标题: Email Send Failure

如图,

有哪位高手可以解释下？

事情是这样开始,

[email protected] send email 给 [email protected]

@example1 用的是 Microsoft Exchange e mail service provider,
@example2 用的是third party Email service provider.

当 [email protected] send email 给 [email protected] user 时 , [email protected]就出现以上图片的bounce back error message了.
这个问题不是 [email protected] 发生而已,  [email protected] 的其他user 发 email 给 [email protected]的时候也是发生这个bounce back.

看来是Email hosting 那边发生问题, 我问我们的ESP example2.com 的他说他们那边没问题?
然后叫我们问 [email protected] 的 IT 部门, 他们的回复也是说他们那边没问题.
请问到底我该怎么解决??

附上ERROR CODE:
