FreeBSD5.2.1上建立功能完整的邮件服务器(POSTFIX)
<p>1．更新 ports<br /><br />
# cvsup -gL 2 -h cvsup.freebsdchina.org /usr/share/examples/cvsup/ports-supfile <br />
<br />
<br />
2. <a target="_blank" href="#" class="UBBWordLink">安装</a> openssl+apache <a target="_blank" href="#" class="UBBWordLink">服务</a>器 <br />
<br />
# cd /usr/ports/security/openssl<br />
# make install<br />
# make clean<br />
# cd /usr/ports/www/apache2<br />
# make install <br />
# make clean <br />
# vi /etc/rc.conf<br />
<br />
apache2_enable="YES"<br />
<br />
<br />
3. <a target="_blank" href="#" class="UBBWordLink">安装</a> openwebmail <br />
<br />
# cd /usr/ports/mail/openwebmail/ <br />
# make WITH_QUOTA=yes install<br />
# make clean <br />
<br />
<br />
4. <a target="_blank" href="#" class="UBBWordLink">安装</a> postfix ，在<a target="_blank" href="#" class="UBBWordLink">安装</a>过程中用yes回答提出的问题<br />
<br />
# cd /usr/ports/mail/postfix/ <br />
# make install<br />
# make clean <br />
<br />
# vi /etc/rc.conf<br />
<br />
为了能启动postfix加入： <br />
<br />
sendmail_enable="YES" <br />
sendmail_flags="-bd" <br />
sendmail_pidfile="/var/spool/postfix/pid/master.pid" <br />
sendmail_outbound_enable="NO" <br />
sendmail_submit_enable="NO" <br />
<br />
<br />
5. <a target="_blank" href="#" class="UBBWordLink">安装</a> vm-pop3d <br />
<br />
# cd /usr/ports/mail/vm-pop3d <br />
# make install <br />
# make clean <br />
<br />
<br />
6. 配置 postfix <br />
<br />
# vi /usr/local/etc/postfix/main.cf <br />
<br />
添加：<br />
<br />
myhostname = nero.3322.org<br />
mydomain = nero.3322.org<br />
virtual_alias_maps=hash:/usr/local/etc/postfix/virtual <br />
alias_maps=hash:/usr/local/etc/postfix/aliases <br />
default_privs=nobody <br />
allow_mail_to_commands = alias,forward,include <br />
allow_mail_to_files = alias,forward,include <br />
<br />
<br />
下面我加入一个 nero.3322.org 的虚拟域，并添加一个用户llzqq<br />
# vi /usr/local/etc/postfix/virtual <br />
<br />
添加： <br />
<br />
nero.3322.org anything //之间用<br />
llzqq@nero.3322.org llzqq.nero.3322.org //之间用 <br />
<br />
执行下面的命令，生成 virtual.db： <br />
<br />
# cd /usr/local/etc/postfix/<br />
# postmap virtual<br />
<br />
# vi /usr/local/etc/postfix/aliases<br />
<br />
添加： <br />
<br />
llzqq.nero.3322.org:/var/spool/virtual/nero.3322.org/llzqq<br />
<br />
执行下面的命令，生成 aliases.db: <br />
<br />
# cd /usr/local/etc/postfix<br />
# postalias aliases<br />
<br />
<br />
<br />
7. 配置 vm-pop3d 使其开机自动执行 <br />
<br />
# cd /usr/local/etc/rc.d<br />
# mv vm-pop3d.sh.sample vm-pop3d.sh<br />
<br />
配置 openwebmail 支持 nero.3322.org 域，创建下面的文件：<br />
<br />
# vi /usr/local/www/cgi-bin/openwebmail/etc/sites.conf/nero.3322.org <br />
<br />
=========================== nero.3322.org =======================<br />
auth_module auth_vdomain.pl<br />
auth_withdomain yes <br />
mailspooldir /var/spool/virtual/nero.3322.org<br />
use_syshomedir no <br />
use_homedirspools no <br />
enable_autoreply no <br />
enable_setforward no <br />
enable_vdomain yes <br />
vdomain_admlist llzqq //这里<a target="_blank" href="#" class="UBBWordLink">设置</a>了这个域的管理员<br />
vdomain_maxuser 500 <br />
vdomain_vmpop3_pwdpath /usr/local/etc/virtual<br />
vdomain_vmpop3_pwdname passwd <br />
vdomain_vmpop3_mailpath /var/spool/virtual <br />
vdomain_postfix_aliases /usr/local/etc/postfix/aliases <br />
vdomain_postfix_virtual /usr/local/etc/postfix/virtual <br />
vdomain_postfix_postalias /usr/local/sbin/postalias <br />
vdomain_postfix_postmap /usr/local/sbin/postmap <br />
# quota设置部分<br />
quota_module quota_du.pl<br />
quota_limit 52400 //定义了邮箱大小<br />
quota_threshold 85 <br />
delmail_ifquotahit no <br />
delfile_ifquotahit no<br />
=========================== nero.3322.org =======================<br />
<br />
# mkdir -p /var/spool/virtual/nero.3322.org <br />
# chown nobody /var/spool/virtual/nero.3322.org <br />
# chgrp mail /var/spool/virtual/nero.3322.org <br />
<br />
# mkdir -p /usr/local/etc/virtual/nero.3322.org <br />
# touch /usr/local/etc/virtual/nero.3322.org/passwd <br />
# chmod 644 /usr/local/etc/virtual/nero.3322.org/passwd <br />
<br />
# htpasswd /usr/local/etc/virtual/nero.3322.org/passwd llzqq<br />
# chmod 755 /usr/local/www/cgi-bin/openwebmail/etc/users <br />
<br />
# sync<br />
# reboot<br />
<br />
8. 最后通过浏览器登陆到OPENWEBMAIL<br />
<br />
http://nero.3322.org/cgi-bin/openwebmail/openwebmail.pl</p>

