I am not an open relay as far as I can tell.  I am not listed on any RBL,
and I have had an email security test, and it confirmed I am not either.  I

I could check to verify this?

What configuration changes do you recommend?  I am using sendmail with the
only change to the configuration is the addition of 5 RBL's.
