Hi All,

After some brief research, I found out that removing "ms-exch-smtp-accept-authoritative-domain-sender" permission in Exchange server able to prevent anonymous users sending mail using your domain.
If we have multiple internal applications that need to send notification emails, will this type of emails get blocked also if remove the aforementioned permission?
Example: our domain - abc.com
                 oracle apps can send emails using oracle@abc.com currently

Thanks.

If you have internal applications then the way to get round it is to have a separate Receive Connector for the internal applications which do not have that permission change. The permission change you have identified is a per receive connector change, so using a separate connector (with the connection restrictions applied so it is only used internally) avoids the problem.
