这封邮件是怎么进来的，请大虾分析

taotao

各位大虾，这是一封邮件的日志。从客户端通过POP3收到邮件后，发现收件人和抄送人都不是邮局用户，发件人是通过什么手段发送过来的。<br>

呵呵！是不是你被中转了？

taotao

goxia,你好，我在MD的安全设置中关于防止转发该加的都加了，从日志中看到发件人和收件者都是“annette.it@i-acci.org”，只是其中有多处有我公司邮局用户的名字：username@mail.XXX.com<br>
<br>
1.for <USERNAME@mail.XXX.com>; Mon, 18 Apr 2005 14:46:02 +0800<br>
2.X-MDRcpt-To: USERNAME@mail.XXX.com<br>
3.X-MDaemon-Deliver-To: USERNAME@mail.XXX.com<br>
<br>
请goxia和各大虾，帮我瞧瞧，是不是我的MD该升级了，我是6.84版的

<br>
应该是用密抄发送到username@mail.xxx.com,怪不得从客户端看不到正常的收件人，应该是这句<br>
X-MDRcpt-To: USERNAME@mail.XXX.com是密抄，但Deliver-To是递送到，却没有找到原因，请大虾们帮忙<br>

goxia

可能你的策略是这样的，在通过某种验证后，对方可以中转一类的。
