We had a problem earlier today with an IMail list server at AMBIENCE.COM.AU looping mail back to LISTSERV (kind of like majordomo used to have a tendency to do), and just a few minutes ago a customer wrote in saying she was having the same problem with the same host. If this happens to you you can stop the loop by adding [log in to unmask] [log in to unmask] (or whatever variation for your specific platform--and under unix don't forget to export) followed by a restart of the server. This will stop LISTSERV from responding to imailsrv and will break the loop. It might be reasonable to add this as imailsrv@* but I'm not sure if this is the default administrative account for an IMail list server. Nathan
