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%26amp;q=IBM%E6%99%BA%E8%83%BD%E8%AF%8D%E5%85%B8%26amp;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。
点击查看大图
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 yesset 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 *.* LISTENMySQL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.phprestart或reload Apache 使之生效
%/usr/local/etc/rc.d/apache22.sh reloadPerforming sanity check on apache22 configuration:Syntax OKPerforming a graceful restart3、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 lqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqk x x x [ ] BCMATH bc style precision math functions x x x x [X] BZ2 bzip2 library support x x x x [ ] CALENDAR calendar conversion support x x x x [ ] CRACK crack support x x x x [X] CTYPE ctype functions x x x x [X] CURL CURL support x x x x [ ] DBA dba support x x x x [ ] DBASE dBase library support x x x x [ ] DBX dbx support x x x x [ ] DIO Direct I/O support x x x x [ ] DOMXML DOM support x x x x [ ] EXIF EXIF support x x x x [ ] FILEINFO fileinfo support x x x x [ ] FILEPRO filePro support x x x x [ ] FRIBIDI FriBidi support x x [X] FTP FTP support x x x x [ ] GD GD library support x x x x [X] GETTEXT gettext library support x x x x [ ] GMP GNU MP support x x x x [X] ICONV iconv support x x x x [ ] IMAGICK ImageMagick support x x x x [X] IMAP IMAP support x x x x [ ] INTERBASE Interbase 6 database support (Firebird) x x x x [ ] LDAP OpenLDAP support x x x x [X] MBSTRING multibyte string support x x x x [ ] MCAL Modular Calendar Access Library support x x x x [X] MCRYPT Encryption support x x x x [ ] MCVE MCVE support x x x x [ ] MHASH Crypto-hashing support x x x x [ ] MING ming shockwave flash support x x x x [ ] MNOGOSEARCH mnoGoSearch support x x x x [ ] MSSQL MS-SQL database support x x x x [X] MYSQL MySQL database support x x x x [ ] NCURSES ncurses support (CLI only) x x x x [ ] ODBC unixODBC support x x x x [X] OPENSSL OpenSSL support x x x x [ ] ORACLE Oracle support x x x x [X] OVERLOAD user-space object overloading support x x x x [ ] PANDA panda support x x x x [ ] PCNTL pcntl support (CLI only) x x x x [X] PCRE Perl Compatible Regular Expression support x x x x [ ] PDF PDFlib support (implies GD) x x x x [ ] PFPRO PayFlow Pro support x x x x [ ] PGSQL PostgreSQL database support x x x x [X] POSIX POSIX-like functions x x x x [ ] PSPELL pspell support x x x x [ ] READLINE readline support (CLI only) x x x x [ ] RECODE recode support x x x x [X] SESSION session support x x x x [ ] SHMOP shmop support x x x x [ ] SNMP SNMP support x x x x [ ] SOCKETS sockets support x x x x [ ] SYBASE_CT Sybase database support x x x x [ ] SYSVMSG System V message support x x x x [ ] SYSVSEM System V semaphore support x x x x [ ] SYSVSHM System V shared memory support x x x x [X] TOKENIZER tokenizer support x x x x [ ] WDDX WDDX support (implies XML) x x x x [X] XML XML support x x x x [ ] XMLRPC XMLRPC-EPI support x x x x [ ] XSLT XSLT Sablotron support x x x x [ ] YAZ YAZ support (ANSI/NISO Z39.50) x x x x [ ] YP YP/NIS support x x x x [ ] ZIP ZIP support x x x x [X] ZLIB ZLIB support 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添加了两个MySQL用户1、只读用户：extmail 密码：extmail2、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.orgb、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/socket3、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

'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

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

quota=5242880, options=Mar 10 14:39:58 mail authdaemond: Authenticated: clearpasswd=, passwd={crypt}uywiuN.XggXXc2、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

，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

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# ###

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

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Clamavclamav 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

localhost[127.0.0.1]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/SetHandler cgi-scriptOptions +ExecCGIAllowOverride All#
