 ### Scenarios where messages from sources in the IP Allow List are still filtered

 Messages from an email server in your IP Allow List are still subject to spam filtering in the following scenarios:
 
 - An IP address in your IP Allow List is also configured in an on-premises, IP-based inbound connector in _any_ Microsoft 365 organization, **and** that Microsoft 365 organization and the first Microsoft 365 server that encounters the message both happen to be in _the same_ forest in the Microsoft datacenters. In this scenario, **IPV:CAL** _is_ added to the message's [anti-spam message headers](message-headers-eop-mdo.md) (indicating the message bypassed spam filtering), but the message is still subject to spam filtering.
