前言

1、感谢HZQBBC 多年来的帮助，让我对LINUX /UNIX 有所了解。

2、本人文笔不好，欢迎拍砖。

3、本文通过一步一个软件，一个软件一次性设置的方式让你了解如何组建一个邮件系统。

4、建议：良好的电脑基础会使你事半功倍，至少你要明白互联网上的一些常用服务的原理，如：web/ftp/dns/mail(mta/mua/mda)及了解什么是TCP/IP协议。

5、对了BSD 操作不熟的兄弟建议看Freebsd 的Handbook。

http://cnsnap.cn.freebsd.org/doc/zh_CN.GB2312/books/handbook/index.html

6、对于英文不太好的兄弟建议使用IBM 智能词典。

http://www.google.com/search?hl=zh-CN&q=IBM%E6%99%BA%E8%83%BD%E8%AF%8D%E5%85%B8&lr=

7、要多想多做多动脑（大脑生来就是为了思考的，不用会生锈），要懂得如何去使用google/baidu 寻找你需要的东西，可能你遇到的问题人家已经遇过并解决了。

8、认真观察安装过程、日志文件是寻找错误的关键。

9、古语云：冰冻三尺非一日之寒，当你第N 次安装失败时，千万别恢心，成功往往就与你擦肩而过。回头认真看文档，回想自己的操作，整理好思路。相信自己一定会成功。

10、FreeBSD 通过ports 安装总是花上不少时间在下载文件及编译，建议你多喝水或为自己准备一杯咖啡，编译的时候走走运动一下也是个不错的主意。

最后献上我用了六年的座右铭：靠山山倒，靠人人倒，靠自己最好！

更新：

1、接上编<Freebsd 6.0 +Postfix + MySQL+Cyrus-SASL2 +Courier-IMAP + Clamav+Mailscanner+Extman+Extmail>对内容进行了修改。

2、把mailscanner 换成amavisd-new。

3、增加了maildrop 作为邮件的投递代理。

4、更详细的安装过程。

5、以HTML 方式发布，方便兄弟们复制命令。

6、去掉了zend/ftp/openssl 的安装。

7、加入了atni-spam.org.cn 的cdl服务从而更有效拒绝垃圾邮件。

快速索引

一、设置你的DNS

二、安装Freebsd

三、安装mysql

四、安装apahce

五、安装邮件系统

六、测试系统

七、安装反垃圾邮件

八、安装extmail/extman

一、设置你的DNS

很多人经常问为什么我的邮件服务器向163.com /sina.com/yahoo.com.cn...都能收到，为什么回复的邮件却收不到，原因很简单，因为这些服务器不能找到你的域名的A记录或MX 记录。很多人在安装时使用的域都是不合法的域名，即未经注册的DNS FQDN（完全限定名）。如果你没有申请合法的域名，可以到 comexe.cn 3322.org 申请一个动态域名来收发邮件。

本例中以 extmail.org 这个域为例，主机名为mail ,邮件服务器建立在DDNS 之上。
打开windows 的CMD 使用nslookup 查询extmail.org 的MX记录，如果你自己拥有固定IP可以创建自己的DNS，如果你使用的是新网或其它域名供应商，进入后台添加一个记录即可，供体参考DNS 相关的内容。

 C:\>nslookup -type=mx extmail.org 221.4.66.66Server:  ns2.cnc-gd.netAddress:  221.4.66.66DNS request timed out.    timeout was 2 seconds.Non-authoritative answer:extmail.org     MX preference = 20, mail exchanger = mx.extmail.orgextmail.org     nameserver = ns2.xinnetdns.comextmail.org     nameserver = ns.xinnet.cnextmail.org     nameserver = ns.xinnetdns.comextmail.org     nameserver = ns2.xinnet.cnmx.extmail.org  internet address = 210.21.119.139ns.xinnet.cn    internet address = 210.51.171.209ns.xinnetdns.com        internet address = 210.51.170.66ns2.xinnet.cn   internet address = 210.51.170.67ns2.xinnetdns.com       internet address = 210.51.170.67

作为windows 高手的你，这点小事难不到你吧。

二、安装Freebsd

A、系统分区

很多人在使用自己的作业系统时，不知道如何对系统分区，对于分区方案没有最好的，只是跟据自己的情况去分。
下面是我的分区方案。

硬盘为120G ，/（根）1G 左右就差不多了，但考滤到/root 工作目录也在这里，所以分大一点。

/home/data 主要是用来存放Email /ftp用户的数据

/tmp 1G 也是考虑到临时文件多，所以给大也点。

/usr/ 10G 因为要安装软件，还有下载的软件，我没有装GUI 所以只分了10G我认为足够了。

/var 3G这个目录存放的东西比较多，如日志、邮件的临时目录，如果空间不够amavisd-new 无法解开邮件进行杀毒。

 %df -h  Filesystem   Size    Used    Avail   Capacity   Mounted on  /dev/ad0s1a   1.9G   481M   1.3G    26%       /
  devfs         1.0K    1.0K    0B      100%   /dev
  /dev/ad0s1g    92G    353M    84G    0%      /home/data
  /dev/ad0s1e    989M    224K    910M    0%    /tmp
  /dev/ad0s1f    9.7G    1.8G    7.1G    20%    /usr
  /dev/ad0s1d     2.9G   105M    2.6G     4%    /var

