5.7.1错误号的定义：

DSN(Delivery Status Notifications in Exchange 2000 Server)描述了三种情况：

Ø        Success (as 2.<X.X> numerical codes)

Ø        Persistent transient failure (as 4.<X.X> numerical codes)

Ø         Permanent failures (as 5.<X.X> numerical codes)

详细定义可以参见RFC 1891和RFC1893。

 Numerical Code: 5.7.1：

Possible Cause:

n      General access denied, sender access denied ? the sender of the message does not have the privileges necessary to complete delivery.

n      You are trying to relay your mail via another SMTP server and it does not permit you to relay.

n      The recipient might have mailbox delivery restrictions enabled. For example, a recipient’s mailbox delivery restriction was sent to receive from a Distribution List only and non-member’s email will be rejected with this error.

Troubleshooting: Check system privileges and attributes for the contact and

  retry the message. Also make sure you are running Exchange 2000 Service Pack

  1 or later for other potential known issues.

原因与解决方法：

出错的几种原因：

第一种解释：

《XCON: NDRs May Result Based on SMTP Configuration [Q274638]》给出的适合Exchange的解释：

发生5.7.1错误可能是由于Exchange的System Manager中的SMTP虚拟服务器的设置中没有选中“allow computers which successfully authenticate to relay”复选框。如下所示，

先打开SMTP Virtual Server的属性页的Access页：

然后点击“Relay”按钮，察看“Allow all computers which successfully authenticate to relay,regardless of the list above”是否选中：
