Exchange 2003 Sender ID Errors

I am getting these logs in my Application Event Log quite frequently and I can't figure out how to make them stop.

Event Type:	Error
Event Source:	MSExchangeTransport
Event Category:	SMTP Protocol 
Event ID:	7518
Date:		1/31/2012
Time:		8:26:19 AM
User:		N/A
Computer:	RLCSBS
Description:
Sender Id must be configured with a list of trusted mail servers before it can be enabled.

We are not using Sender ID filtering as we are using Postini as an external Spam Filter. We recently had a trojan on our server and had people using our server as an SMTP relay to send TONS of spam. I am pretty sure that it has been remedied but I'm not sure if they changed anything on our Exchange Server. I have looked over the entire configuration and it seems everything is ok but I keep getting these errors.

Simple enough, I forgot about that spot. Every box was checked. I assume that I don't need Sender ID Filtering or IMF enabled if I'm using Postini.

Thanks!

Sender ID Filter is disabled. None of them are checked. Should I check Apply Sender Filter and Apply Connection Filter?
