In the original post you said:
Suppose some device at [C] tries to send me mail, and at the time it chooses to attempt delivery, there's a network problem which prevents traffic from getting through. It instead delivers to the backup MX at [B]. There is no network problem between [B] and [A], so mail is forwarded on straight away.
So there is an MTA in both networks [A] and [B].
Then I said:
Please tell us that both [A] and [B] know all your users and domains (in other words: they reject e-mails for non existent users during the SMTP session).
And you said:
[A] and [B] are networks, not mail servers.
Ah, but I also said:
I suspect the world has greater things to worry about than how I manage the servers which handle my own mail.
I realise you really want to talk about this, but really, I'm not interested. No doubt you will draw conclusions about this, but you may find that the world will thank you for keeping them to yourself. Joe
