What IP is used for the validity plugin?

Hi!

I am beginnig  to se validity check errors in my spam processing:

 0.4 RCVD_IN_VALIDITY_CERTIFIED_BLOCKED RBL: ADMINISTRATOR NOTICE: The
                            query to Validity was blocked.  See

So I created an account with them but still see the errors. Wha I asked them they say they do not see my
public IP anywhere. Are the SA Validity queries coming from somewhere else?
