So "almost no protection" against corruption is "good enough" for you, then?

Assuming no NFS (in which case the problem is worse), the vim warning is
only useful if mail is delivered while you edit.  You can still be writing
out the file and then have a new mail be delivered before your vim write
is complete.  (or if vim uses a tmp file and does an atomic rename, you
can lose mail instead of corrupting the mbox)
