 PH/43 Yet another patch from the Sieve maintainer.
 
 PH/44 I found a way to check for a TCP/IP connection going away before sending
-      the response to the final '.' that terminates a message. At this time,
-      there should not be any pending input - the client should be waiting for
-      the response. Therefore, a select() can be used: if it shows that the
-      input is "ready", there is either input waiting, or the socket has been
-      closed. Both cases are errors. (It's a bit more complicated than this
-      because of buffering, but that's the essence of it.) Previously, Exim
+      the response to the final '.' that terminates a message, but only in the

+      any further data because there won't be any more messages to send. A call
+      to select() can be used: if it shows that the input is "ready", there is
+      either input waiting, or the socket has been closed. An attempt to read
+      the next input character can distinguish the two cases. Previously, Exim
       would have sent an OK response which the client would never have see.
-      This could lead to message repetition. This fix should cure that.
