Event Id7519
DescriptionThe originating IP address of message with ID <%1> could not be determined based on its Received headers.
Event InformationCAUSE:
This event indicates that Sender ID filtering is not able to correctly process a message. This error may occur if one of your servers is issuing non-standard receive headers. This error may also occur if you have not correctly configured the list of internal servers.

To resolve this error, do one or more of the following:

1. Ensure that the servers in front of the servers in your perimeter network are configured to correctly issue received headers.
2. Ensure that you have correctly configured the list of IP addresses to exclude from Sender ID filtering. Use the following procedure to specify the list of servers.

To specify IP address configuration data for Sender ID filtering:

You can add up to 196 IP addresses to list. To add an IP address to this list, click Add.
g. In IP Address (Mask), specify the IP addresses that you want to exclude from IP address validation. You must include all servers in your Exchange organization that process incoming SMTP mail.
