(4)配置postfix以支持虚拟域和虚拟用户
a、编辑/etc/postfix/main.cf，添加如下内容：
########################Virtual Mailbox Settings########################
virtual_mailbox_base = /var/mailbox
virtual_mailbox_maps = mysql:/etc/postfix/mysql_virtual_mailbox_maps.cf
virtual_mailbox_domains= mysql:/etc/postfix/mysql_virtual_domains_maps.cf
virtual_alias_domains =
virtual_alias_maps = mysql:/etc/postfix/mysql_virtual_alias_maps.cf
virtual_uid_maps = static:501 //501为你添加的postfix用户uid
virtual_gid_maps = static:501 //501为你添加的postfix组gid
virtual_transport = virtual
maildrop_destination_recipient_limit = 1
maildrop_destination_concurrency_limit = 1
要注意的地方是 virtual_uid_maps及virtual_gid_maps的值，它是postfix用户uid和postfix组的gid,与前面的文件/usr/local/authlib/etc/authlib/authmysqlrc的"MYSQL_UID_FIELD""MYSQL_GID_FIELD"一定要保持一致
##########################QUOTA Settings######################## message_size_limit = 14336000
virtual_mailbox_limit = 20971520
virtual_create_maildirsize = yes
virtual_mailbox_extended = yes
virtual_mailbox_limit_maps = mysql:/etc/postfix/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
b、添加为支持虚拟域和虚拟用户所用到的配置文件,以下4个配置文件是不存在的,需要创建. 编辑/etc/postfix/mysql_virtual_alias_maps.cf ，添加如下内容：
user = extmail //虚拟用户名
password = extmail //虚拟用户密码
hosts = localhost //虚拟的IP
dbname = extmail //虚拟的数据库
table = alias //虚拟的数据库表
select_field = goto
where_field = address
c、 编辑/etc/postfix/mysql_virtual_domains_maps.cf ，添加如下内容：
user = extmail
password = extmail
hosts = localhost
dbname = extmail
table = domain
select_field = description
where_field = domain
d、 编辑/etc/postfix/mysql_virtual_mailbox_limit_maps.cf ，添加如下内容：
user = extmail
password = extmail
hosts = localhost
dbname = extmail
table = mailbox
select_field = quota
where_field = username
e、 编辑/etc/postfix/mysql_virtual_mailbox_maps.cf ，添加如下内容：
user = extmail
password = extmail
hosts = localhost
dbname = extmail
table = mailbox
select_field = maildir
where_field = username
说明： 1、这里用到的数据库及用户的建立可以后文中的extmail说明部分来实现，您可以参照那一部分来理解这里指定的数据库及其用户名等；
2、以上新建文件亦可以从extman安装文件中获得，您也可以由此不用手动输入；
3、虚拟用户邮箱目录我这里沿用了/var/mailbox，你可以指定为别的目录，比如常见到的/var/spool/mail，或者/home/domains等；但如果这里做了修改，请在后文中用到时作了相应的修改；
#chmod +x /etc/init.d/postfix
#chkconfig --add postfix
#chkconfig --level 35 postfix on
#service postfix start
#tar -jxvf courier-imap-4.5.1.tar.bz2
#cd courier-imap-4.5.1
#./configure --prefix=/usr/local/courier-imap --enable-unicode --disable-root-check --with-trashquota --without-ipv6
CPPFLAGS='-I/usr/local/courier-authlib/include' LDFLAGS='-L/usr/local/courier-authlib/lib/courier-authlib'
COURIERAUTHCONFIG='/usr/local/courier-authlib/bin/courierauthconfig'
#make
#make install
复制配置文件
#cd /usr/local/courier-imap/
#cp ./etc/imapd.dist ./etc/imapd
#cp ./etc/imapd-ssl.dist ./etc/imapd-ssl
#cp ./etc/pop3d.dist ./etc/pop3d
#cp ./etc/pop3d-ssl.dist ./etc/pop3d-ssl
配置Courier-IMAP，为用户提供pop3服务：
#vi ./etc/pop3d
POP3DSTART=YES
注意: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；
设置开机启动
#cd /root/tools/postfix/courier-imap-4.5.1/
#cp courier-imap.sysvinit /etc/init.d/courier-imapd
#chmod 755 /etc/init.d/courier-imapd
#chkconfig --add courier-imapd
#chkconfig --level 35 courier-imapd on
#service courier-imapd start
新建虚拟用户邮箱所在的目录
新建虚拟用户邮箱所在的目录，并将其权限赋予postfix用户：
#mkdir –pv /var/mailbox
#chown -R postfix /var/mailbox
重新配置SMTP 认证
#vi /usr/local/sasl2/lib/sasl2/smtpd.conf
确保其为以下内容:
pwcheck_method: authdaemond
log_level: 3
mech_list:PLAIN
LOGIN authdaemond_path:/usr/local/courier-authlib/var/spool/authdaemon/socket
重新启动sasal服务
#killall -9 saslauthd
#/usr/local/sasl2/sbin/saslauthd -a shadow pam
(extmail 用于实现web mail)
(extman 用于邮件服务器的后台管理)
#tar -zxvf extmail-1.0.9.tar.gz
#cp -rf extmail-1.0.9 /usr/local/apache/htdocs/extmail
#cd /usr/local/apache/htdocs/extmail
#cp webmail.cf.default webmail.cf
#vi webmail.cf
部分修改选项的说明：
