In GNU Emacs 19.26.1 (sparc-sun-sunos4.1.3, X toolkit) of Thu Sep 8
1994 on jello

Why does RMAIL only use locking (via the movemail program) on the file
in /usr/spool/mail (or wherever rmail-spool-directory is)?  Emacs
users at our site sometimes use either deliver or procmail to deliver
new mail into various folders in their login directories, then read
this new mail with RMAIL.  Since RMAIL doesn't use movemail to lock
these files before reading the new mail from them, there is a chance
that their mail files will be corrupted (and in fact this does happen
from time to time.)

I see that rmail-insert-inbox-text goes to particular trouble so that
it only calls movemail when the mail is in rmail-spool-directory.  It
would be nice if there was a variable one could set to make RMAIL
always use movemail.
