1、测试amavisd端口10024

postfix将邮件发给内容过滤器amavisd:10024

[root@mail ~]# telnet localhost 10024
Trying ::1...
Connected to localhost.
Escape character is ‘^]‘.
220 [::1] ESMTP amavisd-new service ready
ehlo localhost
250-[::1]
250-VRFY
250-PIPELINING
250-SIZE
250-ENHANCEDSTATUSCODES
250-8BITMIME
250-DSN

quit
221 2.0.0 [::1] amavisd-new closing transmission channel
Connection closed by foreign host.

成功

2、测试postfix端口10025连接

amavisd调用SA或clamd扫描完邮件后，将邮件回注给postfix:10025

[root@mail ~]# telnet localhost 10025
Trying ::1...
telnet: connect to address ::1: Connection refused
Trying 127.0.0.1...
Connected to localhost.
Escape character is ‘^]‘.

成功

3、测试病毒邮件

（1）发送病毒邮件：

[root@mail ~]# telnet localhost 25

提示：如果设置的是拦截垃圾邮件，而垃圾邮件的tag分数设置太低，容易导致很多正常邮件

不能到达收件方；在postmaster中可以查看拦截的垃圾邮件报告。

5、留个作业给大家：

设置amavisd.conf中的垃圾过滤

$final_spam_destiny  = D_BOUNCE;

执行垃圾邮件测试，观察结果比对。
