RedHat el5.0 搭建 Postfix 邮件服务器系统
(postfix+cyrus-sasl2+courier-authlib+courier-imap+extmail+maildrop)
一、系统环境
操作系统：rhel-5.2
所需软件（按网上以前的文档，好多版本都找不到，只能找相近的，下面都是在实验后都可以使用的包2010/10/27）
httpd-2.2.0.tar.bz2 架设web用于extman的后台管理，extmail 的web邮件收发
php-5.2.14.tar.gz Php 解释器，extman & extmail 需要使用php
mysql-5.1.37.tar.gz 用于存储虚拟域、虚拟账户信息
postfix-2.4.5.tar.gz 邮件服务器系统的smtp服务器，充当MTA
cyrus-sasl-2.1.22.tar.gz 用于实现身份验证的 smtp 服务器
courier-authlib-0.58.tar.bz2 实现带验证的 pop3 服务器
courier-imap-4.2.0.tar.bz2 用于实现 pop3、imap 收邮件功能
extmail-1.1.0.tar.gz 用于实现 webmail
extman-0.2.5.tar.gz 用于邮件服务器的后台管理
openssl-0.9.8e.tar.gz 提供安全的邮件服务器连接
DBD-mysql-2.9008.tar.gz 用于解决依赖关系，extmail 将会用到
Unix-Syslog-1.1.tar.gz 用于解决依赖关系，extmail 将会用到
BerkeleyDB（db-4.5.20.tar.gz） 在编译postfix要使用
maildrop-2.0.4.tar.bz2 用来代替postfix自带的MDA,是一个带有过滤功能的MDA
pcre-7.2.tar.bz2 用于安装maildrop
系统禁用 selinux
二、软件安装
1、安装apache
tar zxvf httpd-2.2.0.tar.gz
cd httpd-2.2.0
./configure --prefix=/usr/local/apache --enable-so
make
make install
安装最主要的是mod_so模块httpd –l检测mod_so.c，目的是为了以模块方式加载php
2、安装 mysql
tar xvf mysql-5.1.37.tar.gz
cd mysql-5.1.37
./configure -prefix=/usr/local/mysql
make&&make install
useradd mysql
cp support-files/my-medium.cnf /etc/my.cnf
cd /usr/local/mysql
/usr/local/mysql/bin/mysql_install_db --user=mysql //初始化数据库
chown -R root .
chown -R mysql var
chgrp -R mysql .
echo "/usr/local/mysql/lib/mysql">>/etc/ld.so.conf
ldconfig
echo "export PATH=$PATH:/usr/local/mysql/bin">>/etc/profile
source /etc/profile
上面这几行红色的字，必须要添加，否则在安装过程中会出现很多错误，还在注意在/tmp目录下是否存在 mysql.sock 这个文件,如果没有的话，就要做一个链接了，避免mysql在启动时报错
复制一个编译目录的脚本，以使 mysql 每次启动时都能自动运行,回到编译的目录mysql-5.1.37
cp support-files/mysql.server /etc/rc.d/init.d/mysqld
chkconfig --add mysqld
chkconfig --level 35 mysqld on
service mysqld start
3、安装php
tar –xvf php-5.2.14.tar.gz
cd php-5.2.14
./configure -prefix=/usr/local/php -with-apxs2=/usr/local/apache/bin/apxs -with-mysql=/usr/local/mysql
make&&make install
cp php.ini-dist /usr/local/php/lib/php.ini
修改apache的配置文件 httpd.conf加上"AddType application/x-httpd-php .php，定位至 DirectoryIndex index.html ，修改为： DirectoryIndex index.php index.html
在目录/usr/local/apache/htdocs下创建一个最简单的php测试文件，其内容为：
vi test.php
<?
