Hotmail bounce message 550 SC-002

Mail rejected by Outlook for policy reasons. The mail server IP connecting to Outlook has exhibited namespace mining behavior. If you are not an email/network admin please contact your Email/Internet Service Provider for help.

Stop all this jibber jabber, what does it mean?

The SMTP server you are using has been abused by someone to send spam to email addresses that did not exist and were obviously "guessed".

Did I do something wrong?

No. The problem resides on the SMTP server of your outgoing email provider.

How can I fix this?

Contact your SMTP server administrator, forward your bounce message to him / her and wait for a solution. You may only have this problem with Hotmail accounts, so you may still be able to send email to other email domains / recipients.
