4.编译安装postfix

4.1 删除postfix的文件和用户

# find / -user postfix #找到的文件都删除了

# userdel postfix

4.2创建postfix、postdrop用户组和用户

# groupadd -g 2525 postfix

# useradd -g postfix -u 2525 -s /sbin/nologin -M postfix

# groupadd -g 2526 postdrop

# useradd -g postdrop -u 2526 -s /sbin/nologin -M postdrop

4.2开始编译安装

# tar zxvf postfix-3.1..tar.gz

# cd postfix-3.1.

# 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 -lm -L/usr/lib64/sasl2 -lsasl2  -lssl -lcrypto'

# make

# make install

4.3 postfix的一些基础配置设置。一路回车就可以了。

install_root: [/]

tempdir: [/root/Downloads/postfix-3.1.4]

config_directory: [/etc/postfix]

command_directory: [/usr/sbin]

daemon_directory: [/usr/libexec/postfix]

data_directory: [/var/lib/postfix]

html_directory: [no]

mail_owner: [postfix]

mailq_path: [/usr/bin/mailq]

manpage_directory: [/usr/local/man]

注意：这些路径都是要确认本地存在的。可以使用rpm -ql 命令获取rpm包的信息。

4.4 生成别名二进制文件

# newalias

4.5 修改post主配置文件

# vim /etc/postfix/main.cf

修改以下几项为您需要的配置

myhostname = mail.linuxpanda.com

myorigin = linuxpanda.com

mydomain = linuxpanda.com

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

mynetworks = 192.168.137.0/24, 127.0.0.0/8

4.6 为postfix提供sysv服务脚本/etc/rc.d/init.d/postfix

# vim /etc/rc.d/init.d/postfix

#!/bin/bash

#

# postfix      Postfix Mail Transfer Agent

#

# chkconfig: 2345 80 30

# description: Postfix is a Mail Transport Agent, which is the program \

#              that moves mail from one machine to another.

6.为postfix服务开启用户别名支持

6.1在配置文件开启基于hash的别名文件支持

在main.cf中，找到如下指令，而后启用它(即移除前面的#号)：

#alias_maps = hash:/etc/aliases

6.2 添加别名

编辑/etc/alias添加zhaojiedi： zhaojiedi1992行。格式说明，前一个字段为初始目标邮件地址，后一个字段为实际发往的地址。

6.3、将/etc/aliases转换为hash格式：

# postalias  /etc/aliases

6.4 重新启动postfix

# service postfix restart

6.5 测试发送给zhaojiedi 是否转发到zhaojiedi1992邮箱中去。（这里测试跳过）。

7.为postfix开启基于cyrus-sasl的认证功能

7.1检查postfix是否支持了sasl功能

#postconf -a

cyrus

dovecot

7.2 编辑 /etc/postfix/main.cf 加入smtp认证设置信息

#vim /etc/postfix/main.cf

添加以下内容：

############################CYRUS-SASL############################

broken_sasl_auth_clients = yes

smtpd_recipient_restrictions=permit_mynetworks,permit_sasl_authenticated,reject_unauth_destination

smtpd_sasl_auth_enable = yes

smtpd_sasl_local_domain = $myhostname

smtpd_sasl_security_options = noanonymous

smtpd_sasl_path = smtpd

smtpd_banner = Welcome to our $myhostname ESMTP,Warning: Version not Available!

