I need to add a domain to our lotus Notes mixed R5 and 4.6 environment. This domain needs to be able to access a replica of our NAB and replicate with other NABs on our other Notes named servers. We need to allow this domain to use the replica of NAB to send/address email but we want to limit or not allow them to look at or edit any other aspect of the NAB ex servers ACLs e.t.c. We also want to make sure our network is secure. Any ideas?
