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!
