CentOS系统安装Postfix+dovecot+openwebmai的步骤

2017/12/7 15:13:46 | 来源:www.usa-idc.com

一、先卸载sendmain

[root@ser ~]#  yum remove sendmail

二、安装postfix ,dovecot,cyrus-sasl

[root@ser ~]#  yum -y install postfix

[root@ser ~]#  yum -y install dovecot

[root@ser ~]#  yum -y install cyrus-sasl

三、修改postfix的配置文件

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

myhostname = mail.eimam.com

mydomain = eimam.com

myorigin = eimam.com

inet_interfaces =all

mynetworks = 192.168.1.0/240

relay_domains = yjw.com, $mydomain

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

ftp.$mydomain

重启 postfix 服务

[root@ser ~]# service postfix restart

Shutting down postfix:                                    [  OK  ]

Starting postfix:                                             [  OK  ]

[root@ser ~]# chkconfig  postfix on

[root@ser ~]# chkconfig  dovecot on

修改dovecot的配置文件

vim /etc/dovecot.conf

protocols = imap imaps  pop3 pop3s

listen = *

在iptables 里开放25,110,143端口

[root@ser ~]# vim /etc/sysconfig/iptables

-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 110 -j ACCEPT

-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 25 -j ACCEPT

-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 143 -j ACCEPT

重启iptables

[root@ser ~]# service iptables restart

Flushing firewall rules:                               [  OK  ]

Setting chains to policy ACCEPT: filter                [  OK  ]

Unloading iptables modules:                            [  OK  ]

Applying iptables firewall rules:                     [  OK  ]

Loading additional iptables modules: ip_conntrack_netbios_n[  OK  ]ntrack_ftp

[root@ser ~]# chkconfig  saslauthd on

修改 /etc/sysconfig/saslauthd

[root@ser ~]# vim /etc/sysconfig/saslauthd

# Directory in which to place saslauthd's listening socket, pid file, and so

# on.  This directory must already exist.

SOCKETDIR=/var/run/saslauthd

# Mechanism to use when checking passwords.  Run "saslauthd -v" to get a list

# of which mechanism your installation was compiled with the ablity to use.

MECH=shadow

# Additional flags to pass to saslauthd on the command line.  See saslauthd(8)

# for the list of accepted flags.

FLAGS=

修改 /usr/lib/sasl2/smtpd.conf

[root@ser ~]# vim /usr/lib64/sasl2/smtpd.conf

pwcheck_method: saslauthd

测试 saslauthd

[root@ser ~]# service saslauthd  restart

[root@ser ~]# testsaslautd  -u yjw -p '020304'

0: OK "Success."

在postfix 的配置文件中,添加以下内容,使其支持SMTP认证

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

message_size_limit = 1073741824   # 邮件的大小为10M

default_process_limit = 50

default_destination_concurrency_limit = 20

smtpd_sasl_auth_enable = yes

smtpd_sasl_local_domain =  $myhostname

smtpd_sasl_application_name = smtpd

broken_sasl_auth_clients = yes

smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated,reject_unauth_destination

smtpd_client_restrictions = permit_sasl_authenticated

smtpd_sasl_security_options = noanonymous

测试 25端口

[root@ser ~]#  telnet mail.yjw.com 25 

Trying 192.168.1.2...

Connected to mail.yjw.com (192.168.1.2).

Escape character is '^]'.

220 mail.yjw.com ESMTP Postfix

EHLO  163.com

250-mail.yjw.com

250-PIPELINING

250-SIZE 10240000

250-VRFY

250-ETRN

250-AUTH LOGIN PLAIN

250-AUTH=LOGIN PLAIN

250-ENHANCEDSTATUSCODES

250-8BITMIME

250 DSN

quit

221 2.0.0 Bye

Connection closed by foreign host.

[root@ser ~]#

四、安装openwebmail

[root@ser ~]# vim /etc/yum.repos.d/openwebmail.repo 

[openwebmail]

## Thomas Chung

## 2008.05.29

name=Openwebmail for Fedora or Enterprise Linux

baseurl=http://openwebmail.org/openwebmail/download/redhat/rpm/release/

enabled=1

gpgcheck=1

gpgkey=http://openwebmail.org/openwebmail/download/redhat/rpm/release/RPM-GPG-KEY-openwebmail

#metadata_expire=0

若这样安装不成功,先安装 perl-Text-Iconv-1.4-1.2.el4.rf.i386.rpm

[root@ser ~]#  yum -y  install openwebmail

[root@ser ~]# cd /var/www/cgi-bin/openwebmail/

[root@ser openwebmail]# ./openwebmail-tool.pl  --init  #出现Y/N时 ,按N.

