Can somebody please help me with this issue. In our company we are having issues sending emails to @hotmail.com addresses. I have contacted Microsoft "Support" directly about this issue and they suggested getting our Domain hoster to publish a SPF record to get around this. I have gotten our domain hosters to do this, but it has been 4 days and the problem is still happening. Below is the error message we get when we send an email to @hotmail.com addresses; I have replaced our domain with 'EXAMPLE'.
There was a SMTP communication problem with the recipient's email server. Please contact your system administrator. sd1-ex1.EXAMPLE.NET #5.5.0 smtp;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>
Our environment is Windows 2003 server with Exchange 2003. Office 2007.
Thank you.
- Just an update: I have found out that someone is using our domain to spam, which has put us on a blacklist. The site that has us blacklisted says that there is a problem with too much 'backscatter'. Please help!

We've had similar happen, and it is hard to figure out. What happened to us is that one of our mailers got put on one of the various Realtime Blackhole Lists (RBL's) out there, which MS Live was using in their spam/not-spam decision making. We had to get delisted from the RBL before we could deliver. Microsoft was singularly NOT helpful in this, as they're loath to tell people how to circumvent their spam checking.