以上方案不是最好的，咸鱼白菜各有所好。

B、安装基本系统

对于系统的安装，我选择了minimal(最小系统)和ports ,因为有些没必要的包就不装，减少系统体积，另外作为一台服务器，我从来不装GUI 。

下载BSD时，只需要下载DISK 1 就行了，缺少的软件包可以通过网络安装。

C、配置系统

如果你在安装后期没有配置系统，在系统启动完成后以root的身份登陆系统，运行sysinstall 进行设置，或通过ee编辑器编辑/etc/rc.conf文件，在这里提醒各位，一会大多数服务都需要在/etc/rc.conf加入启动内容才能正常启动。

设置好固定IP，或通过DHCP 自动分配置机器IP。使用SSH 客户端进行管理服务器将会为你的工作提供方便。

使用SSH 要注意：

a、不能用root直接登陆，需要添加一个新用户，指定到wheel 组,用此用户登陆后用使用 su - 提升到管理员。

b、以我的SecureCRT 为例,Session options ->Authentication ->Primary 选择keyboard Interactive

c、如果你要使用像LINUX 一样的彩色显示，需要把 Emulation -> Terminal ->Xterm 选中ANSI Color 并在/etc/csh.cshrc加入

setenv LSCOLORS ExGxFxdxCxegedabagExEx setenv CLICOLOR yes
set autolist

然后执行

sed -i.bak -E s/set\ prompt/#set\ prompt/g /root/.cshrc

退出重新登陆即可看到彩色目录了。

D、更新软件包

采用Freebsd 最好的地方就是安装软件方便，还可以装到最新的软件包，这就是强大的posts 系统。如果你的系统在安装时没有选择posts ,具休如何操作看BSD 的handbook.

CVSUP 的站点很多，你可以选择离你最快的站点去更新posts ，具体查看 freebsd.org /freebsdchina.org.cn

在使用cvsup之前你必须连接到互联网，并需要安装cvsup 这个软件

假如你的服务器在内网里，并通过DMZ 进行IP映射，可以参考下面设置：

sshd_enable="YES"fsck_y_enable="YES"hostname="mail.extmail.org"ifconfig_rl0="inet 192.168.1.1 netmask 255.255.255.0"  defaultrouter="192.168.1.1"

如果你使用的是ADSL 拔号

a、修改/etc/ppp/ppp.conf

default:set log Phase tun command # you can add more detailed logging if you wishset ifaddr 10.0.0.1/0 10.0.0.2/0 adsl:  set device PPPoE:vr0 # 将vr0 改为你拔号的网卡  set authname 你的ADSL 帐号   set authkey 你的ADSL密码  set dial  set login  add default HISADDR

b、/etc/rc.conf 内容

inetd_enable="YES"sshd_enable="YES"fsck_y_enable="YES"hostname="mail.extmail.org"ifconfig_rl0="inet 192.168.1.1 netmask 255.255.255.0" ppp_enable="YES" #YES or NOppp_mode="ddial" #"auto", "ddial", "direct" or "dedicated".ppp_nat="YES" # if you want to enable nat for your local network, otherwise NOppp_profile="adsl" #/etc/ppp/ppp.conf

c、安装cvsup-without-gui

 %cd /usr/ports/net/cvsup-without-gui/ %make install clean

d、更新ports
安装完cvsup软件后，对ports 进行更新

%/usr/local/bin/cvsup -gL 2 -h cvsup4.freebsdchina.org /usr/share/examples/cvsup/ports-supfile

其实FreeBSD 一点也不难，我没有说错吧！

三、安装数据库 MySQL

MySQL 版本很多，大家可以据自己需要自行安装。

%cd /usr/ports/databases/mysql41-server/%make install clean

在/etc/rc.conf 加入

mysql_enable="YES"

复制配置文件（非必需）

cp /usr/local/share/mysql/my-small.cnf /usr/local/etc/my.cnf

在此说明：

1、如果不在/etc/rc.conf 加入以上内容，手工是无法启动MySQL的。
2、如果你想知道这个软件应该在/etc/rc.conf加入什么内容，打开/usr/local/etc/rc.d 目录，找到此软件的启动脚本。然后打开文件，如果有详细的说明。

%/usr/local/etc/rc.d/mysql-server.sh start Starting mysql.

