Thanks again Noel! You've been a great help in determining the cause of
my issue. Just want to clarify one thing, I tried setting up the
relay_recipients as you suggested once a while back for one domain
getting slammed. I did exactly as you describe above, but I also added
'example.com REJECT' after all the OK entries for each user. Is that
needed?