phpinfo();
?>
检查一下apache配置文件是否正确（/usr/local/apache/bin/apachectl -t），输出"Syntax OK"后就可以启动apache服务（/usr/local/apache/bin/apachectl start）。
在浏览器上测试test.php，会看到php的信息
4、安装 openssl
tar zxvf openssl-0.9.8e.tar.gz
./config shared zlib
make
make test
make install
mv /usr/bin/openssl /usr/bin/openssl.OFF
mv /usr/include/openssl /usr/include/openssl.OFF
rm -rf /usr/lib/libssl.so
ln -s /usr/local/ssl/bin/openssl /usr/bin/openssl
ln -s /usr/local/ssl/include/openssl /usr/include/openssl
ln -sv /usr/local/ssl/lib/libssl.so.0.9.8 /usr/lib/libssl.so
echo "/usr/local/ssl/lib" >> /etc/ld.so.conf
ldconfig
检查是否安装 openssl
openssl version
OpenSSL 0.9.8e 23 Feb 2007
5、安装 courier-authlib
tar jxvf courier-authlib-0.58.tar.bz2
cd courier-authlib-0.58
. /configure --prefix=/usr/local/authlib --without-authpam --without-authldap --without-authpwd --without-authpgsql --with-authmysql --without-authshadow --without-authvchkpw --with-mysql-libs=/usr/local/mysql/lib/mysql --with-mysql-includes=/usr/local/mysql/include/mysql --with-redhat CFLAGS="-march=i686 -O2 -fexpensive-optimizations" CXXFLAGS="-march=i686 -O2 -fexpensive-optimizations"
make && make install
chmod 755 /usr/local/authlib/var/spool/authdaemon
cp /usr/local/authlib/etc/authlib/authdaemonrc.dist /usr/local/authlib/etc/authlib/authdaemonrc
cp /usr/local/authlib/etc/authlib/authmysqlrc.dist /usr/local/authlib/etc/authlib/authmysqlrc
vi /usr/local/courier-authlib/etc/authlib/authdaemonrc
authmodulelist="authmysql"
authmodulelistorig="authmysql"
daemons=10
vi /usr/localcourier-authlib/etc/authlib/authmysqlrc
MYSQL_SERVER localhost
MYSQL_PORT 3306
MYSQL_USERNAME extmail
MYSQL_PASSWORD extmail
MYSQL_SOCKET /tmp/mysql.sock
MYSQL_DATABASE extmail
MYSQL_USER_TABLE mailbox
MYSQL_CRYPT_PWFIELD password
MYSQL_UID_FIELD '2525'
MYSQL_GID_FIELD '2525'
MYSQL_LOGIN_FIELD username
MYSQL_HOME_FIELD concat('/var/mailbox/',homedir)
MYSQL_NAME_FIELD name
MYSQL_MAILDIR_FIELD concat('/var/mailbox/',maildir)
注：其中 2525，2525为postfix用户的UID和GID(这里可先设置id号，当建postfix用户时，可指定uid,gid要注意对应即可,这个文件中不能出现空格，或者会出现错误
设置 courier-authlib 自启动
cp courier-authlib.sysvinit /etc/init.d/courier-authlib
chmod 755 /etc/init.d/courier-authlib
chkconfig --add courier-authlib
chkconfig --level 2345 courier-authlib on
echo "/usr/local/authlib/lib/courier-authlib" >> /etc/ld.so.conf
ldconfig
service courier-authlib start
6、安装 courier-sasl
删除以前的rpm包以及相关目录,系统自带的与authlib配合不好
rpm –qa | grep sasl 显示出已安装的都要删除
rpm -e --nodeps cyrus-sasl-2.1.10-4 cyrus-sasl-plain-2.1.10-4 cyrus-sasl-md5-2.1.10-4 cyrus-sasl-devel-2.1.10-4 …
rm -rf /usr/lib/sasl
rm -rf /usr/lib/sasl2
tar –xvf cyrus-sasl-2.1.22.tar.gz (使用2.1.21版本，在make时报错，网上查要sasl.patch补丁，也没启作用，最后还是选择了2.1.22版本)
cd cyrus-sasl-2.1.22
./configure --enable-plain --enable-cram --enable-digest --enable-login --enable-sql --disable-anon --disable-ntlm --disable-gssapi --disable-krb4 --disable-otp --disable-srp --disable-srp-setpass --with-authdaemond=/usr/local/authlib/var/spool/authdaemon/socket
--with-mysql=/usr/local/mysql --with-mysql-includes=/usr/local/mysql/include/mysql --with-mysql-libs=/usr/local/mysql/lib/mysql
make
make install
ln -s /usr/local/lib/sasl2 /usr/lib/sasl2
