Postfix-2.11+Dovecot-2.0.9+MySQL+Nginx+Cyrus-sasl+Extmail-1.2实现基于虚拟用户的邮件系统架构。

系统：

CentOS 7.1

IP:192.168.2.220

域名：mail.test.com

----------------------------------------------------------------------------------------

——安装前的准备工作

1)关闭Selinux

12 [root@node1 ~]# vi /etc/selinux/config

SELINUX=disabled

2)安装程序依赖包

[root@node1 ~]# yum install db4-devel ntpdate cyrus-sasl-md5 perl-GD perl-DBD-MySQL perl-GD perl-CPAN perl-CGI perl-CGI-Session cyrus-sasl-lib cyrus-sasl-plain cyrus-sasl cyrus-sasl-devel libtool-ltdl-devel telnet mail -y

3) 由于CentOS7默认安装的是MariaDB，所以要添加MySQL的yum源，有些编译需要的devel包只有epel有，所以我们把epel源也一并添加

yum install -y wget

wget http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm

rpm -ivh mysql-community-release-el7-5.noarch.rpm

wget http://dl.Fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

rpm -ivh epel-release-latest-7.noarch.rpm

4)安装Unix-Syslog补丁

[root@node1 soft]# wget http://www.cpan.org/authors/id/M/MH/MHARNISCH/Unix-Syslog-1.1.tar.gz

[root@node1 soft]# tar fzvx Unix-Syslog-1.1.tar.gz

[root@node1 soft]# cd Unix-Syslog-1.1

[root@node1 Unix-Syslog-1.1]# perl Makefile.PL

[root@node1 Unix-Syslog-1.1]# make && make install

注意：不安装此补丁的话使用extmail会报如下错误：

Unix::Syslog not found, please install it first! (in cleanup) Undefined subroutine &Ext::Logger::do_closelog called at /var/www/extsuite/extmail/libs/Ext/Logger.pm line 86.

----------------------------------------------------------------------------------------

——安装postfix

1)卸载系统自带的postfix软件和用户组

[root@node1 ~]# yum remove postfix -y

[root@node1 ~]# userdel postfix

[root@node1 ~]# groupdel postdrop

2)添加postfix用户和组

[root@node1 ~]# groupadd -g 2525 postfix

[root@node1 ~]# useradd -g postfix -u 2525 -s /sbin/nologin -M postfix

[root@node1 ~]# groupadd -g 2526 postdrop

[root@node1 ~]# useradd -g postdrop -u 2526 -s /sbin/nologin -M postdrop

3)下载postfix

[root@node1 ~]# mkdir /tmp/soft

[root@node1 ~]# cd /tmp/soft

[root@node1 soft]# wget

[root@node1 soft]# tar xfv postfix-2.11.0.tar.gz

[root@node1 soft]# cd postfix-2.11.0

[root@node1 postfix-2.11.0]# make makefiles \

'CCARGS=-DHAS_MYSQL -I/usr/include/mysql -DUSE_SASL_AUTH \

-DUSE_CYRUS_SASL -I/usr/include/sasl -DUSE_TLS ' \

'AUXLIBS=-L/usr/lib64/mysql -lmysqlclient -lz -lrt -lm -L/usr/lib64/sasl2 -lsasl2  -lssl -lcrypto'

[root@node1 postfix-2.11.0]# make && make install

4)配置相应权限

[root@node1 postfix-2.11.0]# chown -R postfix:postdrop /var/spool/postfix

[root@node1 postfix-2.11.0]# chown -R postfix:postdrop /var/lib/postfix/

[root@node1 postfix-2.11.0]# chown root /var/spool/postfix

[root@node1 postfix-2.11.0]# chown -R root /var/spool/postfix/pid

5)配置postfix

[root@node1 postfix-2.12-20140406]# vi /etc/postfix/main.cf

#设置主机名

myhostname = mail.test.com

#指定域名

mydomain = test.com

#指明发件人所在的域名

myorigin = $mydomain

#指定postfix系统监听的网络接口

inet_interfaces = all

#指定postfix接收邮件时收件人的域名 [使用虚拟域需要禁用]

