No, a "de-commissioned" SMTP server will return TCP RST packets to
connection attempts on port 25.
Any idiot configuring a de-commissioned or "out-of-service" SMTP server
to return any 5xx response gets what he or she deserves -- no e-mail.

No, do not do that because doing so would be wrong. Any 5xx is an
indication of a _permanent_ delivery failure and _MUST_ be treated as
such.
Please everyone quit trying to invent lame exuses for this misfeature!
