I faced this issue when implementing our mail relay. I decided that the
client SMTP would have to wait while the relay delivered the message.
Otherwise, the relay could acknowledge the message and then crash
or discover that the destination mail server was unable to take the message.
Either way, the mail goes on the floor, hardly desirable. Acknowledgement
should mean that the message is really okay.

On the other hand, I also get multiple copies of a lot of whole and partial
messages; it seems that some hosts are less patient than others...
