在现实生活中,我们根本不可能为邮件用户在邮件服务器上添加系统账号。互联网上成千上万的人每天都在进行邮件传输和邮箱申请。
正是采用了利用虚拟账号映射成我们邮件系统的系统账号。现实生活中的126 、QQ、sina等邮箱正是使用这种技术来实现邮件的传输。
Extmail能够提供例如126邮箱等webmail的所有功能,还能够在其基础上进行二次开发,下面我们就通过实际的操作配置来切实的体验一下吧
用户可以通过Extmail提供的Webmail来注册虚拟用户的帐号和密码,用户的帐号和密码都保存在mysql数据库中,当用户使用虚拟的帐号和密码通过postfix发送邮件时要通过mysql对其帐号和密码进行认证(需要配置postfix基于mysql的认证),只有认证成功虚拟用户才可以发送邮件,当邮件服务器接收到一个本地用户的邮件的时候,这个用户的帐号和密码也必须通过mysql的认证,否则将不能通过dovecot来接受邮件
邮件服务器IP地址:192.168.145.100
DNS服务器IP地址:192.168.145.100
Apache服务器:192.168.145.100
Mysql数据库:192.168.145.100
主机名:mail.zz.com
邮件账号:使用虚拟用户。
POP3/IMAP服务器软件:Dovecot
Webmail平台软件:Extmail、Extman
APACHE、MYSQL平台:apache mysql
SMTP服务器软件:编译安装的postfix
认证功能实现软件:编译安装的courier-authlib
依赖关系的解决:extmail将会用到perl的Unix::syslogd功能
下面进行环境的搭建:
[root@localhost ~]# vim /etc/resolv.conf
nameserver 192.168.145.100 //dns服务器指向
search localdomain
[root@localhost ~]# vim /etc/sysconfig/network
NETWORKING=yes
NETWORKING_IPV6=yes
HOSTNAME=mail.zz.com //主机名
[root@localhost ~]# vim /etc/hosts
127.0.0.1 localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6
[root@localhost ~]# hostname mail.zz.com
重新登录使修改生效
由于所安装的软件依赖性较多。本次采用一次性安装
[root@localhost ~]# mount /dev/cdrom /mnt/cdrom
[root@mail ~]# yum install bind bind-chroot caching-nameserver
[root@mail ~]# cd /var/named/chroot/etc/
[root@mail etc]# cp -p named.caching-nameserver.conf named.conf
[root@mail etc]# vim named.conf

27 allow-query { any; };
28 allow-query-cache { any; };
37 match-clients { any; };
38 match-destinations { any; };
[root@mail etc]# vim named.rfc1912.zones 添加如下
27 zone "zz.com" IN {
28 type master;
29 file "zz.com.zone";
30 allow-update { none; };
31 };
[root@mail etc]# cd ../var/named/
[root@mail named]# cp -p localhost.zone zz.com.zone
[root@mail named]# vim zz.com.zone
[root@mail named]# service named start
[root@mail named]# rndc reload
[root@mail named]# chkconfig named on
[root@mail named]# service sendmail stop
[root@mail named]# chkconfig sendmail off
[root@mail ~]# yum install httpd php php-mysql 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

[root@mail rc.d]# cd init.d/
[root@mail init.d]# cp postfix /etc/init.d/
[root@mail init.d]# service postfix restart
[root@mail init.d]# chkconfig postfix on
进行一些基本配置,测试启动postfix并进行发信
[root@mail init.d]# vim /etc/postfix/main.cf
75 myhostname = mail.zz.com
83 mydomain = zz.com
99 myorigin = $mydomain
113 inet_interfaces = all
161 mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain
260 mynetworks = 127.0.0.0/8
说明:
myorigin参数用来指明发件人所在的域名;
mydestination参数指定postfix接收邮件时收件人的域名,即您的postfix系统要接收到哪个域名的邮件;
myhostname 参数指定运行postfix邮件系统的主机的主机名,默认情况下,其值被设定为本地机器名;
mydomain参数指定您的域名,默认情况下,postfix将myhostname的第一部分删除而作为mydomain的值;
mynetworks 参数指定你所在的网络的网络地址,postfix系统根据其值来区别用户是远程的还是本地的,如果是本地网络用户则允许其访问;
inet_interfaces 参数指定postfix系统监听的网络接口;
[root@mail init.d]# service postfix restart

