【問題】email收發

[105104]

我們公司最近出現一個問題
G公司收發信件正常 L公司收發信件也正常
G公司可以收到L公司的來信
但L公司卻無法收到G公司的來信
兩者公司都沒有被列入郵件黑名單
以下是G公司寄給L公司退信的內容

Reporting-MTA: dns; g.g.com

Final-Recipient: RFC822; [email protected]
Action: failed
Status: 4.4.7
X-Supplementary-Info: <g.g.com #4.4.7>

給你一個參考

KB裡面有關NDR 4.4.7的說明

http://support.microsoft.com/kb/284204/en-us

Numeric Code: 4.4.7

Possible Cause: The message in the queue has expired. The sending server tried to relay or deliver the message, but the action was not completed before the message expiration time occurred. This NDR may also indicate that a message header limit has been reached on a remote server or that some other protocol timeout occurred during communication with the remote server.
Troubleshooting: This code typically indicates an issue on the receiving server. Verify the validity of the recipient address, and verify that the receiving server is configured to receive messages correctly. You may have to reduce the number of recipients in the header of the message for the host that you are receiving this NDR from. If you resend the message, it is placed in the queue again. If the receiving server is on line, the message is delivered.

基本上是被對方擋掉了…
