postfix和extmail配置

west open source  technology center

chdir to /home/domains/test.com/test/Maildir/, Permissiondenied(如果遇到这样的问题，就是selinux没有关闭，关闭selinux或者安下面的更改)。

铃高手 hzqbbc 呀，
一语惊醒我了。
的确忘了修改  /etc/rc.d/rc.local
加入了后再次重启都没有问题了。

/usr/sbin/setsebool httpd_disable_trans=1
/usr/sbin/setsebool mysqld_disable_trans=1
/etc/init.d/mysqld restart
/etc/init.d/httpd restart

1.安装postfix解

      Yuminstall postfix �Cy

      /etc/init.d/postfixstart

      Netstat�Cantlpe | grep 25

这样就可以给自己的主机发邮件了

Mailq 查看没有发出去的邮件队列

2 配置postfix的主配置文件

Vi /etc/postfix/main.cf更改如下：

myhostname   =server90.example.com(主机名)

mydomain = example.com (主机域名)

inet_interfaces = all 监听的网络接口

inet_protocols = all 监听ipv4和ipv6

mydestination = $myhostname,( localhost.去掉)$mydomain,localhost

/etc/init.d/postfix restart 就可以发邮件了

3 配置虚拟用户

Postconf �Cd 列出所有虚拟配置

Postconf �Ce “virtual_alias_maps =hash:/etc/postfix/virtual”(hash哈希加密virtual 为虚拟用户所在文件)

Vi /etc/postfix/virtual 在最后一行增加

[email protected]（真是的地址）[email protected](虚拟的地址)

postmap virtual 生成virtual.db文件。让postfix可读加密文件

/etc/init.d/postfix  restart

postconf �Cd | grep generic

postconf �Ce “smtp_generic_manps” =hash:/etc/postfix/generic”

vi /etc/postconf/generic 在最后增加

[email protected](真实邮址)        [email protected]（假装的邮址）

postmap generic

/etc/init.d/postfix  restart

3 用telnet 检验postfix是否可以发信

telnet 192.168.0.250 25

ehlo hello

mail from:[email protected]

rcpt to:[email protected]

data

as

as

quit

4 设置拒绝哪些用户和域可以收邮件

Postconf �Cd | grep client

Postconf �Ce “smtpd_client_restrictions =check_client_access hash:/etc/postfix/access”

Vi access最后增加一行

192.168.0.254 REJECT(拒绝这个域)

Postmap access （生成access.db文件）

/etc/init.d/postfix restart

5 拒绝哪些用户可以发邮件

Postconf �Cd | grep sender

Postconf �Ce “smtpd_sender_restrictions =check_sender_access hash:?etc/postfix/sender”

Vi /etc/postfix/sender更改如下：

[email protected]          REJECT

postmap sender

/etc/init.d/postfix restart

6 设置哪些用户不可以收

Postconf �Cd |grep reci

Postconf �Ce “smtpd_recipient_restrictions =check_recipient_accesshash:/etc/postfix/recipient,permit_mynetworks,reject_unauth_destination”

Vi recipient 更改如下：

[email protected]          REJECT

postmap recipient

/etc/init.d/postfix restart

7 设置收信

Yum install dovecot �Cy (安装豆腐块)

/etc/init.d/dovecot start

Chkconfig dovecot on

Netstat �Cantlpe | grep dovecot

Cd /etc/dovecot

Cd conf.d/

Vi dovecot.conf 打开加密验证就可以收信了

8 postfix和mysql一起用

Yum install mysql-server �Cy

/etc/init.d/mysqld start

装完可以直接用mysql 登录的

Show databases;(查看数据库)

Use mysql(切换数据库)

Show tables;(查看数据库中的表)

Select * from user ;查看数据表中的信息

Mysql_secure_installation 更改数据库的root的密码

Create database westos;创建数据库

Use westos;

Create table linux (username varchar(50)not null,password varchar(50) not null );

Desc linux;查看表结构

Insert into linux values (‘user1’,’passwd1’);给表中插入值

Select * from linux 查看表中数据

Update linux set password=password(‘paswd1’)where usernme=’user1’;