增加"/usr/local/lib"到你的"/etc/ld.so.conf"，并执行ldconfig命令。
vi /usr/local/lib/sasl2/smtpd.conf
pwcheck_method: authdaemond
log_level: 3
mech_list: PLAIN LOGIN
authdaemond_path:/usr/local/authlib/var/spool/authdaemon/socket
注意，这个文件的编辑不要多写一个空格，否则会出现smtp验证不过的问题
7、安装 Berkeley-DB
tar zxvf db-4.5.20.tar.gz
cd db-4.5.20/build_unix
../dist/configure —prefix=/usr/local/BerkeleyDB
make
make install
mv /usr/inculde/db4 /usr/inculde/db4.OFF
rm -rf /usr/inculde/db_cxx.h
rm -rf /usr/inculde/db.h
rm -rf /usr/inculde/db_185.h
ln -s /usr/local/BerkeleyDB/include /usr/include/db4
ln -s /usr/local/BerkeleyDB/include/db.h /usr/include/db.h
ln -s /usr/local/BerkeleyDB/include/db_cxx.h /usr/include/db_cxx.h
echo "/usr/local/BerkeleyDB/lib" >> /etc/ld.so.conf
ldconfig
8、安装 postfix
groupadd -g 2525 postfix
useradd -g postfix -u 2525 -s /sbin/nologin -M postfix
groupadd -g 2526 postdrop
useradd -g postdrop -u 2526 -s /bin/false -M postdrop
service sendmail stop
mv /usr/sbin/sendmail /usr/sbin/sendmail.OFF
mv /usr/bin/mailq /usr/bin/mailq.OFF
mv /usr/bin/newaliases /usr/bin/newaliases.OFF
tar zxvf postfix-2.4.5.tar.gz
cd postfix-2.4.5
make makefiles 'CCARGS=-DHAS_MYSQL -I/usr/local/mysql/include/mysql -DUSE_SASL_AUTH -DUSE_CYRUS_SASL -I/usr/local/sasl2/include/sasl -I/usr/local/BerkeleyDB/include -DUSE_TLS -I/usr/local/ssl/include/openssl ' 'AUXLIBS=-L/usr/local/mysql/lib/mysql -lmysqlclient -lz -lm -L/usr/local/sasl2/lib -lsasl2 -L/usr/local/BerkeleyDB/lib -L/usr/local/ssl/lib -lssl -lcrypto'
make
make install
tempdir: [/root/ postfix-2.4.5]
config_directory: [/etc/postfix]
daemon_directory: [/usr/libexec/postfix]
command_directory: [/usr/sbin]
queue_directory: [/var/spool/postfix]
sendmail_path: [/usr/sbin/sendmail]
newaliases_path: [/usr/bin/newaliases]
mailq_path: [/usr/bin/mailq]
mail_owner: [postfix]
setgid_group: [postdrop]
html_directory: [no]
manpages: [/usr/local/man]
readme_directory: [no]
上面的选项全部保持默认，直接回车即可。
事先要执行：echo “/usr/local/ssl/lib” >> /etc/ld.so.conf
ldconig 避免出现错误
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：
newaliases
配置 postfix
vi /etc/postfix/main.cf
myhostname = mail.wlq.com
mydomain = wlq.com
myorigin = $mydomain
inet_interfaces = all
mynetworks = 192.168.1.0/24, 127.0.0.0/8
#================Virtual Setting ====================
virtual_mailbox_base = /var/mailbox/
virtual_mailbox_maps= mysql:/etc/postfix/mysql/mysql_virtual_mailbox_maps.cf
virtual_mailbox_domains=mysql:/etc/postfix/mysql/mysql_virtual_domains_maps.cf
virtual_alias_domains =
virtual_alias_maps = mysql:/etc/postfix/mysql/mysql_virtual_alias_maps.cf
virtual_uid_maps = static:2525
virtual_gid_maps = static:2525
virtual_transport = virtual
maildrop_destination_recipient_limit = 1
maildrop_destination_concurrency_limit = 1
#=================Quota Setting ====================
message_size_limit = 14336000
virtual_mailbox_limit = 20971520
virtual_create_maildirsize = yes
virtual_mailbox_extended = yes
virtual_mailbox_limit_maps
mysql:/etc/postfix/mysql/mysql_virtual_mailbox_limit_maps.cf
virtual_mailbox_limit_override = yes
virtual_maildir_limit_message = Sorry,the user's maildir has overdrawn his diskspace quota,please Tidy your mailbox and try again later.
