"There is no users, or mailbox ... assigned to 'Postmaster'"

I dunno much about Exchange, but the relevant Internet RFCs (822, 2822)  *require*  that "postmaster@" be a valid address that reaches a human being responsible for the mail system.
Who is doing what here? Is there a sender at yahoo who sends a message to your domain ("domain.org") and gets this error message? If so, I think even Exchange puts "postmaster" as sender of the error message. And it means something is wrong with the address. As PsiCop says, someone should be assigned to receive *incoming* mail for postmaster@yourdomain.org

The sender is a yahoo user, and I agree, someone should be assigned the postmaster
Apparantly this was not done when Exchange 2000 was installed. There is no Postmaster address assigned to Administrator. I find nothing in Notificatifications either.

I think you understand the issue. I do not find any SMTPSVC log entries in the Event viewer.
Where are they located?
NOTE: the user@domain is a valid email address. This problem is only happening with one sender.
In Exchange 2003 logs can be found in
 \ProgramFiles\Exchsrvr\servername.log\yyyymmdd.log
Not very human-readable stuff, but useful.
