/article/4130594.html 转载致此处，人稍微做了修改！
首先说明：这里借鉴了crastyl的博文（http://blog.chinaunix.net/u1/57953/showart.php?id=1211463），然后在此基础上修正了一些错误，安装而成。目前已经上线并使用，现把安装过程总结如下：
一.首先介绍安装环境：
OS：centos5.4最小化安装，选择了组件 base，devlopment libraries development tools editors text-base internet 这几个组件，其他的一概不选。安装系统完毕，直接进行yum update -y &升级。
在终端输入setup命令 选择firewall configuration 将security level 与SELinux 改为disabled，目的是为了避免在安装调试时产生不必要的麻烦，在系统安装完成后，可以自己去调试安全部分，在这里将不作详细介绍。
二.组件选择说明：
我们能用RPM 安装的，我们将采用rpm 安装，如果rpm没有的，我们将创建自己的rpm。部分软件简介：
1、AMP －－－apache（web服务） 、mysql（数据库）、php（非必需） 的简称
2、postfix －－mta 邮件系统核心
3、courier-authlib－－一个为courier-imap，maildrop，sasl2 提供用户信息的后台进程序
4、courier-imap －－提供pop3,pop3s,imap,imaps 服务的程序
5、dspam clamd －－提供内容过滤
6、extmail －－一个著名的webmail程序
7、extman －－与extmail集成的后台管理程序
三：组件安装
1、安装AMP
[root@localhost ~]# yum -y install httpd httpd-devel mysql mysql-devel mysql-server php php-xml php-cli php-pdo php-mbstring php-mcrypt php-gd php-common php-devel php-mysql
修改启动配置并启动
[root@localhost ~]# chkconfig --level 345 mysqld on
[root@localhost ~]# chkconfig --level 345 httpd on
[root@localhost ~]# service mysqld start
[root@localhost ~]# service httpd start
2.下载extman（http://www.extmail.org/cgi-bin/download.cgi）
[root@localhost ~]# tar zxf extman-1.1.tar.gz
[root@localhost ~]# cd extman-1.1/docs/
[root@localhost docs]# mysql -uroot <extmail.sql
[root@localhost docs]# mysql -uroot <init.sql
3、RPM 简介
下面我们将采用rpm 的方式安装软件
/usr/src/redhat/SPEC spec 文件夹，通常是rpm文件夹
/usr/src/redhat/RPMS 是生成rpm 的文件，下面还有i368,i486 等子文件夹，一般我们用i386 架构
/usr/src/redhat/SOURCE 源文件文件夹
为了安装时切换目录的方便，我们将目录存放到一个shell变量里。
[root@localhost ~]# export RPMS=/usr/src/redhat/RPMS
[root@localhost ~]# export SOURCE=/usr/src/redhat/SOURCES
[root@localhost ~]# export SPEC=/usr/src/redhat/SPECS
在下面安装过程中，大家要记住cd $RPMS 与cd /usr/src/redhat/RPMS 的目的是一样的，只是shell变量的替换。
4、安装authlib （courier-authlib-0.63.0）
A、安装依懒的包
[root@localhost ~]# yum -y install postgresql-devel expect libtool-ltdl-devel
[root@localhost ~]# wget http://prdownloads.sourceforge.net/courier/courier-authlib-0.63.0.tar.bz2
[root@localhost ~]# tar xjf courier-authlib-0.63.0.tar.bz2
[root@localhost ~]# cd courier-authlib-0.63.0
[root@localhost courier-authlib-0.63.0]# cp courier-authlib.spec $SPEC
[root@localhost courier-authlib-0.63.0]# cd ..