virtual_overquota_bounce = yes
#=================== Cyrus-sasl=====================
broken_sasl_auth_clients = yes
smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_invalid_hostname,reject_non_fqdn_hostname,
reject_unknown_sender_domain,reject_non_fqdn_sender,
reject_non_fqdn_recipient,reject_unknown_recipient_domain, reject_unauth_pipelining,
reject_unauth_destination, permit
smtpd_sasl_auth_enable = yes
smtpd_sasl_local_domain = $myhostname
smtpd_sasl_security_options = noanonymous
smtpd_sasl_application_name = smtpd
smtpd_banner = Welcome to our $myhostname ESMTP, Warning:Version not Available!
local_recipient_maps = （也要填加这一条，我也是最后在web界面发邮件时老报local_recipient的错，填加这一条后就好了）
# mkdir -p /etc/postfix/mysql
cd /etc/postfix/mysql
vi mysql_virtual_alias_maps.cf
user = extmail
password = extmail
hosts = localhost
dbname = extmail
table = alias
select_field = goto
where_field = address
vi mysql_virtual_mailbox_limit_maps.cf
user = extmail
hosts = localhost
dbname = extmail
table = mailbox
select_field = quota
where_field = username
vi mysql_virtual_domains_maps.cf
user = extmail
password = extmail
hosts = localhost
dbname = extmail
table = domain
select_field = description
where_field = domain
vi mysql_virtual_mailbox_maps.cf
user = extmail
password = extmail
hosts = localhost
dbname = extmail
table = mailbox
select_field = maildir
where_field = username
9、安装 Courier-IMAP
tar –xvjf courier-imap-4.2.0.tar.bz2
cd courier-imap-4.2.0
./configure --prefix=/usr/local/imap --with-redhat --enable-unicode --disable-root-check --with-trashquota CPPFLAGS='-I/usr/local/ssl/include/openssl -I/usr/local/authlib/include' LDFLAGS='-L/usr/local/authlib/lib/courier-authlib' COURIERAUTHCONFIG='/usr/local/authlib/bin/courierauthconfig'
make
make install
cp /usr/local/imap/etc/imapd.dist /usr/local/imap/etc/imapd
cp /usr/local/imap/etc/imapd-ssl.dist /usr/local/imap/etc/imapd-ssl
cp /usr/local/imap/etc/pop3d.dist /usr/local/imap/etc/pop3d
cp /usr/local/imap/etc/pop3d-ssl.dist /usr/local/imap/etc/pop3d-ssl
vi /usr/local/imap/etc/pop3d
POP3DSTART=YES
注：如果你想为用户提供 IMAP 服务，则需在"/usr/local/courier-imap/etc/imapd"文件中设置"IMAPDSTART=yes"；其它类同；
新建虚拟用户邮箱所在的目录，并将其权限赋予 postfix 用户：
mkdir -p /var/mailbox
chown -R postfix /var/mailbox
cp courier-imap.sysvinit /etc/rc.d/init.d/imapd
chmod 755 /etc/rc.d/init.d/imapd
chkconfig --add imapd
chkconfig --level 2345 imapd on
service imapd start
10、安装 extmail
tar –xvf extmail-1.1.0.tar.gz
mkdir -pv /var/www/extsuite
mv extmail-1.1.0 /var/www/extsuite/extmail
cp /var/www/extsuite/extmail/webmail.cf.default /var/www/extsuite/extmail/webmail.cf
vi /var/www/extsuite/extmail/webmail.cf (下列选项为修改后的)
SYS_MESSAGE_SIZE_LIMIT = 5242880 用户可以发送的最大邮件
SYS_USER_LANG = zh_CN
SYS_MAILDIR_BASE = /var/mailbox/ 用户邮件的存放目录
SYS_MYSQL_USER = extmail
SYS_MYSQL_PASS = extmail
