das mit dem häken ist so weil er die hauptadresse automatisch automatisch als primäre setzt:
Exchange 2000 must always be authoritative for the primary (bold) SMTP address on the default recipient policy. You will notice the This Exchange Organization is responsible for all mail delivery to this address checkbox is grayed out in the user interface as a result. Therefore, we must add a second recipient policy to override the default recipient policy in order to make Exchange non-authoritative on the new domain. Set the new address space as primary on the new recipient policy and deselect the This Exchange Organization is responsible for all mail delivery to this address checkbox. Leave the existing domain as a secondary proxy address and make sure its This Exchange Organization is responsible for all mail delivery to this address checkbox is selected.
daher ist das normal.