如何去检查一个服务是否正常启动：1、通过ps查看进程，2、检查所打开的端口。

%ps aux|grep mysqlmysql 94899  0.2  0.5  1644  1240  p0  S     3:52PM   0:00.07 /bin/sh /usr/local/bin/mysqld_safe --mysql 94919  0.0 10.8 55564 27428  p0  S     3:52PM   0:01.54 /usr/local/libexec/mysqld --defaults-%%netstat -an|grep 3306tcp4       0      0  *.3306                 *.*                    LISTEN

MySQL安装时，服务器的密码为空，建议你装好系统后，第一时间去更改密码。

%/usr/local/bin/mysqladmin -u root -p password 你的新密码 Enter password:

如果你服务器只供本站内部使用建议在 my.cnf 里加入下面内容,以增加服务器的安全性。

[mysqld]bind_address=127.0.0.1

四、安装Apache

1、安装apache server

作为网络的今天apache web服务器已经是街知港闻了。

%cd /usr/ports/www/apache22/%make install clean

在/etc/rc.conf 中加入：

apache22_enable="YES"

如果启动时出现httpd: Could not reliably determine the server's fully qualified domain name, using mail.sharesky.cn for ServerName 的错误，在/usr/local/etc/apache22/httpd.conf 约第144行的位置加入下面的内容。

ServerName mail.extmail.org

启动apahce

%/usr/local/etc/rc.d/apache22.sh startPerforming sanity check on apache22 configuration:Syntax OKStarting apache22.

2、安装PHP

%cd /usr/ports/www/mod_php4/%make install clean

                  Options for mod_php4 4.4.2_1,1                    x                 x lqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqk x                 x x         [ ] DEBUG      Enable debug                            x x                 x x         [X] MULTIBYTE  Enable zend multibyte support           x x                 x x         [ ] IPV6       Enable ipv6 support                     x x                 x x         [X] OPENSSL    Build static OpenSSL extension

在/usr/local/etc/apache22/httpd.conf 里加入

AddType application/x-httpd-php .phpAddType application/x-httpd-php-source .phps

加入目录索引 index.php，约在httpd.conf 的212行

 DirectoryIndex index.html index.php

restart或reload Apache 使之生效

%/usr/local/etc/rc.d/apache22.sh reloadPerforming sanity check on apache22 configuration:Syntax OKPerforming a graceful restart

3、安装PHP 扩展

%cd /usr/ports/lang/php4-extensions/%make install clean

在这里建议大家，如果没有必要尽量不要安装GD库免得浪费时间，大家可据自己需要选择安装模块

               lqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqk               x                 Options for php4-extensions 1.0                    x                 x

4、安装phpmyadmin 管理数据库

为了去除无聊的安装过程，这里选择手工安装，先下载软件包，然后解压，再复制到/usr/local/www/apache22/data 下面

%cd /usr/ports/databases/phpmyadmin/%make fetch%cd /usr/ports/distfile%tar jxvf phpMyAdmin-2.7.0-pl2.tar.bz2%cp -r /usr/ports/distfiles/phpMyAdmin-2.7.0-pl2 /usr/local/www/apache22/data/phpmyadmin

大家注意，可能你下载的版本与我下载的不一样，不能照搬。

设置phpmyadmin

%cd /usr/local/www/apache22/data/phpmyadmin/%ee config.default.php

将$cfg['Servers'][$i]['auth_type'] = 'config'; 改为

$cfg['Servers'][$i]['auth_type']     = 'http';

打开http://ip/phpmyadmin 就可以管理你的mysql 数据库了

5、安装extman

extman 是extmail用户后台管理系统,官方网站为www.extmail.org 下载解压

%tar zxvf extman-13-20060102.tar.gz%cd extman-0.13-20060102/docs%mysql -u root -p <extmail.sql Enter password: %mysql -u root -p <init.sql Enter password:

extmail.sql添加了两个MySQL用户

1、只读用户：extmail 密码：extmail

2、读/写用户：webman 密码：webman

init.sql 里，对extmail数据库添加了下面的记录

a、添加了一个别名记录 support@extmail.org ->test@extmail.org

b、增加了 extmail.org 域

c、增加了test@extmail.org的邮箱密码为test。

d、增加了extman 的管理员root@extmail.org 密码为extmail

五、安装邮件系统

安装下面三个软件要注意先后顺序

1、安装 Courier-IMAP

%cd /usr/ports/mail/courier-imap/%make install clean

选择openssl、MySQL

在/etc/rc.conf 加入

courier_authdaemond_enable="YES"courier_imap_pop3d_enable="YES"courier_imap_imapd_enable="YES"

