Unfortunately this attitude does seem to be catching hold. I was told
recently that a secondary MX would have to stop functioning as such
because his ISP insists that he have an up to the second list of all
valid mailboxes at my site; he's not allowed to relay undeliverable
mail to me *ever*.
So much for the whole concept of a store-and-forward mail system. :-(
