd {

903 #}

930 userdb sql {

932 args = /etc/dovecot-mysql.conf

933 }

[root@mail ~]# vim /etc/postfix/main.cf

414 home_mailbox = Mailbox

[root@mail ~]# vim /etc/dovecot-mysql.conf

1 driver = mysql

2 connect = host=localhost dbname=extmail user=extmail password=extmail

3 default_pass_scheme = CRYPT

4 password_query = SELECT username AS user,password AS password FROM mailbox WHERE username = '%u'

5 user_query = SELECT maildir, uidnumber AS uid, gidnumber AS gid FROM mailbox WHERE username = '%u'

[root@mail ~]# service dovecot restart

Stopping Dovecot Imap: [ OK ]

Starting Dovecot Imap: [ OK ]

七、安装extmail-1.2