SYS_CONFIG = /usr/local/apache/htdocs/extmail/
SYS_LANGDIR = /usr/local/apache/htdocs/extmail/lang
SYS_TEMPLDIR = /usr/local/apache/htdocs/extmail/html
SYS_MESSAGE_SIZE_LIMIT = 5242880 //用户可以发送的最大邮件
SYS_USER_LANG = en_US //语言选项，
可改作： SYS_USER_LANG = zh_CN
SYS_MAILDIR_BASE = /home/domains //此处即为您在前文所设置的用户邮件的存放目录
可改作： SYS_MAILDIR_BASE = /var/mailbox
SYS_MYSQL_USER = db_user
SYS_MYSQL_PASS = db_pass
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，这里修改为：
SYS_MYSQL_USER = extmail
SYS_MYSQL_PASS = extmail
SYS_MYSQL_HOST = localhost //指明数据库服务器主机名,这里默认即可 SYS_MYSQL_SOCKET = /var/lib/mysql/mysql.sock //连接数据库的sock文件位置
这里修改为： SYS_MYSQL_SOCKET = /tmp/mysql.sock
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这里默认即可
SYS_AUTHLIB_SOCKET = /var/spool/authdaemon/socket //此句用来指明authdaemo socket文件的位置这里修改为：SYS_AUTHLIB_SOCKET = /usr/local/courier-authlib/var/spool/authdaemon/socket
#tar -zxvf extman-1.0.0.tar.gz
#cp -r extman-1.0.0 /usr/local/apache/htdocs/extman
#cd /usr/local/apache/htdocs/extman
#mkdir /var/tmp/extman
#chown postfix.postfix /var/tmp/extman
#chown -R postfix.postfix cgi
#vi webman.cf
修改如下配置
SYS_CONFIG = /usr/local/apache/htdocs/extman/
SYS_LANGDIR = /usr/local/apache/htdocs/extman/lang
SYS_TEMPLDIR = /usr/local/apache/htdocs/extman/html
SYS_MAILDIR_BASE = /home/domains //此处即为您在前文所设置的用户邮件的存放目录
可改作： SYS_MAILDIR_BASE = /var/mailbox/
SYS_MYSQL_SOCKET = /var/lib/mysql/mysql.sock
此处修改为： SYS_MYSQL_SOCKET = /tmp/mysql.sock
SYS_SESS_DIR = /var/tmp/extman/
SYS_CAPTCHA_ON = 0 （关闭显示校验码或者安装perl-GD模块）
使用extman源码目录下docs目录中的extmail.sql和init.sql建立数据库：
#cd docs/
#mysql -u root -p
#mysql -u root -p
mysql>grant all privileges on extmai.* TO extmail@localhost IDENTIFIED BY 'extmail';
#vi /usr/local/apache/conf/httpd.conf
Include conf/extra/httpd-vhosts.conf //去掉之前注释
#cd /usr/local/apache/conf/extra/
#vi httpd-vhosts.conf（内容修改如下）
NameVirtualHost *:80
DocumentRoot "/usr/local/apache/htdocs/extmail/html/"
ServerName mail.lixin.org
ScriptAlias /extmail/cgi/ /usr/local/apache/htdocs/extmail/cgi/
Alias /extmail/ /usr/local/apache/htdocs/extmail/html/
ScriptAlias /extman/cgi/ /usr/local/apache/htdocs/extman/cgi/
Alias /extman/ /usr/local/apache/htdocs/extman/html/
Options FollowSymLinks
Allowoverride none
Order allow,deny
Allow from all
#service httpd stop
#service httpd start
安装Unix-Syslog（前提系统已经安装了perl）
#tar zxvf Unix-Syslog-0.100.tar.gz
#cd Unix-Syslog-0.100
#perl Makefile.PL
#make
#make install
安装DBD-Mysql
#tar zxvf DBD-mysql-4.012.tar.gz
#cd DBD-mysql-4.012
#perl Makefile.PL --libs="-L/usr/local/mysql/lib/mysql -lmysqlclient -L/usr/lib -lz " --cflags=-I/usr/local/mysql/include/mysql --mysql_config=/usr/local/mysql/bin/mysql_config
#make
#make install
在浏览器中输入以下连接进行访问：mail.lixin.org
进入邮件服务器,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*.
配置Mailgraph_ext
注意:安装以下软件之前,请确保你的系统已经安装了tcl、tcl-devel、libart和libart-devel的相关的软件包.
需要安装3个包:Time::HiRes、File::Tail和rrdtool，其中前2个包可以去http://
Search.cpan.org,后一个包在
安装 Time::HiRes
#tar zxvf Time-Hires-1.9707.tar.gz
#cd Time-Hires-1.9707
#perl Makefile.PL
#make
#make tetst
#make install
安装 File::Tail
#tar zxvf File-Tail-0.99.3.tar.gz
#cd File-Tail-0.99.3
#perl Makefile.PL
#make
#make install
安装rrdtiil-1.2.23
#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 -sv /usr/local/rrdtool/lib/perl/5.8.5/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/5.8.5/RRDp.pm /usr/lib/perl5/5.8.5/
#ln –sv /usr/local/rrdtool/lib/perl/5.8.5/i386-linux-thread-multi/RRDs.pm
/usr/lib/perl5/5.8.5/
复制mailgraph_ext到/usr/local,并启动之
#cp -r /usr/local/apache/htdocs/extman/addon/mailgraph_ext /usr/local
#/usr/local/mailgraph_ext/mailgraph-init start
#/usr/local/mailgraph_ext/qmonitor-init start
添加到自动启动行列
#echo “/usr/local/mailgraph_ext/mailgraph-init start”>>/etc/rc.local
#echo “/usr/local/mailgraph_ext/qmonitor-init start”>>/etc/rc.local
