我的一台 Exchange 服务器遇到了一些奇怪的问题。
Exchange 环境如下
- Exchange 2010 是主邮件服务器（安装了 CAS、HT、MB 角色）
- Exchange 2003 仍然提供公共文件夹功能/在主服务器宕机时可以捕获任何电子邮件
- Exchange 2003 具有 Vamsoft ORF 的邮件过滤功能
- 主 Exchange 使用 Exchange Server Toolbox 进行垃圾邮件过滤
- 如果其他两台服务器都出现故障，我们有一个指向 ISP 服务器的辅助 MX
我至少收到过两个人发来的 5.6.0 NDR 电子邮件（电子邮件系统在处理此邮件时出现问题。系统不会再次尝试发送此邮件。) 正在使用的特定帐户（我将其称为用户 1）。问题是，受影响的电子邮件帐户似乎与电子邮件完全无关。
实例一
用户从 Exchange Server 收到 NDR，指出由于系统在处理邮件时出现问题（5.6.0），因此无法将邮件发送给用户 1。奇怪的是，该用户没有给用户 1 发送电子邮件，其电子邮件地址也根本没有包含在对话中。该用户不是用户 1 的代表。
实例二
另一位用户在尝试向用户 1 发送电子邮件时收到 NDR，指出该电子邮件无法再次发送到与该电子邮件完全无关的两个地址。其中一个电子邮件地址是内部的，另一个是外部的。服务器日志没有显示任何迹象表明不同用户的帐户或用户 1 的帐户尝试向发出 NDR 的帐户发送电子邮件。
谷歌搜索了半天也没找到答案。如果有人知道发生了什么，我将不胜感激。这两起案件唯一的共同点是都涉及到用户 1。
示例 NDR（实例 2）

答案1
将反垃圾邮件软件 (Exchange Server Toolbox) 更新到最新版本后，此问题不再存在。我们已经测试了一个多月，没有出现重复出现的问题