mydestination = $myhostname, localhost.$mydomain, localhost,$mydomain

#指定信任网段类型

mynetworks_style = host

#指定信任的客户端

mynetworks = 192.168.0.0/16, 127.0.0.0/8

#指定允许中转邮件的域名

relay_domains = $mydestination

#设置邮件的别名

alias_maps = hash:/etc/aliases

6)设置开启启动

[root@node1 postfix-2.12-20140406]# chkconfig --add postfix

[root@node1 postfix-2.12-20140406]# chkconfig postfix on

[root@node1 postfix-2.12-20140406]# service postfix restart

virtual_alias_maps = mysql:/etc/postfix/mysql_virtual_alias_maps.cf

virtual_uid_maps = static:2525

virtual_gid_maps = static:2525

virtual_transport = virtual

——安装Extmail

1)创建相关目录并解压extmail

[root@node1 soft]# mkdir -p /var/www/extsuite

[root@node1 soft]# tar fzvx extmail-1.2.tar.gz -C /var/www/extsuite/

[root@node1 soft]# cp /var/www/extsuite/extmail-1.2 /var/www/extsuite/extmail

[root@node1 soft]# cd /var/www/extsuite/extmail

2)修改Extmail的主配置文件

[root@node1 extmail]# cp webmail.cf.default webmail.cf

[root@node1 extmail]# vi webmail.cf

SYS_SESS_DIR = /tmp/extmail

SYS_UPLOAD_TMPDIR = /tmp/extmail/upload

SYS_USER_LANG = zh_CN

SYS_MIN_PASS_LEN = 8

SYS_MAILDIR_BASE = /var/mailbox

SYS_MYSQL_USER = extmail

SYS_MYSQL_PASS = extmail

SYS_MYSQL_DB = extmail

SYS_MYSQL_HOST = localhost

SYS_MYSQL_SOCKET = /var/lib/mysql/mysql.sock

SYS_MYSQL_TABLE = mailbox

SYS_MYSQL_ATTR_USERNAME = username

SYS_MYSQL_ATTR_DOMAIN = domain

SYS_MYSQL_ATTR_PASSWD = password

SYS_AUTHLIB_SOCKET = /usr/local/courier-authlib/var/spool/authdaemon/socket

3)建立extmail的临时文件目录及session目录

[root@node1 extman]# mkdir -p /tmp/extmail/upload

[root@node1 extman]# chown postfix.postfix -R /tmp/extmail/

——安装Extman

1)解压extmail

[root@node1 soft]# tar fzvx extman-1.1.tar.gz -C /var/www/extsuite/

[root@node1 soft]# cd /var/www/extsuite/extmail

[root@node1 extsuite]# mv extman-1.1 extman

[root@node1 extsuite]# cd extman

2)修改Extman的主配置文件

[root@node1 extman]# cp webman.cf.default webman.cf

[root@node1 extman]# vi webman.cf

SYS_MAILDIR_BASE = /var/mailbox

SYS_DEFAULT_UID = 2525

SYS_DEFAULT_GID = 2525

SYS_MYSQL_USER = extmail

SYS_MYSQL_PASS = extmail

SYS_MYSQL_DB = extmail

SYS_MYSQL_HOST = localhost

SYS_MYSQL_SOCKET = /var/lib/mysql/mysql.sock

3)修改cgi目录的属主

[root@node1 extman]# chown -R postfix.postfix /var/www/extsuite/extman/cgi/

[root@node1 extman]# chown -R postfix.postfix /var/www/extsuite/extmail/cgi/

4)导入Extman的数据库

[root@node1 extman]# cd docs/

[root@node1 docs]# vi extmail.sql

将文件里面所有的TYPE=MyISAM改为ENGINE=MyISAM、命令如下：

:% s/TYPE/ENGINE/g  共有5处

[root@node1  docs]# sed -i 's/extmail.org/test.com/g' init.sql

[root@node1  docs]# sed -i 's/1000/2525/g' init.sql

[root@node1 docs]# mysql -u root < extmail.sql

[root@node1 docs]# mysql -u root < init.sql

5)授予用户extmail访问extmail数据库的权限

[root@node1 ~]# mysql -uroot -p

Enter password:

Bye

6)为Extman创建临时目录并给予权限

[root@node1 docs]# mkdir /tmp/extman

[root@node1 docs]# chown postfix.postfix -R /tmp/extman/

——重启postfix、dovecot、saslauthd、nginx

[root@node1 docs]# service postfix restart

[root@node1 docs]# service dovecot restart

[root@node1 docs]# service saslauthd restart

——测试虚拟用户实现结果

1)测试Postfix 支持虚拟用户

[root@node1 docs]# /usr/local/courier-authlib/sbin/authtest -s login postmaster@test.com extmail

Authentication succeeded.        //  表示成功

Authenticated: postmaster@test.com  (uid 2525, gid 2525)

Home Directory: /mailbox/test.com/postmaster

Maildir: /mailbox/test.com/postmaster/Maildir/

Quota: (none)

Encrypted Password: $1$phz1mRrj$3ok6BjeaoJYWDBsEPZb5C0

Cleartext Password: extmail

Options: (none)

2)测试虚拟用户SMPT发信认证

[root@node1 docs]# printf  "postmaster@test.com" | openssl base64

cG9zdG1hc3RlckBleHRtYWlsLm9yZw==

[root@node1 docs]# printf  "extmail" | openssl base64

ZXh0bWFpbA==

[root@node1 docs]#

[root@node1 docs]# telnet localhost 25

ZXh0bWFpbA==

235 2.0.0 Authentication successful      //  表示成功

quit

221 2.0.0 Bye

Connection closed by foreign host.

