本文将详细介绍如何使用postfix,extman,extmail等一系列开源软件构建适合企业应用的邮件系统，测试服务器平台为RHEL5.4 32位操作系统，在开始之前，请部署好LAMP环境，这方面的介绍可以参考我的另一篇文章：http://ylw6006.blog.51cto.com/470441/657907，如果要做到收发邮件均没有问题，需要DNS的邮件交换记录(MX)支持,这方面的设置不在本文中介绍…
一：安装courier-authlib
1：使用该验证库，可以使用mysql验证邮件账户
[root@orcl ~]# cd /usr/local/src/tarbag
[root@orcl tarbag]# wget http://sourceforge.net/projects/courier/files/authlib/0.63.0/courier-authlib-0.63.0.tar.bz2/download
[root@orcl tarbag]# tar -jxvf courier-authlib-0.63.0.tar.bz2 -C ../software/
[root@orcl tarbag]# cd ../software/courier-authlib-0.63.0/
[root@orcl courier-authlib-0.63.0]# groupadd postfix -g 1000
[root@orcl courier-authlib-0.63.0]# groupadd vmail -g 1001
[root@orcl courier-authlib-0.63.0]# groupadd postdrop -g 1002
[root@orcl courier-authlib-0.63.0]# useradd -u 1001 -g 1000 vmail
[root@orcl courier-authlib-0.63.0]# useradd -u 1000 -g 1000 postfix
[root@orcl courier-authlib-0.63.0]# id vmail
uid=1001(vmail) gid=1000(postfix) groups=1000(postfix)
[root@orcl courier-authlib-0.63.0]# id postfix
uid=1000(postfix) gid=1000(postfix) groups=1000(postfix)
[root@orcl courier-authlib-0.63.0]# ./configure --prefix=/usr/local/courier-authlib --with-mailuser=vmail --with-mailgroup=vmail --sysconfdir=/etc --without-authpam --without-authldap --without-authpwd --without-authshadow --without-authvchkpw --without-authpgsql --with-authmysql --with-mysql-libs=/usr/local/mysql/lib/mysql --with-mysql-includes=/usr/local/mysql/include/mysql --with-redhat --with-authmysqlrc=/etc/authmysqlrc --with-authdaemonrc=/etc/authdaemonrc CFLAGS="-march=i686 -O2 -fexpensive-optimizations" CXXFLAGS="-march=i686 -O2 -fexpensive-optimizations"
[root@orcl courier-authlib-0.63.0]# make && make install
[root@orcl courier-authlib-0.63.0]# ls /usr/local/courier-authlib/
bin include lib libexec sbin share var
[root@orcl courier-authlib-0.63.0]# echo '/usr/local/courier-authlib/lib/courier-authlib/' >> /etc/ld.so.conf
[root@orcl courier-authlib-0.63.0]# ldconfig
备注：如果是64位系统，需要将i686修改位x86-64，各编译选项的含义可以使用./configrue --help来获取
2：修改authlib库相关配置文件
[root@orcl ~]# cp /etc/authdaemonrc.dist /etc/authdaemonrc
[root@orcl ~]# grep -v '^#' /etc/authdaemonrc |grep -v '^$'
authmodulelist="authmysql"
authmodulelistorig="authmysql"
daemons=5
authdaemonvar=/usr/local/courier-authlib/var/spool/authdaemon
DEBUG_LOGIN=0
DEFAULTOPTIONS=""
LOGGEROPTS=""
[root@orcl ~]# cp /etc/authmysqlrc.dist /etc/authmysqlrc
[root@orcl ~]# grep -v '^#' /etc/authmysqlrc |grep -v '^$'
MYSQL_SERVER 127.0.0.1
MYSQL_USERNAME extmail
MYSQL_PASSWORD 123456
MYSQL_SOCKET /tmp/mysql.sock
MYSQL_PORT 3306
MYSQL_OPT 0
MYSQL_DATABASE extmail
MYSQL_USER_TABLE mailbox
MYSQL_CRYPT_PWFIELD password
MYSQL_UID_FIELD 1001
MYSQL_GID_FIELD 1001
MYSQL_LOGIN_FIELD username
MYSQL_HOME_FIELD concat('/email/mailbox/',homedir)
MYSQL_NAME_FIELD name
MYSQL_MAILDIR_FIELD concat('/email/mailbox/',maildir)
