Add IP Blocklist provider using Powershell in Exchange 2007

Add-IPBlockListProvider -Name zen.spamhaus.org -LookupDomain zen.spamhaus.org -AnyMatch $True -Enabled $True -RejectionResponse “Your IP is blacklisted! http://www.spamhaus.org

This script adds new provider called zen.spamhaus.org, makes lookups to zen.spamhaus.org and it works on any reply (127.0.0.1,2 …), it does enable this provider and it sets response that is sent to sender.
