centos/redhat 上安装邮件系统(extmail) V0.1

    Author:fengyong 2008-08-31

    请尊重作者劳动,复制转载此文档时,请保留或添加文档来源。版权:开源易有(

    

    )

    一、简介:

    本文以最简单,最方便的方法在centos 5.2 上安装一个全功能的邮件系统,此文适合REDHAT所有系列,在文中,能用RPM 安装的,我们将采用rpm 安装,如果rpm没有的,我们将创建自己的rpm。部分软件简介:

    1、AMP ---apache(web服务) 、mysql(数据库)、php(非必需) 的简称

    2、postfix --mta 邮件系统核心

    3、courier-authlib--一个为courier-imap,maildrop,sasl2 提供用户信息的后台进程序

    4、courier-imap --提供pop3,pop3s,imap,imaps 服务的程序

    5、amavisd-new --提供内容过滤

    6、clamav -- 著名的杀毒软件

    7、extmail --一个著名的webmail程序

    8、extman --与extmail集成的后台管理程序

    9、slockd --一个基于smtp阶段的反垃圾邮件程序

    10、vhmgr --由本文作者编写,用于管理apache,ftp,mysql 的虚拟主机管理程序。

    安装环境:

    centos 5.2

    域名机器名:mail.yiyou.org mail.icaot.com

    域名:yiyou.org icaot.com

    二、安装系统

    安装系统时,选择“customize software selection”(自定义安装),在package group selection 对话框里选择:

    

  • base 我选择的是最小安装base 所以一些编译器什么的都没安装。

        

  • devlopment libraries 用的是centos.ustc.edu.cn的源

        

  • development tools

        

  • editors

        

  • text-base internet

        其它不选择。

        在setup agnet(或进入系统后运行setup) 里选择firewall configuration

        将security level 与SELinux

        改为disabled,目的是为了避免在安装调试时产生不必要的麻烦,在系统安装完成后,可以自己去调试安全部分,在这里将不作详细介绍。

        配置yum,在本文中使用的是网通线路,所以选择了 作为安装镜像。

        [root@localhost ~]# cd /etc/yum.repos.d/

        [root@localhost yum.repos.d]# wget CentOS-Base.repo.ta139

        [root@localhost yum.repos.d]# mv CentOS-Base.repo CentOS-Base.repo.bak

        [root@localhost yum.repos.d]# mv CentOS-Base.repo.ta139 CentOS-Base.repo

        三、安装软件

        1、安装AMP

         [root@localhost ~]# yum -y install httpd httpd-devel mysql mysql-devel mysql-server php php-xml php-cli php-pdo php-mbstring php-mcrypt php-gd php-common php-devel php-mysql

        修改启动配置并启动

        [root@localhost ~]# chkconfig --level 345 mysqld on

        [root@localhost ~]# chkconfig --level 345 httpd on

        [root@localhost ~]# service mysqld start

        [root@localhost ~]# service httpd start

        2、安装phpmyadmin

        注意:可以选择自己需要的版本 我没有安装phpmyadmin

        [root@localhost ~]# wget

        [root@localhost ~]# tar xjf phpMyAdmin-2.11.9-all-languages-utf-8-only.tar.bz2

        [root@localhost ~]# mv phpMyAdmin-2.11.9-all-languages-utf-8-only /var/www/html/phpmyadmin

        [root@localhost phpmyadmin]# cp config.sample.inc.php config.inc.php

        编辑config.inc.php 改为下面,字符串是任意的。 $cfg['blowfish_secret'] = 'skssiwksksie'; /* YOU MUST FILL IN THIS FOR COOKIE AUTH! */

        进入phpmyadmin 请马上修改mysql root 用户的密码。

        3、导入extman 后台数据库

        将extmail/extman/slockd 上传到服务器,可以使用ftp/winscp 上传

        [root@localhost ~]# tar zxf extman-0.2.5b1.tar.gz

        [root@localhost ~]# cd extman-0.2.5b1/docs/

        [root@localhost docs]# mysql -uroot -p

        如何使用了phpmyadmin改了root 密码,记得输入密码,如果密码为空,请按回车。

        4、RPM 简介

        下面我们将采用rpm 的方式安装软件

        /usr/src/redhat/SPEC spec 文件夹,通常是rpm文件夹

        /usr/src/redhat/RPMS 是生成rpm 的文件,下面还有i368,i486 等子文件夹,一般我们用i386 架构

        /usr/src/redhat/SOURCE 源文件文件夹

        为了安装时切换目录的方便,我们将目录存放到一个shell变量里。

        [root@localhost ~]# export RPMS=/usr/src/redhat/RPMS

        [root@localhost ~]# export SOURCE=/usr/src/redhat/SOURCES

        [root@localhost ~]# export SPEC=/usr/src/redhat/SPECS

        在下面安装过程中,大家要记住cd $RPMS 与cd /usr/src/redhat/RPMS 的目的是一样的,只是shell变量的替换。

        5、安装authlib

        A、安装依懒的包[root@localhost ~]# yum -y install postgresql-devel expect libtool-ltdl-devel