[root@localhost ~]# cp courier-authlib-0.63.0.tar.bz2 $SOURCE
[root@localhost ~]# cd $SPEC
[root@localhost SPECS]# rpmbuild -bb courier-authlib.spec （创建rpm文件）
B、安装生成的rpm
[root@localhost SPECS]# cd $RPMS/i386
[root@localhost i386]# rpm -ivh courier-authlib-0.63.0-1.i386.rpm
[root@localhost i386]# rpm -ivh courier-authlib-devel-0.63.0-1.i386.rpm
[root@localhost i386]# rpm -ivh courier-authlib-mysql-0.63.0-1.i386.rpm
C、配置authlibdaemon
[root@localhost i386]# cd /etc/authlib/
[root@localhost authlib]# mv authdaemonrc authdaemonrc.bak
[root@localhost authlib]# vim authdaemonrc
输入下面的内容：
authmodulelist="authmysql"
authmodulelistorig="authmysql"
daemons=10
authdaemonvar=/var/spool/authdaemon
DEBUG_LOGIN=2
DEFAULTOPTIONS="wbnodsn=1"
LOGGEROPTS=""
D、配置authmysqlrc
[root@localhost authlib]# mv authmysqlrc authmysqlrc.bak
[root@localhost authlib]# vim authmysqlrc
输入下面的内容：
MYSQL_SERVER localhost
MYSQL_USERNAME extmail
MYSQL_PASSWORD extmail
MYSQL_PORT 0
MYSQL_SOCKET /var/lib/mysql/mysql.sock
MYSQL_OPT 0
MYSQL_DATABASE extmail
MYSQL_SELECT_CLAUSE SELECT username,password,"",uidnumber,gidnumber,\
CONCAT('/home/domains/',homedir), \
CONCAT('/home/domains/',maildir), \
quota, \
name \
FROM mailbox \
WHERE username = '$(local_part)@$(domain)'
E、启动authlib
[root@localhost ~]# service courier-authlib start
Starting Courier authentication services: authdaemond
[root@localhost ~]# chmod 777 /var/spool/authdaemon/
5.安装courier-imap
由于courier-imap 不能用root身份生成rpm那么我们新建一个普通用户，并创建一个rpm环境
[root@localhost ~]# useradd yiyou 在这里添加自己的用户
软件包依懒需要安装openldap-server，rpm创建完成后可以删除
[root@localhost ~]# yum -y install openldap-servers
[root@localhost ~]# su - yiyou
[yiyou@localhost ~]$ mkdir -p rpm/{BUILD,RPMS,SOURCES,SPECS,SRPMS}
[yiyou@localhost ~]$ vim ~/.rpmmacros
输入内容：
%_topdir /home/yiyou/rpm
[yiyou@localhost ~]$ wget http://prdownloads.sourceforge.net/courier/courier-imap-4.7.0.tar.bz2
[yiyou@localhost ~]$ cp courier-imap-4.7.0.tar.bz2 rpm/SOURCES/
[yiyou@localhost ~]$ tar xjf courier-imap-4.7.0.tar.bz2
[yiyou@localhost ~]$ cd courier-imap-4.7.0
[yiyou@localhost courier-imap-4.7.0]$ cp courier-imap.spec ../rpm/SPECS/
[yiyou@localhost courier-imap-4.7.0]$ cd ../rpm/SPECS/
编辑courier-imap.spec 将下面的内容：
%if %suse_version
BuildRequires: rpm >= 3.0.5 /usr/bin/sed openldap2 openldap2-devel %([ %{suse_version} -gt 819 ] && echo /usr/include/fam.h)
%else
BuildRequires: rpm >= 4.0.2 sed /usr/include/fam.h openldap-devel openldap-servers
%endif
改为：将此处fam.h 去掉 此处好像没有openldap相关选项 2010-1-12
%if %suse_version 在这里好像提示没有安装openldap-server yum install openldap* 还真没装
BuildRequires: rpm >= 3.0.5 /usr/bin/sed openldap2 openldap2-devel
%else
BuildRequires: rpm >= 4.0.2 sed openldap-devel openldap-servers
%endif
创建rpm
[yiyou@localhost SPECS]$ rpmbuild -bb courier-imap.spec
完成rpm后，输入exit退出当前用户。
[root@localhost ~]# rpm -ivh /home/yiyou/rpm/RPMS/i386/courier-imap-4.7.0-1.i386.rpm
[root@localhost ~]# service courier-imap start
6.安装cyrus-sasl
