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 R