        [root@localhost ~]# wget

        [root@localhost ~]# tar xjf courier-authlib-0.61.0.tar.bz2

        [root@localhost ~]# cd courier-authlib-0.61.0

        [root@localhost courier-authlib-0.61.0]# cp courier-authlib.spec $SPEC

        [root@localhost courier-authlib-0.61.0]# cd ..

        [root@localhost ~]# cp courier-authlib-0.61.0.tar.bz2 $SOURCE

        [root@localhost ~]# cd $SPEC

        [root@localhost SPECS]# rpmbuild -bb courier-authlib.spec (创建rpm文件)

        B、安装生成的rpm[root@localhost SPECS]# cd $RPMS/i386

        [root@localhost i386]# rpm -ivh courier-authlib-0.61.0-1.i386.rpm

        [root@localhost i386]# rpm -ivh courier-authlib-devel-0.61.0-1.i386.rpm

        [root@localhost i386]# rpm -ivh courier-authlib-mysql-0.61.0-1.i386.rpm

        C、配置authlibdaemon[root@localhost i386]# cd /etc/authlib/

        [root@localhost authlib]# mv authdaemonrc authdaemonrc.bak

        [root@localhost authlib]# vim authdaemonrc

        输入下面的内容: authmodulelist="authmysql"

        authmodulelistorig="authmysql"

        daemons=10

        authdaemonvar=/var/spool/authdaemon

        DEBUG_LOGIN=2

        DEFAULTOPTIONS="wbnodsn=1"

        LOGGEROPTS=""

        D、配置authmysqlrc [root@localhost authlib]# mv authmysqlrc authmysqlrc.bak

        [root@localhost authlib]# vim authmysqlrc

        输入下面的内容: MYSQL_SERVER localhost

        MYSQL_USERNAME extmail

        MYSQL_PASSWORD extmail

        MYSQL_PORT 0

        MYSQL_SOCKET /var/lib/mysql/mysql.sock

        MYSQL_OPT 0

        MYSQL_DATABASE extmail

        MYSQL_SELECT_CLAUSE SELECT username,password,"",uidnumber,gidnumber,\

         CONCAT('/home/data/domains/',homedir), \

         CONCAT('/home/data/domains/',maildir), \

         quota, \

         name \

         FROM mailbox \

         WHERE username = '$(local_part)@$(domain)'

        E、启动authlib[root@localhost ~]# service courier-authlib start

        Starting Courier authentication services: authdaemond

        [root@localhost ~]# chmod 777 /var/spool/authdaemon/

        6、安装courier-imap

        由于courier-imap 不能用root身份生成rpm那么我们新建一个普通用户,并创建一个rpm环境

        [root@localhost ~]# useradd yiyou 在这里添加自己的用户

        软件包依懒需要安装openldap-server,rpm创建完成后可以删除

        [root@localhost ~]# yum -y install openldap-servers

        [root@localhost ~]# su - yiyou [yiyou@localhost ~]$ mkdir -p rpm/{BUILD,RPMS,SOURCES,SPECS,SRPMS}

        [yiyou@localhost ~]$ vim ~/.rpmmacros

        输入内容: %_topdir /home/yiyou/rpm

        [yiyou@localhost ~]$ wget

        [yiyou@localhost ~]$ cp courier-imap-4.4.1.tar.bz2 rpm/SOURCES/

        [yiyou@localhost ~]$ tar xjf courier-imap-4.4.1.tar.bz2

        [yiyou@localhost ~]$ cd courier-imap-4.4.1

        [yiyou@localhost courier-imap-4.4.1]$ cp courier-imap.spec ../rpm/SPECS/

        [yiyou@localhost courier-imap-4.4.1]$ cd ../rpm/SPECS/

        编辑courier-imap.spec 将下面的内容: %if %suse_version

        BuildPreReq: rpm >= 3.0.5 /usr/bin/sed openldap2 openldap2-devel %([ %{suse_version} -gt 819 ] && echo /usr/include/fam.h)