修改authdaemond的权限

%/usr/local/etc/rc.d/courier-authdaemond.sh start%chmod -R  +x /var/run/authdaemond/

authdaemond 启动完成后，检查/var/run/authdaemond 下面是否产生socket 文件，因为认证时是通过这个文件读取密码的。

设置/usr/local/etc/authlib/authdaemonrc

%mv authdaemonrc authdaemonrc.bakee authdaemonrc

在authdaemonrc 加入下面的内容

authmodulelist="authmysql"authmodulelistorig="authmysql"version="authdaemond.mysql"daemons=5                             authdaemover=/var/run/authdaemond     subsystem=mail                        DEBUG_LOGIN=2                         DEFAULTOPTIONS="wbnodsn=1"

上面DEBUG_LOGIN=2 是为了调试方便，等系统完全测试完成，可改为 0，即不显示调试信息。

设置/usr/local/etc/authlib/authmysqlrc

%mv authmysqlrc authmysqlrc.bakee authmysqlrc

加入下面的内容

MYSQL_SERVER    localhostMYSQL_USERNAME  extmailMYSQL_PASSWORD  extmailMYSQL_PORT      0MYSQL_OPT       0MYSQL_DATABASE  extmailMYSQL_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)'

大家要注意，我的邮件保存的目录是/home/data/domains ，你可以跟据你的需要改为自己的目录。

用户名和密码是extmail 这个具体需要看extman 软件包中的docs 目录中的extmail.sql，很多人无法通上发信认证，很可能以上面两个文件配置有关。

创建pop3/imap 的配置文件

%cp pop3d.cnf.dist pop3d.cnf%cp imapd.cnf.dist imapd.cnf

修改/usr/local/etc/courier-imap/pop3d (不修改也行)

POP3AUTH="LOGIN CRAM-MD5 CRAM-SHA1"

修改/usr/local/etc/courier-imap/imapd(不修改也行)

IMAP_CAPABILITY="IMAP4rev1 CHILDREN NAMESPACE THREAD=ORDEREDSUBJECT THREAD=REFERENCES SORT QUOTA"

2、安装 Cyrus-SASL2

%cd /usr/ports/security/cyrus-sasl2%make install WITH_AUTHDAEMON=yes

创建 /usr/local/lib/sasl2/smtpd.conf 加入下面的内容

pwcheck_method:authdaemondlog_level:3mech_list:PLAIN LOGINauthdaemond_path:/var/run/authdaemond/socket

3、安装Postfix

%cd /usr/ports/mail/postfix%make install clean

选择SASL2 、TLS、MySQL、VDA ，安装过程中有两个提问，直接按回车，使用系统默认的回答。

%echo postfix: root >> /etc/aliases%/usr/local/bin/newaliases%ln -s /usr/local/sbin/sendmail /usr/sbin/sendmail

如果出现ln: /usr/sbin/sendmail: File exists 提示，把/usr/sbin/sendmail改名再链接。

设置postfix 随系统启动

postfix_enable="YES"                  sendmail_enable="NO"                  sendmail_submit_enable="NO"           sendmail_outbound_enable="NO"sendmail_msp_queue_enable="NO"

创建/etc/periodic.conf 加入下面的内容

daily_clean_hoststat_enable="NO"daily_status_mail_rejects_enable="NO"daily_status_include_submit_mailq="NO"daily_submit_queuerun="NO"

配置/usr/local/etc/postfix/main.cf ,在你安装时，只需要修改####BASE#### 部分即可

%mv main.cf main.cf.bak

这个配置文件已经加入了maildrop的支持

###################BASE##################myhostname=mail.extmail.org   #机器的名字mydomain = extmail.org		#你的域名mydestination = $myhostnamelocal_recipient_maps = command_directory = /usr/local/sbin#local_transport = virtualsmtpd_banner = extmail.org ESMTP Mail Systemmessage_size_limit = 14680064		#邮件大小#mailbox_size_limit = 512000000#################MySQL################virtual_alias_maps =mysql:/usr/local/etc/postfix/mysql_virtual_alias_maps.cf#virtual_gid_maps = static:125#virtual_gid_maps = static:1000virtual_mailbox_base = /home/data/domains  #邮件保存的目录virtual_mailbox_domains = mysql:/usr/local/etc/postfix/mysql_virtual_domains_maps.cf#virtual_mailbox_limit = 512000000virtual_mailbox_maps = mysql:/usr/local/etc/postfix/mysql_virtual_mailbox_maps.cf#virtual_minimum_uid = 125#virtual_minimum_uid = 1000#virtual_transport = virtualvirtual_transport = maildrop:maildrop_destination_recipient_limit = 1 #virtual_uid_maps = static:125#virtual_uid_maps = static:1000################Quota################virtual_create_maildirsize = yesvirtual_mailbox_extended = yesvirtual_mailbox_limit_maps = mysql:/usr/local/etc/postfix/mysql_virtual_mailbox_limit_maps.cfvirtual_mailbox_limit_override = yesvirtual_maildir_limit_message = Sorry,the user's Maildir has overdrawn his diskspace quota ,please tray again later.virtual_overquota_bounce = yes##############SASL####################smtpd_sasl_auth_enable = yessmtpd_sasl2_auth_enable = yessmtpd_sasl_security_options = noanonymousbroken_sasl_auth_clients = yessmtpd_recipient_restrictions =  permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination, reject_unauth_pipelining, reject_invalid_hostname, reject_rbl_client cbl.anti-spam.org.cn			#CBL 服务器 具体请看anti-spam.org.cn#注意上面几行前面是有空格的。readme_directory = nosample_directory = /usr/local/etc/postfixsendmail_path = /usr/local/sbin/sendmailhtml_directory = nosetgid_group = maildropmanpage_directory = /usr/local/mandaemon_directory = /usr/local/libexec/postfixnewaliases_path = /usr/local/bin/newaliasesmailq_path = /usr/local/bin/mailqqueue_directory = /var/spool/postfixmail_owner = postfix

