According to the RFC, the process for delivering messages is
something like:
o Attempt to deliver the message.
o If the delivery succeeds, quit.
o The delivery failed, check the sender of the message.
o If the sender of the message is null, quit.
o Create an error message and deliver it to the sender
*with the sender set to null* and quit.
The purpose of this is to prevent just the sort of loop you have
discovered. In order to break the loop you will need to discover
which of the above steps your system is doing incorrectly.
