　　-------------------------------------------
　　

　　一、前言
　　 Extmail 是一个以perl语言编写，面向大容量/ISP级应用，免费的高性能Webmail软件，主要包括ExtMail、Extman两个部分的程序套件。ExtMail套件用于提供从浏览器中登录、使用邮件系统的Web操作界面，而Extman套件用于提供从浏览器中管理邮件系统的Web操作界面。它以GPL版权释出，设计初衷是希望设计一个适应当前高速发展的IT应用环境，满足用户多变的需求，能快速进行开发、改进和升级，适应能力强的webmail系统。
　　二、环境
　　1.系统环境
　　CentOS6.4 32位
　　2.6.32-358.el6.i686
　　2.环境配置
　　Development tool
　　Additional Development
　　Server Platform Development
　　3.更改主机名

# hostname mail.a.com
# vim /etc/sysconfig/network
  NETWORKING=yes
  HOSTNAME=mail.a.com
# hostname
  mail.a.com

　　4.所需源码包
　　courier-authlib-0.63.0.tar.bz2
　　extmail-1.2.tar.gz
　　extman-1.1.tar.gz
　　postfix-2.8.2.tar.gz
　　Unix-Syslog-0.100.tar.gz
　　三、流程分析

　　四、具体配置
　　1.安装apache和mysql

# yum install httpd  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
# service mysqld start
# mysqladmin -u root -p password '123'

　　2.卸载postfix RPM包，创建postfix和postdrop用户

# cp /etc/init.d/postfix /etc/init.d/postfix.bak
# yum remove postfix
# id postfix
uid=89(postfix) gid=89(postfix) groups=89(postfix),12(mail)
# groupdel postfix
groupdel: cannot remove the primary group of user 'postfix'
# userdel -r postfix
userdel: /var/spool/postfix not owned by postfix, not removing
# groupdel postfix
groupdel: group 'postfix' does not exist
# userdel -r postfix
userdel: user 'postfix' does not exist
# groupadd -g 2525 -r postfix
# useradd -g postfix -u 2525 -s /sbin/nologin -M postfix
# groupdel postdrop
# userdel -r postdrop
userdel: user 'postdrop' does not exist
# groupadd -g 2526 -r postdrop
# useradd -g postdrop -u 2526 -s /sbin/nologin -M postdrop
# id postfix
uid=2525(postfix) gid=2525(postfix) groups=2525(postfix)
# id postdrop
uid=2526(postdrop) gid=2526(postdrop) groups=2526(postdrop)

　　3.安装postfix

# tar -zxvf postfix-2.8.2.tar.gz -C /usr/local/src/
# cd /usr/local/src/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'
# make
# make install

　　[]号中的是缺省值，”]”后的是输入值，省略的表示采用默认值。

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

queue_directory: [/var/spool/postfix]
readme_directory: [no]
sendmail_path: [/usr/sbin/sendmail]
setgid_group: [postdrop]

# newaliases  生成别名二进制文件，这个步骤如果忽略，会造成postfix效率极低
# cd /etc/init.d/
# mv postfix.bak postfix
# chown -R postfix /var/lib/postfix/
# chown -R postfix /var/spool/postfix/private/
# chown -R postfix /var/spool/postfix/public/
# service  postfix restart
[root@localhost init.d]# netstat -tupln |grep 25

# chkconfig --add postfix
# chkconfig  postfix  on

　　3-1.配置postfix

# vim /etc/postfix/main.cf
75 myhostname = mail.a.com
83 mydomain = a.com
99 myorigin = $mydomain
161 mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain
260 mynetworks = 127.0.0.0/8
# service  postfix restart
# cd /usr/local/lib
# mkdir sasl2
# cd sasl2/
# vim smtpd.conf
1 pwcheck_method: saslauthd
2 mech_list: PLAIN LOGIN
# service postfix restart
# service saslauthd restart
# chkconfig saslauthd on
# vim /etc/postfix/main.cf
652 broken_sasl_auth_clients = yes

654 smtpd_sasl_auth_enable = yes
655 smtpd_sasl_local_domain = $myhostname
656 smtpd_sasl_security_options = noanonymous
657 smtpd_banner = Welcome to our $myhostname ESMTP,Warning: Version not Available!

