We have business customers with an own mailservers asking us to provide a backup MX for their mailserver.
I'm not working for an ISP but for company helping to implement business customers to set up their own MX. I allways advise my customers *not* to use any external backup MX.
As you said, it is not necessary as external mailsystems queue anyway and we set up redundant MTAs. And as most current anti-spam systems depend (not exclusively of course) on the IP address connecting to the system, it is not very helpfull to see your backup MX connecting to you.
HTH.
