Theoretically you are right. SMTP by itself does not guarantee
much of anything. But using something like the well (C-)written
highly modular 'qmail' on both sides might make it easy to be sure that
a message has been sent and received. You should prefer peer-to-peer
relaying instead of sending it through several hops.
I am pretty sure that you can get guarantees without having to resort 
to implement TCP over mail :-) 

I admit that i haven't tried such a setup myself. But i would definitely
give it a look especially because qmail is - apart from highly
secure - fast and very easy to configure.
