[Exim] log clutter

sorry to be a newbie pain. but how do i omit the queue run kipple from the
log and eximon? i mean

    21:13:04 Start queue run: pid=13933
    21:13:04 End queue run: pid=13933
    21:13:34 Start queue run: pid=13943
    21:13:34 End queue run: pid=13943
    21:14:04 Start queue run: pid=13953
    21:14:04 End queue run: pid=13953
    21:14:34 Start queue run: pid=13972
    21:14:34 End queue run: pid=13972

the log_level stuff is not explicit about it.
