Hello all,

 

   I have an Exchange 2003 org that forwards mail to a smart relay (IIS
6 Server) and quite often I see e-mails that are 0 KB in size.  If I
open one of those messages in the queue, it states:

 

From: Sender Unspecified

To: None

Subject: (No Subject)

 

Body of e-mail is blank...

 

 

They generally appear for only a few seconds before being deleted, but I
want to know where they are coming from.

 

And yes, the relay is LOCKED down to only certain approved internal
IP's.  

 

What could be causing them?

 

Thanks for your thoughts.