Delete from linux where username=’user2’;

Delete linux 删除所有表中的信息

Drop table linux;删除表

Drop database westos; 删除数据库

Grant all on westos.* to user1@localhostidentified by ‘lee’

忘记mysql的root密码

1 停止mysql 服务

/etc/init.d/mysqld stop

Mysqld_safe �Cskip-grant-tables&后台执行此命令

Mysql 直接进入mysql

Use mysql；

Show tables;

Update user set passeord(‘lee’) where user=’root’;

/etc/init.d/mysqld restart

Mysql �Curoot �Cplee就能进了

Mysqladmin �Curoot �Cplee password westos 改root的密码

安装phpMyAdmin

下载安装包

Tar jxf phpMyAdmin-….解压

Mv phpmyadmin-… phpadmin

安装支持php用行的软件

Yum install php httpd php-mysql �Cy

/etc/init.d/httpd start

Mv phpadmin /var/www/html

Cd /var/www/html/phpadmin

Cp �Cp config.sample.inc.php config.inc.php

Vi config.inc.php 更改如下

给 YOUＭＵＳＴFILEＩＮTHIＦＯＲCOOKIEＡＵＴＨ!*/ 前面的等号后面=’westos’加给westos 为密码

/etc/init.d/httpd restart

在浏览器输入192.168.0.250/phpadmin就可以用图形化工具管理数据库了

3 配置mysql和postfix可以使postfix使用mysql中的数据

1 删除postfix以前所有的配置最好的办法是 yum reinstall postfix �Cy

Cd /etc/postfix

在mysql 中建立一个postfix数据库建立一个mail表表中有4个字段 usernamepassword domain maildir 四个值分别为[email protected] user1westos.org westos.org/user1/maildir/(最后必须有反斜杠)

2 添加用户 useradd �Cg 800 vmail

Postconf �Cd

Postconf �Ce “virtual_mailbox_base =/home/vmail”

Postconf �Ce “virtual_uid_maps =  static:800”

Postconf �Ce “virtual_uid_maps = static:800”

3给mysql建一个有权限的用户进入mysql

Use mysql

Grant all on postfix.all to postfix@’%’identified by ‘postfix’;

Postconf �Ce “virtual_alias_maps =mysql:/etc/postfix/mysql-alias.cf” 查找用户的

Postconf �Ce “virtual_mailbox_domain =mysql:/etc/postfix/mysql-domain.cf”查找域名的

Postconf �Ce “virtual_mailbox_maps =mysql:/etc//postfix/mysql-mailbox”查找邮件地址的

Cd /etc/postfix

Vi mysql-alias.cf 编写如下：

hosts = localhost

user = postfix(数据库中添加的用户)

password = postfix

dbname = postfix数据库名字

table = mail 表的名字

select_field = username

where_field = uername

vi mysql-domain 编写如下：

hosts = localhost

user = postfix

password = postfix

dbname = postfix

table = mail

select_field = domain

where_field = domain

vi mysql-mailbox.cf 编写如下：

hosts = localhost

user = postfix

password = postfix

dbname = postfix

table = mail

select_file = maildir

where_field = username

/etc/init.d/postfix restart

检验

Postmap �Cq “[email protected]” mysql:/etc/postfix/mysql-alias.cf

Postmap �Cq “[email protected]”mysql:/etc/postfix/mysql-mailbox.cf

Postmap �Cq “westos”mysql:/etc/postfix/mysql-domain

给user1发一分邮件如果/home/mail/出现westos.org 则配置成功

Mail [email protected]

4 配置豆腐块让他可以收邮件配合mysql

Yum install dovecot dovecot-mysql

/etc/init.d/dovecot start

Cd /etc/dovecot/

Cd conf.d/

Vi 10-mail.conf更改如下：

Mail_location =maildir:/home/vmail/%d/%n/maildir

First_valid_uid = 800

Vi 10-auth.conf更改如下：

Auth_mechanisms = plain

去掉!includeauth-sql.conf.xt 打开sql验证

Cd /usr./share/doc/dovecot-2.0/example-config/

Cp dovecot-sql.conf.ext /etc/dovecot/

Cd /etc/dovecot/

Vim dovecot-sql.conf.ext更改如下：

Driver = mysql

Connect = host=localhost dbname=postfixuser=postfix password=postfix

Default_pass_scheme = plain

Password_query = \

Select username,domain,password \

From mail where username = ‘%u’ and domain= ‘%d’

