Except that this is a directory, not a file....  :-)

A bit of experimentation suggests that "chmod 7500 .procmail" are the permissions involved, which are silly.  No group permissions enabled means setgid is meaningless, and I don't see any value for using the sticky bit here, either.  Try using 0500, 0700, or maybe 4500/4700 instead.
