postfix+mysql+dovecot+extmail 邮件系统

安装mysql

yum install mysql-server -y

/etc/init.d/mysqld start

/usr/bin/mysql_secure_installation 安全配置

mysql -uroot -p123    登录方式

mysqladmin -u root -h desktop44.example.com password 'new-password' 远程登录mysql

mysqladmin -uroot -p123 password westos 修改密码

如果你忘记了mysql密码，你可以这么做

/etc/init.d/mysqld stop

mysqld_safe --skip-grant-tables & 跳过权限表

mysql    现在进入的模式相当于系统的单用户

update user set password='' where user='root'; 清空root密码

/etc/init.d/mysqld restart 重启服务 刚刚后台运行了 mysqld_safe

mysqladmin -uroot password 123

使用web访问msql

cd phpmyadmin

cp config.sample.inc.php config.inc.php

vi config.inc.php

$cfg['blowfish_secret'] = 'aaa'; /* YOU MUST FILL IN THIS FOR COOKIE AUTH! */

默认' ' 中间为空，随便添加些字符就可以

yum install php php-mysql -y   发布的网页是php页面

/etc/init.d/httpd restart

192.168.0.44/phpadmin

选择 中文utf8登录

mkdir /var/www/extsuite

tar zxf ~/extman-1.1.tar.gz -C .

tar zxf ~/extmail-1.2.tar.gz -C .

cd /var/www/extsuite/extman/docs

mysql -uroot -p123 < extmail.sql

修改登录密码

mysql -uroot -p123 < init.sql   修改init.sql  修改postmaster和root的登录密码

cp mysql_virtual_alias_maps.cf /etc/postfix/mysql-alias.cf

cp mysql_virtual_domains_maps.cf /etc/postfix/mysql-domains.cf

cp mysql_virtual_mailbox_maps.cf /etc/postfix/mysql-mailboxs.cf  拷贝模板到指定目录

INSTALL里面是默认httpd的配置，将虚拟主机添加到/etc/httpd/conf/httpd.conf(extmail和extman里面都有INSTALL，添加到一个虚拟主机里面就行)

vi /etc/httpd/conf/httpd.conf

DocumentRoot /var/www/html

ServerName desktop144.example.com

ServerName mail.extmail.org

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

SuexecUserGroup vmail vmail

cd /var/ww/extsuite/extmail

chown -R vmail.vmail cgi

yum install perl-CGI -y

cp web.mail.cf.default   webmail.cf

vi webmail.cf

SYS_LOG_ON = 0

SYS_MAILDIR_BASE = /home/vmail/

SYS_CRYPT_TYPE = plain

SYS_MYSQL_USER = extmail

SYS_MYSQL_PASS = extmail

SYS_MYSQL_DB = extmail

SYS_MYSQL_HOST = localhost

修改extmail里面的wenmail.cf SYS_LOG_ON = 1    如果不安装下面的文件，打开网页时就会提示缺少Unix-Syslog

tar zxf Unix-Syslog-1.1.tar.gz

cd Unix-Syslog

vi README

perl Makefile.PL

yum install perl-ExtUtils-MakeMaker -y

perl Makefile.PL

make test

yum install gcc -y

make install

cd extman                 和extmial同样

chown -R vmail.vmail cgi

cp webman.cf.default webman.cf

yum install perl-GD -y        验证码图片支持

vi webman.cf

SYS_MAILDIR_BASE = /home/vmail

SYS_SESS_DIR = /tmp/

SYS_CAPTCHA_ON = 1            验证码

SYS_CAPTCHA_LEN = 4

SYS_CRYPT_TYPE = plain        明文密码

postfix配置

useradd -u 600 -s /sbin/nologin vmail  建立一个邮件存放目录

postconf  -m 可以查看postfix支持

postconf -d 查看默认设置  -n查看当前设置监听所有的25端口

postconf -e virtual_mailbox_base=/home/vmail 设置存放位置

postconf -e virtual_uid_maps=static:600 以UID为600的用户身份执行

postconf -e virtual_gid_maps=static:600 以GID为600的用户身份执行

postconf -e virtual_alias_maps=mysql:/etc/postfix/mysql-alias.cf

postconf -e virtual_mailbox_domains=mysql:/etc/postfix/mysql-domains.cf

postconf -e virtual_mailbox_maps=mysql:/etc/postfix/mysql-mailboxs.cf

postmap -q "support@extmail.org" mysql:/etc/postfix/mysql-alias.cf

postmap -q "extmail.org" mysql:/etc/postfix/mysql-domains.cf

postmap -q "postmaster@extmail.org" mysql:/etc/postfix/mysql-mailboxs.cf

dovecot配置

vi /etc/dovecot/conf.d/10-mail.conf

mail_location = maildir:/home/vmail/%d/%n/Maildir

first_valid_uid = 600

vi /etc/dovecot/conf.d/10-auth.conf

!include auth-sql.conf.ext

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

vi dovecot-sql.conf.ext

driver = mysql 默认不支持mysql 需要安装 yum install dovecot-mysql.x86_64 -y

connect = host=localhost dbname=extmail user=extmail password=extmail

default_pass_scheme = PLAIN

password_query = \

SELECT username, domain, password \

FROM mailbox WHERE username = '%u' AND domain = '%d'

user_query = SELECT maildir, 600 AS uid, 600 AS gid FROM extmail WHERE username = '%u'

ok，完成了，域名访问需要主机记录或者是BIND，访问前台
