postfix 测试邮件服务器,搭建Postfix邮件服务器

1 将sendmail服务停止

[root@mail ~]# service sendmail

stop //停止sendmail服务

Shutting down sm-client: [ OK ]

Shutting down sendmail: [ OK ]

Yum配置

vi /etc/yum.respos.d/rhel-debuginfo.rego

baseurl=file:///cdrom/Server

enabled=1

gpgcheck=1

2 安装配置dns (略)

[root@localhost named]# yum -y

install caching-nameserver bind-chroot

配置请参加DNS的安装与配置

MX记录

mail IN A 172.16.41.180

IN MX 10 MAIL.159.CN.

3 安装postfix

[root@localhost ~]# cd

/media/RHEL_5.5\ i386\ DVD/Server/

[root@localhost Server]# rpm -ivh

postfix-2.3.3-2.1.el5_2.i386.rpm

YUM安装

[root@localhost named]# yum -y

install postfix

4 配置postfix

[root@mail ~]# vim/etc/postfix/main.cf

myhostname = mail.159.cn

mydomain = 159.cn

myorigin = $mydomain

inet_interfaces = all

mydestination = $myhostname, $mydomain

mynetworks = 172.16.42.0, 127.0.0.0/8

relay_domains = 159.cn

wq—退出

service postfix start

[root@mail ~]# vim

/etc/postfix/main.cf

alias_maps =

hash:/etc/aliases

alias_database = hash:/etc/aliases

//检查postfix配置文件中有这两条

[root@mail ~]# vim

/etc/aliases //配置用户别名

mail: mail,mail1,mail2,mail3

[root@mail ~]# postalias

/etc/aliases

[root@mail ~]# postfix

reload

postfix/postfix-script: refreshing the Postfix mail system

6 配置smtp

[root@mail ~]# rpm -qa|grep

sasl

cyrus-sasl-plain-2.1.22-5.el5_4.3

cyrus-sasl-lib-2.1.22-5.el5_4.3

cyrus-sasl-2.1.22-5.el5_4.3

[root@mail ~]# saslauthd

-v

saslauthd 2.1.22

authentication mechanisms: getpwent kerberos5 pam rimap shadow

ldap

[root@mail ~]# vi /etc/sysconfig/saslauthd

MECH=shadow //将认证方式改为shadow

[root@mail ~]# /etc/init.d/saslauthd start

Starting saslauthd: [ OK ]

[root@mail ~]# chkconfig --level 35

saslauthd on

[root@mail ~]# useradd mail1

//创建一个mail1用户，用来测试

[root@mail ~]# passwd

mail1

Changing password for user mail1.

New UNIX password:

BAD PASSWORD: it is too simplistic/systematic

Retype new UNIX password:

passwd: all authentication tokens updated successfully.

[root@mail ~]# testsaslauthd -u

mail1 -p '123456'

0: OK "Success." //验证成功

如果验证不成功

[root@localhost named]# testsaslauthd -u mail1 -p '123456'

0: NO "authentication failed"

请关了防火墙 selinux

在main.cf 中加入如下配置。

[root@localhost ~]# vi

/etc/postfix/main.cf

加到文件尾部

smtpd_sasl_auth_enable = yes

smtpd_sasl_local_domain = ''

smtpd_recipient_restrictions =

permit_mynetworks,permit_sasl_authenticated,

reject_unauth_destination

broken_sasl_auth_clients = yes

smtpd_client_restrictions = permit_sasl_authenticated

smtpd_sasl_security_options = noanonymous

[root@mail ~]# postfix reload //重新加载postfix

postfix/postfix-script: refreshing the Postfix mail system

[root@mail ~]# telnet 172.16.42.165
