It's a bit early, but so far, I have received two spams... pretty
good so far, but I will report back in a couple more days...

I wanted to mention that there are some in this posting that
are recommending greylisting...  but have not said anything
about how this is implemented into sendmail... so, what is
your take on this?

Thanks-
Dan