以下四个文件在extman 软件包Docs 目录里，使用时，直接复制到/usr/local/etc/postfix 目录即可。

mysql_virtual_alias_maps.cf

user = extmailpassword = extmailhosts = localhostdbname = extmailtable = aliasselect_field = gotowhere_field = addressadditional_conditions = AND active = '1'

mysql_virtual_domains_maps.cf

user = extmailpassword = extmailhosts = localhostdbname = extmailtable = domainselect_field = descriptionwhere_field = domainadditional_conditions = AND active = '1'

mysql_virtual_mailbox_maps.cf

user = extmailpassword = extmailhosts = localhostdbname = extmailtable = mailboxselect_field = maildirwhere_field = usernameadditional_conditions = AND active = '1'

mysql_virtual_mailbox_limit_maps.cf

user = extmailpassword = extmailhosts = localhostdbname = extmailtable = mailboxselect_field = quotawhere_field = usernameadditional_conditions = AND active = '1'

至此postfix 基本设置完成，但还不能收发邮件。

4、安装maildrop

我们在设置邮件服务器时MTA 部分还是使用posfix 本身的帐户进行处理邮件，由于maildrop 不能和postfix 与同一用户身份处理邮件，所以我们新开一个用户用户maildrop 处理。

添加vgroup

pw groupadd vgroup -g 1000

添加vuser

%pw useradd vuser -g 1000 -u 1000 -s /sbin/nologin -d /sbin/nologin -c "virtual mail user"

安装maildrop,记得要把WITH_AUTHLIB=yes 加上

%cd /usr/ports/mail/maildrop%make install WITH_AUTHLIB=yes

选择AUTH_MYSQL

        lqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqk               x                    Options for maildrop 2.0.1                      x                 x lqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqk x                 x x            [ ] AUTH_LDAP    LDAP support                       x x                 x x            [X] AUTH_MYSQL   MySQL support                      x x                 x x            [ ] AUTH_PGSQL   PostgreSQL support                 x x                 x x            [ ] AUTH_USERDB  Userdb support                     x x                 x x            [ ] AUTH_VCHKPW  Vpopmail/vchkpw support            x x

修改/usr/local/etc/postfix/master.cf ,把maildrop 原先已有的记录注译（即删除旧记录），加上下面的内容

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

设置邮件存储目录

%mkdir -p /home/data/domains/extmail.org/test%/usr/local/bin/maildirmake /home/data/domains/extmail.org/test/Maildir%chown -R 1000:1000 domains/

至此，我们的邮件系统基础部分已经安装完成了。重启系统，开始进行测试。

六、测试系统

1、测试maildrop 是否正常

建议进入系统后去检查/etc/rc.conf 中的服务是否正常。

注意邮件系统用户名格式是：user@domain.ltd ，是支持多域的，和平时用的有点不一样。

用SecureCRT 新开二个窗口，其中一个用于输入命令，一个查看maillog

%tail -f /var/log/maillog

观察下面的操作,证明maildrop 已投递正常

%echo "test" | maildrop -V 10 -d test@extmail.orgmaildrop: authlib: groupid=1000maildrop: authlib: userid=1000maildrop: authlib: logname=test@extmail.org, home=/home/data/domains/extmail.org/test, mail=/home/data/domains/extmail.org/test/Maildir/maildrop: Changing to /home/data/domains/extmail.org/testMessage start at 0 bytes, envelope sender=test@extmail.orgmaildrop: Attempting .mailfilterWARN: quota string '5242880' not parseablemaildrop: Delivery complete.

