On the subject of sending commands without sending mail, a related
counter is the "junk" command counter that is incremented with each
HELO, EHLO, RSET, NOOP, VRFY, ETRN command (any command that can
be repeated indefinitely without triggering an error response).
Like the error counter, this counter has a limit, and it
is reset after a successful mail delivery transaction.
