Post subject:  Mail rejected by Hotmail
Hey,

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:

Code:

<something@hotmail.com>: host mx2.hotmail.com[65.55.37.120] said: 550 SC-001
   Mail rejected by Windows Live Hotmail for policy reasons. Reasons for
   rejection may be related to content with spam-like characteristics or
   IP/domain reputation problems. 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 (in reply to MAIL FROM command)

Final-Recipient: rfc822; something@hotmail.com
Original-Recipient: rfc822;something@hotmail.com

Either have everyone move away from Hotmail (harder than it seems...), or visit http://postmaster.live.com for their list of acceptance rules. They're a rather difficult place to send mail to sometimes, but it can be done.

I managed to get my email through to hotmail and yahoo. Theres a post about it somewhere in the SMTP mail linode forums

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

i found it quite easy to check the headers sent in the email, by using gmail, on the top right of each message there is a ajax dropdown with "show original" or something like that