7.3 编辑 /usr/lib/sasl2/smtpd.conf

vim /usr/lib64/sasl2/smtpd.conf

添加如下内容：

pwcheck_method: saslauthd

mech_list: PLAIN LOGIN

7.4 重新加载postfix

#/usr/sbin/postfix reload

7.5 测试sasl配置正确性

!tel

telnet mail.linuxpanda.com 25

mech_list:PLAIN LOGIN

authdaemond_path:/var/spool/authdaemon/socket

9 让postfix支持虚拟域和虚拟用户

9.1编辑/etc/postfix/main.cf

添加如下内容

########################Virtual Mailbox Settings########################

virtual_mailbox_base = /var/mailbox

virtual_mailbox_maps = mysql:/etc/postfix/mysql_virtual_mailbox_maps.cf

virtual_mailbox_domains = mysql:/etc/postfix/mysql_virtual_domains_maps.cf

virtual_alias_domains =

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

virtual_uid_maps = static:2525

virtual_gid_maps = static:2525

virtual_transport = virtual

maildrop_destination_recipient_limit = 1

maildrop_destination_concurrency_limit = 1

注意，启用了虚拟域，需要将需要取消中心域，即注释掉myhostname, mydestination, mydomain, myorigin几行。

9.2使用extman源码目录下docs目录中的extmail.sql和init.sql建立数据库：

# tar zxvf  extman-1.1.tar.gz

# cd extman-1.1/docs

# sed -i 's@TYPE=MyISAM@ENGINE=InnoDB@g' extmail.sql

# mysql -u root -p < extmail.sql

# mysql -u root -p <init.sql

# cp mysql*  /etc/postfix/

9.3授予用户extmail访问extmail数据库的权限

mysql> GRANT all privileges on extmail.* TO extmail@localhost IDENTIFIED BY 'extmail';

mysql> GRANT all privileges on extmail.* TO extmail@127.0.0.1 IDENTIFIED BY 'extmail';

10.配置dovecot

10.1编辑配置文件

# vi /etc/dovecot/conf.d/10-mail.conf        #设置email位置

mail_location = maildir:/var/mailbox/%d/%n/Maildir

# vim /etc/dovecot/conf.d/10-auth.conf       #选择认证方式（mysql认证）

注释掉#!include auth-system.conf.ext行，去掉#!include auth-sql.conf.ext行的注释
#vim /etc/dovecot/dovecot-sql.conf.ext       #配置认证sql语句       
driver = mysql
connect = host=localhost dbname=extmail user=extmail password=extmail
default_pass_scheme = CRYPT
password_query = SELECT username AS user,password AS password FROM mailbox WHERE username = '%u' 
user_query = SELECT maildir, uidnumber AS uid, gidnumber AS gid FROM mailbox WHERE username = '%u'

10.2 重启dovecot

# service dovecot start

# chkconfig dovecot on

11.安装配置extmail

11.1安装

# tar zxvf extmail-1.1.1.tar.gz

# mkdir -pv /var/www/extsuite

# mv extmail-1.1.1 /var/www/extsuite/extmail

# cp /var/www/extsuite/extmail/webmail.cf.default  /var/www/extsuite/extmail/webmail.cf

11.2配置extmail

#vi /var/www/extsuite/extmail/webmail.cf

SYS_MESSAGE_SIZE_LIMIT = 5242880

SYS_MAILDIR_BASE = /var/mailbox

SYS_MYSQL_USER = extmail

SYS_MYSQL_PASS = extmail

SYS_MYSQL_TABLE = mailbox

SYS_MYSQL_ATTR_USERNAME = username

SYS_MYSQL_ATTR_DOMAIN = domain

SYS_MYSQL_ATTR_PASSWD = password

SYS_AUTHLIB_SOCKET = /var/spool/authdaemon/socket

SYS_AUTHLIB_SOCKET =/var/spool/authdaemon/socket

12.apach 配置

12.1编辑/etc/httpd/config/httpd.conf文件

添加如下内容
<VirtualHost *:80>

ServerName mail.magedu.com

DocumentRoot /var/www/extsuite/extmail/html/

ScriptAlias /extmail/cgi /var/www/extsuite/extmail/cgi

Alias /extmail /var/www/extsuite/extmail/html

</VirtualHost>
注释DocumentRoot 行
修改

13.3 创建运行目录

创建其运行时所需的临时目录，并修改其相应的权限：

#mkdir  -pv  /var/www/tmp/extman

#chown postfix.postfix  /var/www/tmp/extman

13.4测试webmail配置如何

打开浏览器输入192.168.137.101/extman 就可以了。

extman默认管理帐号为：root@extmail.org 密码为：extmail*123*

注：如果在后台创建的用户无法调整，编辑/var/www/extsuite/extmail/libs/Ext/Logger/File.pm 注释第45行：printf $fh "$time $host extmail[$$]: $msg\n", @_;

在浏览器192.168.137.101/extmail 页面注册2个用户，测试邮件发送。
