AFAICS this message is only returned if either a timeout occurs or the
connection is dropped before the final "." of the message is received.

Since the error occurs within less than 1 second of the start of the
transmission, it can't be a timeout. So the connection is probably
dropped for some reason. It is probably best to use a packet sniffer
(ethereal works well in my experience) to check what the client and
server actually send.
