　　3.2 下载新的垃圾邮件地址列表文件

　　# cd /usr/local/share/spamassassin

　　# fetch http://anti-spam.org.cn/rules/sa/55_diy_score.cf

　　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。
