Rebooting the computer should not affect LISTSERV in any way as far as these messages are concerned. I only see two explanations: 1. The reboot causes the mail server to resubmit these messages somehow. 2. The messages were in hold status (jobh) and you have a script that renames *.jobh to *.job before restarting LISTSERV. Or of course they came back from the usenet gateway another time, etc. LISTSERV should be stopped before a system reboot for a number of reasons ranging from minor (gives it a chance to checkpoint statistics to disk, etc) to more important (makes sure no activity is interrupted in the middle - you could end up with a posting processed twice, once to half of the members and then once to everyone).