以上两句句用来设置连接数据库服务器所使用用户名、密码和邮件服务器用到的数据库
SYS_MYSQL_HOST = localhost 指明数据库服务器主机名
SYS_MYSQL_SOCKET = /tmp/mysql.sock 连接数据库的 sock 文件位置
SYS_MYSQL_TABLE = mailbox
SYS_MYSQL_ATTR_USERNAME = username
SYS_MYSQL_ATTR_DOMAIN = domain
SYS_MYSQL_ATTR_PASSWD = password
以上用来指定验正用户登录里所用到的表，以及用户名、域名和用户密码分别对应的表中列的名称
SYS_AUTHLIB_SOCKET = /usr/local/courier-authlib/var/spool/authdaemon/socket
指明 authdaemo socket 文件的位置
apache 相关配置
[root @test root] # vi /usr/local/apache/conf/httpd.conf
将 User daemon
Group daemon
改为
User postfix
Group postfix
将 Include conf/extra/httpd-vhosts.conf
前的注释去掉，打开 apache 的虚拟主机功能。
# virtual hosts
Include conf/extra/httpd-vhosts.conf
vi /usr/local/apache/conf/extra/httpd-vhosts.conf
<VirtualHost *:80>
ServerName mail.wlq.com
DocumentRoot /var/www/extsuite/extmail/html/
ScriptAlias /extmail/cgi /var/www/extsuite/extmail/cgi
Alias /extmail /var/www/extsuite/extmail/html
</VirtualHost>
<Directory "/var/www/extsuite">
Options Indexes FollowSymLinks
AllowOverride None
Order allow,deny
Allow from all
</Directory>
11、安装 Unix-Syslog-1.1.tar.gz和DBD-mysql-2.9008.tar.gz
extmail 将会用到 perl 的 DBD::Mysql 和 Unix::syslogd 功能， 您可以去http://search.cpan.org下载
tar -zxvf Unix-Syslog-1.1.tar.gz
cd Unix-Syslog-1.1
perl Makefile.PL
make
make install
tar –xvzf DBD-mysql-2.9008.tar.gz
cd DBD-mysql-2.9008
perl Makefile.PL
make && make install
到此为止，Webmail 已经可以使用了，可以在浏览器中输入指定的虚拟主机的 名称进行访问，http://mail.wlq.com (做测试可以事先在机子上解析这个域名，加到hosts，也可以搭个dns)
12、安装extman-0.2.5.tar.gz
tar –xvzf extman-0.2.5.tar.gz
mv extman-0.2.5 /var/www/extsuite/extman
vi /var/www/extsuite/extman/webman.cf (修改后的选项)
SYS_MAILDIR_BASE = /var/mailbox/
SYS_MYSQL_SOCKET = /tmp/mysql.sock
使用 extman 源码目录下 docs 目录中的 extmail.sql 和 init.sql 建立数据库：
cd /var/www/extsuite/extman/docs
/usr/local/mysql/bin/mysql -u root < extmail.sql
/usr/local/mysql/bin/mysql -u root -p < init.sql
Enter password: 输入 mysql root 用户的密码
修改 cgi 目录的属主：
chown -R postfix.postfix /var/www/extsuite/extman/cgi/
如果 extman 访问数据库权限不足的话，可采用以下命令将新生成的数据库赋予 webman
/usr/local/mysql/bin/mysql
mysql> use extmail;
mysql> GRANT all privileges on extmail.* TO webman@localhost IDENTIFIED BY 'webman';
mysql> GRANT all privileges on extmail.* TO webman@127.0.0.1 IDENTIFIED BY 'webman';
mysql> quit
在 apache 的虚拟主机配置文件中 Extmail 的虚拟主机部分，再添加如下两行：
vi /usr/local/apache/conf/extra/httpd-vhosts.conf
ScriptAlias /extman/cgi /var/www/extsuite/extman/cgi
Alias /extman /var/www/extsuite/extman/html
启动所有服务： （已启动的可以重启下）
service mysqld start
/usr/local/apache/bin/apachectl start
service courier-authlib start
service imapd start
postfix start
在 IE 浏览器中输入http://mail.wlq.com/extman ,进入邮件服务器的后台,添加域与添加 用户邮箱。默认管理帐号为：root@extmail.org 密码为：extmail*123*。我这里添加了一 个 wlq.com 域和一个用户邮箱:ceshi@wlq.com。至于开通邮件服务器自动注册邮箱服务，只需要编辑该域，将"允许自由注册邮箱"前面打上勾即可。
第一次登录可能出现如下错误：
这是由于 /tmp/extman 目录的原因，新建之即可，然后将该目录权限设置为 777
