A message from <admin@5sqy.com> to:
-> huangyaoshifog@126.com

was considered unsolicited bulk e-mail (UBE).

Our internal reference code for your message is 01020-

06/1XU-mIF3WhlR

The message carried your return address, so it was

either a genuine mail
from you, or a sender address was faked and your e-mail

address abused
by third party, in which case we apologize for undesired

notification.

We do try to minimize backscatter for more prominent

cases of UBE and
for infected mail, but for less obvious cases of UBE

some balance
between losing genuine mail and sending undesired

backscatter is sought,
and there can be some collateral damage on both sides.

Return-Path: <admin@5sqy.com>
Message-ID: <20081011070803.DC8251BF6C5E@5sqy.com>

Delivery of the email was stopped!
观察附件发现 可能 是 DNS错误，这时 赶紧ping 5sqy.com，发

现出现另外一块网卡的IP地址，这时发现邮件系统MX指向的IP和

实际5SQY.COM指向的IP不一致，所以mta认为这是一个

unsolicited bulk e-mail (UBE).  就是假邮件，或者垃圾邮件

，或者作弊邮件的意思。

找到了错误，赶紧修改，发现原来/etc/hosts这个文件，将

5sqy.com这个域名指向了另外一块网卡的IP地址，所以出现了这

个 错误 ，赶紧修改此文件，于是就 解决了这个错误 。
