Okay, I feel dumb; I just found the answer in the spec (of course!). I
should have just kept reading a few more minutes! It looks like it will
work to use verify_only on the first router (the direct delivery) and
then the smarthost router listed second will handle the actual
deliveries. Untested, but this is what my reading of verify_only seems
to indicate.
If anyone can tell me that my reading is incorrect, please do. Thanks
anyway!
good times,
Vineet