        %else

        BuildPreReq: rpm >= 4.0.2 sed /usr/include/fam.h openldap-devel openldap-servers

        %endif

        改为:

        %if %suse_version 在这里好像提示没有安装openldap-server yum install openldap* 还真没装

        BuildPreReq: rpm >= 3.0.5 /usr/bin/sed openldap2 openldap2-devel

        %else

        BuildPreReq: rpm >= 4.0.2 sed openldap-devel openldap-servers

        %endif

        创建rpm [yiyou@localhost SPECS]$ rpmbuild -bb courier-imap.spec

        完成rpm后,输入exit退出当前用户。

        [root@localhost ~]# rpm -ivh /home/yiyou/rpm/RPMS/i386/courier-imap-4.4.1-1.i386.rpm

        [root@localhost ~]# service courier-imap start

        7、安装cyrus-sasl

        A、安装SRPM[root@localhost ~]# wget ftp://194.199.20.114/linux/fedora/updates/8/SRPMS/cyrus-sasl-2.1.22-8.fc8.src.rpm

        [root@localhost ~]# rpm -ivh cyrus-sasl-2.1.22-8.fc8.src.rpm

        [root@localhost ~]# cd $SPEC

        编辑cyrus-sasl.spec 将下面:

        # Bundling copy of Berkeley DB, for sasldb support.

        topdir=`pwd`

        pushd db-%{db_version}/build_unix

        ../dist/configure \

         --with-mutex=UNIX/fcntl --disable-shared --enable-static --with-pic \

         --with-uniquename=_cyrus_sasl_sasldb_rh \

         --prefix=${topdir}/db-instroot \

         --includedir=${topdir}/db-instroot/include \

         --libdir=${topdir}/db-instroot/lib

        改为:

        # Bundling copy of Berkeley DB, for sasldb support.

        topdir=`pwd`

        pushd db-%{db_version}/build_unix

        ../dist/configure \

         --with-mutex=UNIX/fcntl --disable-shared --enable-static --with-pic \

         --with-uniquename=_cyrus_sasl_sasldb_rh \

         --prefix=${topdir}/db-instroot \

         --includedir=${topdir}/db-instroot/include \

         --libdir=${topdir}/db-instroot/lib \

         --with-authdaemond=/var/spool/authdaemon提示下面的故障的请看上面--with-authdaemond=/var/spool/authdaemon: No such file or directory 少了各斜杠所以看不到这个选项Cannot enable LDAPDB plugin: Could not locate OpenLDAP因为没有安装oepnldap 客户端什么的。装上就行了

        B、生成rpm[root@localhost SPECS]# rpmbuild -bb cyrus-sasl.spec

        [root@localhost RPMS]# cd $RPMS/i386

        [root@localhost i386]# rpm -e --nodeps cyrus-sasl-devel cyrus-sasl-plain cyrus-sasl cyrus-sasl-lib (如果这些包存在)

        [root@localhost i386]# rpm -ihv cyrus-sasl-lib-2.1.22-8.i386.rpm

        [root@localhost i386]# rpm -ihv cyrus-sasl-2.1.22-8.i386.rpm

        [root@localhost i386]# rpm -ihv cyrus-sasl-plain-2.1.22-8.i386.rpm

        C、配置sasl2

        创建/usr/lib/sasl2/smtpd.conf 文件,输入下面的内容: pwcheck_method:authdaemond

        log_level:3

        mech_list:PLAIN LOGIN

        authdaemond_path:/var/spool/authdaemon/socket

        8、安装postfix

        A、下载软件包[root@localhost i386]# cd

        [root@localhost ~]# wget

        [root@localhost ~]# rpm -ivh postfix-2.5.4-2.src.rpm

        [root@localhost ~]# cd $SPEC

        编辑postfix.spec 修改下面的选项 %define distribution rhel-5.0

        %define with_mysql_redhat 1

        %define with_sasl 2

        %define with_vda 1

        B、创建rpm [root@localhost SPECS]# rpmbuild -bb postfix.spec

        [root@localhost RPMS]# cd $RPMS/i386

        [root@localhost i386]# rpm -ivh postfix-2.5.4-2.rhel4.i386.rpm

        C、切换mta [root@localhost i386]# alternatives --config mta (选择2,postfix)