maillog 将会有如下显示

Mar 10 14:39:58 mail authdaemond: Authenticated: sysusername=, sysuserid=1000, sysgroupid=1000, homedir=/home/data/domains/extmail.org/test, address=test@extmail.org, fullname=Test user, maildir=/home/data/domains/extmail.org/test/Maildir/, quota=5242880, options=Mar 10 14:39:58 mail authdaemond: Authenticated: clearpasswd=, passwd={crypt}uywiuN.XggXXc

2、测试postfix

由于在发信认证时使用的是BASE64 编码，所以要把用户名和密码转BASE64 格式，在此前需要安装 p5-MIME-BASE64

%cd /usr/ports/converters/p5-MIME-Base64/%make install

测试用户test@extmail.org 密码 test

%perl -MMIME::Base64 -e 'print encode_base64("test\@extmail.org");'                   dGVzdEBleHRtYWlsLm9yZw==%perl -MMIME::Base64 -e 'print encode_base64("test");'      dGVzdA==

看下面的测试过程

%telnet localhost 25Trying ::1...telnet: connect to address ::1: Connection refusedTrying 127.0.0.1...Connected to localhost.Escape character is '^]'.220 sharesky.cn ESMTP Mail Systemehlo test.com250-mail.extmail.org250-PIPELINING250-SIZE 14680064250-VRFY250-ETRN250-AUTH LOGIN PLAIN250-AUTH=LOGIN PLAIN250 8BITMIMEauth login334 VXNlcm5hbWU6dGVzdEBleHRtYWlsLm9yZw==334 UGFzc3dvcmQ6dGVzdA==235 Authentication successfulmail from:<test@test.com>250 Okrcpt to:<test@extmail.org>250 Okdata354 End data with .this is a test..250 Ok: queued as 23CEE5C38quit221 ByeConnection closed by foreign host.

下面是系统所产生的maillog

Mar 10 14:47:45 mail postfix/smtpd[1090]: connect from localhost[127.0.0.1]Mar 10 14:47:57 mail authdaemond: Authenticated: sysusername=<null>, sysuserid=1000, sysgroupid=1000, homedir=/home/data/domains/extmail.org/test, address=test@extmail.org, fullname=Test user, maildir=/home/data/domains/extmail.org/test/Maildir/, quota=5242880, options=Mar 10 14:47:57 mail authdaemond: Authenticated: clearpasswd=test, passwd={crypt}uywiuN.XggXXcMar 10 14:48:13 mail postfix/smtpd[1090]: 23CEE5C38: client=localhost[127.0.0.1], sasl_method=login, sasl_username=test@extmail.orgMar 10 14:48:18 mail postfix/cleanup[1135]: 23CEE5C38: message-id=<20060310144813.23CEE5C38@mail.extmail.org>Mar 10 14:48:18 mail postfix/qmgr[669]: 23CEE5C38: from=<test@test.com>, size=341, nrcpt=1 (queue active)Mar 10 14:48:19 mail authdaemond: Authenticated: sysusername=, sysuserid=1000, sysgroupid=1000, homedir=/home/data/domains/extmail.org/test, address=test@extmail.org, fullname=Test user, maildir=/home/data/domains/extmail.org/test/Maildir/, quota=5242880, options=Mar 10 14:48:19 mail authdaemond: Authenticated: clearpasswd=, passwd={crypt}uywiuN.XggXXcMar 10 14:48:19 mail postfix/pipe[1136]: 23CEE5C38: to=<test@extmail.org>, relay=maildrop, delay=14, status=sent (extmail.org)Mar 10 14:48:19 mail postfix/qmgr[669]: 23CEE5C38: removedMar 10 14:48:20 mail postfix/smtpd[1090]: disconnect from localhost[127.0.0.1]

所产生的maillog

Mar 10 16:17:56 mail authdaemond: Authenticated: sysusername=, sysuserid=1000, sysgroupid=1000, homedir=/home/data/domains/extmail.org/test, address=test@extmail.org, fullname=Test user, maildir=/home/data/domains/extmail.org/test/Maildir/, quota=5242880, options=Mar 10 16:17:56 mail authdaemond: Authenticated: clearpasswd=test, passwd={crypt}uywiuN.XggXXcMar 10 16:17:57 mail pop3d: LOGIN, user=test@extmail.org, ip=[127.0.0.1]Mar 10 16:18:15 mail pop3d: LOGOUT, user=test@extmail.org, ip=[127.0.0.1], top=0, retr=397, time=18

至此，我们已经成功安装了一个邮件系统，下面我们再去增加内容过滤和反垃圾邮件部分还成web部分，成功已经离我们不远了，鼓起干劲，冲啊~~！~！~！~~~RUSH...

