As in #4473: if needed, I'll redo the patch into a small
series. I've cut and pasted the following.
As for the shutdown before close, it's needed to let the server know
we are leaving, instead of waiting until socket timeout. This is the
reason I need to keep the reference to the wrapped socket.
You don't usually configure maildrop servers to limit the number/rate of
connects as you do on smtp servers; still, you could get into problems
with stateful firewalls or the like.
As for the last comment, I'll gladly look at your changes and try to
copy^H^H^H^Hbackport them.
