Specifics:
Silicon Graphics IRIS 3030 running SGI's UNIX revision 3.5
(SYS V.2 plus BSD 4.[23] extensions, including BSD mailer)
The df?????? file that my machine was trying to return contained:

I will not bog down the net with my sendmail.cf program. It otherwise
works, and was pulled off of an ULTRIX 2.0 site which occassionally
has the same trouble with mail bouncing.....
Has anyone seen this particular peculiarity before?
I would greatly appreciate any pointers.....
