I'll take a stab at this:
Attempting to resolve a.b.c.d.e.f.g.h.i
If you get back a return value from DNS that says
"Authoritative answer, a.b.c.d.e.f.g.h.i does not exist"
Bounce the mail.
If you get back a return that says
"Resolving a.b.c.d.e.f.g.h.i timed out without a return"
Queue the mail.
This also works for i, h.i, g.h.i, f.g.h.i, etc.