3：启动authlib服务
[root@orcl ~]# /usr/local/courier-authlib/sbin/authdaemond start
[root@orcl ~]# ps -ef |grep courier
root 31874 1 0 11:35 ? 00:00:00 /usr/local/courier-authlib/sbin/courierlogger -pid=/usr/local/courier-authlib/var/spool/authdaemon/pid -start /usr/local/courier-authlib/libexec/courier-authlib/authdaemond
root 31875 31874 0 11:35 ? 00:00:00 /usr/local/courier-authlib/libexec/courier-authlib/authdaemond
root 31876 31875 0 11:35 ? 00:00:00 /usr/local/courier-authlib/libexec/courier-authlib/authdaemond
root 31877 31875 0 11:35 ? 00:00:00 /usr/local/courier-authlib/libexec/courier-authlib/authdaemond
root 31878 31875 0 11:35 ? 00:00:00 /usr/local/courier-authlib/libexec/courier-authlib/authdaemond
root 31879 31875 0 11:35 ? 00:00:00 /usr/local/courier-authlib/libexec/courier-authlib/authdaemond
root 31880 31875 0 11:35 ? 00:00:00 /usr/local/courier-authlib/libexec/courier-authlib/authdaemond
[root@orcl ~]# echo '/usr/local/courier-authlib/sbin/authdaemond start' > /etc/rc.local
二:安装 cyrus-sasl,SASL (Simple Authentication Security Layer)简单认证安全层,功能主要是用于SMTP认证;而 Cyrus SASL是SASL的一个实现
1:卸载系统自带的sasl rpm包，使用--nodeps选项强制卸载
[root@orcl ~]# rpm -qa |grep sasl
cyrus-sasl-2.1.22-5.el5
cyrus-sasl-devel-2.1.22-5.el5
cyrus-sasl-lib-2.1.22-5.el5
cyrus-sasl-plain-2.1.22-5.el5
[root@orcl ~]# rpm -e $(rpm -qa |grep cyrus-sasl) --nodeps
[root@orcl ~]# rpm -qa |grep sasl |wc -l
0
[root@orcl ~]# cd /usr/local/src/tarbag/
[root@orcl tarbag]# wget ftp://ftp.andrew.cmu.edu/pub/cyrus-mail/cyrus-sasl-2.1.22.tar.gz
[root@orcl tarbag]# tar -zxvf cyrus-sasl-2.1.22.tar.gz -C ../software/
[root@orcl tarbag]# cd ../software/cyrus-sasl-2.1.22/
[root@orcl cyrus-sasl-2.1.22]# ./configure --prefix=/usr/local/sasl2 --with-mysql=/usr/local/mysql --disable-sample --disable-saslauthd --disable-pwcheck --disable-cram --disable-digest --disable-krb4 --disable-gssapi --disable-anon --enable-plain --enable-login --enable-sql --disable-ntlm --disable-otp --disable-srp --disable-srp-setpass --with-authdaemond=/usr/local/courier-authlib/var/spool/authdaemon/socket --with-mysql-includes=/usr/local/mysql/include/ --with-mysql-libs=/usr/local/mysql/lib/mysql
[root@orcl cyrus-sasl-2.1.22]# make && make install
[root@orcl cyrus-sasl-2.1.22]# ls /usr/local/sasl2/
include lib man sbin
[root@orcl cyrus-sasl-2.1.22]# rm -rf /usr/lib/sasl2/
[root@orcl cyrus-sasl-2.1.22]# ln -s /usr/local/sasl2/lib/sasl2/ /usr/lib
[root@orcl ~]# tail -2 /etc/ld.so.conf
/usr/local/sasl2/lib/sasl2
/usr/local/sasl2/lib
[root@orcl ~]# ldconfig
2：编辑smtpd认证配置文件，该文件默认不存在
[root@orcl ~]# cat /usr/local/sasl2/lib/sasl2/smtpd.conf
pwcheck_method: authdaemond
log_level: 3
mech_list: PLAIN LOGIN
authdaemond_path:/usr/local/courier-authlib/var/spool/authdaemon/socket
3：创建相关目录并启动测试
[root@orcl ~]# mkdir -p /var/state/saslauthd
[root@orcl ~]# /usr/local/sasl2/sbin/saslauthd -a shadow pam -d