[root@localhost ~]# yum install -y cyrus-sasl-devel cyrus-sasl-plain cyrus-sasl cyrus-sasl-lib
A.配置sasl2
创建/usr/lib/sasl2/smtpd.conf 文件，输入下面的内容：
pwcheck_method:authdaemond
log_level:3
mech_list:PLAIN LOGIN
authdaemond_path:/var/spool/authdaemon/socket
7、安装postfix 升级至2.6.5
A、下载软件包
[root@localhost i386]# cd
[root@localhost ~]# wget http://ftp.wl0.org/official/2.6/SRPMS/postfix-2.6.5-1.src.rpm
[root@localhost ~]# rpm -ivh postfix-2.6.5-1.src.rpm
[root@localhost ~]# cd $SPEC
编辑postfix.spec 修改下面的选项
%define distribution rhel-5.0
%define with_mysql_redhat 1
%define with_sasl 2
%define with_vda 1
%define with_pcre 1
B、创建rpm
[root@localhost SPECS]# rpmbuild -bb postfix.spec
[root@localhost RPMS]# cd $RPMS/i386
[root@localhost i386]# rpm -ivh postfix-2.6.5-1.rhel5.i386.rpm
C、切换mta
[root@localhost i386]# alternatives --config mta （选择2，postfix）
[root@localhost i386]# rpm -e sendmail
[root@localhost i386]# cd /usr/sbin/
[root@localhost sbin]# mv sendmail sendmail.bak
[root@localhost sbin]# newaliases
[root@localhost sbin]# ln -s sendmail.postfix sendmail
D、配置postfix
[root@localhost ~]# cd /etc/postfix/
[root@localhost postfix]# mv main.cf main.cf.bak
[root@localhost postfix]# vim main.cf
输入下面的内容：
queue_directory = /var/spool/postfix
command_directory = /usr/sbin
daemon_directory = /usr/libexec/postfix
data_directory = /var/lib/postfix
mail_owner = postfix
unknown_local_recipient_reject_code = 550
debug_peer_level = 2
debugger_command =
PATH=/bin:/usr/bin:/usr/local/bin:/usr/X11R6/bin
ddd $daemon_directory/$process_name $process_id & sleep 5
sendmail_path = /usr/sbin/sendmail.postfix
newaliases_path = /usr/bin/newaliases.postfix
mailq_path = /usr/bin/mailq.postfix
setgid_group = postdrop
html_directory = /usr/share/doc/postfix-2.6.5-documentation/html
manpage_directory = /usr/share/man
sample_directory = /etc/postfix
readme_directory = /usr/share/doc/postfix-2.6.5-documentation/readme
alias_database = hash:/etc/postfix/aliases
alias_maps = hash:/etc/postfix/aliases
myhostname = mail.360book.com.cn(修改为自己的域名)
mydomain = 360book.com.cn(修改为自己的域名)
mydestination = $myhostname
smtpd_banner = 360book.com.cn ESMTP Mail System(修改为自己的域名)
message_size_limit = 14680064
virtual_alias_maps = mysql:/etc/postfix/mysql_virtual_alias_maps.cf
virtual_mailbox_base = /home/domains
virtual_mailbox_domains = mysql:/etc/postfix/mysql_virtual_domains_maps.cf
virtual_mailbox_maps = mysql:/etc/postfix/mysql_virtual_mailbox_maps.cf
virtual_mailbox_limit_maps = mysql:/etc/postfix/mysql_virtual_limit_maps.cf
virtual_transport = maildrop
maildrop_destination_recipient_limit = 1
#sasl
smtpd_sasl_auth_enable = yes
smtpd_sasl2_auth_enable = yes
smtpd_sasl_security_options = noanonymous
broken_sasl_auth_clients = yes
smtpd_recipient_restrictions =
permit_mynetworks=,
permit_sasl_authenticated=,
reject_unauth_destination=,
reject_unauth_pipelining=,
reject_invalid_hostname=
dspam_destination_recipient_limit = 1
复制extman/docs 目录的cf 文件到/etc/postfix
[root@localhost postfix]# cp /root/extman-1.1/docs/mysql_virtual_* .
