But you can't really automate that. A lot of people have systems that will systematically tell you that they've been trying to talk to Joe's PC for 15 minutes but failed, don't worry they'll keep trying. One posting = one bounce, you get your 20 bounce limit every day. If you belong to the "that's YOUR system and YOUR problem" camp, setting the user NOMAIL is fine. If on ther other hand you want some leniency, this won't do. The same number of errors would probably lead you to set the user NOMAIL if they were "mailbox full" type of things. Eric
