Non Deliverable Email

I have ISERIES both are running V5R1.  

On one box, when an email is sent out that has an undeliverable email
address, a file is placed on the IFS drive in the directory:
\ROOT\QTCPTMM\MAIL\NONDELIVER.

A sample of the file is below:

On the other box, when an undeliverable email is sent, this file is not
on the IFS. 

Does anybody know how first configure it to create the files, and second
how I direct them to the directory on the IFS.


Thanks
