Connection filtering depends on the allow and block lists that you specified.You can specify list providers that Exchange will query. Examples of well-known list provider services include Spamhaus (http://www.spamhaus.org/sbl) and DNSBL (http://www.dnsbl.info). To use a provider, you have to create a provider by using
the Add-IPAllowListProvider or Add-IPBlockListProvider cmdlet. This requires you to
specify the name of the list provider, the DNS server the provider requires you to use,and whether the provider returns explicit status codes or a bitmask indicating why the target server is on the list.
