re-reading your reply - it looks like an ACL might work (as long as cPanel
updates don't clear them out) but would you have an example of a discard
ACL for all mail?
cPanel added a local router named LMTP this year that handles virtual
(within the server) deliveries but I don't think that has any bearing on
this issue.
There's no sparthost and no email needed at all - all our monitoring is
done via non mail methods on these servers.
Thanks,
Brian
