Consider, for example, a machine which is used as a virus scanning server
or something similar (mail is passed to this box for virus filtering after
being accepted).
This box can, quite legitimately, accept connections from only one set of
machines (the primary and backup MXs for the domains it serves) and return
a 554 on connection for all other IPs - perhaps using something like
rblsmtpd or tcpwrappers.
You wouldn't want your MTA to blindly retry in such a case, for example.
"debugging" is done by humans, not machines.
