在現實生活中,咱們根本不可能爲郵件用戶在郵件服務器上添加系統帳號。互聯網上成千上萬的人天天都在進行郵件傳輸和郵箱申請。php
正是採用了利用虛擬帳號映射成咱們郵件系統的系統帳號。現實生活中的126 、QQ、sina等郵箱正是使用這種技術來實現郵件的傳輸。html
Extmail可以提供例如126郵箱等webmail的全部功能,還可以在其基礎上進行二次開發,下面咱們就經過實際的操做配置來切實的體驗一下吧mysql
用戶能夠經過Extmail提供的Webmail來註冊虛擬用戶的賬號和密碼,用戶的賬號和密碼都保存在mysql數據庫中,當用戶使用虛擬的賬號和密碼經過postfix發送郵件時要經過mysql對其賬號和密碼進行認證(須要配置postfix基於mysql的認證),只有認證成功虛擬用戶才能夠發送郵件,當郵件服務器接收到一個本地用戶的郵件的時候,這個用戶的賬號和密碼也必須經過mysql的認證,不然將不能經過dovecot來接受郵件web
郵件服務器IP地址:192.168.145.100sql
DNS服務器IP地址:192.168.145.100數據庫
Apache服務器:192.168.145.100apache
Mysql數據庫:192.168.145.100vim
主機名:mail.zz.com服務器
郵件帳號:使用虛擬用戶。網絡
POP3/IMAP服務器軟件:Dovecot
Webmail平臺軟件:Extmail、Extman
APACHE、MYSQL平臺:apache mysql
SMTP服務器軟件:編譯安裝的postfix
認證功能實現軟件:編譯安裝的courier-authlib
依賴關係的解決:extmail將會用到perl的Unix::syslogd功能
下面進行環境的搭建:
[root@localhost ~]# vim /etc/resolv.conf
nameserver 192.168.145.100 //dns服務器指向
search localdomain
[root@localhost ~]# vim /etc/sysconfig/network
NETWORKING=yes
NETWORKING_IPV6=yes
HOSTNAME=mail.zz.com //主機名
[root@localhost ~]# vim /etc/hosts
127.0.0.1 localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6
[root@localhost ~]# hostname mail.zz.com
從新登陸使修改生效
因爲所安裝的軟件依賴性較多。本次採用一次性安裝
[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
15 listen-on port 53 { any; };
27 allow-query { any; };
28 allow-query-cache { any; };
37 match-clients { any; };
38 match-destinations { any; };
[root@mail etc]# vim named.rfc1912.zones 添加以下
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

啓動mysql數據庫,並給mysql的root用戶設置密碼:
[root@mail ~]# service mysqld start
[root@mail ~]# chkconfig mysqld on
在MYSQL中輸入如下指令
---------------------------------受權本地用戶
SET PASSWORD FOR root@'localhost'=PASSWORD('redhat');
SET PASSWORD FOR root@'127.0.0.1'=PASSWORD('redhat');
FLUSH PRIVILEGES;
-------------------------------受權遠程用戶
GRANT ALL PRIVILEGES ON *.* TO root@'%' IDENTIFIED BY 'redhat';
FLUSH PRIVILEGES;
也能夠經過如下命令修改:
[root@mail ~]# mysqladmin -u root password 'redhat'
啓動saslauthd服務,並將其加入到自動啓動隊列:
[root@mail ~]# service saslauthd start
[root@mail ~]# chkconfig saslauthd on
準備好須要用到的軟件包

把postfix改變成服務
[root@mail postfix-2.8.2]# mkdir /tmp/qq
[root@mail postfix-2.8.2]# cd /tmp/qq
[root@mail qq]# cp /mnt/cdrom/Server/postfix-2.3.3-2.1.el5_2.i386.rpm ./

[root@mail etc]# cd rc.d/
[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
進行一些基本配置,測試啓動postfix並進行發信
[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
說明:
myorigin參數用來指明發件人所在的域名;
mydestination參數指定postfix接收郵件時收件人的域名,即您的postfix系統要接收到哪一個域名的郵件;
myhostname 參數指定運行postfix郵件系統的主機的主機名,默認狀況下,其值被設定爲本地機器名;
mydomain參數指定您的域名,默認狀況下,postfix將myhostname的第一部分刪除而做爲mydomain的值;
mynetworks 參數指定你所在的網絡的網絡地址,postfix系統根據其值來區別用戶是遠程的仍是本地的,若是是本地網絡用戶則容許其訪問;
inet_interfaces 參數指定postfix系統監聽的網絡接口;

編輯/etc/authmysqlrc 爲如下內容,其中2000,2000 爲postfix 用戶的UID和GID。
26 MYSQL_SERVER localhost
27 MYSQL_USERNAME extmail (這時爲後文要用的數據庫的全部者的用戶名)
28 MYSQL_PASSWORD extmail (密碼)

