 But, as I hope is clear from the above, no such thing
 happens. If the drop occurs after EOD, the mail (message)
 transaction is over already, completed by EOD.  If the drop
 occurs before EOD, the mail transaction and the SMTP session
 are abandoned and, because EOD wasn't received by the
 server, nothing is delivered.

There is of course a timing hole (as there always is): if the
connection drops after the client sent EOF but before the
client received a reply, then the client can't know if the
server is processing the message or not.

Of course, this issue was news ... in 1988.    See RFC 1047.