因为配置文件的用户、密码与数据库时一样，所以不用修改。
[root@localhost postfix]# service postfix start
9、安装maildrop
A、下载生成RPM
[root@localhost postfix]# cd
[root@localhost ~]# wget http://prdownloads.sourceforge.net/courier/maildrop-2.3.0.tar.bz2
[root@localhost ~]# cp maildrop-2.3.0.tar.bz2 $SOURCE
[root@localhost ~]# tar xjf maildrop-2.3.0.tar.bz2
[root@localhost ~]# cd maildrop-2.3.0
[root@localhost maildrop-2.3.0]# cp maildrop.spec $SPEC
[root@localhost maildrop-2.3.0]# cd $SPEC
编辑maildrop.spec 把下面：
BuildRequires: /usr/include/fam.h gdbm-devel pcre-devel
改为：
BuildRequires: gdbm-devel pcre-devel
把下面：
%configure --with-devel --enable-userdb --enable-maildirquota \
--enable-syslog=1 --enable-trusted-users='root mail daemon postmaster qmaild mmdf' \
--enable-restrict-trusted=0 \
--enable-sendmail=/usr/sbin/sendmail
改为：
%configure --with-devel --enable-userdb --enable-maildirquota \
--enable-syslog=1 --enable-trusted-users='root mail daemon postmaster qmaild mmdf' \
--enable-restrict-trusted=0 --enable-sendmail=/usr/sbin/sendmail \
--enable-authlib
B、创建安装maildrop rpm
[root@localhost SPECS]# yum -y install pcre-devel
[root@localhost SPECS]# rpmbuild -bb maildrop.spec
[root@localhost SPECS]# cd $RPMS/i386
[root@localhost i386]# rpm -ivh maildrop-2.3.0-1.i386.rpm
C、添加虚似用户及创建目录
[root@localhost i386]# cd 在这里提示已经添加了用户 应该是安装postfix的时候创建的用户
[root@localhost ~]# groupadd -g 1000 vgroup
[root@localhost ~]# useradd -g 1000 -u 1000 -s /sbin/nologin -d /dev/null vuser
编辑/etc/postfix/master.cf ，加入下面的内容：
maildrop unix - n n - - pipe
flags=DRhu user=vuser argv=/usr/bin/maildrop -d ${user}@${nexthop} ${recipient} ${user} ${extension} ${nexthop}
D、创建邮件存储目录
[root@localhost ~]# mkdir -p /home/domains/extmail.org/postmaster
[root@localhost ~]# maildirmake /home/domains/extmail.org/postmaster/Maildir
[root@localhost ~]# chown -R vuser:vgroup /home/domains/
E、测试maildrop
[root@localhost ~]# echo "test" | maildrop -V 10 -d postmaster@360book.com.cn
maildrop: authlib: groupid=1000
maildrop: authlib: userid=1000 这里改成自己相应的
maildrop: authlib:logname=postmaster@extmail.org,
home=/home/domains/extmail.org/postmaster, mail=/home/data/domains/extmail.org/postmaster/Maildir/
maildrop: Changing to /home/data/domains/extmail.org/postmaster
Message start at 0 bytes, envelope sender=postmaster@extmail.org
maildrop: Attempting .mailfilter
maildrop: Delivery complete.
出现上以信息说明authlib，maildrop 工作正常
F、测试pop3
[root@localhost ~]# telnet localhost 110
Trying 127.0.0.1...
Connected to localhost.localdomain (127.0.0.1).
Escape character is '^]'.
+OK Hello there.

