Is there a loading limit in your arsenal against DoS attacks? Is
there such a thing as resource limits even for a Modern OS? And is it
reasonable for the CS client to pass the cost burden on the receiver
to solve what is only a client problem?
I think you're ignoring the points others have made that a connection cache
benefits both sides, since establishing a connection is a (relatively)
expensive action at both ends, especially if SMTP AUTH or STARTTLS are in use.
It doesn't strictly benefit the sender.
Let them connect again if
they wish to send another message.
I think you wouldn't like the performance impact of clients doing that across
the board.
