That implies that something opened up a network socket to spamd, then closed
the socket before either sending any data, or sending any data that spamd
expected.

I see that at my installations when our monitoring software connects to make
sure that spamd is still running/responding; you might also see that if
someone were to open up a telnet connection to the spamd socket.
