The way we have Exim installed, testing shows that indeed a delivery
delayed message is sent out if the primary MX is down for the 24 hours
after the message arrives in the Exim-run secondary MX. There's no
indication that Exim was serving a secondary role, unless one studies the
To: address vs the identity of the Mailer-Daemon vs the MX records.

Since today's typical mail sender merely faints when getting one of those
messages, and calls tech support upon recovery, you can expect that few
will study the message that closely.