        [root@localhost i386]# rpm -e sendmail

        [root@localhost i386]# cd /usr/sbin/

        [root@localhost sbin]# mv sendmail sendmail.bak

        [root@localhost sbin]# newaliases

        [root@localhost sbin]# ln -s sendmail.postfix sendmail

        D、配置postfix [root@localhost ~]# cd /etc/postfix/

        [root@localhost postfix]# mv main.cf main.cf.bak

        [root@localhost postfix]# vim main.cf

        输入下面的内容: queue_directory = /var/spool/postfix

        command_directory = /usr/sbin

        daemon_directory = /usr/libexec/postfix

        data_directory = /var/lib/postfix

        mail_owner = postfix

        unknown_local_recipient_reject_code = 550

        debug_peer_level = 2

        debugger_command =

         PATH=/bin:/usr/bin:/usr/local/bin:/usr/X11R6/bin

         ddd $daemon_directory/$process_name $process_id & sleep 5

        sendmail_path = /usr/sbin/sendmail.postfix

        newaliases_path = /usr/bin/newaliases.postfix

        mailq_path = /usr/bin/mailq.postfix

        setgid_group = postdrop

        html_directory = /usr/share/doc/postfix-2.5.2-documentation/html

        manpage_directory = /usr/share/man

        sample_directory = /etc/postfix

        readme_directory = /usr/share/doc/postfix-2.5.2-documentation/readme

        alias_database = hash:/etc/postfix/aliases

        alias_maps = hash:/etc/postfix/aliases

        myhostname = mail.yiyou.org

        mydomain = yiyou.org

        mydestination = $myhostname

        smtpd_banner = yiyou.org ESMTP Mail System

        message_size_limit = 14680064

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

        virtual_mailbox_base = /home/data/domains

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

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

        virtual_mailbox_limit_maps = mysql:/etc/postfix/mysql_virtual_limit_maps.cf

        virtual_transport = maildrop:

        maildrop_destination_recipient_limit = 1

        #sasl

        smtpd_sasl_auth_enable = yes

        smtpd_sasl2_auth_enable = yes

        smtpd_sasl_security_options = noanonymous

        broken_sasl_auth_clients = yes

        smtpd_recipient_restrictions =

         permit_mynetworks,

         permit_sasl_authenticated,

         reject_unauth_destination,

         reject_unauth_pipelining,

         reject_invalid_hostname

        复制extman/docs 目录的cf 文件到/etc/postfix [root@localhost postfix]# cp /root/extman-0.2.5b1/docs/mysql_virtual_* .

        因为配置文件的用户、密码与数据库时一样,所以不用修改。 [root@localhost postfix]# service postfix start

        9、安装maildrop

        A、下载生成RPM[root@localhost postfix]# cd

        [root@localhost ~]# wget

        [root@localhost ~]# cp maildrop-2.0.4.tar.bz2 $SOURCE

        [root@localhost ~]# tar xjf maildrop-2.0.4.tar.bz2

        [root@localhost ~]# cd maildrop-2.0.4

        [root@localhost maildrop-2.0.4]# cp maildrop.spec $SPEC

        [root@localhost maildrop-2.0.4]# cd $SPEC

        编辑maildrop.spec 把下面: BuildRequires: /usr/include/fam.h gdbm-devel pcre-devel

        改为: BuildRequires: gdbm-devel pcre-devel

        把下面: %configure --with-devel --enable-userdb --enable-maildirquota \

        --enable-syslog=1 --enable-trusted-users='root mail daemon postmaster qmaild mmdf' \

        --enable-restrict-trusted=0 \

        --enable-sendmail=/usr/sbin/sendmail

        改为: %configure --with-devel --enable-userdb --enable-maildirquota \

        --enable-syslog=1 --enable-trusted-users='root mail daemon postmaster qmaild mmdf' \

        --enable-restrict-trusted=0 --enable-sendmail=/usr/sbin/sendmail \

        --enable-authlib

        B、创建安装maildrop rpm [root@localhost SPECS]# yum -y install pcre-devel

        [root@localhost SPECS]# rpmbuild -bb maildrop.spec

        [root@localhost SPECS]# cd $RPMS/i386

        [root@localhost i386]# rpm -ivh maildrop-2.0.4-1.i386.rpm

        C、添加虚似用户及创建目录 [root@localhost i386]# cd 在这里提示已经添加了用户 应该是安装postfix的时候创建的用户

        [root@localhost ~]# groupadd -g 1000 vgroup

        [root@localhost ~]# useradd -g 1000 -u 1000 -s /sbin/nologin -d /dev/null vuser

        编辑/etc/postfix/master.cf ,加入下面的内容: maildrop unix - n n - - pipe

         flags=DRhu user=vuser argv=/usr/bin/maildrop -d ${user}@${nexthop} ${recipient} ${user} ${extension} ${nexthop}

