Hi Nathan.. > Have you checked to see if the user actually exists? With the probe No. but from other listowners I've heard that this is happening with brand new subscribers who they know are "real" . > setting turned on, the auto-delete functionality will also send > probes if delivery errors are received for a given user. And of > course if the user doesn't exist, the probe will fail, eventually But wouldn't you get the basic error message in the daily report that says why.. like "user unknown" or one of the other coded reasons if it were doing that? All were're getting is what I forwarded to the list.. but I am still getting the other type too.. [with the error message] ........Cleo [log in to unmask]