27 authmodulelist="authmysql"
34 authmodulelistorig="authmysql"
53 daemons=10
编辑/etc/authmysqlrc 为以下内容,其中2000,2000 为postfix 用户的UID和GID。
26 MYSQL_SERVER localhost
27 MYSQL_USERNAME extmail (这时为后文要用的数据库的所有者的用户名)
28 MYSQL_PASSWORD extmail (密码)
49 MYSQL_SOCKET /var/mysql/mysql.sock
56 MYSQL_PORT 3306 (指定你的mysql监听的端口,这里使用默认的3306)
68 MYSQL_DATABASE extmail
83 MYSQL_USER_TABLE mailbox
92 MYSQL_CRYPT_PWFIELD password
113 MYSQL_UID_FIELD 2000
119 MYSQL_GID_FIELD 2000
128 MYSQL_LOGIN_FIELD username
133 MYSQL_HOME_FIELD concat('/var/mailbox/',homedir)
139 MYSQL_NAME_FIELD name
150 MYSQL_MAILDIR_FIELD concat('/var/mailbox/',maildir)
[root@mail courier-authlib-0.63.1.20111230]# cp courier-authlib.sysvinit /etc/init.d/courier-authlib
[root@mail courier-authlib-0.63.1.20111230]# chmod 755 /etc/init.d/courier-authlib
[root@mail courier-authlib-0.63.1.20111230]# chkconfig --add courier-authlib
[root@mail courier-authlib-0.63.1.20111230]# chkconfig --level 2345 courier-authlib on
[root@mail courier-authlib-0.63.1.20111230]# echo "/usr/local/courier-authlib/lib/courier-authlib" >> /etc/ld.so.conf.d/courier-authlib.conf
[root@mail courier-authlib-0.63.1.20111230]# ldconfig -v
新建虚拟用户邮箱所在的目录,并将其权限赋予postfix用户:
[root@mail courier-authlib-0.63.1.20111230]# cd
[root@mail ~]# mkdir -pv /var/mailbox
[root@mail ~]# chown -R postfix /var/mailbox
接下来重新配置SMTP 认证,编辑 /usr/local/lib/sasl2/smtpd.conf ,确保其为以下内容:
[root@mail ~]# vim /usr/lib/sasl2/smtpd.conf
pwcheck_method: authdaemond
log_level: 3
mech_list:PLAIN LOGIN
authdaemond_path:/usr/local/courier-authlib/var/spool/authdaemon/socket
[root@mail ~]# service saslauthd restart
[root@mail ~]# service courier-authlib start
让postfix支持虚拟域和虚拟用户
[root@mail ~]# vim /etc/postfix/main.cf 添加如下内容

说明:启用虚拟域以后,需要取消中心域,即注释掉myhostname, mydestination, mydomain, myorigin几个指令;当然,你也可以把mydestionation的值改为你自己需要的。
[root@mail docs]# vim /etc/postfix/main.cf
75 #myhostname = mail.zz.com
83 #mydomain = zz.com
99 #myorigin = $mydomain
161 #mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain
[root@mail docs]# service postfix restart
配置dovecot
[root@mail docs]# vim /etc/dovecot.conf
211 mail_location = maildir:/var/mailbox/%d/%n/Maildir
795 #passdb pam {
828 #}
869 passdb sql {
870 # Path for SQL configuration file, see doc/dovecot-sql-example.conf
871 args = /etc/dovecot-mysql.conf
872 }
896 #userdb passwd {

