+JH/15 When PIPELINING, synch after every hundred or so RCPT commands sent and
+      check for 452 responses.  This slightly helps the inefficieny of doing
+      a large alias-expansion into a recipient-limited target.  The max_rcpt
+      transport option still applies (and at the current default, will override
+      the new feature).  The check is done for either cause of synch, and forces
+      a fast-retry of all 452'd recipients using a new MAIL FROM on the same
+      connection.  The new facility is not tunable at this time.