七、安装反垃圾邮件

1、安装amavisd-new

内容过滤我们采用了amavisd-new ，主要考滤到amavsid-new 配置方便，当然你也可以使用mailscanner，还是那一句，咸鱼白菜，各有所好。

%cd /usr/ports/security/amavisd-new/%make install clean

只选择MYSQL

在安装Amavisd-new 时，系统会自动把Spamassassin 装上去

               lqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqk               x             Options for p5-Mail-SpamAssassin 3.1.0_6               x                 x lqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqk x                 x x   [X] AS_ROOT        Run spamd as root (recommended)           x x                 x x   [ ] DOMAINKEYS     DomainKeys support                        x x                 x x   [X] SSL            Build with SSL support for spamd/spamc    x x                 x x   [X] MYSQL          Add MySQL support                         x x                 x x   [ ] PGSQL          Add PostreSQL support                     x x                 x x   [ ] RAZOR          Add Vipul's Razor support                 x x                 x x   [ ] SPF_QUERY      Add SPF query support                     x x                 x x   [ ] RELAY_COUNTRY  Relay country support                     x x                 x x   [X] TOOLS          Install SpamAssassin tools                x x

在/etc/rc.conf 加入下面的内容

amavisd_enable="YES"spamd_enable="YES"

修改 /usr/local/etc/amavisd.conf

$mydomain = 'extmail.org';

垃圾邮件病毒通知

$virus_admin               = "postmaster\@$mydomain";  # notifications recip.$mailfrom_notify_admin     = "postmaster\@$mydomain";  # notifications sender$mailfrom_notify_recip     = "postmaster\@$mydomain";  # notifications sender$mailfrom_notify_spamadmin = "postmaster\@$mydomain"; # notifications sender$mailfrom_to_quarantine = ''; # null return path; uses original sender if undef

去除对附件的转换

$banned_filename_re = new_RE(#把中间的内容全部加上#);

加入对Clamav 的支持

# ### http://www.clamav.net/ ['ClamAV-clamd',   \&ask_daemon, ["CONTSCAN {}\n", "/var/run/clamav/clamd"],   qr/\bOK$/, qr/\bFOUND$/,   qr/^.*?: (?!Infected Archive)(.*) FOUND$/ ],

在/usr/local/etc/postfix/main.cf 加入

content_filter = smtp-amavis:[127.0.0.1]:10024

在/usr/local/etc/postfix/master.cf 加入

smtp-amavis unix -   -   n     -       2  smtp         -o smtp_data_done_timeout=1200         -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_client_restrictions=         -o smtpd_helo_restrictions=         -o smtpd_sender_restrictions=         -o smtpd_recipient_restrictions=permit_mynetworks,reject        -o mynetworks=127.0.0.0/8

重启postfix

%/usr/local/etc/rc.d/postfix.sh restartpostfix/postfix-script: stopping the Postfix mail systempostfix/postfix-script: starting the Postfix mail system

对于Spamassassin 配置文件/usr/local/etc/mail/spamassassin/local.cf 请参考

http://spamassassin.apache.org/

配置工具

http://www.yrex.com/spam/spamconfig.php

调试amavisd-new

%su vscan$ /etc/sbin/amavisd debug

如果没有出现任何错误，证明你的amavisd-new 正常。

2、安装Clamav

clamav 用于邮件杀毒

%cd /usr/ports/security/clamav%make install clean

可以什么都不选，直接回车

clamav_clamd_enable="YES"clamav_freshclam_enable="YES"

修改/usr/local/etc/clamd.conf 让其以vscan 身份运行(约145行)

#User clamavUser vscan

修改/usr/local/etc/freshclam.conf

#DatabaseOwner clamavDatabaseOwner vscan

修目录权限

%chown -R vscan:vscan /var/log/clamav%chown -R vscan:vscan /var/run/clamav%chown -R vscan:vscan /var/db/clamav

启动clamav 与自动更新

%/usr/local/etc/rc.d/clamav-clamd.sh start%/usr/local/etc/rc.d/clamav-freshclam.sh start

3、测试

%telnet localhost 25Trying ::1...telnet: connect to address ::1: Connection refusedTrying 127.0.0.1...Connected to localhost.mold.com.cn.Escape character is '^]'.220 extmail.org ESMTP Mail Systemehlo test.com250-mail.mold.com.cn250-PIPELINING250-SIZE 14680064250-VRFY250-ETRN250-AUTH LOGIN PLAIN250-AUTH=LOGIN PLAIN250 8BITMIMEmail from:<test@test.com>250 Okrcpt to:<test@extmail.org>250 Okdata354 End data with .X5O!P%@AP[4\PZX54(P^)7CC)7}$EICAR-STANDARD-ANTIVIRUS-TEST-FILE!$H+H*.250 Ok: queued as F19692E084quit221 ByeConnection closed by foreign host.

