16 april 1995 Ottawa What I do whenver i get a message indicating mail cannot be delivered to one of my list subscribers for any reason is issue a quiet delete of the user or all users at the affected site if the error indicates a site wide problem e.g. host unknown or connect failed. This minimizes the errors i get and allows me to retain some sanity. i really wish I could set the listserv to auto delete anyone who had any problem including 4 hour delays in receiving mail. Sometimes the list serv will autodelete someone on the first occurrance of an error but this seems rare. As far as advising the listowner of a user with a full mailbox, I also wonder at this but vax does it too and I guess the idea is to tell the ender the mail cannot be delivered and perhaps to cease sending new mail. I interpret mailbox full, file system full, disk quota exceeded and device not available as a cue to delete the subscriber immediately. If they are a local telephone call to me, i will call them to ask them to remedy the situation but at lest one system in town has a gateway tht breaks a lot and a slow admin so i just delete when the gateway breaks.