/etc/init.d /dovecotrestart

验证

telnet 192.168.0.250 110

user [email protected]

pass user1

看能发过去不

5 postfix 版本升级

5.1postconf mail_version 查看当前系统postfix的版本

到postfix.org 下载最新的版本

Scp [email protected]:/var/ftp/pub/docs/postfix吧本机的postfix上传的254主机上

tar zxf postfix-2.10.2tar.gz解压最新版本

cd postfix    

dig -t mx  qq.com 查看qq.com的邮件主机 dig �Ct gmail.com

less INSTALL 查看安装说明

rpm �Cq postfix 查看postfix的版本

postconf -m 查看postconf 安装支持的服务

postconf �Cn 查看postfix的最新配置

inet_protocols=ipv4接听的ip类型

升级 postfix 必须安装make

yum  install  -y make  

cd /README_FILES/

less MYSQL_README 查看MYSQL_README 安装说明

make  �Cf  Makefile.init     makefiles

如果提示  Install the  appropriate  db*-devel package first

yum install  db*-devel  -y

如果提示 gcc :command not found

yum install  -y  gcc 安装gcc 编译器

makeupgrade  升级postfix

postconf  -m 查看支持的服务此时不支持Mysql 要让postfix支持mysql 则要升级mysql

要升级mysql则要安装mysql的编译

yum  install mysql-devel  -y

rpm -ql  mysql-devel

cd /usr/include/mysql/ 带.h的都为编译文件

cd /usr/lib64/mysql/  带.so的文件

最好的办法是吧最新的postfix删除

make -f  makefile.init   makefiles \

> ‘CCARGS=-DHAS_MYSQL  -I /usr/include/mysql’   \

> ‘AUXLIBS=-L /usr/lib64/mysql  -lmysqlclient -lz  -lm’

然后 make  upgrade 升级

Postconf -m  查看支持的服务

/etc/init.d/postfix   restart  

Netstat -antlp | grep 25 (postfix接听25端口)

yum  install  -y   mailx邮件发送

5.2 安装mysql

Mysqladmin -uroot �Cpwestos password 123

Mysqladmin �Curoot password westos

Yum install mysql-server mysql

flush privileges; 刷新数据库

mysqldump �Curoot �Cpwestos mysql > mysql.bak备份数据库

mysql �Curoot �Cpwestos westos < mysql.bak回复数据库

忘记mysql的root密码修改密码

Mysqld_safe --skip-grant-tables &后台运行

mysql  进入mysql然后更改mysql的root密码

/etc/init.d/mysqld  restart

5.3.用phpMyAdmin 管理数据库

tar jxf  phpMyAdmin….

Mv phpMyAdmin /var/www/html/  

Cd /var/www/html/phpMyAdmin

Cp config.sample.inc.php  config.inc.php

Vi config.inc.php 更改如下：

在 = ‘westos ’加好 YOUＭＵＳＴFILLＩＮ　ＴＨＩＳ　ＦＯＲ　ＣＯＯＫＩＥ　ＡＵＴＨ　就可以用phpMyAdmin管理mysql了

5.4 配置postfix使他可以使用数据库中的用户

Useradd �Cu 800 email

Postconf -d

Postconf -e virtual_mailbox_base=/home/email/

Postconf �Ce virtual_uid_maps=static:800

Postconf �Ce virtual_gid_maps=static:800

Cd /etc/popstfix/

Mysql �Cpwestos

Grant all on linux.* to email@localhostidentified by ‘westos’;user

Vi mysql:alias.cf 如下：

User = email

Password = email

Dbname = linux

Table = email

Select_field = username

Where_field = username

Vi mysql:domain.cf

User = email

Password = email

Dbname = linux

Table = email

Select_field = domain

Where_field = domain

Vi mysql:mailbox
