I have tried even abuse@ and postmaster@ and it refuses complaining the address is in use. I believe the 'already in use' simply means the address even as a mail account exists on the server. The only addresses that I can get to take is either a non existent email address belonging to any domain on the server, or a valid email that is not hosted on the server.
In my case I don't have any clients. There is only 1 user on the system, the admin housing our domains.
I can understand as per the KB, it wants a unique address different for the admin from anything else, but surely an unused address on any domain suits this requirement. I searched through the PSA database and the addresses I tested purely only exist as email addresses, not assigned anywhere else.
I even tried creating a new email address of admin@domain only to have it refused as available. However once the address is removed from the system, I can use admin@domain.
I don't think this is proper functioning, unless it's pure purpose is to force the admin to have an address external to the server, in which case the KB needs to be changed to express this, or simply add a checkbox allowing you to allow a hosted email address as the administrator.
