Sujet: Patch for Exim 1.59 to deliver via NFS under Linux
The following patch finally did the trick for me. I dont think this is
clean. Linux seems to cache the inode information locally and so the field

statbuf.st_nlink

never reaches the value 2 which is required for the successful completion
of the lock.
