I run MS Windows 2000 Exchange Server.
Just added two users and created mailboxes for them, Logged on as well so mailbox is created.
There are mx records for this.
I have run the RECIPIENT UPDATE Service and REBUILT the tables as well.
But sending mail from outside to these mailboxes results in this error message:
PERM_FAILURE: SMTP Error (state 13): 550 : Recipient address rejected: User unknown in relay recipient table
Anyone know of an answer?