[root@localhost ~]# cp -r extmail-1.2 /var/www/extsuite/extmail
[root@localhost ~]# cp -r extman-1.1 /var/www/extsuite/extman
B、配置extmail参数
[root@localhost ~]# cd /var/www/extsuite/extmail/
[root@localhost extmail]# cp webmail.cf.default webmail.cf
修改webmail.cf 下面的选项
SYS_SESS_DIR = /tmp/extmail
SYS_MAILDIR_BASE = /home/domains
SYS_MYSQL_USER = extmail
SYS_MYSQL_PASS = extmail
C、配置extman参数
[root@localhost extmail]# cd /var/www/extsuite/extman/
修改webman.cf 下面的选项：
SYS_MAILDIR_BASE = /home/domains
D、创建session 目录
[root@localhost extman]# mkdir /tmp/{extman,extmail}
[root@localhost extman]# chown vuser:vgroup /tmp/ext*
E、配置后台日志分析工具
[root@localhost addon]# cd /var/www/extsuite/extman/addon/
[root@localhost addon]# cp -r mailgraph_ext /usr/local/
将下面的内容加入/etc/rc.local
/usr/local/mailgraph_ext/mailgraph-init start &
/var/www/extsuite/extman/daemon/cmdserver --daemon &
安装所依懒的软件包
[root@localhost mailgraph_ext]# yum -y install rrdtool perl-rrdtool perl-GD perl-File-Tail
F、启动后台进程
[root@localhost mailgraph_ext]# /usr/local/mailgraph_ext/mailgraph-init start

G、访问extmail/extman
打开浏览器，输入http://your_ip_address/extmail 注意：your_ip_address 为你实际的ip
第一个测试用户为：postmaster 密码：extmail 域：extmail
打开浏览器，输入http://your_ip_address/extman
extman root 用户为：root@360book.com.cn 密码为：extmail*123*
注意：进入系统后要修改密码及找回密码的提示问题、答案。
11.安装dspam clamd
yum install clamd dspam*
进入mysql
create database dspam;
grant all on dspam.* to dspam@localhost identified by 'dspam';
cd /usr/share/dspam/sql/mysql/
修改mysql_objects-4.1.sql virtual_users.sql，在两个文件前添加 use dspam；
mysql -u dspam -p< mysql_objects-4.1.sql
mysql -u dspam -p< virtual_users.sql
crontab -e

[root@localhost ~]#service dspamd start
至此，整个postfix算是安装完毕。重启计算机，访问：http://your ip/extmail/就能直接访问了。
首先说明：这里借鉴了crastyl的博文（http://blog.chinaunix.net/u1/57953/showart.php?id=1211463），然后在此基础上修正了一些错误，安装而成。目前已经上线并使用，现把安装过程总结如下：
一.首先介绍安装环境：
OS：centos5.4最小化安装，选择了组件 base，devlopment libraries development tools editors text-base internet 这几个组件，其他的一概不选。安装系统完毕，直接进行yum update -y &升级。
在终端输入setup命令 选择firewall configuration 将security level 与SELinux 改为disabled，目的是为了避免在安装调试时产生不必要的麻烦，在系统安装完成后，可以自己去调试安全部分，在这里将不作详细介绍。

5、dspam clamd －－提供内容过滤
6、extmail －－一个著名的webmail程序
7、extman －－与extmail集成的后台管理程序
三：组件安装
1、安装AMP
[root@localhost ~]# yum -y install httpd httpd-devel mysql mysql-devel mysql-server php php-xml php-cli php-pdo php-mbstring php-mcrypt php-gd php-common php-devel php-mysql
修改启动配置并启动
[root@localhost ~]# chkconfig --level 345 mysqld on
[root@localhost ~]# chkconfig --level 345 httpd on
[root@localhost ~]# service mysqld start
[root@localhost ~]# service httpd start
2.下载extman（http://www.extmail.org/cgi-bin/download.cgi）
[root@localhost ~]# tar zxf extman-1.1.tar.gz
[root@localhost ~]# cd extman-1.1/docs/
[root@localhost docs]# mysql -uroot <extmail.sql
[root@localhost docs]# mysql -uroot <init.sql
3、RPM 简介
下面我们将采用rpm 的方式安装软件
/usr/src/redhat/SPEC spec 文件夹，通常是rpm文件夹
/usr/src/redhat/RPMS 是生成rpm 的文件，下面还有i368,i486 等子文件夹，一般我们用i386 架构
/usr/src/redhat/SOURCE 源文件文件夹
为了安装时切换目录的方便，我们将目录存放到一个shell变量里。
[root@localhost ~]# export RPMS=/usr/src/redhat/RPMS
[root@localhost ~]# export SOURCE=/usr/src/redhat/SOURCES
[root@localhost ~]# export SPEC=/usr/src/redhat/SPECS
在下面安装过程中，大家要记住cd $RPMS 与cd /usr/src/redhat/RPMS 的目的是一样的，只是shell变量的替换。
4、安装authlib （courier-authlib-0.63.0）
A、安装依懒的包
[root@localhost ~]# yum -y install postgresql-devel expect libtool-ltdl-devel
[root@localhost ~]# wget http://prdownloads.sourceforge.net/courier/courier-authlib-0.63.0.tar.bz2
[root@localhost ~]# tar xjf courier-authlib-0.63.0.tar.bz2
[root@localhost ~]# cd courier-authlib-0.63.0
[root@localhost courier-authlib-0.63.0]# cp courier-authlib.spec $SPEC
[root@localhost courier-authlib-0.63.0]# cd ..