[root@orcl ~]# ln -s /usr/local/BerkeleyDB/include/db_cxx.h /usr/include/
[root@orcl ~]# echo '/usr/local/BerkeleyDB/lib' >> /etc/ld.so.conf
[root@orcl ~]# ldconfig
四:安装postfix
1：关闭sendmail
[root@orcl ~]# service sendmail stop
Shutting down sm-client: [ OK ]
Shutting down sendmail: [ OK ]
[root@orcl ~]# chkconfig sendmail off
2：下载postfix源码包并编译安装
[root@orcl ~]# echo '/usr/local/mysql/lib/mysql/' >> /etc/ld.so.conf
[root@orcl ~]# ldconfig
[root@orcl ~]# cd /usr/local/src/tarbag/
[root@orcl tarbag]# wget ftp://ftp.cuhk.edu.hk/pub/packages/mail-server/postfix/official/postfix-2.8.0.tar.gz
[root@orcl tarbag]# wget http://vda.sourceforge.net/VDA/postfix-vda-2.8.0.patch //支持磁盘配额的补丁
[root@orcl tarbag]# tar -zxvf postfix-2.8.0.tar.gz -C ../software/

九：测试和排错, extman默认管理帐号为：root@extmail.org 密码为：extmail*123*
1：安装GD，若未安装，则会出现验证码无法正常显示
[root@orcl ~]# cd /usr/local/src/tarbag/
[root@orcl tarbag]# tar -zxvf GD-2.35.tar.gz -C ../software/
[root@orcl tarbag]# cd ../software/GD-2.35/
[root@orcl GD-2.35]# perl Makefile.PL
[root@orcl GD-2.35]# make && make install
2:出现下图中的情况，需要重新安装前面卸载掉的db4和db4-devel
[root@orcl ~]# yum -y install db4 db4-devel
3:出现下图中的情况，需要安装UNix-syslog
[root@orcl ~]# cd /usr/local/src/tarbag/
[root@orcl tarbag]# gzip -d Unix-Syslog-1.1.tar.gz
[root@orcl tarbag]# tar -xvf Unix-Syslog-1.1.tar -C ../software/
[root@orcl tarbag]# cd ../software/Unix-Syslog-1.1/
[root@orcl Unix-Syslog-1.1]# ls
Artistic Changes Makefile.PL MANIFEST META.yml README Syslog.pm Syslog.xs test.pl
[root@orcl Unix-Syslog-1.1]# perl Makefile.PL

Looks good
Writing Makefile for Unix::Syslog
[root@orcl Unix-Syslog-1.1]# make && make install
4:新建邮件域，登陆出错
安装perl-DBD-MySQL后重新登陆
[root@orcl ~]# yum -y install perl-DBD-MySQL
5: 发信测试
[root@orcl ~]# tail -f /var/log/maillog

6:extman日志分析
[root@orcl ~]# cd /usr/local/src/tarbag/
[root@orcl tarbag]# wget http://oss.oetiker.ch/rrdtool/pub/rrdtool-1.4.5.tar.gz
[root@orcl tarbag]# tar -zxvf rrdtool-1.4.5.tar.gz -C ../software/

十：增加FCGI支持,主要是为了获得优异的web效能
1:安装mod_fastcgi模块
[root@orcl ~]# cd /usr/local/src/tarbag/
[root@orcl tarbag]# wget http://www.fastcgi.com/dist/mod_fastcgi-2.4.6.tar.gz
[root@orcl tarbag]# tar -zxvf mod_fastcgi-2.4.6.tar.gz -C ../software/
[root@orcl tarbag]# cd ../software/mod_fastcgi-2.4.6/
[root@orcl mod_fastcgi-2.4.6]# cp Makefile.AP2 Makefile
[root@orcl mod_fastcgi-2.4.6]# make top_dir=/usr/local/apache2.2.16/ install
[root@orcl mod_fastcgi-2.4.6]# ls /usr/local/apache2.2.16/modules/mod_fastcgi.so
/usr/local/apache2.2.16/modules/mod_fastcgi.so
2：安装perl-FCGI模块，使extmail支持fastcgi
[root@orcl ~]# rpm -ivh http://ftp.belnet.be/packages/dries.ulyssis.org/redhat/el5/en/i386/RPMS.dries/perl-FCGI-0.67-1.2.el5.rf.i386.rpm //32位系统
[root@orcl ~]# rpm -ivh http://ftp.belnet.be/packages/dries.ulyssis.org/redhat/el5/en/x86_64/RPMS.dries/perl-FCGI-0.67-1.2.el5.rf.x86_64.rpm //64位系统
3：配置apache,extmail支持fastcgi
[root@orcl ~]# egrep 'fast|9000' /usr/local/apache2.2.16/conf/httpd.conf
LoadModule fastcgi_module modules/mod_fastcgi.so
<Ifmodule mod_fastcgi.c>

</Directory>
</VirtualHost>
[root@orcl ~]# egrep 'vmail|www|9000' /www/extmail/dispatch-init
PORT=9000
SU_UID=vmail
SU_GID=vmail
BASE=/www/extmail
4:启动fastcgi server
[root@orcl ~]# /www/extmail/dispatch-init start
Starting extmail FCGI server...
[root@orcl ~]# ps -ef |grep dispatch
vmail 23661 1 0 09:43 ? 00:00:00 dispatch.fcgi (master)

[root@orcl ~]# echo '/www/extmail/dispatch-init start' >> /etc/rc.local
5：重启apache
[root@orcl ~]# /usr/local/apache2.2.16/bin/apachectl -t
Syntax OK
[root@orcl ~]# /usr/local/apache2.2.16/bin/apachectl -k restart
备注：本文的安装过程非常繁琐，需要用到的软件也很多，因而在本文中没有提供下载地址的软件将会统一打包放在附件中，后期会重点研究下垃圾邮件过滤和邮件病毒的查杀；另外，本文参考了胡双峰同学写的博文，在此深表感谢，双峰同学博客地址：http://blog.csdn.net/deccmtd/
