postfix能收不能发的问题，请大侠帮忙指点一下！！！

miladuo

刚配置了一个postfix的邮件服务器，在安装防垃圾软件之前，邮件服务器还是收发正常，安装完后，就发出的邮件全部退回，收邮件是正常的。望高人帮忙指点一下。
发出的邮件，退回的信息是：
来自： "Content-filter at mail.wl007.com" <postmaster@mail.wl007.com> 将该来信人加到地址本中
发给： <test02@wl007.com>
日期： Thu, 25 Sep 2008 18:32:48 +0800 (CST)
附件列表： dsn_status (0.58K)  附件保存到网络磁盘

A message from <test02@wl007.com> to:
-> miladuojx@qq.com

was considered unsolicited bulk e-mail (UBE).

Our internal reference code for your message is 02488-07/fN+Keq0bkN2G

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.

First upstream SMTP client IP address: [127.0.0.1] mail.wl007.com
According to a 'Received:' trace, the message originated at: [127.0.0.1],
  localhost.localdomain mail.wl007.com [127.0.0.1]

Return-Path: <test02@wl007.com>
From: "=?ISO-8859-1?B?dGVzdDAy?=" <test02@wl007.com>
Message-ID: <20080925102443.E8C0539C8B2@mail.wl007.com>
Subject: =?ISO-8859-1?B?MTExMTExMTExMTExMQ==?=    =?ISO-8859-1?B?MTExMQ==?=

Delivery of the email was stopped!
