Appreciate the quick reply. I enabled the module, read the domain module sections in the ISPConfig 3 manual (that I bought

), and I trolled the forums a bit on the subject.
It sounds like to accomplish shelluser_blacklist like functionality I have two options using the Domain Module:
Option 1) Add a list of blacklisted domains, one-at-a-time, to my admin account in which case no one would see them (but, the admin user would on every screen where they could add a domain - ie. Email Domain Add, Site Add, Shell User Add, FTP User Add, etc.).
Option 2) Create a dummy admin/holding account where I would add each of these blacklisted domains to, one-at-a-time, to this holding account so it won't show elsewhere.
Am I correct?
