+PH/29 SMTP synchronization checks are implemented when a command is read -
+      there is a check that no more input is waiting when there shouldn't be
+      any. However, for some commands, a delay in an ACL can mean that it is
+      some time before the response is written. In this time, more input might
+      arrive, invalidly. So now there are extra checks after an ACL has run for
+      HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
+      pipelining has not been advertised.
