hotmail blocking my mail server

Hello. I could use some help figuring out a problem with our company mail server. Apparently it has been used to send spam and as a result we can not longer send email to customers with Hotmail addresses. Can you help me figure this out? Thank you for your assistance.

Hi Carl,

The first thing to check is the mail logs on your server to get the exact error messages and look for signs of an ongoing spam problem.

There are a few likely sources of the spam including infected workstations in your network, a compromised form on a web site, compromised user credentials, an accidental open relay, and/or backscatter.

After you find and fix the problem monitor your sender score. When you score is back above 60 use this information to open a ticket with Microsoft - Hotmail Blacklist
