   I'd have to get back to you on this. I had asked this question of our
   sysadmins and they gave me the above answer. I'll ask them for a more precise
   answer.

Here is their reply:

It was literally "root@empty", according to the mail server logs. The 
mail servers could not resolve "empty" as a host name and rejected the 
message.
