 TF/01 Added support for Client SMTP Authorization. See NewStuff for details.
 
+PH/01 When a transport filter timed out in a pipe delivery, and the pipe
+      command itself ended in error, the underlying message about the transport
+      filter timeout was being overwritten with the pipe command error. Now the
+      underlying error message should be appended to the second error message.
