You're missing half of the picture.  If you looked in your LISTSERV(tm)
log for the same time, you'd see the corresponding activity there too.

>>> [log in to unmask] 03/02/04 02:07PM >>>
I have been going over my SMTP logs and noticed something is sending
messages to [log in to unmask] with the subject of Output of your
job
"SAT-######/#### (not sure if the number is random or not but they
appear to
be sequential).  The sender field is blank.  Who is this LVMON and why
is
it/he/she getting messages from my listserv (if that's where it's
coming
from)?

Thanks