        D、创建邮件存储目录 [root@localhost ~]# mkdir -p /home/data/domains/extmail.org/postmaster

        [root@localhost ~]# maildirmake /home/data/domains/extmail.org/postmaster/Maildir

        [root@localhost ~]# chown -R vuser:vgroup /home/data/domains/

        E、测试maildrop [root@localhost ~]# echo "test" | maildrop -V 10 -d postmaster@extmail.org

        maildrop: authlib: groupid=1000

        maildrop: authlib: userid=1000 这里改成自己相应的

        maildrop: authlib:

        [email=logname=postmaster@extmail.org]logname=postmaster@extmail.org[/email]

        ,home=/home/data/domains/extmail.org/postmaster, mail=/home/data/domains/extmail.org/postmaster/Maildir/

        maildrop: Changing to /home/data/domains/extmail.org/postmaster

        Message start at 0 bytes, envelope sender=postmaster@extmail.org

        maildrop: Attempting .mailfilter

        maildrop: Delivery complete.

        出现上以信息说明authlib,maildrop 工作正常

        F、测试pop3[root@localhost ~]# telnet localhost 110

        Trying 127.0.0.1...

        Connected to localhost.localdomain (127.0.0.1).

        Escape character is '^]'.

        +OK Hello there.

        user postmaster@extmail.org

        +OK Password required.

        pass extmail

        +OK logged in.

        +OK 6 octets follow.

        test

        .

        quit

        +OK Bye-bye.

        Connection closed by foreign host.

        G、测试postfix [root@localhost ~]# perl -MMIME::Base64 -e 'print encode_base64("postmaster\@extmail.org");'

        cG9zdG1hc3RlckBleHRtYWlsLm9yZw==

        [root@localhost ~]# perl -MMIME::Base64 -e 'print encode_base64("extmail");'

        ZXh0bWFpbA==

        [root@localhost ~]# service postfix restart (重启一下)

        [root@localhost ~]# telnet localhost 25

        Trying 127.0.0.1...

        Connected to localhost.localdomain (127.0.0.1).

        235 2.7.0 Authentication successful

        quit

        221 2.0.0 Bye

        Connection closed by foreign host

        10、安装amavisd-new

        编辑/etc/yum.repos.d/CentOS-Base.repo 加入下面的内容: [dag]

        name=Dag RPM Repostory for Red Hat Enterprise Linux

        baseurl=

        gpgcheck=1

        enabled=1

        gpgkey=

        [root@localhost ~]# yum -y install clamav clamav-db clamd clamav-devel amavisd-new

        编辑/etc/amavisd.conf,修改下面的内容 这个源超级慢啊。以前很快的 ,不知道为何现在很慢呢$mydomain = 'yiyou.org'; # a convenient default for other settings

        把下面内容去掉注释,并修改为下面

         ['ClamAV-clamd',

         \&ask_daemon, ["CONTSCAN {}\n", "/tmp/clamd.socket"],

         qr/\bOK$/, qr/\bFOUND$/,

         qr/^.*?: (?!Infected Archive)(.*) FOUND$/ ],

        $final_virus_destiny = D_DISCARD;

        $final_banned_destiny = D_BOUNCE;

        $final_spam_destiny = D_PASS;/这里原来是bounce直接拒绝,我说我从163发信直接收不到,,分提高到7.多都不行改成pass

        $final_bad_header_destiny = D_PASS;

        [root@localhost ~]# usermod -G amavis clamav

        [root@localhost ~]# service clamd start

        在/etc/postfix/master.cf 增加下面的内容: smtp-amavis unix - - n - 4 smtp 这里不知道是什么意思。。改天问问键盘

