Not load, but more smtpd processes waiting for a polw reply.

Useful yes, required, not really.

You can delete it (with the latest version).

This is the job of $NTTL and $NTIME in concert

       $NTTL (default: 1)
              The client is penalized for that many retries.


       $NTIME (default: 30)
              The  $NTTL  counter will only be decremented if the client waits
              at least $NTIME seconds.
