RHEL 5.0 postfix+dovecot+openwebmail 服务器

 

实验环境 VM 6.0 ,RHEL 5.0 ,内核 2.6.18,本地YUN源  DNS 服务器
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
四、 修改postfix的配置文件
[root@ser ~]# vim /etc/postfix/main.cf
 
myhostname = mail.yjw.com
mydomain = yjw.com
myorigin = yjw.com
inet_interfaces =all
mynetworks = 192.168.1.0/24
relay_domains = yjw.com, $mydomain
mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain,       mail.$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 ~]# yum -y install cyrus-sasl

[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/lib/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).

[root@ser ~]#

五、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=
enabled=1
gpgcheck=1
gpgkey=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。

六、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
ServerName  mail.yjw.com:80
AddHandler cgi-script .cgi .pl

七、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
八、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   /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 ;  /etc/init.d/spamassassin restart
九、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
020304
020304
我在系统中测试收信发信是没有问题的，可以给163.com等域发邮件，系统内的用户对发是没有问题的。至此，一个多功能邮件就搭建完成。相关的文档可以在 baidu ,google 上查找。
