How do you arrive at the "minimum of 4 additional automated

As you pointed out later in your reply, each faux-550 response must
be followed by an automated email message, addressed to
whatever-the-return-address was. That autoresponder message,
intended to avoid (well, diminish) false positives, outlines the
"procedure" necessary to actually send email to the address. (Mea
cupla, in the heat of the moment, I counted server responses as
messages, and I shouldn't have.) Still, for each hijacked return
address, the sheer number of automated messages being passes around
(and the corresponding burden on shared resources) is not diminished;
at best, it is merely redirected.

In an effective system I would imagine the 550 response to
include details informing the sender on what has happened,
rather than simply dropping the message.
Perzactly.
