I do not agree.
I think it is not a good idea to allow my client see a warning about my
server unavailability.

The MX bkp server just cache your e-mails while you are off-line.
It is not routine, it is for a emergency.

The relay is closed and it send just for your MX "master", when
available.

Is there any problem here?

TIA.