         -o smtp_data_done_timeout=1200

         -o smtp_send_xforward_command=yes

         -o disable_dns_lookups=yes

        127.0.0.1:10025 inet n - n - - smtpd

         -o content_filter=

         -o local_recipient_maps=

         -o relay_recipient_maps=

         -o smtpd_restriction_classes=

         -o smtpd_helo_restrictions=

         -o smtpd_sender_restrictions=

         -o smtpd_recipient_restrictions=permit_mynetworks,reject

         -o mynetworks=127.0.0.0/8

         -o strict_rfc821_envelopes=yes

         -o smtpd_error_sleep_time=0

         -o smtpd_soft_error_limit=1001

         -o smtpd_hard_error_limit=1000

         -o receive_override_options=no_header_body_checks

        在/etc/postfix/main.cf 加入下面的内容 content_filter = smtp-amavis:[localhost]:10024

        [root@localhost ~]# service postfix reload

        11、安装extman/extmail

        A、配置apache

        修改/etc/httpd/conf/httpd.conf,将下面的选项改为: User vuser

        Group vgroup

        [root@localhost ~]# cd /etc/httpd/conf.d/

        [root@localhost conf.d]# vim extmail.conf

        输入下面的内容: Alias /extman/cgi/ /var/www/extsuite/extman/cgi/

        Alias /extman /var/www/extsuite/extman/html/

        SetHandler cgi-script

        Options +ExecCGI

        # config for ExtMail

        Alias /extmail/cgi/ /var/www/extsuite/extmail/cgi/

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

        SetHandler cgi-script

        Options +ExecCGI

        [root@localhost ~]# mkdir /var/www/extsuite

        [root@localhost ~]# tar zxf extmail-1.0.5b1.tar.gz

        [root@localhost ~]# cp -r extmail-1.0.5b1 /var/www/extsuite/extmail

        [root@localhost ~]# cp -r extman-0.2.5b1 /var/www/extsuite/extman

        B、配置extmail参数 [root@localhost ~]# cd /var/www/extsuite/extmail/

        [root@localhost extmail]# cp webmail.cf.default webmail.cf

        修改webmail.cf 下面的选项 SYS_SESS_DIR = /tmp/extmail

        SYS_MAILDIR_BASE = /home/data/domains

        SYS_MYSQL_USER = extmail

        SYS_MYSQL_PASS = extmail

        C、配置extman参数 [root@localhost extmail]# cd /var/www/extsuite/extman/

        修改webman.cf 下面的选项: SYS_MAILDIR_BASE = /home/data/domains

        D、创建session 目录 [root@localhost extman]# mkdir /tmp/{extman,extmail}

        [root@localhost extman]# chown vuser:vgroup /tmp/ext*

        E、配置后台日志分析工具 [root@localhost addon]# cd /var/www/extsuite/extman/addon/

        [root@localhost addon]# cp -r mailgraph_ext /usr/local/

        将下面的内容加入/etc/rc.local /usr/local/mailgraph_ext/mailgraph-init start

        /usr/local/mailgraph_ext/qmonitor-init start

        安装所依懒的软件包 [root@localhost mailgraph_ext]# yum -y install rrdtool perl-rrdtool perl-GD perl-File-Tail

        F、启动后台进程 [root@localhost mailgraph_ext]# /usr/local/mailgraph_ext/qmonitor-init start

        Starting queue statistics grapher: qmonitor

        [root@localhost mailgraph_ext]# /usr/local/mailgraph_ext/mailgraph-init start

        Starting mail statistics grapher: mailgraph_ext

        G、访问extmail/extman

        打开浏览器,输入 注意:your_ip_address 为你实际的ip

        第一个测试用户为:postmaster 密码:extmail 域:extmail

        打开浏览器,输入

        extman root 用户为:root@extmail.org 密码为:extmail*123*

        注意:进入系统后要修改密码及找回密码的提示问题、答案。

        12、安装slockd 这里我还没装准备试试dspam

        slockd 是一个基于策略的垃圾邮件软件,很多用户反映使用后,反垃圾效果非常明显,但是有部分用户由于对该软件的使用,特性不了解,而产生了很多麻烦。

        所在在此建议,如果你对该软件不了解,或者系统里的垃圾邮件少,可以暂时不安装。 [root@localhost ~]# tar zxf slockd-0.2beta1.tar.gz

        [root@localhost ~]# cp -r slockd-0.2beta1 /usr/local/slockd

        [root@localhost ~]# cd /usr/local/slockd

        将下面的内容加入/etc/rc.local /usr/local/slockd/slockd-init start

        [root@localhost slockd]# vim config/main.cf (编辑slockd/config/main.cf)修改下面的内容 setsid 1 (去掉注释,让程序成为后台进程)

        修改/etc/postfix/main.cf 将原先的内容: smtpd_recipient_restrictions =

         permit_mynetworks,

         permit_sasl_authenticated,

         reject_unauth_destination,
