在FreeBSD上建立一个功能完整的邮件服务器(POSTFIX)

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 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
