I’m using the default Document library database which comes from IBM. We’re using 6.5.5 version of Domino. I’m trying to send a notifications to a nested group (on Domino directory) and I’m getting a delivery failure report when doing this, the error says “Not authorized to send mail to this user or group”??? any idea why? I am not the one who implemented our Domino server and just joined recently. Not sure what server setup that the admin does to this server or could it be something that has been modified on the Design of the DOmino directory?
