[exim] Run command on temp failure

I work in a sub-division of a parent company. My Exim server hands all emails to my parent company's email MTA for delivery. I should ALWAYS be able to talk to my parent email MTA, but if I can't (network failure, host down, etc.), i.e. a temp failure during a delivery, I'd like my Exim to run a command (or generate a new email or something). Is there any way to do this?? Maybe something with fallback_hosts ??

I know that this is something more akin to monitoring and various monitoring packages might be able to handle this better, but I'm hoping I could get Exim to do something too.

Thanks,

Dan