[root@localhost ~]# cp courier-authlib-0.63.0.tar.bz2 $SOURCE
[root@localhost ~]# cd $SPEC
[root@localhost SPECS]# rpmbuild -bb courier-authlib.spec （创建rpm文件）
B、安装生成的rpm
[root@localhost SPECS]# cd $RPMS/i386
[root@localhost i386]# rpm -ivh courier-authlib-0.63.0-1.i386.rpm
[root@localhost i386]# rpm -ivh courier-authlib-devel-0.63.0-1.i386.rpm
[root@localhost i386]# rpm -ivh courier-authlib-mysql-0.63.0-1.i386.rpm
C、配置authlibdaemon
[root@localhost i386]# cd /etc/authlib/
[root@localhost authlib]# mv authdaemonrc authdaemonrc.bak
[root@localhost authlib]# vim authdaemonrc
输入下面的内容：
authmodulelist="authmysql"
authmodulelistorig="authmysql"
daemons=10
authdaemonvar=/var/spool/authdaemon
DEBUG_LOGIN=2
DEFAULTOPTIONS="wbnodsn=1"
LOGGEROPTS=""
D、配置authmysqlrc
[root@localhost authlib]# mv authmysqlrc authmysqlrc.bak
[root@localhost authlib]# vim authmysqlrc
输入下面的内容：
MYSQL_SERVER localhost
MYSQL_USERNAME extmail
MYSQL_PASSWORD extmail
MYSQL_PORT 0
MYSQL_SOCKET /var/lib/mysql/mysql.sock
MYSQL_OPT 0
MYSQL_DATABASE extmail
MYSQL_SELECT_CLAUSE SELECT username,password,"",uidnumber,gidnumber,\
CONCAT('/home/domains/',homedir), \
CONCAT('/home/domains/',maildir), \
quota, \
name \
FROM mailbox \
WHERE username = '$(local_part)@$(domain)'
E、启动authlib
[root@localhost ~]# service courier-authlib start
Starting Courier authentication services: authdaemond
[root@localhost ~]# chmod 777 /var/spool/authdaemon/
5.安装courier-imap
由于courier-imap 不能用root身份生成rpm那么我们新建一个普通用户，并创建一个rpm环境
[root@localhost ~]# useradd yiyou 在这里添加自己的用户
软件包依懒需要安装openldap-server，rpm创建完成后可以删除
[root@localhost ~]# yum -y install openldap-servers
[root@localhost ~]# su - yiyou
[yiyou@localhost ~]$ mkdir -p rpm/{BUILD,RPMS,SOURCES,SPECS,SRPMS}
[yiyou@localhost ~]$ vim ~/.rpmmacros
输入内容：
%_topdir /home/yiyou/rpm
[yiyou@localhost ~]$ wget http://prdownloads.sourceforge.net/courier/courier-imap-4.7.0.tar.bz2
[yiyou@localhost ~]$ cp courier-imap-4.7.0.tar.bz2 rpm/SOURCES/
[yiyou@localhost ~]$ tar xjf courier-imap-4.7.0.tar.bz2
[yiyou@localhost ~]$ cd courier-imap-4.7.0
[yiyou@localhost courier-imap-4.7.0]$ cp courier-imap.spec ../rpm/SPECS/
[yiyou@localhost courier-imap-4.7.0]$ cd ../rpm/SPECS/
编辑courier-imap.spec 将下面的内容：
%if %suse_version
BuildRequires: rpm >= 3.0.5 /usr/bin/sed openldap2 openldap2-devel %([ %{suse_version} -gt 819 ] && echo /usr/include/fam.h)
%else
BuildRequires: rpm >= 4.0.2 sed /usr/include/fam.h openldap-devel openldap-servers
%endif
改为：将此处fam.h 去掉 此处好像没有openldap相关选项 2010-1-12
%if %suse_version 在这里好像提示没有安装openldap-server yum install openldap* 还真没装
BuildRequires: rpm >= 3.0.5 /usr/bin/sed openldap2 openldap2-devel
%else
BuildRequires: rpm >= 4.0.2 sed openldap-devel openldap-servers
%endif
创建rpm
[yiyou@localhost SPECS]$ rpmbuild -bb courier-imap.spec
完成rpm后，输入exit退出当前用户。
[root@localhost ~]# rpm -ivh /home/yiyou/rpm/RPMS/i386/courier-imap-4.7.0-1.i386.rpm
[root@localhost ~]# service courier-imap start
6.安装cyrus-sasl