1.1 更新病毒库<br />
<br />
# /usr/local/etc/rc.d/clamav-freshclam.sh start<br />
<br />
2.0 <a target="_blank" href="#" class="UBBWordLink">安装</a>amavisd-new<br />
<br />

============================== amavisd.conf ===============================<br />
<br />
2.1 要启动clamav和amavisd-new需要配置一下/etc/rc.conf<br />
<br />
# vi /etc/rc.conf<br />
<br />
spamd_enable="YES"<br />
amavisd_enable="YES<br />
clamav_clamd_enable="YES"<br />
<br />
<br />
3.0 由于在<a target="_blank" href="#" class="UBBWordLink">安装</a>amavisd-new时spamassassin被一起<a target="_blank" href="#" class="UBBWordLink">安装</a>了下面对其进行配置<br />
<br />
3.1 建立过滤规则：<br />
<br />
# cd /usr/local/etc/mail/spamassassin<br />
# env LANG=C vi local.cf<br />
=============================== local.cf ===============================<br />
# SpamAssassin config file for version x.xx<br />
# generated by http://www.yrex.com/spam/spamconfig.php (version 1.01)<br />
<br />
# How many hits before a message is considered spam.<br />
required_hits 4.0<br />
<br />
# Whether to change the subject of suspected spam<br />
rewrite_subject 1<br />
<br />
# Text to prepend to subject if rewrite_subject is used<br />
subject_tag *****SPAM*****<br />
<br />
# Encapsulate spam in an attachment<br />

<br />
# Use terse version of the spam report<br />
use_terse_report 0<br />
<br />
# Enable the Bayes system<br />

# - chinese english <br />
ok_languages zh en <br />
<br />
# Mail using locales used in these country codes will not be marked<br />
# as being possibly spam in a foreign language.<br />
ok_locales en zh<br />
score SUBJ_FULL_OF_8BITS 2<br />
score NO_REAL_NAME 4.0<br />
=============================== local.cf ===============================<br />
<br />
3.2 下载新的垃圾邮件地址列表文件<br />
<br />
# cd /usr/local/share/spamassassin<br />
# fetch http://anti-spam.org.cn/rules/sa/55_diy_score.cf<br />
<br />
<br />
4.0 对POSFIX进行配置，在他的配置文件中添加下面的一些内容<br />
<br />
# vi /usr/local/etc/postfix/master.cf<br />
<br />
---------------------- master.cf ---------------------<br />
smtp-amavis unix - - n - 2 smtp<br />
-o smtp_data_done_timeout=1200<br />
-o disable_dns_lookups=yes<br />
<br />
127.0.0.1:10025 inet n - n - - smtpd<br />
-o content_filter=<br />
-o local_recipient_maps=<br />
-o relay_recipient_maps=<br />
-o smtpd_restriction_classes=<br />
-o smtpd_client_restrictions=<br />
-o smtpd_helo_restrictions=<br />
-o smtpd_sender_restrictions=<br />
-o mynetworks=127.0.0.0/8<br />
---------------------- master.cf ---------------------<br />
<br />
# vi /usr/local/etc/postfix/main.cf<br />
<br />
content_filter = smtp-amavis::10024<br />
<br />
好了，现在一个基于FreeBSD的功能相对完整的邮件<a target="_blank" href="#" class="UBBWordLink">服务</a>器就建立起来了，虚拟域的管理员可以登陆OPENWEBMAIL进行用户的添加、删除等<a target="_blank" href="#" class="UBBWordLink">操作</a>，虚拟用户可以通过OPENWEBMAIL修改自己的密码。
