FreeBSD系统上部署ISP级extmail-postfix邮件服务器

  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 221.4.66.66

  Server: ns2.cnc-gd.net

  Address: 221.4.66.66

  DNS request timed out.

  timeout was 2 seconds.

  Non-authoritative answer:

  extmail.org MX preference = 20, mail exchanger = mx.extmail.org

  extmail.org nameserver = ns2.xinnetdns.com

  extmail.org nameserver = ns.xinnet.cn

  extmail.org nameserver = ns.xinnetdns.com

  extmail.org nameserver = ns2.xinnet.cn

  mx.extmail.org internet address = 210.21.119.139

  ns.xinnet.cn internet address = 210.51.171.209

  ns.xinnetdns.com internet address = 210.51.170.66

  ns2.xinnet.cn internet address = 210.51.170.67

  ns2.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


  用户可以跟据自己的需要进行分区。

  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 wish

  set 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 NO

  ppp_mode="ddial" #"auto", "ddial", "direct" or "dedicated".

  ppp_nat="YES" # if you want to enable nat for your local network, otherwise NO

  ppp_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


  三、安装数据库 MySQL

  MySQL 版本很多,大家可以据自己需要自行选择喜欢的版本安装。

  %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 mysql

  mysql 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 3306

  tcp4 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 start

  Performing sanity check on apache22 configuration:

  Syntax OK

  Starting apache22.2、安装PHP%cd /usr/ports/lang/php4/

  %make install cleanOptions 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 .php

  AddType 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 reload

  Performing sanity check on apache22 configuration:

  Syntax OK

  Performing 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

  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 .sql>

  Enter password:

  %mysql -u root -p .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.bak

  ee 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.bak

  ee authmysqlrc


  加入下面的内容

  MYSQL_SERVER localhost

  MYSQL_USERNAME extmail

  MYSQL_PASSWORD extmail

  MYSQL_PORT 0

  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)'

  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:authdaemond

  log_level:3

  mech_list:PLAIN LOGIN

  authdaemond_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##################

  readme_directory = no

  sample_directory = /usr/local/etc/postfix

  sendmail_path = /usr/local/sbin/sendmail

  html_directory = no

  setgid_group = maildrop

  manpage_directory = /usr/local/man

  daemon_directory = /usr/local/libexec/postfix

  newaliases_path = /usr/local/bin/newaliases

  mailq_path = /usr/local/bin/mailq

  queue_directory = /var/spool/postfix

  mail_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 = extmail

  password = extmail

  hosts = localhost

  dbname = extmail

  table = alias

  select_field = goto

  where_field = address

  additional_conditions = AND active = '1'


  mysql_virtual_domains_maps.cf

  user = extmail

  password = extmail

  hosts = localhost

  dbname = extmail

  table = domain

  select_field = description

  where_field = domain

  additional_conditions = AND active = '1'


  mysql_virtual_mailbox_maps.cf

  user = extmail

  password = extmail

  hosts = localhost

  dbname = extmail

  table = mailbox

  select_field = maildir

  where_field = username

  additional_conditions = AND active = '1'


  mysql_virtual_mailbox_limit_maps.cf

  user = extmail

  password = extmail

  hosts = localhost

  dbname = extmail

  table = mailbox

  select_field = quota

  where_field = username

  additional_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 /home/data/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.org

  maildrop: authlib: groupid=1000

  maildrop: authlib: userid=1000

  maildrop: 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/test

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

  maildrop: Attempting .mailfilter

  WARN: quota string '5242880' not parseable

  maildrop: 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

  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。


  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。

  %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