930 userdb sql {
931 # Path for SQL configuration file, see doc/dovecot-sql-example.conf
932 args = /etc/dovecot-mysql.conf
933 }
postfix的配置文件也要该
[root@mail docs]# vim /etc/postfix/main.cf
415 home_mailbox = Maildir/
[root@mail docs]# vim /etc/dovecot-mysql.conf
driver = mysql
connect = host=localhost dbname=extmail user=extmail password=extmail
default_pass_scheme = CRYPT
password_query = SELECT username AS user,password AS password FROM mailbox WHERE username = '%u'
user_query = SELECT maildir, uidnumber AS uid, gidnumber AS gid FROM mailbox WHERE username = '%u'
[root@mail docs]# service postfix restart
[root@mail docs]# service dovecot start
[root@mail docs]# chkconfig dovecot on
[root@mail docs]# cd
[root@mail ~]# tar zxvf extmail-1.2.tar.gz
[root@mail ~]# mv extmail-1.2 /var/www/extsuite/extmail
[root@mail ~]# cp /var/www/extsuite/extmail/webmail.cf.default /var/www/extsuite/extmail/webmail.cf
[root@mail ~]# vim /var/www/extsuite/extmail/webmail.cf
部分修改选项的说明:
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_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
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
apache相关配置
[root@mail ~]# service httpd start
[root@mail ~]# chkconfig httpd on
由于extmail要进行本地邮件的投递操作,故必须将运行apache服务器用户的身份修改为您的邮件投递代理的用户;
没有打开apache服务器的suexec功能可如下设置:
[root@mail ~]# vim /etc/httpd/conf/httpd.conf
231 User postfix
232 Group postfix
992 <VirtualHost 192.168.145.100:80>
993 ServerName mail.zz.com
994 DocumentRoot /var/www/extsuite/extmail/html/
995 ScriptAlias /extmail/cgi /var/www/extsuite/extmail/cgi
996 Alias /extmail /var/www/extsuite/extmail/html
997 </VirtualHost>
如果打开了apache服务器的suexec功能,使用以下方法来实现虚拟主机运行身份的指定。此例中的MDA为postfix自带,因此将指定为postfix用户:
<VirtualHost *:80>
ServerName mail.test.com
DocumentRoot /var/www/extsuite/extmail/html/
ScriptAlias /extmail/cgi /var/www/extsuite/extmail/cgi
Alias /extmail /var/www/extsuite/extmail/html
SuexecUserGroup postfix postfix
< /VirtualHost>
然后修改 cgi执行文件属主为apache运行身份用户:
[root@mail ~]# chown -R postfix.postfix /var/www/extsuite/extmail/cgi/
安装Extman-1.1
[root@mail ~]# tar zxvf extman-1.1.tar.gz
[root@mail ~]# mv extman-1.1 /var/www/extsuite/extman
[root@mail ~]# cp /var/www/extsuite/extman/webman.cf.default /var/www/extsuite/extman/webman.cf
[root@mail ~]# vim /var/www/extsuite/extman/webman.cf
12 SYS_MAILDIR_BASE = /var/mailbox
21 SYS_CAPTCHA_ON = 0 //为了方便。改为无验证码。
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
修改
SYS_CAPTCHA_ON = 1
为
SYS_CAPTCHA_ON = 0
[root@mail ~]# vim /etc/httpd/conf/httpd.conf
<VirtualHost 192.168.145.100:80>
ServerName mail.zz.com
DocumentRoot /var/www/extsuite/extmail/html/
ScriptAlias /extmail/cgi /var/www/extsuite/extmail/cgi
Alias /extmail /var/www/extsuite/extmail/html
ScriptAlias /extman/cgi /var/www/extsuite/extman/cgi
Alias /extman /var/www/extsuite/extman/html
< /VirtualHost>
如果打开了apache服务器的suexec功能,我们应该修改上面extmail的选项加入这两句话
还应修改
[root@mail ~]# chown -R postfix.postfix /var/www/extsuite/extman/cgi/
extman运行还需要临时目录
创建其运行时所需的临时目录,并修改其相应的权限:
[root@mail ~]# mkdir -pv /tmp/extman
[root@mail ~]# chown postfix.postfix /tmp/extman
如果希望可以显示校验码,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平台的rpm包,安装即可: http://dries.ulyssis.org/rpm/packages/perl-GD/info.html
extman-1.1自带了图形化显示日志的功能;此功能需要rrdtool的支持,您需要安装此些模块才可能正常显示图形日志。
此处这些就不做了。
依赖关系的解决
extmail将会用到perl的Unix::syslogd功能,您可以去http://search.cpan.org搜索下载原码包进行安装。
[root@mail ~]# tar zxvf Unix-Syslog-1.1.tar.gz
[root@mail ~]# cd Unix-Syslog-1.1
[root@mail Unix-Syslog-1.1]# perl Makefile.PL
[root@mail Unix-Syslog-1.1]# make
[root@mail Unix-Syslog-1.1]# make install
启动apache服务
[root@mail ~]# service httpd restart
这样我们的基于虚拟账号的电子邮件系统就搭建好了
在客户端输入:http://192.168.145.100
选择管理即可登入extman进行后台管理了。默认管理帐号为:[email protected] 密码为:extmail*123*
