[ Converted text/html to text/plain ]

This is definatly an issue with how exim-4.x works. I have been
doing testing on a RedHat 7.2 server with the mailspool mounted over
NFS. Exim-3.35 works just fine (just as you found), but any of the
exim-4.x builds do not. The all give the same error when exim tries
to deliver mail (exim -v user@domain):
LOG: MAIN
Message abandoned: spool file directory sync error while receiving
from root: Invalid argument
LOG: MAIN
Message abandoned: spool file directory sync error while receiving
from exim: Invalid argument
LOG: MAIN
Child mail process returned status 1

or (exim -d -v user@domain):

local_scan() returned 0 NULL

And yes, exim-4.x does deliver to non NFS mounts just fine. So, I
do not know what has changed between the exim-3.x builds and the
exim-4.x builds, but something has.
Until I saw this posting, I thought that I was just doing something
wrong, but I do not believe so, as I do not believe that this is a
NFS issue, I believe this is a exim-4.x NFS issue.
Does anybody have exim-4.x delivering mail to a NFS mounted
mailspool?