　　4.安装courier-authlib

# tar -jxvf courier-authlib-0.63.0.tar.bz2 -C /usr/local/src/
# cd /usr/local/src/courier-authlib-0.63.0/
# ./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
# make && make install
# cd /usr/local/courier-authlib/
# vim /etc/ld.so.conf.d/courier-authlib.conf

　　5.创建mailbox

# mkdir /var/mailbox
# chown -R postfix /var/mailbox/
# vim /usr/local/lib/sasl2/smtpd.conf  （覆盖原来两行）
  1 pwcheck_method: authdaemond
  2 log_level: 3
  3 mech_list:PLAIN LOGIN
  4 authdaemond_path:/usr/local/courier-authlib/var/spool/authdaemon/socket
# service saslauthd restart
# service courier-authlib restart
# vim /etc/postfix/main.cf

　　6.导入数据库

# tar -zxvf extman-1.1.tar.gz
# cd extman-1.1/docs/
# mysql -u root -p <extmail.sql
Enter password:
# mysql -u root -p <init.sql
Enter password:

　　7.安装dovecot

# cd extman-1.1/docs/
# cp mysql_virtual_* /etc/postfix/
# service postfix restart
# yum install dovecot
# cd /etc/dovecot/conf.d/
# vim 10-mail.conf
 24 mail_location = maildir:/var/mailbox/%d/%n/Maildir
# vim auth-sql.conf.ext
 9   args = /etc/dovecot/dovecot-sql.conf
 21   args = /etc/dovecot/dovecot-sql.conf
# vim /etc/dovecot/dovecot-sql.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'
# service dovecot start
# chkconfig dovecot on

　　8.安装并配置extmail

# tar -zxvf extmail-1.2.tar.gz
# mkdir /var/www/extsuite
# mv extman-1.1 extmail-1.2 /var/www/extsuite/
# cd /var/www/extsuite/
# mv extmail-1.2/ extmail
# mv extman-1.1/ extman
# cd extmail/
# cp webmail.cf.default webmail.cf
# vim webmail.cf
 77 SYS_USER_LANG = zh_CN
127 SYS_MAILDIR_BASE = /var/mailbox
139 SYS_MYSQL_USER = extmail
140 SYS_MYSQL_PASS = extmail
197 SYS_AUTHLIB_SOCKET = /usr/local/courier-authlib/var/spool/authdaemon/socket
# chown -R postfix.postfix /var/www/extsuite/extmail/cgi/

　　9.配置extman

# cd /var/www/extsuite/extman/
# cp webman.cf.default webman.cf
# vim webman.cf
 12 SYS_MAILDIR_BASE = /var/mailbox
 21 SYS_CAPTCHA_ON = 0 (关闭验证码)
 39 SYS_LANG = zh_CN
# vim /etc/postfix/main.cf
415 home_mailbox = Maildir/
# service postfix restart
# chown -R postfix.postfix /var/www/extsuite/extman/cgi/
# vim /etc/httpd/conf/httpd.conf
 242 User postfix
 243 Group postfix
1010 <VirtualHost *:80>
1011 ServerName mail.test.com
1012 DocumentRoot /var/www/extsuite/extmail/html/1013 ScriptAlias /extmail/cgi /var/www/extsuite/extmail/cgi

1016 Alias /extman /var/www/extsuite/extman/html

# service httpd restart

　　五、测试
　　1.浏览器访问http://服务器IP/extmail

　　2.登陆邮箱管理，创建域。

　　3.默认管理帐号为：root@extmail.org 密码为：extmail*123*

　　4.创建虚拟域 a.com

　　5.创建虚拟域 b.com

　　6.创建用户user10，隶属于虚拟域a.com

　　7.创建用户user11，隶属于虚拟域b.com

　　8.user10登陆邮箱

　　9.user10向user11发送一封测试邮件

　　10.user10在写邮件

　　11.user11登陆邮箱

　　12.user11查看信件，来自于user10

　　六、后台mysql数据库用户信息