——启动extmail和extman的相关程序

1)修改dispatch-initSU_UID和SU_GID

[root@node1 docs]# vi /var/www/extsuite/extmail/dispatch-init

SU_UID=postfix

SU_GID=postfix

2)启动dispatch-init并添加到/etc/rc.local [不启动dispatch-init]

[root@node1 docs]# /var/www/extsuite/extmail/dispatch-init start

[root@node1 docs]# echo "/var/www/extsuite/extmail/dispatch-init start" >> /etc/rc.local

注意：不启动dispatch-init 连接extmail时候会报502错误。

3)启动cmdserver并添加到/etc/rc.local

[root@node1 docs]# /data/www/extman/daemon/cmdserver -v -d

[root@node1 docs]# echo "/var/www/extsuite/extman/daemon/cmdserver -v -d " >> /etc/rc.local

注意：不启动cmdserver的话，extmail登录管理后台，系统信息里会报Connection refused错误

如果出现如下错误：Undefined subroutine &Ext::Utils::sort2name called at /var/www/extsuite/extmail/libs/Ext/App/Folders.pm line 387.

解决办法：

[root@node1 Ext]# cd /var/www/extsuite/extmail/libs/Ext

[root@node1 Ext]# cp Utils.pm /var/www/extsuite/extman/libs/

[root@node1 Ext]# cd /var/www/extsuite/extman/libs/Ext

[root@node1 Ext]# mv Utils.pm ManUtils.pm

[root@node1 Ext]# /var/www/extsuite/extmail/dispatch-init stop

[root@node1 Ext]# /var/www/extsuite/extmail/dispatch-init start

——Extmail虚拟主机配置 [这里用的是nginx]

1)配置extmail虚拟主机

[root@node1 ~]# vi /usr/local/nginx/conf/conf.d/extmail.conf

server {

listen      8080;

server_name  mail.test.com;

index index.html index.htm index.php index.cgi;

root  /var/www/extsuite/extmail/html/;

location /extmail/cgi/ {

fastcgi_pass          127.0.0.1:8888;

fastcgi_index        index.cgi;

fastcgi_param  SCRIPT_FILENAME  /var/www/extsuite/extmail/cgi/$fastcgi_script_name;

include              fcgi.conf;

}

location  /extmail/  {

alias  /var/www/extsuite/extmail/html/;

}

location /extman/cgi/ {

fastcgi_pass          127.0.0.1:8888;

fastcgi_index        index.cgi;

fastcgi_param  SCRIPT_FILENAME  /var/www/extsuite/extman/cgi/$fastcgi_script_name;

include            fcgi.conf;

}

location /extman/ {

alias  /var/www/extsuite/extman/html/;

}

access_log  /usr/local/nginx/logs/extmail_access.log;

}

2)创建fcgi.conf

12345678910111213141516 [root@node1 ~]# vi /usr/local/nginx/conf/fcgi.conf

fastcgi_param  GATEWAY_INTERFACE  CGI/1.1;

fastcgi_param  SERVER_SOFTWARE    nginx;

fastcgi_param  QUERY_STRING      $query_string;

fastcgi_param  REQUEST_METHOD    $request_method;

fastcgi_param  CONTENT_TYPE      $content_type;

fastcgi_param  CONTENT_LENGTH    $content_length;

fastcgi_param  SCRIPT_NAME        $fastcgi_script_name;

fastcgi_param  REQUEST_URI        $request_uri;

fastcgi_param  DOCUMENT_ROOT      $document_root;

fastcgi_param  SERVER_PROTOCOL    $server_protocol;

fastcgi_param  REMOTE_ADDR        $remote_addr;

fastcgi_param  REMOTE_PORT        $remote_port;

fastcgi_param  SERVER_ADDR        $server_addr;

fastcgi_param  SERVER_PORT        $server_port;

fastcgi_param  SERVER_NAME        $server_name;

3)重启nginx

[root@node1 ~]# service nginx restart

——Extmail测试

http://192.168.2.220:8080/extman/  管理后台  用户名：root@test.com  初始密码：extmail*123*

http://192.168.2.220:8080/extmail/cgi/index.cgi extmail用户登录界面

注册账号后登陆报错：

Can't chdir to /var/mailbox/test.com/fei.xiao/Maildir/, No such file or directory

解决方案：

目录权限属性问题：

查看extman的:

SYS_MAILDIR_BASE = /var/mailbox

配置是否正确,删除域名再重建，在新建用户的时候会自动在/var/mailbox/下创建该用户的域名和邮件目录
