Exchange错误:smtp;550 DY-001 Mail rejected by Windows Live Hotmail for policy reasons

smtp;550 DY-001 Mail rejected by Windows Live Hotmail for policy reasons.
邮件由于安全原因被Windows Live Hotmail阻止了。我们通常不接收来自动态IP的Mail Server(由于他们经常发送未经身份认证的SMTP Email)。
http://www.spamhaus.org 列出了这些IP地址。如果你试试网络管理员的话,请向您的ISP寻求帮助。

We generally do not accept email from dynamic IP’s as they are not typically used to deliver unauthenticated SMTP e-mail to an Internet mail server.
http://www.spamhaus.org maintains lists of dynamic and residential IP addresses.
If you are not an email/network admin please contact your E-mail/Internet Service Provider for help.

后经查实原来是出网IP被列入spamhaus黑名单,其中也很明显的告诉你了http://www.spamhaus.org maintains lists of dynamic and residential IP addresses.
If you are not an email/network admin please contact your E-mail/Internet Service Provider for help.
