在用spamassassin来反垃圾邮件时有些问题

# These should be safe assumptions and allow for simple visual sifting

配置完成后spamassassin能够正常启动,并监听783端口,但无法做到邮件过滤(中英都不行)
了解不深不知原因在哪

另外问下perl-Razor-Agent-2.40-2.i386.rpm这个包的作用,是否必须安装,
还有以下模块作用:
perl-Time-HiRes
perl-Digest-SHA1
perl-HTML-Parser
perl-DB_File
perl-HTML-Tagset
perl-Razor-Agent
perl-DBI
perl-Net-DNS
perl-URI
