Hello,

I need to know because Windows Live Hotmail blocking my IP
We use reverse DNS, Sender ID affiliate and SPF record.
I contacted with the support of Microsoft and the only thing responded thank you very much.
My IP is not on any list of SPAM

This is the mistake:

SMTP error from remote mail server after MAIL FROM:<mail> SIZE=2420:
host mx2.hotmail.com [65.54.244.40]: 550 DY-002 Mail rejected by Windows Live Hotmail for policy reasons. The likely cause is a compromised or virus infected server/personal computer. 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

Thanks very much.

Can you be more specific, that does not make sense. Did you try doing everything on the postmaster page?

Hello eth00,

Thank you for your reply.

Yes, made all the recommendations given in Hotmail posmaster page.
Now, I find that my IP are listed backscatterer.org

Have you looked into why it was listed on that page? Perhaps you do have a site spamming.


You also should remember that your site might be greylisted, if nothing bad comes from it for a few days you may get unbanned.

I'm having the same problem.. and I don't have my ip listed anywhere..

What should I do?

Here is the log file:
