Interview Question in Internet Information Server


 

Interview Question :: Help? IP and Email failing to send to windows live hotmail? five star for best helpful answer

Alright, first a little background. Today I sent my mother an email from a school computer, and she checked it on her work computer, and tried to respond, but instead got the following error message:

"Your message has encountered delivery problems to the following recipient(s):

____________@hotmail.com
(Was addressed to ________@hotmail.com)
Delivery failed after 1 attempts within 0 hours and 0 minutes 550 SC-002 Mail rejected vy windows Live Hotmail for policy reasons. The mail server IP connecting to Windows Live Hotmail has exhibited namespace mining behavior. If you are not an email/network admin please contact your E-mail/Internet Service Provider for help. Email/network admins, please visit http://postmaster.live.com for email delivery information and support

No recipients were successfully delivered to."

Ok, can someone tell me what this means? And why it happened? Thanks in advance, I really appreciate it!
