谢谢
这个问题困扰了我很长时间
当天发帖以后
不知道哪边天神附体
居然自己摸索到了解决方法
当时还暗暗窃喜一下想上来发个攻略

钉子

哪就把你的经验整理一下发上来吧。支持原创。

解决方法和2楼一样
去掉匿名用户的ms-Exch-SMTP-Accept-Authoritative-Domain-Sender
感觉exchange2007权限控制做的太粗糙
贴一下自己写的文档（也许只有我自己看得懂）


最近发现有垃圾邮件用我们自己的邮件地址发送给我们内部用户

经查发现接受连接器(default)可以接受任何域名的邮件地址发邮件。
首先想 启用“反垃圾邮件”－“发件人ID”，通过地址反解析阻止垃圾邮件。但措施无效
通过测试，发现伪造163.com的发件人是不能通过邮件服务器检测的，但是伪造我院自己的邮件地址即可通过邮件服务器检测。
原因可能是外网DNS记录中没有增加我院邮件SPF记录，而且exchange文档中说明不对自己域名做SPF检查。

后通过对接受连接器权限研究（baidu搜索 Exchange 2007 接收连接器的安全权限），可能是因为接受连接器对匿名用户具有ms-Exch-SMTP-Accept-Authoritative-Domain-Sender权限。
运行以下命令

ms-Exch-SMTP-Accept-Authoritative-Domain-Sender权限的解释 “如果smtp接收线程没该权限，服务器会拒绝“mailfrom”中使用　权威域名　邮件。”

对匿名用户删除该权限
Get-ReceiveConnector exchange\de* | remove-adpermission -user "NT AUTHORITY\ANONYMOUS LOGON" -ExtendedRights "ms-Exch-SMTP-Accept-Authoritative-Domain-Sender"

测试，服务器拒绝匿名用户使用mydomain.com的域名发邮件，但公司oe，foxmail等因为通过域认证，仍然可以发送邮件。