(1) 如果您安装后无法正常显示校验码，安装 perl-GD 模块会解决这个问题。如果想简单您 可 以 到 以 下 地 址 下 载 适 合 您 的包 ， 安 装平 台 的 rpm即可 http://dries.ulyssis.org/rpm/packages/perl-GD/info.html （我用的perl-GD-2.35-1.el5.rf.i386.rpmperl-GD-2.35-1.el5.rf.i386.rpm）
(2) extman-0.2.2 自带了图形化显示日志的功能；此功能需要 rrdtool 的支持，您需要安装
这些模块才可能正常显示图形日志。
接下来安装图形日志的运行所需要的软件包 Time::HiRes、File::Tail 和 rrdtool，其中前两个
包 您 可 以 去 http://search.cpan.org 搜 索 并 下 载 获 得 ， 后 一 个 包 您 可 以 到 http://oss.oetiker.ch/rrdtool/pub/?M=D 下载获得； 注意安装顺序不能改换。
下面安装 Time::HiRes 、File::Tail 和 rrdtool
tar zxvf Time-HiRes-1.9721.tar.gz
cd Time-HiRes-1.9721
perl Makefile.PL
make
make test
make install
tar zxvf File-Tail-0.99.3.tar.gz
cd File-Tail-0.99.3
perl Makefile.PL
make
make test
make install
在安装 rrdtool 之前，就确定你的系统中是否已经安装 tcl、tcl-devel、libart、libart-devel
tar zxvf rrdtool-1.2.23.tar.gz
cd rrdtool-1.2.23
./configure --prefix=/usr/local/rrdtool
make
make install
创建必要的符号链接(Extman 会到这些路径下找相关的库文件)
ln –s /usr/local/rrdtool/lib/perl/5.8.8/i386-linux-thread-multi/auto/RRDs/RRDs.so /usr/lib/perl5/5.8.5/i386-linux-thread-multi/
ln -sv /usr/local/rrdtool/lib/perl/5.8.8/RRDp.pm /usr/lib/perl5/5.8.8
ln -sv /usr/local/rrdtool/lib/perl/5.8.8/i386-linux-thread-multi/RRDs.pm /usr/lib/perl5/5.8.8
复制 mailgraph_ext 到/usr/local，并启动
cp -r /var/www/extsuite/extman/addon/mailgraph_ext /usr/local
/usr/local/mailgraph_ext/mailgraph-init start
/usr/local/mailgraph_ext/qmonitor-init start
添加到自动启动
echo "/usr/local/mailgraph_ext/mailgraph-init start" >> /etc/rc.local
echo "/usr/local/mailgraph_ext/qmonitor-init start" >> /etc/rc.local
接下来就可以到 extman里面的全部东西了
http://mail.wlq.com/extman
测试：在web界面中收信，发信都正常，用telnet测试下smtp和pop3
用户名：ceshi@wlq.com 密码：ceshi
用下列命令获得BASE64 编码
[root@mail ~]# perl -e 'use MIME::Base64;print encode_base64("ceshi\@wlq.com")'
Y2VzaGlAd2xxLmNvbQ==
[root@mail ~]# perl -e 'use MIME::Base64;print encode_base64("ceshi")'

Cleartext Password: ceshi
Options: (none)
13、安装maildorp-2.0.4.tar.bz2
首先将courier-authlib的头文件及库文件链接至/usr目录(编译maildrop时会到此目录下找此些相关 的文件):
ln -sv /usr/local/authlib/bin/courierauthconfig /usr/bin
ln -sv /usr/local/authlib/include/* /usr/include
maildrop需要pcre的支持，因此，接下来将首先安装pcre
tar jxvf pcre-7.2.tar.bz2
cd pcre-7.2
./configure
make
make check
make install
groupadd -g 1001 vmail
useradd -g vmail -u 1001 -M -s /sbin/nologin vmail
tar jxvf maildrop-2.0.4.tar.bz2
cd maildrop-2.0.4
./configure --enable-sendmail=/usr/sbin/sendmail --enable-trusted-users='root vmail' --enable-syslog=1 --enable-maildirquota --enable-maildrop-uid=1001 --enable-maildrop-gid=1001 --with-trashquota --with-dirsync
make
make install
安装过程中要有这个错误/usr/bin/install: cannot stat `makedat/makedatprog': No such file or directory时，应检查gbdm和gbdm-devel包，安这两包后就可以了
检查安装结果，请确保有"Courier Authentication Library extension enabled."一句出现：
# maildrop -v
maildrop 2.0.4 Copyright 1998-2005 Double Precision, Inc.
