> root can't open a file?  Huh?  Is your sendmail not setuid root?

That usually means the file is mounted by NFS, since one of the thousand
band-aids on NFS turns root into "nobody" across NFS mounts unless you set
mount options carefully. 

If this sounds like a security feature that a third-grader could defeat, 
you understand it correctly.
