A final thought occurred to me: even though the EDS was not forwarding
incoming mail, it was still accepting the incoming messages.
Consequently, a secondary MX record wouldn't have even come into play
because, as far as external SMTP servers were concerened, there was no
outage.
There could be a setting whereby, in case of "Degraded Performance" the
connection is rejected in such a way that external SMTP servers are
forced to go to secondary MXs. How that would work is a question for
somebody smarter that me, though.
Or, there could be a web-based interface (similar to the quarantine)
where incoming queued messages could be reviewed. That's a nice
solution.
Have a nice (uptime-filled) weekend.