GDBM extensions enabled.
[color=DarkOrange]Courier Authentication Library extension enabled.[/color]
Maildir quota extension enabled.
This program is distributed under the terms of the GNU General Public

vi /etc/maildroprc （新建）
logfile "/var/log/maildrop.log"
touch /var/log/maildrop.log
chown vmail.vmail /var/log/maildrop.log
配置 postfix，
vi /etc/postfix/master.cf
启用下面这两行，将前面的注释符号去掉
maildrop unix - n n - -
pipe flags=DRhu user=vmail argv=/usr/local/maildrop/bin/maildrop -d ${recipient}
vi /etc/postfix/main.cf
将 virtual_transport = virtual 修改为 virtual_transport = maildrop
virtual_uid_maps = static:1001
virtual_gid_maps = static:1001
vi /usr/local/ authlib/etc/authlib/authmysqlrc
下面两个修改为
MYSQL_UID_FIELD ‘1001’
MYSQL_GID_FIELD ‘1001’
vi /usr/local/apache/conf/httpd.conf (下面选项修改为如下的值)
User vmail
Group vmail
修改用户邮件所在目录 /var/mailbox 和 extman 的临时目录 /tmp/extman 的属主和属组
chown -R vmail.vmail /var/mailbox
chown -R vmail.vmail /tmp/extman
重新启动 apache 和 postfix，在web界面发送一份邮件测试，tail -f /var/log/maillog中看到的日志，
Oct 27 09:45:05 mail postfix/pipe[21265]: 71D4C3674EE: to=<ceshi@wlq.com>, relay=maildrop, delay=486, delays=485/0.08/0/0.25, dsn=4.3.0, status=deferred (temporary failure. Command output: /usr/local/bin/maildrop: Unable to open mailbox. )
Oct 27 09:45:35 mail maildrop[21273]: Unable to open mailbox.
报错，在网上找了找，发现在/etc/maildroprc中少了一行，加了这行，测试就OK
[root@mail mailbox]# vi /etc/maildroprc
logfile "/var/log/maildrop.log"
to "$HOME/Maildir" （新加的一行）
再测试：tail –f /var/log/maillog
Oct 27 09:47:16 mail postfix/pipe[21306]: 8D2D03674F9: to=<ceshi@wlq.com>, relay=maildrop, delay=0.96, delays=0.2/0.05/0/0.7, dsn=2.0.0, status=sent (delivered via maildrop service)
Oct 27 09:47:16 mail postfix/qmgr[20843]: 8D2D03674F9: removed
[root@mail mailbox]# tail -f /var/log/maildrop.log
Date: Wed Oct 27 09:46:33 2010
From:
Subj:
File: /var/mailbox/wlq.com/ceshi/Maildir
测试成功，说明Maildrop安装成功，到此为止，邮件系统的搭建基本完成，接下来安装反病毒和反垃圾邮件的相关组件，下篇接着弄。
非常感谢网上搭建邮件系统的前辈们，这也是根据他们的文档自己做了一次搞下来的，同时自己在做的过程中也记录下做个备份。
