Isn't that the same a just removing those from /etc/aliases? They will
fail since they don't get directed.
My concern is that an alias might be in there because some *local*
process sends email there.
Is there a way in Exim 3 to select/limit a router based on where the
mail is coming from? I.e. allow locally generated mail and mail from
localhost and my local LAN?