修改openwebmail 的一些配置文件

[root@ser etc]# vim dbm.conf

dbm_ext                 .db

dbmopen_ext             .db

dbmopen_haslock         no

[root@ser etc]]# cd defaults/

[root@ser defaults]#  vim dbm.conf

dbm_ext                 .db

dbmopen_ext             .db

dbmopen_haslock         yes

smtpserver  192.168.1.2

[root@ser defaults]#  vim openwebmail.conf

domainnames             yjw.com

smtpserver              192.168.1.2

authpop3_server         192.168.1.2

再次初始化openwebmail

[root@ser defaults]# cd  ../../openwebmail-tool.pl  --init 

出现Y/N 时,按Y。

把Postfix+Dovecot+Openwebmail 三者个格式统一下就行了

1.postfix 配置 main.cf

mail_spool_directory = /var/spool/mail

2.Dovecot 配置 Dovecot.conf

mail_location = mbox:~/mail:INBOX=/var/spool/mail/%u

3.Openwebmail.conf

mailspooldir /var/spool/mail

五、安装httpd

[root@ser ~]# yum - y install httpd

[root@ser ~]# chkconfig httpd on

[root@ser ~]# service httpd restart

Stopping httpd:                                            [  OK  ]

Starting httpd:                                            [  OK  ]

[root@ser ~]# vim /etc/httpd/conf/httpd.conf

ServerAdmin

root@yjw.com

ServerName  mail.yjw.com:80

AddHandler cgi-script .cgi .pl

六、登陆openwebmail

在IE 中输入  mail.yjw.com/cgi-bin/openwebmail/openwebmail.pl,  这个地址是不是很长,那么我们来点短点的

在  httpd的 配置文件中添加 下面 内容:

ScriptAlias  /mail    /var/www/cgi-bin/openwebmail/openwebmail.pl

这样在IE 中直接输入

mail.yjw.com/mail

七、安装反垃圾邮件软件,MailScanner

到MailScanner .org 上下载MailScanner-4.75.11-1.rpm.tar.gz

[root@ser ~]#  tar zxvf  MailScanner-4.75.11-1.rpm.tar.gz

[root@ser ~]#  cd  MailScanner-4.75.11

[root@ser MailScanner-4.75.11-1]# ./install.sh    # 安装

安装 spamassassin

先检查您的系统内是否已经安装SpamAssassin软件包。在文本终端中输入:

[root@ser ~]#          rpm -qa | grep spamassassin

spamassassin-3.1.9-1.el5

下载Mail-SpamAssassin-3.2.5.tar.gz

[root@ser ~]#tar  -zxvf Mail-SpamAssassin-3.2.5.tar.gz

[root@ser ~]# cd Mail-SpamAssassin-3.2.5

[root@ser ~]# perl Makefile.PL

[root@ser ~]# make

[root@ser ~]#  make install

打开/etc/MailScanner/目录中的MailScanner.conf文件,主要说明修改的关键部分:

%org-name%  = yjw.com

%org-long-name% = yjw

web-site% = mail.yjw.com

Run As User = postfix

Run As Group = postfix

Incoming Queue Dir = /var/spool/postfix/hold

Outgoing Queue Dir = /var/spool/postfix/incoming

MTA = postfix

Incoming Work Group = postfix

Quarantine User = postfix 

Quarantine Group = postfix

Always Include SpamAssassin Report = yes

SpamAssassin User State Dir = /var/spool/MailScanner/spamassassin

SpamAssassin Install Prefix = /usr/bin

Log Speed = yes

Log Spam = yes

Log Silent Viruses = yes

Phishing Modify Subject = yes

更改incoming,quarantine 两个2个目录

[root@ser ~]# service spamassassin restart

[root@ser ~]# service spamassassin on

[root@ser ~]# service MailScanner  restart

[root@ser ~]# service MailScanner  on

[root@ser ~]# chown -R postfix:postfix /var/spool/MailScanner/*

[root@ser ~]# cd /var/spool/MailScanner/

[root@ser MailScanner]# ll

drwxr-xr-x 4 postfix postfix 4096 Apr 30 16:56 incoming

drwxr-xr-x 3 postfix postfix 4096 Apr 29 19:10 quarantine

drwx------ 2 postfix postfix 4096 Apr 30 15:58 spamassassin

在/etc/postfix/header_checks 中增加一句话:

[root@ser ~]# vi  /etc/postfix/header_checks

/^Received:/    HOLD 

设置中文邮件过滤规则

[root@ser ~]# wget -N -P

http://www.ccert.edn.cn/spam/sa/Chiese_rules.cf

 /usr/share/spamassassin

使用计划任务来更新规则

[root@ser ~]#  crontab  -e

0 0 1 * * wget - N  -P   /usr/share/spamassassin

http://www.ccert.edu.cn/spam/sa/Chiness_rules.cf

;  /etc/init.d/spamassassin restart

八、登陆openwebmail, 测试 收信,发信是否正常

[root@ser ~]# useradd  tom

[root@ser ~]# passwd  tom

tom

tom

[root@ser ~]# useradd yjw

[root@ser ~]# passwd  yjw
