Hotmail Not Accepting My Server Emails

I have 2 cPanel servers with normal decent setups, and until today, HOTMAIL/LIVE is not accepting my e-mails.

There is no problem with GMAIL & YAHOO, btw.

When I mentioned not accepting my e-mails means it will always appear inside the Junk box instead of Inbox (for every domains in both servers)

I've tried to contact Microsoft support many times but they keep repeating the same thing. I've tried everything including make sure that my IP reputation is clean, and having domain keys.

I need some advise from you guys out there that has this issue before and start from sketch, what do I need to do to identify what Microsoft servers actually want from me?

Here's their 'robotic' respond.

1) Make sure that you have SPF/SIDF records in place. You
can go to [url]
for more information on this.

2) Clean up your lists. Remove those who do not want to
receive the emails. Make the unsubscribe process more visible. Hotmail
also has a sender complaint feedback loop program called the Junk Email
Reporting Program (JMRP). Enrollment in this free program will benefit
you as a sender as it will keep your email lists updated and populated
with interested Windows Live Hotmail Customers. This program will help
you to remove those Windows Live Hotmail Customers who do not want to
receive emails from your company. If you are interested in joining this

3) Ensure that there is not anything technically wrong with
your MTA. Are your DNS records updated, are you transmitting data upon
making the SMTP connection, and is the problem isolated to any specific
machines? Do your SMTP logs show any failures?

4) Segment your mailing infrastructure by IP. Marketing
email, transactional corporate email, "forward to a friend" email and
signup emails should be sent from different IP's. This will help to
identify what types of messages are being flagged by Hotmail customers.

5) Strengthen the sign up process. Confirm that you are
using a double-opt-in sign up process. This will not help in removing
existing Hotmail customers from your email lists, but it will confirm
the authenticity of those who sign-up for your email campaigns and
newsletters.

6) If you have any feedback loops setup with other ISPs,
you should look for trends to try to determine possible causes - a new
data source? New advertisement? Maybe folks signing up do not recognize
the mail?

7) Clearly mark your emails so that Hotmail customers are
able to identify quickly and easily that they requested emails from your
service.

8) Do some analysis on the data regarding complaints - look
at Hotmail customers who have never clicked, opened, responded or
bounced in any way. These poor performers could contain many bad
addresses.

9) Evaluate the frequency of your mailings. Are you making
your mailings less relevant and welcome by sending too many emails?

10) Enroll in the Sender Score program. This is the only white
list that Hotmail uses. It is owned and operated by Return Path. You can
find information about this program at

11) Please visit [url]
to verify that your IP is not being listed
on any third party block lists.
