Mail rejected by Hotmail
I've a Postfix + Courier mail server and everything was working fine but recently I am experimenting some issues when I try to send an e-mail to "any" @hotmail.com address. Mail is automatically rejected with the following information:

Any idea or suggestion?
The way i did it was to set the email to go through as HTML rather than plain text. Something to try if its not working. I spent hours mucking about with DNS records, but in the end this worked ok.
I also set a SPF record that might be worth doing if ur still having trouble,
You can also look at using DKIM if its still not working
