如何建立企业邮箱

去下一个FreeBSD 5.2.1安装上去。

以下的安装在FreeBSD 5.2.1系统上完成

1．更新 ports

# cvsup -gL 2 -h cvsup.freebsdchina.org /usr/share/examples/cvsup/ports-supfile

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="/var/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：

myhostname = nero.3322.org

mydomain = nero.3322.org

virtual_alias_maps=hash:/usr/local/etc/postfix/virtual

alias_maps=hash:/usr/local/etc/postfix/aliases

default_privs=nobody

allow_mail_to_commands = alias,forward,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]

llzqq@nero.3322.org 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/openwebmail/etc/sites.conf/nero.3322.org

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

auth_module auth_vdomain.pl

auth_withdomain yes

mailspooldir /var/spool/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_pwdpath /usr/local/etc/virtual

vdomain_vmpop3_pwdname passwd

vdomain_vmpop3_mailpath /var/spool/virtual

vdomain_postfix_aliases /usr/local/etc/postfix/aliases

vdomain_postfix_virtual /usr/local/etc/postfix/virtual

vdomain_postfix_postalias /usr/local/sbin/postalias

vdomain_postfix_postmap /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/spool/virtual/nero.3322.org

# chown nobody /var/spool/virtual/nero.3322.org

# chgrp mail /var/spool/virtual/nero.3322.org

# mkdir -p /usr/local/etc/virtual/nero.3322.org

# touch /usr/local/etc/virtual/nero.3322.org/passwd

# chmod 644 /usr/local/etc/virtual/nero.3322.org/passwd

# htpasswd /usr/local/etc/virtual/nero.3322.org/passwd llzqq

# chmod 755 /usr/local/www/cgi-bin/openwebmail/etc/users

# sync

# reboot

8. 最后通过浏览器登陆到OPENWEBMAIL

3.2 下载新的垃圾邮件地址列表文件

# cd /usr/local/share/spamassassin

# fetch

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

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

---------------------- master.cf ---------------------

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 mynetworks=127.0.0.0/8

---------------------- master.cf ---------------------

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

content_filter = smtp-amavis:[127.0.0.1]:10024

好了，现在一个基于FreeBSD的功能相对完整的邮件服务器就建立起来了，虚拟域的管理员可以登陆OPENWEBMAIL进行用户的添加、删除等操作，虚拟用户可以通过OPENWEBMAIL修改自己的密码。
