your explanation does not get me closer to a solution then.  the 
username is actually a cover that I put in place of a real username. 
the actual username that should appear in place of the username does 
exist locally as a user account.  so if what you are saying is true then 
the mail should have been delivered but it has not.

also localhost is 127.0.0.1 according to my /etc/hosts file output.  but 
instead the localhost that is getting reolved is 10.11.12.13 .
so something is still getting Munged.  I checked hostname resolution for 
localhost from the servers listed in /etc/resolv.conf and arrive at the 
address 127.0.0.1

$ cat /etc/hosts
127.0.0.1     localhost localhost.localdomain
