I just configured IMF on Exchange 2003. After doing so, other servers within the LAN are receiveing NDR's when trying to send SMTP traffic to the Exchange box. I've added our internal LAN subnet to the Global Sender ID and Connection Filter Configuration settings. Is there any thing else I'm missing.

Have you added the IP addresses of your internal servers to the Perimeter IP List and Internal IP Range Configuration?  (General Tab of Message Delivery Propertie)

Have you got the Intelligent Message Filtering Action set to Reject or No Action?
If the former, please change it to No Action and test again.

IMF was set to reject, so I change the setting to No Action and performed the Telnet session. With the setting set to No Action, the message was sent and I received it in my Junk E-Mail. Is it possible to have the setting at Reject but allow from internal servers.

Did you restatr the Simple Mail Transfer Protocol (SMTP) service after setting up the filtering?
If not, please restart it and then change the No Action setting back to Reject.
Please test again.
Do you have any spam filtering softweare on the server?

I set IMF to Reject and restarted Simple Mail Transfer Protocol (SMTP). My Telnet test rejected the message once again.
Yes I do have AntiSpam software loaded on the Exchange server. It is Symantec Mail Security for Microsoft Exchange Version 6.0.8.262

Did you enable Sender ID Filtering on the SMTP Virtual Server?  Are all the items checked?  If not - please check them all and restart the SMTP service again, then test again.
With the SMSMSE installed, you should be able to leave the IMF set to No Action and let SMSMSE deal with the spam, but it is another useful layer of filtering.

Well it's not exactly working as it should do but you do have a workaround.
Have you downloaded all Windows Updates for the Exchange Server? - go back several times if you have any updates to download until none left.
