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 7.1IP:192.168.2.220域名：mail.test.com----------------------------------------------------------------------------------------——安装前的准备工作1）关闭Selinux1
2
# vi /etc/selinux/config
SELINUX=disabled
2）安装程序依赖包
1
# 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
1

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

# wget http://www.cpan.org/authors/id/M/MH/MHARNISCH/Unix-Syslog-1.1.tar.gz
# tar fzvx Unix-Syslog-1.1.tar.gz
# cd Unix-Syslog-1.1
# perl Makefile.PL
# 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
1
2
3
# yum remove postfix -y
# userdel postfix
# groupdel postdrop
2）添加postfix用户和组

# groupadd -g 2526 postdrop
# useradd -g postdrop -u 2526 -s /sbin/nologin -M postdrop
3）下载postfix

'AUXLIBS=-L/usr/lib64/mysql -lmysqlclient -lz -lrt -lm -L/usr/lib64/sasl2 -lsasl2 -lssl -lcrypto'
# make && make install
4）配置相应权限

# chown -R postfix:postdrop /var/spool/postfix
# chown -R postfix:postdrop /var/lib/postfix/
# chown root /var/spool/postfix

6）为Extman创建临时目录并给予权限

# mkdir /tmp/extman
# chown postfix.postfix -R /tmp/extman/
——重启postfix、dovecot、saslauthd、nginx
1

3
# service postfix restart
# service dovecot restart
# service saslauthd restart
——测试虚拟用户实现结果
1）测试Postfix 支持虚拟用户
# /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

——启动extmail和extman的相关程序
1）修改dispatch-initSU_UID和SU_GID
1
2
3
# 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]
1
2
# /var/www/extsuite/extmail/dispatch-init start
# 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
1
2
# /data/www/extman/daemon/cmdserver -v -d
# 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：
1

# cd /var/www/extsuite/extmail/libs/Ext
# cp Utils.pm /var/www/extsuite/extman/libs/
# cd /var/www/extsuite/extman/libs/Ext
# mv Utils.pm ManUtils.pm
# /var/www/extsuite/extmail/dispatch-init stop
# /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
# vi /usr/local/nginx/conf/conf.d/extmail.conf
server {
listen 8080;
server_namemail.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_paramSCRIPT_FILENAME /var/www/extsuite/extmail/cgi/$fastcgi_script_name;
include fcgi.conf;
}
location/extmail/{
alias/var/www/extsuite/extmail/html/;
}
location /extman/cgi/ {
fastcgi_pass 127.0.0.1:8888;
fastcgi_index index.cgi;
fastcgi_paramSCRIPT_FILENAME /var/www/extsuite/extman/cgi/$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

fastcgi_paramREMOTE_PORT $remote_port;
fastcgi_paramSERVER_ADDR $server_addr;
fastcgi_paramSERVER_PORT $server_port;
fastcgi_paramSERVER_NAME $server_name;
3）重启nginx

# 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：
1
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
好资源，必须支持楼主。
