In Exchange 2010 Accepted domain wizard, I see 3 options:
Internal Relay Domain
External Relay Domain.
the way it is explained, I understand that if I select Internal Relay Domain, it will also cover the function of Authoritative Domain, because it says "Email is delivered to Recipient in this Exchange Organiztaion" the same sentence exists for the Authoritative Domain.
External Relay domain explanation says "Emailed is relayed to an email server outside this Exchange Organization" the same sentence exists for the Internal Relay domain.
it sounds like if I select Internal domain it will also cover the function of Authoritative Domain
if I select External Relay Domain it will also cover the function of Internal Relay Domain.
Any clearer explanation than Microsoft ?
