These days most of those showing up on this report are spammers sending mail to your (private) list from a non-existent address. LISTSERV sends a message back to the phony address stating they are not subscribed and not allowed to post. Since the address doesn't exist, it bounces back to LISTSERV. LISTSERV uses a special Return-Path for each list, that way if it bounces LISTSERV knows which list it is for. So when these bounce, LISTSERV adds that non-existent address to that list's error report. There are different but similar scenarios which causes this, but this is how it happens. > In the daily error monitoring report for one of my lists, two of the > subscribers reported as being monitored don't exist.
