Why are the emails sent to Hotmail rejected for policy reasons?

The mails that I or my domain users sent to Hotmail are rejected for policy reasons.

Error Codes:

# 550 SC-001 Mail rejected by Hotmail for policy reasons. Reasons for rejection may be related to content with spam-like characteristics or IP/domain reputation. If you are not an e-mail/network admin please contact your E-mail/Internet Service Provider for help.

# 550 SC-002 Mail rejected by Hotmail for policy reasons. The mail server IP connecting to Hotmail has exhibited namespace mining behavior. If you are not an e-mail/network admin please contact your E-mail/Internet Service Provider for help.

# 550 SC-003 Mail rejected by Hotmail for policy reasons. Your IP address appears to be an open proxy/relay. If you are not an e-mail/network admin please contact your E-mail/Internet Service Provider for help.

# 550 SC-004 Mail rejected by Hotmail for policy reasons. A block has been placed against your IP address because we have received complaints concerning mail coming from that IP address. We recommend enrolling in our Junk E-Mail Reporting Program (JMRP), a free program intended to help senders remove unwanted recipients from their e-mail list. If you are not an e-mail/network admin please contact your E-mail/Internet Service Provider for help.

# 550 DY-001 Mail rejected by Hotmail for policy reasons. 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. If you are not an e-mail/network admin please contact your E-mail/Internet Service Provider for help. http://www.spamhaus.org maintains lists of dynamic and residential IP addresses.

# 550 DY-002 Mail rejected by Hotmail for policy reasons. The likely cause is a compromised or virus infected server/personal computer. If you are not an e-mail/network admin please contact your E-mail/Internet Service Provider for help.

If you are a customer using the 3rd party email service or a Hotmail customer who is unable to receive emails from a particular 3rd party domain:

Contact your domain administrator and ask them to get in touch with the Hotmail Sender Support Team. They have to fill out the e-form that can be found on the following link:

http://support.msn.com/eform.aspx?productKey=edfsmsbl&page=support_home_options_form_bye-mail&ct=eformts

If you do not know how you can get in touch with your domain admin, you can use WHOIS tools to search for your contact e-mail address of your domain admin.

If you are the 3rd party Domain Administrator:

1. Please review our policies and guidelines at http://postmaster.live.com.

2. If you are in compliance, submit a support request to our Email and Delivery Filtering Services team by clicking on the link to the e-form under the troubleshooting section in the postmaster site mentioned above.