[root@localhost ~]# yum install -y cyrus-sasl-devel cyrus-sasl-plain cyrus-sasl cyrus-sasl-lib
A.配置sasl2
创建/usr/lib/sasl2/smtpd.conf 文件，输入下面的内容：
pwcheck_method:authdaemond
log_level:3
mech_list:PLAIN LOGIN
authdaemond_path:/var/spool/authdaemon/socket
7、安装postfix 升级至2.6.5
A、下载软件包
[root@localhost i386]# cd
[root@localhost ~]# wget http://ftp.wl0.org/official/2.6/SRPMS/postfix-2.6.5-1.src.rpm
[root@localhost ~]# rpm -ivh postfix-2.6.5-1.src.rpm
[root@localhost ~]# cd $SPEC
编辑postfix.spec 修改下面的选项
%define distribution rhel-5.0
%define with_mysql_redhat 1
%define with_sasl 2
%define with_vda 1
%define with_pcre 1
B、创建rpm
[root@localhost SPECS]# rpmbuild -bb postfix.spec
[root@localhost RPMS]# cd $RPMS/i386
[root@localhost i386]# rpm -ivh postfix-2.6.5-1.rhel5.i386.rpm
C、切换mta
[root@localhost i386]# alternatives --config mta （选择2，postfix）
[root@localhost i386]# rpm -e sendmail
[root@localhost i386]# cd /usr/sbin/
[root@localhost sbin]# mv sendmail sendmail.bak
[root@localhost sbin]# newaliases
[root@localhost sbin]# ln -s sendmail.postfix sendmail
D、配置postfix
[root@localhost ~]# cd /etc/postfix/
[root@localhost postfix]# mv main.cf main.cf.bak
[root@localhost postfix]# vim main.cf
输入下面的内容：
queue_directory = /var/spool/postfix
command_directory = /usr/sbin
daemon_directory = /usr/libexec/postfix
data_directory = /var/lib/postfix
mail_owner = postfix
unknown_local_recipient_reject_code = 550
debug_peer_level = 2
debugger_command =
PATH=/bin:/usr/bin:/usr/local/bin:/usr/X11R6/bin
ddd $daemon_directory/$process_name $process_id & sleep 5
sendmail_path = /usr/sbin/sendmail.postfix
newaliases_path = /usr/bin/newaliases.postfix
mailq_path = /usr/bin/mailq.postfix
setgid_group = postdrop
html_directory = /usr/share/doc/postfix-2.6.5-documentation/html
manpage_directory = /usr/share/man
sample_directory = /etc/postfix
readme_directory = /usr/share/doc/postfix-2.6.5-documentation/readme
alias_database = hash:/etc/postfix/aliases
alias_maps = hash:/etc/postfix/aliases
myhostname = mail.360book.com.cn(修改为自己的域名)
mydomain = 360book.com.cn(修改为自己的域名)
mydestination = $myhostname
smtpd_banner = 360book.com.cn ESMTP Mail System(修改为自己的域名)
message_size_limit = 14680064
virtual_alias_maps = mysql:/etc/postfix/mysql_virtual_alias_maps.cf
virtual_mailbox_base = /home/domains
virtual_mailbox_domains = mysql:/etc/postfix/mysql_virtual_domains_maps.cf
virtual_mailbox_maps = mysql:/etc/postfix/mysql_virtual_mailbox_maps.cf
virtual_mailbox_limit_maps = mysql:/etc/postfix/mysql_virtual_limit_maps.cf
virtual_transport = maildrop
maildrop_destination_recipient_limit = 1
#sasl
smtpd_sasl_auth_enable = yes
smtpd_sasl2_auth_enable = yes
smtpd_sasl_security_options = noanonymous
broken_sasl_auth_clients = yes
smtpd_recipient_restrictions =
permit_mynetworks=,
permit_sasl_authenticated=,
reject_unauth_destination=,
reject_unauth_pipelining=,
reject_invalid_hostname=
dspam_destination_recipient_limit = 1
复制extman/docs 目录的cf 文件到/etc/postfix
[root@localhost postfix]# cp /root/extman-1.1/docs/mysql_virtual_* .