[root@mail courier-authlib-0.63.1.20111230]# ldconfig -v
新建虛擬用戶郵箱所在的目錄,並將其權限賦予postfix用戶:
[root@mail courier-authlib-0.63.1.20111230]# cd
[root@mail ~]# mkdir -pv /var/mailbox
[root@mail ~]# chown -R postfix /var/mailbox
接下來從新配置SMTP 認證,編輯 /usr/local/lib/sasl2/smtpd.conf ,確保其爲如下內容:
[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
讓postfix支持虛擬域和虛擬用戶

說明:啓用虛擬域之後,須要取消中心域,即註釋掉myhostname, mydestination, mydomain, myorigin幾個指令;固然,你也能夠把mydestionation的值改成你本身須要的。
[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

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 ~]# vim /var/www/extsuite/extmail/webmail.cf
部分修改選項的說明:
SYS_MESSAGE_SIZE_LIMIT = 5242880
用戶能夠發送的最大郵件
SYS_USER_LANG = en_US
語言選項,可改做:
SYS_USER_LANG = zh_CN
SYS_MAILDIR_BASE = /home/domains
此處即爲您在前文所設置的用戶郵件的存放目錄,可改做:
SYS_MAILDIR_BASE = /var/mailbox
SYS_MYSQL_USER = db_user
SYS_MYSQL_PASS = db_pass
以上兩句句用來設置鏈接數據庫服務器所使用用戶名、密碼和郵件服務器用到的數據庫,這裏修改成:
SYS_MYSQL_USER = extmail
SYS_MYSQL_PASS = extmail
SYS_MYSQL_HOST = localhost
指明數據庫服務器主機名,這裏默認便可
SYS_MYSQL_TABLE = mailbox
SYS_MYSQL_ATTR_USERNAME = username
SYS_MYSQL_ATTR_DOMAIN = domain
SYS_MYSQL_ATTR_PASSWD = password
以上用來指定驗正用戶登陸裏所用到的表,以及用戶名、域名和用戶密碼分別對應的表中列的名稱;這裏默認便可
SYS_AUTHLIB_SOCKET = /var/spool/authdaemon/socket
此句用來指明authdaemo socket文件的位置,這裏修改成:
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相關配置
[root@mail ~]# service httpd start
[root@mail ~]# chkconfig httpd on
因爲extmail要進行本地郵件的投遞操做,故必須將運行apache服務器用戶的身份修改成您的郵件投遞代理的用戶;
沒有打開apache服務器的suexec功能可以下設置:
[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>
若是打開了apache服務器的suexec功能,使用如下方法來實現虛擬主機運行身份的指定。此例中的MDA爲postfix自帶,所以將指定爲postfix用戶:
<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>
而後修改 cgi執行文件屬主爲apache運行身份用戶:
[root@mail ~]# chown -R postfix.postfix /var/www/extsuite/extmail/cgi/
安裝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 //爲了方便。改成無驗證碼。
SYS_MAILDIR_BASE = /home/domains
此處即爲您在前文所設置的用戶郵件的存放目錄,可改做:
SYS_MAILDIR_BASE = /var/mailbox
修改
SYS_CAPTCHA_ON = 1
爲
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>
若是打開了apache服務器的suexec功能,咱們應該修改上面extmail的選項加入這兩句話
還應修改
[root@mail ~]# chown -R postfix.postfix /var/www/extsuite/extman/cgi/
extman運行還須要臨時目錄
建立其運行時所需的臨時目錄,並修改其相應的權限:
[root@mail ~]# mkdir -pv /tmp/extman
[root@mail ~]# chown postfix.postfix /tmp/extman
若是但願能夠顯示校驗碼,安裝perl-GD模塊會解決這個問題。若是想簡單,您能夠到如下地址下載適合您的平臺的rpm包,安裝便可: http://dries.ulyssis.org/rpm/packages/perl-GD/info.html
extman-1.1自帶了圖形化顯示日誌的功能;此功能須要rrdtool的支持,您須要安裝此些模塊纔可能正常顯示圖形日誌。
此處這些就不作了。
依賴關係的解決
extmail將會用到perl的Unix::syslogd功能,您能夠去http://search.cpan.org搜索下載原碼包進行安裝。
[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
啓動apache服務
[root@mail ~]# service httpd restart
這樣咱們的基於虛擬帳號的電子郵件系統就搭建好了
在客戶端輸入:http://192.168.145.100
選擇管理便可登入extman進行後臺管理了。默認管理賬號爲:root@extmail.org 密碼爲:extmail*123*
咱們進去後選擇添加管理員就好了,這裏添加的是帳戶名:test 密碼:123
咱們能夠選擇添加域,這裏添加的是bj.zz.com與sh.zzcom
進入到添加的域。點擊容許自由註冊。
咱們就能夠進行註冊了
註冊帳戶user2@bj.zz.com 與 user3@sh.zz.com
密碼均設爲123 ,註冊用戶的時候先選擇域。
進行郵件發送傳輸測試
user2登陸向user3發送郵件
查看郵件服務器的日誌
[root@mail ~]# tail -f /var/log/maillog