所产生的maillog

观看红色的地方，病毒已经找到，并隔离了。随之这封邮件被系统删除。

至此空容过滤杀毒部分已经完，这个时候应该休息一下，喝杯水，接下来完成最后的工作。

八、安装extmail /extman

1、设置apache 的运行身份

修改/usr/local/etc/apache22/httpd.conf

#User www#Group wwwUser vuserGroup vgroup

在httpd.conf 加入下面的内容

Alias /extman/cgi/ /usr/local/www/apache22/cgi-bin/extman/cgi/Alias /extman /usr/local/www/apache22/cgi-bin/extman/html/<Location "/extman/cgi">SetHandler cgi-scriptOptions +ExecCGIAllowOverride All</Location># config for ExtMail               Alias /extmail/cgi/ /usr/local/www/apache22/cgi-bin/extmail/cgi/Alias /extmail /usr/local/www/apache22/cgi-bin/extmail/html/<Location "/extmail/cgi">SetHandler cgi-scriptOptions +ExecCGIAllowOverride All</Location>

重启apahce

%/usr/local/etc/rc.d/apache22.sh restartPerforming sanity check on apache22 configuration:Syntax OKStopping apache22.Waiting for PIDS: 461.Performing sanity check on apache22 configuration:Syntax OKStarting apache22.

2、安装extmail

从extmail官方网站:www.extmail.org 下载最新版式

tar zxvf extmail-23-20060219.tar.gz %cp -r  extmail-0.23-20060219/ /usr/local/www/apache22/cgi-bin/extmail

创建配置文件

%cd /usr/local/www/apache22/cgi-bin/extmail/%cp webmail.cf.default webmail.cf

修改配置文件,我只把需要修改的地方贴出来

# sys_config, the config file and webmail programe rootSYS_CONFIG = /usr/local/www/apache22/cgi-bin/extmail/# sys_langdir, the i18n dirSYS_LANGDIR = /usr/local/www/apache22/cgi-bin/extmail/lang# sys_templdir, the template dirSYS_TEMPLDIR = /usr/local/www/apache22/cgi-bin/extmail/html# sys_netdisk_on, default is offSYS_NETDISK_ON = 1 # maildir_base, the base dir of user maildir, use absolute path# if not set.SYS_MAILDIR_BASE = /home/data/domains# if mysql, all relate paramters should prefix as SYS_MYSQLSYS_MYSQL_USER = extmail   SYS_MYSQL_PASS = extmail   SYS_MYSQL_DB = extmail     SYS_MYSQL_HOST = localhostSYS_MYSQL_SOCKET = /tmp/mysql.sock

打开你的浏览器，输入http://ip/extmail 即可看到登陆窗口

用户名：test

密码:test

域名：extmail.org

3、安装extman

从extmail 官方网站下载软件包，解压复制到/usr/local/www/apache22/cgi-bin目录。

%cd /usr/local/www/apache22/cgi-bin/extman/

编辑 webman.cf

# sys_config, the config file and webman programe rootSYS_CONFIG = /usr/local/www/apache22/cgi-bin/extman/# sys_langdir, the i18n dirSYS_LANGDIR = /usr/local/www/apache22/cgi-bin/extman/lang# sys_templdir, the template dirSYS_TEMPLDIR = /usr/local/www/apache22/cgi-bin/extman/html# maildir_base, the base dir of user maildir, use absolute path# if not set. SYS_MAILDIR_BASE = /home/data/domains# if mysql, all relate paramters should prefix as SYS_MYSQLSYS_MYSQL_USER = webmanSYS_MYSQL_PASS = webmanSYS_MYSQL_DB = extmailSYS_MYSQL_HOST = localhostSYS_MYSQL_SOCKET = /tmp/mysql.sock

创建/tmp/extman

%mkdir /tmp/extman%chmod 777 /tmp/extman/

创建软件包的链接

%cd extman/libs/Ext/%./buildlink.sh build /usr/local/www/apache22/cgi-bin/extmail/libs/Ext/

打开浏览器输入http://ip/extman

用户名：root@extmail.org 密码：extmail

系统配置文件下载

rc.conf 内容

mysql_enable="YES"apache22_enable="YES"postfix_enable="YES"sendmail_enable="NO"sendmail_submit_enable="NO"sendmail_outbound_enable="NO"sendmail_msp_queue_enable="NO"courier_authdaemond_enable="YES"courier_imap_pop3d_enable="YES"courier_imap_imapd_enable="YES"amavisd_enable="YES"spamd_enable="YES"clamav_clamd_enable="YES"clamav_freshclam_enable="YES"

由于水平有限，时间急促，文档中难免有错漏，如果你发现错误，或有更好的建议请告诉我，本人一定尽力做到最好。

感谢你的阅读！