因为配置文件的用户、密码与数据库时一样，所以不用修改。
[root@localhost postfix]# service postfix start
9、安装maildrop
A、下载生成RPM
[root@localhost postfix]# cd
[root@localhost ~]# wget http://prdownloads.sourceforge.net/courier/maildrop-2.3.0.tar.bz2
[root@localhost ~]# cp maildrop-2.3.0.tar.bz2 $SOURCE
[root@localhost ~]# tar xjf maildrop-2.3.0.tar.bz2
[root@localhost ~]# cd maildrop-2.3.0
[root@localhost maildrop-2.3.0]# cp maildrop.spec $SPEC
[root@localhost maildrop-2.3.0]# cd $SPEC
编辑maildrop.spec 把下面：
BuildRequires: /usr/include/fam.h gdbm-devel pcre-devel
改为：
BuildRequires: gdbm-devel pcre-devel
把下面：
%configure --with-devel --enable-userdb --enable-maildirquota \
--enable-syslog=1 --enable-trusted-users='root mail daemon postmaster qmaild mmdf' \
--enable-restrict-trusted=0 \
--enable-sendmail=/usr/sbin/sendmail
改为：
%configure --with-devel --enable-userdb --enable-maildirquota \
--enable-syslog=1 --enable-trusted-users='root mail daemon postmaster qmaild mmdf' \
--enable-restrict-trusted=0 --enable-sendmail=/usr/sbin/sendmail \
--enable-authlib
B、创建安装maildrop rpm
[root@localhost SPECS]# yum -y install pcre-devel
[root@localhost SPECS]# rpmbuild -bb maildrop.spec
[root@localhost SPECS]# cd $RPMS/i386
[root@localhost i386]# rpm -ivh maildrop-2.3.0-1.i386.rpm
C、添加虚似用户及创建目录
[root@localhost i386]# cd 在这里提示已经添加了用户 应该是安装postfix的时候创建的用户
[root@localhost ~]# groupadd -g 1000 vgroup
[root@localhost ~]# useradd -g 1000 -u 1000 -s /sbin/nologin -d /dev/null vuser
编辑/etc/postfix/master.cf ，加入下面的内容：
maildrop unix - n n - - pipe
flags=DRhu user=vuser argv=/usr/bin/maildrop -d ${user}@${nexthop} ${recipient} ${user} ${extension} ${nexthop}
D、创建邮件存储目录
[root@localhost ~]# mkdir -p /home/domains/extmail.org/postmaster
[root@localhost ~]# maildirmake /home/domains/extmail.org/postmaster/Maildir
[root@localhost ~]# chown -R vuser:vgroup /home/domains/
E、测试maildrop
[root@localhost ~]# echo "test" | maildrop -V 10 -d postmaster@360book.com.cn
maildrop: authlib: groupid=1000
maildrop: authlib: userid=1000 这里改成自己相应的
maildrop: authlib:logname=postmaster@extmail.org,
home=/home/domains/extmail.org/postmaster, mail=/home/data/domains/extmail.org/postmaster/Maildir/
maildrop: Changing to /home/data/domains/extmail.org/postmaster
Message start at 0 bytes, envelope sender=postmaster@extmail.org
maildrop: Attempting .mailfilter
maildrop: Delivery complete.
出现上以信息说明authlib，maildrop 工作正常
F、测试pop3
[root@localhost ~]# telnet localhost 110
Trying 127.0.0.1...
Connected to localhost.localdomain (127.0.0.1).
Escape character is '^]'.
+OK Hello there.
