I think the problem is the line break after "machine" in the subject
(actually \r\n).  This got taken to be the end of the command, which it
isn't.  I'm not sure if there's a way to get around that from python; at
the raw protocol level one could provide a prefix count of the octets.

As a work-around I truncated the subject string before the end of the
first line.  That seems to suffice.

Still wondering about the problems with edresses.  On further
examination of the spec it doesn't look as if < or > are special in the
context of a quoted string in a search command.
