在FreeBSD上建立一个功能完整的邮件服务器

第一部分：安装邮件服务器：postfix+vm-pop3d+openwebmail

以下的安装在FreeBSD 5.2.1系统上完成

1．更新 ports

# cvsup -gL 2 -h cvs p/ports-supfile

up.freebsdchina.org /usr/sha

re/examples/cvsu

2. 安装 openssl+apache 服务器

# cd /usr/ports/security/openssl

# make install

# make clean

# cd /usr/ports/www/apache2

# make install

# make clean

# vi /etc/rc.conf

apache2_enable="YES"

3. 安装 openwebmail

# cd /usr/ports/mail/openwebmail/

# make WITH_QUOTA=yes install

# make clean

4. 安装 postfix ，在安装过程中用yes回答提出的问题

# cd /usr/ports/mail/postfix/

# make install

# make clean

# vi /etc/rc.conf

为了能启动postfix加入：

sendmail_enable="YES"

sendmail_flags="-bd"

sendmail_pidfile="/v

ar/spool/postfix/pid/master.

pid"

sendmail_outbound_enable="NO"

sendmail_submit_enable="NO"

5. 安装 vm-pop3d

# cd /usr/ports/mail/vm-pop3d

# make install

# make clean

6. 配置 postfix

# vi /usr/local/etc/postfix/main.cf

添加：

virtual_alias_maps=h

ash:/usr/local/etc/postfix/v

irtual

alias_maps=hash:/usr/local/etc/p

ostfix/aliases

default_privs=nobody

allow_mail_to_commands = alias,f

orward,include

allow_mail_to_files

= alias,forward,include

下面我加入一个 nero.3322.org 的

虚拟域，并添加一个用户llzqq

# vi /usr/local/etc/postfix/virtual

添加：

nero.3322.org anything //之间用[tab]

[email protected]

llzqq.nero.3322.org //之间用

[tab]

执行下面的命令，生成 virtual.db：

# cd /usr/local/etc/postfix/

# postmap virtual

# vi /usr/local/etc/postfix/aliases

添加：

llzqq.nero.3322.org:

/var/spool/virtual/nero.3322

.org/llzqq

执行下面的命令，生成 aliases.db:

# cd /usr/local/etc/postfix

# postalias aliases

7. 配置 vm-pop3d 使其开机自动执行

# cd /usr/local/etc/rc.d

# mv vm-pop3d.sh.sample vm-pop3d.sh

配置 openwebmail 支

持 nero.3322.org 域，创建下

面的文件：

# vi /usr/local/www/cgi-bin/open

webmail/etc/sites.conf/nero.3322.org

=========================== nero

.3322.org =======================

auth_module auth_vdomain.pl

auth_withdomain yes

mailspooldir /var/sp

ool/virtual/nero.3322.org

use_syshomedir no

use_homedirspools no

enable_autoreply no

enable_setforward no

enable_vdomain yes

vdomain_admlist llzqq //这里设置了这个域的管理员

vdomain_maxuser 500

vdomain_vmpop3_pwdpa

th /usr/local/etc/virtual

vdomain_vmpop3_pwdname passwd

vdomain_vmpop3_mailpath /var/spo

ol/virtual

vdomain_postfix_alia

ses /usr/local/etc/postfix/a

liases

vdomain_postfix_virt

ual /usr/local/etc/postfix/v

irtual

vdomain_postfix_postalias /usr/l

ocal/sbin/postalias

vdomain_postfix_post

map /usr/local/sbin/postmap

# quota设置部分

quota_module quota_du.pl

quota_limit 52400 //定义了邮箱大小

quota_threshold 85

delmail_ifquotahit no

delfile_ifquotahit no

=========================== nero

.3322.org =======================

# mkdir -p /var/spoo

l/virtual/nero.3322.org

# chown nobody /var/

spool/virtual/nero.3322.org

# chgrp mail /var/spool/virtual/

nero.3322.org

# mkdir -p /usr/loca

l/etc/virtual/nero.3322.org

# touch /usr/local/etc/virtual/n

ero.3322.org/passwd

# chmod 644 /usr/local/etc/virtu

al/nero.3322.org/passwd

# htpasswd /usr/loca

l/etc/virtual/nero.3322.org/

passwd llzqq

# chmod 755 /usr/loc

al/www/cgi-bin/openwebmail/e

tc/users

# sync

# reboot

8. 最后通过浏览器登陆到OPENWEBMAIL

http://nero.3322.org/cgi-bin/ope

nwebmail/openwebmail.pl

第二部分：防病毒、垃圾邮件：clamav+amavisd-new+spam

1．0 安装clamav:

# cd /usr/ports/security/clamav

# make install

# make clean

# vi /usr/local/etc/clamav.conf

整的邮件服务器就建立起来了，虚拟域的管理员可以 等操作，虚拟用户可以通过OPENWEBMAIL修改自己的
