My guess is that it's a non-delivery message attempting to be sent, but the
originating address is a spammers phony address, so it doesn't go out

Dear List, 

I am running Exchangr 5.5 sp4 onNT4 sp6a (128bit). I have secured the server
against spam (What I think). But whenever I check the outbound queue in the
IMS, there lots of ambigous e-mails being seen. 

An example is: 

A mail message could not be sent because the following host is unknown:  
The message that caused this notification was: 

      To:       <bounce-110205856-2580@xxxxxxxxxxxxxxxxxxx> 
      From:     <> 
      Subject:  Undeliverable: Need $24,000 in 24 hours? 

I don't know where these mail are being generated from. 

Any Ideas....
